- GNU LIBRARY GENERAL PUBLIC LICENSE
- Version 2, June 1991
-
- Copyright (C) 1991 Free Software Foundation, Inc.
- 675 Mass Ave, Cambridge, MA 02139, USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the library GPL. It is
- numbered 2 because it goes with version 2 of the ordinary GPL.]
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
- This license, the Library General Public License, applies to some
-specially designated Free Software Foundation software, and to any
-other libraries whose authors decide to use it. You can use it for
-your libraries, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if
-you distribute copies of the library, or if you modify it.
-
- For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you. You must make sure that they, too, receive or can get the source
-code. If you link a program with the library, you must provide
-complete object files to the recipients so that they can relink them
-with the library, after making changes to the library and recompiling
-it. And you must show them these terms so they know their rights.
-
- Our method of protecting your rights has two steps: (1) copyright
-the library, and (2) offer you this license which gives you legal
-permission to copy, distribute and/or modify the library.
-
- Also, for each distributor's protection, we want to make certain
-that everyone understands that there is no warranty for this free
-library. If the library is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original
-version, so that any problems introduced by others will not reflect on
-the original authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that companies distributing free
-software will individually obtain patent licenses, thus in effect
-transforming the program into proprietary software. To prevent this,
-we have made it clear that any patent must be licensed for everyone's
-free use or not licensed at all.
-
- Most GNU software, including some libraries, is covered by the ordinary
-GNU General Public License, which was designed for utility programs. This
-license, the GNU Library General Public License, applies to certain
-designated libraries. This license is quite different from the ordinary
-one; be sure to read it in full, and don't assume that anything in it is
-the same as in the ordinary license.
-
- The reason we have a separate public license for some libraries is that
-they blur the distinction we usually make between modifying or adding to a
-program and simply using it. Linking a program with a library, without
-changing the library, is in some sense simply using the library, and is
-analogous to running a utility program or application program. However, in
-a textual and legal sense, the linked executable is a combined work, a
-derivative of the original library, and the ordinary General Public License
-treats it as such.
-
- Because of this blurred distinction, using the ordinary General
-Public License for libraries did not effectively promote software
-sharing, because most developers did not use the libraries. We
-concluded that weaker conditions might promote sharing better.
-
- However, unrestricted linking of non-free programs would deprive the
-users of those programs of all benefit from the free status of the
-libraries themselves. This Library General Public License is intended to
-permit developers of non-free programs to use free libraries, while
-preserving your freedom as a user of such programs to change the free
-libraries that are incorporated in them. (We have not seen how to achieve
-this as regards changes in header files, but we have achieved it as regards
-changes in the actual functions of the Library.) The hope is that this
-will lead to faster development of free libraries.
-
- The precise terms and conditions for copying, distribution and
-modification follow. Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library". The
-former contains code derived from the library, while the latter only
-works together with the library.
-
- Note that it is possible for a library to be covered by the ordinary
-General Public License rather than by this special one.
-
- GNU LIBRARY GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License Agreement applies to any software library which
-contains a notice placed by the copyright holder or other authorized
-party saying it may be distributed under the terms of this Library
-General Public License (also called "this License"). Each licensee is
-addressed as "you".
-
- A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
- The "Library", below, refers to any such software library or work
-which has been distributed under these terms. A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language. (Hereinafter, translation is
-included without limitation in the term "modification".)
-
- "Source code" for a work means the preferred form of the work for
-making modifications to it. For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control compilation
-and installation of the library.
-
- Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it). Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-
- 1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
- You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-
- 2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
- a) The modified work must itself be a software library.
-
- b) You must cause the files modified to carry prominent notices
- stating that you changed the files and the date of any change.
-
- c) You must cause the whole of the work to be licensed at no
- charge to all third parties under the terms of this License.
-
- d) If a facility in the modified Library refers to a function or a
- table of data to be supplied by an application program that uses
- the facility, other than as an argument passed when the facility
- is invoked, then you must make a good faith effort to ensure that,
- in the event an application does not supply such function or
- table, the facility still operates, and performs whatever part of
- its purpose remains meaningful.
-
- (For example, a function in a library to compute square roots has
- a purpose that is entirely well-defined independent of the
- application. Therefore, Subsection 2d requires that any
- application-supplied function or table used by this function must
- be optional: if the application does not supply it, the square
- root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library. To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License. (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.) Do not make any other change in
-these notices.
-
- Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
- This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
- 4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
- If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
- 5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library". Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
- However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library". The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
- When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library. The
-threshold for this to be true is not precisely defined by law.
-
- If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work. (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
- Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
- 6. As an exception to the Sections above, you may also compile or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
- You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License. You must supply a copy of this License. If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License. Also, you must do one
-of these things:
-
- a) Accompany the work with the complete corresponding
- machine-readable source code for the Library including whatever
- changes were used in the work (which must be distributed under
- Sections 1 and 2 above); and, if the work is an executable linked
- with the Library, with the complete machine-readable "work that
- uses the Library", as object code and/or source code, so that the
- user can modify the Library and then relink to produce a modified
- executable containing the modified Library. (It is understood
- that the user who changes the contents of definitions files in the
- Library will not necessarily be able to recompile the application
- to use the modified definitions.)
-
- b) Accompany the work with a written offer, valid for at
- least three years, to give the same user the materials
- specified in Subsection 6a, above, for a charge no more
- than the cost of performing this distribution.
-
- c) If distribution of the work is made by offering access to copy
- from a designated place, offer equivalent access to copy the above
- specified materials from the same place.
-
- d) Verify that the user has already received a copy of these
- materials or that you have already sent this user a copy.
-
- For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it. However, as a special exception,
-the source code distributed need not include anything that is normally
-distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
- It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system. Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
- 7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
- a) Accompany the combined library with a copy of the same work
- based on the Library, uncombined with any other library
- facilities. This must be distributed under the terms of the
- Sections above.
-
- b) Give prominent notice with the combined library of the fact
- that part of it is a work based on the Library, and explaining
- where to find the accompanying uncombined form of the same work.
-
- 8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License. Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License. However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
- 9. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Library or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
- 10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
- 11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all. For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply,
-and the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
- 12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License may add
-an explicit geographical distribution limitation excluding those countries,
-so that distribution is permitted only in or among countries not thus
-excluded. In such case, this License incorporates the limitation as if
-written in the body of this License.
-
- 13. The Free Software Foundation may publish revised and/or new
-versions of the Library General Public License from time to time.
-Such new versions will be similar in spirit to the present version,
-but may differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation. If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-
- 14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-write to the author to ask for permission. For software which is
-copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this. Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
- NO WARRANTY
-
- 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
- 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.
-
- END OF TERMS AND CONDITIONS
-
- Appendix: How to Apply These Terms to Your New Libraries
-
- If you develop a new library, and you want it to be of the greatest
-possible use to the public, we recommend making it free software that
-everyone can redistribute and change. You can do so by permitting
-redistribution under these terms (or, alternatively, under the terms of the
-ordinary General Public License).
-
- To apply these terms, attach the following notices to the library. It is
-safest to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least the
-"copyright" line and a pointer to where the full notice is found.
-
- <one line to give the library's name and a brief idea of what it does.>
- Copyright (C) <year> <name of author>
-
- This library is free software; you can redistribute it and/or
- modify it under the terms of the GNU Library General Public
- License as published by the Free Software Foundation; either
- version 2 of the License, or (at your option) any later version.
-
- This library is distributed in the hope that it will be useful,
- but WITHOUT ANY WARRANTY; without even the implied warranty of
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
- Library General Public License for more details.
-
- You should have received a copy of the GNU Library General Public
- License along with this library; if not, write to the Free
- Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
-
-Also add information on how to contact you by electronic and paper mail.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the library, if
-necessary. Here is a sample; alter the names:
-
- Yoyodyne, Inc., hereby disclaims all copyright interest in the
- library `Frob' (a library for tweaking knobs) written by James Random Hacker.
-
- <signature of Ty Coon>, 1 April 1990
- Ty Coon, President of Vice
-
-That's all there is to it!

-
- 3.6 AGP Memory Access
-
- On "PC" computers, AGP memory can be allocated with glXAllocateMemoryNV
- and freed with glXFreeMemoryNV. Sometimes it's useful to know where a
- block of AGP memory is located with respect to the start of the AGP
- aperature. The function
-
- GLuint glXGetAGPOffsetMESA( const GLvoid *pointer )
-
- Returns the offset of the given memory block from the start of AGP
- memory in basic machine units (i.e. bytes). If pointer is invalid
- the value ~0 will be returned.
-
-GLX Protocol
-
- None. This is a client side-only extension.
-
-Errors
-
- glXGetAGPOffsetMESA will return ~0 if the pointer does not point to
- an AGP memory region.

-
- The function

-
- may be used to copy a rectangular region of the back color buffer to
- the front color buffer. This can be used to quickly repaint 3D windows
- in response to expose events when the back color buffer cannot be
- damaged by other windows.
-
- <x> and <y> indicates the lower-left corner of the region to copy and
- <width> and <height> indicate the size in pixels. Coordinate (0,0)
- corresponds to the lower-left pixel of the window, like glReadPixels.
-
- If dpy and drawable are the display and drawable for the calling
- thread's current context, glXCopySubBufferMESA performs an
- implicit glFlush before it returns. Subsequent OpenGL commands
- may be issued immediately after calling glXCopySubBufferMESA, but
- are not executed until the copy is completed.
-
-GLX Protocol
-
- None at this time. The extension is implemented in terms of ordinary
- Xlib protocol inside of Mesa.

-Errors
-
- None.

- EGL Extension #not assigned
-
-Dependencies
-
- Reguires EGL 1.4 or later. This extension is written against the
- wording of the EGL 1.4 specification.
-
- EGL_KHR_base_image is required.
-
-Overview
-
- This extension provides entry points for integrating EGLImage with the
- Linux DRM mode setting and memory management drivers. The extension
- lets applications create EGLImages without a client API resource and
- lets the application get the DRM buffer handles.
-
-IP Status
-
- Open-source; freely implementable.
-
-New Procedures and Functions
-
- EGLImageKHR eglCreateDRMImageMESA(EGLDisplay dpy,
- const EGLint *attrib_list);
-
- EGLBoolean eglExportDRMImageMESA(EGLDisplay dpy,
- EGLImageKHR image,
- EGLint *name,
- EGLint *handle,
- EGLint *stride);
-
-New Tokens
-
- Accepted in the <attrib_list> parameter of eglCreateDRMImageMESA:
-
- EGL_DRM_BUFFER_FORMAT_MESA 0x31D0
- EGL_DRM_BUFFER_USE_MESA 0x31D1
-
- Accepted as values for the EGL_IMAGE_FORMAT_MESA attribute:
-
- EGL_DRM_BUFFER_FORMAT_ARGB32_MESA 0x31D2
-
- Bits accepted in EGL_DRM_BUFFER_USE_MESA:
-
- EGL_DRM_BUFFER_USE_SCANOUT_MESA 0x0001
- EGL_DRM_BUFFER_USE_SHARE_MESA 0x0002
-
- Accepted in the <target> parameter of eglCreateImageKHR:
-
- EGL_DRM_BUFFER_MESA 0x31D3
-
- Use when importing drm buffer:
-
- EGL_DRM_BUFFER_STRIDE_MESA 0x31D4
- EGL_DRM_BUFFER_FORMAT_MESA 0x31D0
-
-Additions to the EGL 1.4 Specification:
-
- To create a DRM EGLImage, call
-
- EGLImageKHR eglCreateDRMImageMESA(EGLDisplay dpy,
- const EGLint *attrib_list);
-
- In the attribute list, pass EGL_WIDTH, EGL_HEIGHT and format and
- use in the attrib list using EGL_DRM_BUFFER_FORMAT_MESA and
- EGL_DRM_BUFFER_USE_MESA. The only format specified by this
- extension is EGL_DRM_BUFFER_FORMAT_ARGB32_MESA, where each pixel
- is a CPU-endian, 32-bit quantity, with alpha in the upper 8 bits,
- then red, then green, then blue. The bit values accepted by
- EGL_DRM_BUFFER_USE_MESA are EGL_DRM_BUFFER_USE_SCANOUT_MESA and
- EGL_DRM_BUFFER_USE_SHARE_MESA. EGL_DRM_BUFFER_USE_SCANOUT_MESA
- requests that the created EGLImage should be usable as a scanout
- buffer with the DRM kernel modesetting API. The
- EGL_DRM_BUFFER_USE_SHARE_MESA bit requests that the EGLImage can
- be shared with other processes by passing the underlying DRM
- buffer name.
-
- To create a process local handle or a global DRM name for a
- buffer, call
-
- EGLBoolean eglExportDRMImageMESA(EGLDisplay dpy,
- EGLImageKHR image,
- EGLint *name,
- EGLint *handle,
- EGLint *stride);
-
- If <name> is non-NULL, a global name is assigned to the image and
- written to <name>, the handle (local to the DRM file descriptor,
- for use with DRM kernel modesetting API) is written to <handle> if
- non-NULL and the stride (in bytes) is written to <stride>, if
- non-NULL.
-
- Import a shared buffer by calling eglCreateImageKHR with
- EGL_DRM_BUFFER_MESA as the target, using EGL_WIDTH, EGL_HEIGHT,
- EGL_DRM_BUFFER_FORMAT_MESA, EGL_DRM_BUFFER_STRIDE_MESA
- in the attrib list.
-
-Issues
-
- 1. Why don't we use eglCreateImageKHR with a target that
- indicates that we want to create an EGLImage from scratch?
-
- RESOLVED: The eglCreateImageKHR entry point is reserved for
- creating an EGLImage from an already existing client API
- resource. This is fine when we're creating the EGLImage from
- an existing DRM buffer name, it doesn't seem right to overload
- the function to also allocate the underlying resource.
-
- 2. Why don't we use an eglQueryImageMESA type functions for
- querying the DRM EGLImage attributes (name, handle, and stride)?
-
- RESOLVED: The eglQueryImage function has been proposed often,
- but it goes against the EGLImage design. EGLImages are opaque
- handles to a 2D array of pixels, which can be passed between
- client APIs. By referenceing an EGLImage in a client API, the
- EGLImage target (a texture, a renderbuffer or such) can be
- used to query the attributes of the EGLImage. We don't have a
- full client API for creating and querying DRM buffers, though,
- so we use a new EGL extension entry point instead.
-

- Version 1, June 3, 2010
- Initial draft (Kristian Høgsberg)
- Version 2, August 25, 2010
- Flesh out the extension a bit, add final EGL tokens, capture

- OpenGL 1.0 or later is required
- This extensions is written against the OpenGL 1.4 Specification.
-
-Overview
-
- This extension adds a new pixel storage parameter to indicate that
- images are to be packed in top-to-bottom order instead of OpenGL's
- conventional bottom-to-top order. Only pixel packing can be
- inverted (i.e. for glReadPixels, glGetTexImage, glGetConvolutionFilter,
- etc).
-
- Almost all known image file formats store images in top-to-bottom
- order. As it is, OpenGL reads images from the frame buffer in
- bottom-to-top order. Thus, images usually have to be inverted before
- writing them to a file with image I/O libraries. This extension
- allows images to be read such that inverting isn't needed.
-
-IP Status
-
- None
-
-Issues
-
- 1. Should we also defined UNPACK_INVERT_MESA for glDrawPixels, etc?
-
- Resolved: No, we're only concerned with pixel packing. There are other
- solutions for inverting images when using glDrawPixels (negative Y pixel
- zoom) or glTexImage (invert the vertex T coordinates). It would be easy
- enough to define a complementary extension for pixel packing in the
- future if needed.

-Overview
-
- Since Mesa allows RGB rendering into drawables with PseudoColor,
- StaticColor, GrayScale and StaticGray visuals, Mesa needs a colormap
- in order to compute pixel values during rendering.
-
- The colormap associated with a window can be queried with normal
- Xlib functions but there is no colormap associated with pixmaps.
-
- The glXCreateGLXPixmapMESA function is an alternative to glXCreateGLXPixmap
- which allows specification of a colormap.

-
- The Mesa implementation of GLX allows RGB rendering into X windows and
- pixmaps of any visual class, not just TrueColor or DirectColor. In order
- to compute pixel values from RGB values Mesa requires a colormap.
-
- The function
-
- GLXPixmap glXCreateGLXPixmapMESA( Display *dpy, XVisualInfo *visual,
- Pixmap pixmap, Colormap cmap );
-
- allows one to create a GLXPixmap with a specific colormap. The image
- rendered into the pixmap may then be copied to a window (which uses the
- same colormap and visual) with the expected results.

- Mesa 2.2 or later is required.
-
-Overview
-
- Mesa is often used as a client library with no integration with
- the computer's window system (an X server, for example). And since
- Mesa does not have an event loop nor window system callbacks, it
- cannot properly respond to window system events. In particular,
- Mesa cannot automatically detect when a window has been resized.
-
- Mesa's glViewport command queries the current window size and updates
- its internal data structors accordingly. This normally works fine
- since most applications call glViewport in responce to window size
- changes.
-
- In some situations, however, the application may not call glViewport
- when a window size changes but would still like Mesa to adjust to
- the new window size. This extension exports a new function to solve
- this problem.

- reallocating depth, stencil, alpha and accumulation buffers.

-
- Add a new section 8.10 "Debug Functions":
-
- Debug functions are available to both fragment and vertex shaders.
- They are used to track the execution of a shader by logging
- passed-in arguments to the debug object's log. Those values can be
- retrieved by the application for inspection after shader execution
- is complete.
-
- The text, if any, produced by any of these functions is appended
- to each debug object that is attached to the program object.
- There are different debug log types
-
- Add a new section 8.10.1 "Print Function":
-
- The following printMESA prototypes are available.
-
- void printMESA(const float value)
- void printMESA(const int value)
- void printMESA(const bool value)
- void printMESA(const vec2 value)
- void printMESA(const vec3 value)
- void printMESA(const vec4 value)
- void printMESA(const ivec2 value)
- void printMESA(const ivec3 value)
- void printMESA(const ivec4 value)
- void printMESA(const bvec2 value)
- void printMESA(const bvec3 value)
- void printMESA(const bvec4 value)
- void printMESA(const mat2 value)
- void printMESA(const mat3 value)
- void printMESA(const mat4 value)
- void printMESA(const sampler1D value)
- void printMESA(const sampler2D value)
- void printMESA(const sampler3D value)
- void printMESA(const samplerCube value)
- void printMESA(const sampler1DShadow value)
- void printMESA(const sampler2DShadow value)
-
- The printMESA function writes the argument <value> to the "debug
- print log" (XXX DEBUG_PRINT_MESA?). Each component is written in
- text format (XXX format!) and is delimited by a white space (XXX 1
- or more?).
-
- Add a new section 8.10.2 "Assert Function":
-
- The following assertMESA prototypes are available.
-
- void assertMESA(const bool condition)
- void assertMESA(const bool condition, const int cookie)
- void assertMESA(const bool condition, const int cookie,
- const int file, const int line)
-
- The assertMESA function checks if the argument <condition> is
- true or false. If it is true, nothing happens. If it is false,
- a diagnostic message is written to the "debug assert log".
- The message contains the argument <file>, <line>, <cookie> and
- implementation dependent double-quoted string, each of this
- delimited by a white space. If the argument <cookie> is not present,
- it is meant as if it was of value 0. If the arguments <file> and
- <line> are not present, they are meant as if they were of values
- __FILE__ and __LINE__, respectively. The following three calls
- produce the same output, assuming they were issued from the same
- file and line.
-
- assertMESA (false);
- assertMESA (false, 0);
- assertMESA (false, 0, __FILE__, __LINE__);
-
- The diagnostic message examples follow.
-
- 1 89 0 ""
- 1 45 333 "all (lessThanEqual (fragColor, vec4 (1.0)))"
- 1 66 1 "assertion failed in file 1, line 66, cookie 1"

- [Add the following to Section 3.3.10 of the GLX Specification (Double
- Buffering)]
-
- glXSwapIntervalMESA specifies the minimum number of video frame periods
- per buffer swap. (e.g. a value of two means that the color buffers
- will be swapped at most every other video frame.) A return value
- of zero indicates success; otherwise an error occurred. The interval
- takes effect when glXSwapBuffers is first called subsequent to the
- glXSwapIntervalMESA call.
-
- A video frame period is the time required by the monitor to display a
- full frame of video data. In the case of an interlaced monitor,
- this is typically the time required to display both the even and odd
- fields of a frame of video data.
-
- If <interval> is set to a value of 0, buffer swaps are not synchron-
- ized to a video frame. The <interval> value is silently clamped to
- the maximum implementation-dependent value supported before being
- stored.
-
- The swap interval is not part of the render context state. It cannot
- be pushed or popped. The current swap interval for the window
- associated with the current context can be obtained by calling
- glXGetSwapIntervalMESA. The default swap interval is 0.
-
- On XFree86, setting the environment variable LIBGL_THROTTLE_REFRESH sets
- the swap interval to 1.
-
-Errors
-
- glXSwapIntervalMESA returns GLX_BAD_CONTEXT if there is no current
- GLXContext or if the current context is not a direct rendering context.

- call to enable the statistic) to when the next buffer swap completes, tf
- is the entire time for a frame which may be multiple screen refreshes
- depending on the swap interval as set by the GLX_SGI_swap_control or
- GLX_OML_sync_control extensions.
-
- The value, percent, indicates the amount of time spent between the
- completion of the two swaps. If the value is in the range [0,1], the
- buffer swap occurred within the time period required to maintain a
- constant frame rate. If the value is in the range (1,max], a constant
- frame rate was not achieved. The value indicates the number of frames
- required to draw.
-
- This definition of "percent" differs slightly from
- WGL_I3D_swap_frame_usage. In WGL_I3D_swap_frame_usage, the measurement
- is taken from the completion of one swap to the issuance of the next.
- This representation may not be as useful as measuring between
- completions, as a significant amount of time may pass between the
- issuance of a swap and the swap actually occurring.
-
- There is also a mechanism to determine whether a frame swap was
- missed.

- The frame usage is measured as the percentage of the swap period elapsed
- between two buffer-swap operations being committed. In unextended GLX the
- swap period is the vertical refresh time. If SGI_swap_control or
- MESA_swap_control are supported, the swap period is the vertical refresh
- time multiplied by the swap interval (or one if the swap interval is set
- to zero).
-
- If OML_sync_control is supported, the swap period is the vertical
- refresh time multiplied by the divisor parameter to
- glXSwapBuffersMscOML. The frame usage in this case is less than 1.0 if
- the swap is committed before target_msc, and is greater than or equal to
- 1.0 otherwise. The actual usage value is based on the divisor and is
- never less than 0.0.
-

-
- Missed frame swaps can be tracked by calling the following function:
-
- int glXBeginFrameTrackingMESA(Display *dpy,

-
- glXBeginFrameTrackingMESA resets a "missed frame" count and
- synchronizes with the next frame vertical sync before it returns.
- If a swap is missed based in the rate control specified by the
- <interval> set by glXSwapIntervalSGI or the default swap of once
- per frame, the missed frame count is incremented.
-
- The current missed frame count and total number of swaps since
- the last call to glXBeginFrameTrackingMESA can be obtained by
- calling the following function:
-
- int glXQueryFrameTrackingMESA(Display *dpy,
- GLXDrawable drawable,
- int64_t *swapCount,
- int64_t *missedFrames,
- float *lastMissedUsage)
-
- The location pointed to by <swapCount> will be updated with the
- number of swaps that have been committed. This value may not match the
- number of swaps that have been requested since swaps may be
- queued by the implementation. This function can be called at any
- time and does not synchronize to vertical blank.
-
- The location pointed to by <missedFrames> will contain the number
- swaps that missed the specified frame. The frame usage for the
- last missed frame is returned in the location pointed to by
- <lastMissedUsage>.
-
- Frame tracking is disabled by calling the function
-
- int glXEndFrameTrackingMESA(Display *dpy,

-
- This function will not return until all swaps have occurred. The

-
-Overview
-
- There are a number of circumstances where an application may wish to
- blend two textures out of a larger set of textures. Moreover, in some
- cases the selected textures may vary on a per-fragment basis within
- a polygon. Several examples include:
-
- 1. High dynamic range textures. The application stores several
- different "exposures" of an image as different textures. On a
- per-fragment basis, the application selects which exposures are
- used.
-
- 2. A terrain engine where the altitude of a point determines the
- texture applied to it. If the transition is from beach sand to
- grass to rocks to snow, the application will store each texture
- in a different texture map, and dynamically select which two
- textures to blend at run-time.
-
- 3. Storing short video clips in textures. Each depth slice is a
- single frame of video.
-
- Several solutions to this problem have been proposed, but they either
- involve using a separate texture unit for each texture map or using 3D
- textures without mipmaps. Both of these options have major drawbacks.
-
- This extension provides a third alternative that eliminates the major
- drawbacks of both previous methods. A new texture target,
- TEXTURE_2D_ARRAY, is added that functions identically to TEXTURE_3D in
- all aspects except the sizes of the non-base level images. In
- traditional 3D texturing, the size of the N+1 LOD is half the size
- of the N LOD in all three dimensions. For the TEXTURE_2D_ARRAY target,
- the height and width of the N+1 LOD is halved, but the depth is the
- same for all levels of detail. The texture then becomes an array of
- 2D textures. The per-fragment texel is selected by the R texture
- coordinate.

-
- Change the first paragraph (page 150) to say (spec changes identical to

- "The command
-
- void TexImage3D(enum target, int level, int internalformat,
- sizei width, sizei height, sizei depth, int border,
- enum format, enum type, void *data);
-
- is used to specify a three-dimensional texture image. target must be one
- one of TEXTURE_3D for a three-dimensional texture or

- Additionally, target may be either PROXY_TEXTURE_3D for a
- three-dimensional proxy texture, or PROXY_TEXTURE_2D_ARRAY_EXT for a
- two-dimensional proxy array texture."
-
- Change the fourth paragraph on page 151 to say (spec changes identical
- to EXT_texture_array):
-
- "Textures with a base internal format of DEPTH_COMPONENT are supported
- by texture image specification commands only if target is TEXTURE_1D,
- TEXTURE_2D, TEXTURE_1D_ARRAY_EXT, TEXTURE_2D_ARRAY_EXT,
- PROXY_TEXTURE_1D, PROXY_TEXTURE_2D, PROXY_TEXTURE_1D_ARRAY_EXT, or
- PROXY_TEXTURE_2D_ARRAY_EXT. Using this format in conjunction with any
- other target will result in an INVALID_OPERATION error."
-
-
- Change the fourth paragraph on page 156 to say (spec changes identical
- to EXT_texture_array):
-
- "The command
-
- void TexImage2D(enum target, int level,
- int internalformat, sizei width, sizei height,
- int border, enum format, enum type, void *data);
-
- is used to specify a two-dimensional texture image. target must be one
- of TEXTURE_2D for a two-dimensional texture, TEXTURE_1D_ARRAY_EXT for a

- texture, PROXY_TEXTURE_1D_ARRAY_EXT for a one-dimensional proxy array
- texture, or PROXY TEXTURE_CUBE_MAP for a cube map proxy texture in the
- special case discussed in section 3.8.11. The other parameters match
- the corresponding parameters of TexImage3D.
-
- For the purposes of decoding the texture image, TexImage2D is
- equivalent to calling TexImage3D with corresponding arguments and depth
- of 1, except that
-
- * The border depth, d_b, is zero, and the depth of the image is
- always 1 regardless of the value of border.
-
- * The border height, h_b, is zero if <target> is
- TEXTURE_1D_ARRAY_EXT, and <border> otherwise.
-

-
- After the first paragraph (page 175) add:
-
- "For one-dimensional array textures, h_b and d_b are treated as 1,

-
- -- Section 3.8.11 "Texture State and Proxy State"
-
- Change the second and third paragraphs (page 179) to say (spec changes
- identical to EXT_texture_array):
-
- "In addition to image arrays for one-, two-, and three-dimensional
- textures, one- and two-dimensional array textures, and the six image
- arrays for the cube map texture, partially instantiated image arrays
- are maintained for one-, two-, and three-dimensional textures and one-
- and two-dimensional array textures. Additionally, a single proxy image
- array is maintained for the cube map texture. Each proxy image array
- includes width, height, depth, border width, and internal format state
- values, as well as state for the red, green, blue, alpha, luminance,
- and intensity component resolutions. Proxy image arrays do not include
- image data, nor do they include texture properties. When TexImage3D is
- executed with target specified as PROXY_TEXTURE_3D, the
- three-dimensional proxy state values of the specified level-of-detail
- are recomputed and updated. If the image array would not be supported
- by TexImage3D called with target set to TEXTURE 3D, no error is
- generated, but the proxy width, height, depth, border width, and
- component resolutions are set to zero. If the image array would be
- supported by such a call to TexImage3D, the proxy state values are set
- exactly as though the actual image array were being specified. No pixel
- data are transferred or processed in either case.
-
- Proxy arrays for one- and two-dimensional textures and one- and
- two-dimensional array textures are operated on in the same way when
- TexImage1D is executed with target specified as PROXY_TEXTURE_1D,
- TexImage2D is executed with target specified as PROXY_TEXTURE_2D or
- PROXY_TEXTURE_1D_ARRAY_EXT, or TexImage3D is executed with target
- specified as PROXY_TETXURE_2D_ARRAY_EXT."
-
- -- Section 3.8.12 "Texture Objects"
-
- Change section (page 180) to say (spec changes identical to
- EXT_texture_array):
-
- "In addition to the default textures TEXTURE_1D, TEXTURE_2D,
- TEXTURE_3D, TEXTURE_CUBE_MAP, TEXTURE_1D_ARRAY_EXT, and TEXTURE_2D_EXT,
- named one-, two-, and three-dimensional, cube map, and one- and
- two-dimensional array texture objects can be created and operated upon.
- The name space for texture objects is the unsigned integers, with zero
- reserved by the GL.
-
- A texture object is created by binding an unused name to TEXTURE_1D,
- TEXTURE_2D, TEXTURE_3D, TEXTURE_CUBE_MAP, TEXTURE_1D_ARRAY_EXT, or
- TEXTURE_2D_ARRAY_EXT. The binding is effected by calling
-
- void BindTexture(enum target, uint texture);
-
- with <target> set to the desired texture target and <texture> set to
- the unused name. The resulting texture object is a new state vector,
- comprising all the state values listed in section 3.8.11, set to the
- same initial values. If the new texture object is bound to TEXTURE_1D,
- TEXTURE_2D, TEXTURE_3D, TEXTURE_CUBE_MAP, TEXTURE_1D_ARRAY_EXT, or
- TEXTURE_2D_ARRAY_EXT, it is and remains a one-, two-,
- three-dimensional, cube map, one- or two-dimensional array texture
- respectively until it is deleted.
-
- BindTexture may also be used to bind an existing texture object to
- either TEXTURE_1D, TEXTURE_2D, TEXTURE_3D, TEXTURE_CUBE_MAP,
- TEXTURE_1D_ARRAY_EXT, or TEXTURE_2D_ARRAY_EXT. The error
- INVALID_OPERATION is generated if an attempt is made to bind a texture
- object of different dimensionality than the specified target. If the
- bind is successful no change is made to the state of the bound texture
- object, and any previous binding to target is broken.
-
- While a texture object is bound, GL operations on the target to which
- it is bound affect the bound object, and queries of the target to which
- it is bound return state from the bound object. If texture mapping of
- the dimensionality of the target to which a texture object is bound is
- enabled, the state of the bound texture object directs the texturing
- operation.
-
- In the initial state, TEXTURE_1D, TEXTURE_2D, TEXTURE_3D,
- TEXTURE_CUBE_MAP, TEXTURE_1D_ARRAY_EXT, and TEXTURE_2D_ARRAY_EXT have
- one-, two-, three-dimensional, cube map, and one- and two-dimensional
- array texture state vectors respectively associated with them. In order
- that access to these initial textures not be lost, they are treated as
- texture objects all of whose names are 0. The initial one-, two-,
- three-dimensional, cube map, one- and two-dimensional array textures
- are therefore operated upon, queried, and applied as TEXTURE_1D,
- TEXTURE_2D, TEXTURE_3D, TEXTURE_CUBE_MAP, TEXTURE_1D_ARRAY_EXT, and
- TEXTURE_2D_ARRAY_EXT respectively while 0 is bound to the corresponding
- targets.
-
- Change second paragraph on page 181 to say (spec changes identical to
- EXT_texture_array):
-
- "... If a texture that is currently bound to one of the targets
- TEXTURE_1D, TEXTURE_2D, TEXTURE_3D, TEXTURE_CUBE_MAP,
- TEXTURE_1D_ARRAY_EXT, or TEXTURE_2D_ARRAY_EXT is deleted, it is as
- though BindTexture had been executed with the same target and texture
- zero. ..."
-
- Change second paragraph on page 182 to say (spec changes identical to
- EXT_texture_array):
-
- "The texture object name space, including the initial one-, two-, and
- three dimensional, cube map, and one- and two-dimensional array texture
- objects, is shared among all texture units. ..."
-
-
- -- Section 3.8.14 "Depth Texture Comparison Modes" in "Texture Comparison Modes"
-
- Change second through fourth paragraphs (page 188) to say:
-
- "Let D_t be the depth texture value, in the range [0, 1]. For
- texture lookups from one- and two-dimesional, rectangle, and
- one-dimensional array targets, let R be the interpolated <r>
- texture coordinate, clamped to the range [0, 1]. For texture lookups
- from two-dimesional array texture targets, let R be the interpolated
- <q> texture coordinate, clamped to the range [0, 1]. Then the
- effective texture value L_t, I_t, or A_t is computed as follows:
-
- If the value of TEXTURE_COMPARE_MODE is NONE, then
-
- r = Dt
-
- If the value of TEXTURE_COMPARE_MODE is
- COMPARE_REF_DEPTH_TO_TEXTURE_EXT), then r depends on the texture

-
- -- Section 3.8.15 "Texture Application"
-
- Change the first paragraph (page 189) to say:
-
- "Texturing is enabled or disabled using the generic Enable and Disable

- For array textures, images are not arranged in 4x4x4 or 4x4x2 blocks as in

-
- S3TC compression is not supported for one-dimensional texture targets in

- This extension allows the use of the four S3TC internal format types in
- TexImage3D, CompressedTexImage3D, and CompressedTexSubImage3D calls.

-Issues
-
- (1) Is "texture stack" a good name for this functionality?
-
- NO. The name is changed to "array texture" to match the
- nomenclature used by GL_EXT_texture_array.
-
- (2) Should the R texture coordinate be treated as normalized or
- un-normalized? If it were un-normalized, floor(R) could be thought
- of as a direct index into the array texture. This may be more
- convenient for applications.
-
- RESOLVED. All texture coordinates are normalized. The issue of
- un-normalized texture coordinates has been discussed in the ARB
- before and should be left for a layered extension.
-
- RE-RESOLVED. The R coordinate is un-normalized. Accessing an array
- using [0, layers-1] coordinates is much more natural.
-
- (3) How does LOD selection work for stacked textures?
-
- RESOLVED. For 2D array textures the R coordinate is ignored, and
- the LOD selection equations for 2D textures are used. For 1D
- array textures the T coordinate is ignored, and the LOD selection
- equations for 1D textures are used. The expected usage is in a
- fragment program with an explicit LOD selection.
-
- (4) What is the maximum size of a 2D array texture? Is it the same
- as for a 3D texture, or should a new query be added? How about for 1D
- array textures?
-
- RESOLVED. A new query is added.
-
- (5) How are array textures exposed in GLSL?
-
- RESOLVED. Use GL_EXT_texture_array.
-
- (6) Should a 1D array texture also be exposed?
-
- RESOLVED. For orthogonality, yes.
-
- (7) How are stacked textures attached to framebuffer objects?
-
- RESOLVED. Layers of both one- and two-dimensional array textures
- are attached using FreambufferTextureLayerEXT. Once attached, the
- array texture layer behaves exactly as either a one- or
- two-dimensional texture.
-
- (8) How is this extension related to GL_EXT_texture_array?
-
- This extension adapats GL_MESAX_texture_stack to the notation,
- indexing, and FBO access of GL_EXT_texture_array. This extension
- replaces the GLSL support of GL_EXT_texture_array with
- GL_ARB_fragment_program support.
-
- Assembly program support is also provided by GL_NV_gpu_program4.
- GL_NV_gpu_program4 also adds support for other features that are
- specific to Nvidia hardware, while this extension adds only support
- for array textures.
-
- Much of text of this extension that has changed since
- GL_MESAX_texture_stack comes directly from either
- GL_EXT_texture_array or GL_NV_gpu_program4.

-
- Written based on the wording of the OpenGL 2.0 specification.
-
- This extension trivially interacts with ARB_texture_float.
- This extension shares some language with ARB_texture_compression_rgtc
- but does not depend on it.
-
-Overview
-
- OpenGL prior to 3.1 does not support any signed texture formats.
- ARB_texture_compression_rgtc introduces some compressed red and
- red_green signed formats but no uncompressed ones, which might
- still be useful. NV_texture_shader adds signed texture formats,
- but also a lot of functionality which has been superceded by fragment
- shaders.
- It is usually possible to get the same functionality
- using a unsigned format by doing scale and bias in a shader, but this
- is undesirable since modern hardware has direct support for this.
- This extension adds a signed 4-channel texture format by backporting
- the relevant features from OpenGL 3.1, as a means to support this in
- OpenGL implementations only supporting older versions.
-
-Issues
-
- 1) What should this extension be called?
-
- RESOLVED: MESA_texture_signed_rgba seems reasonable.
- The rgba part is there because only 4 channel format is supported.
-
-
- 2) Should the full set of signed formats (alpha, luminance, rgb, etc.)
- be supported?
-
- RESOLVED: NO. To keep this extension simple, only add the most
- universal format, rgba. alpha/luminance can't be trivially supported
- since OpenGL 3.1 does not support them any longer, and there is some
- implied dependency on ARB_texture_rg for red/red_green formats so
- avoid all this. Likewise, only 8 bits per channel is supported.
-
-
- 3) Should this extension use new enums for the texture formats?
-
- RESOLVED: NO. Same enums as those used in OpenGL 3.1.
-
-
- 4) How are signed integer values mapped to floating-point values?
-
- RESOLVED: Same as described in issue 5) of
- ARB_texture_compression_rgtc (quote):
- A signed 8-bit two's complement value X is computed to
- a floating-point value Xf with the formula:
-
- { X / 127.0, X > -128
- Xf = {
- { -1.0, X == -128
-
- This conversion means -1, 0, and +1 are all exactly representable,
- however -128 and -127 both map to -1.0. Mapping -128 to -1.0
- avoids the numerical awkwardness of have a representable value
- slightly more negative than -1.0.
-
- This conversion is intentionally NOT the "byte" conversion listed
- in Table 2.9 for component conversions. That conversion says:
-
- Xf = (2*X + 1) / 255.0
-
- The Table 2.9 conversion is incapable of exactly representing
- zero.
-
- (Difference to ARB_texture_compression_rgtc):
- This is the same mapping as OpenGL 3.1 uses.
- This is also different to what NV_texture_shader used.
- The above mapping should be considered the reference, but there
- is some leeway so other mappings are allowed for implementations which
- cannot do this. Particulary the mapping given in NV_texture_shader or
- the standard OpenGL byte/float mapping is considered acceptable too, as
- might be a mapping which represents -1.0 by -128, 0.0 by 0 and 1.0 by
- 127 (that is, uses different scale factors for negative and positive
- numbers).
- Also, it is ok to store incoming GL_BYTE user data as-is, without
- converting to GL_FLOAT (using the standard OpenGL float/byte mapping)
- and converting back (using the mapping described here).
- Other than those subtle issues there are no other non-standard
- conversions used, so when using for instance CopyTexImage2D with
- a framebuffer clamped to [0,1] all converted numbers will be in the range
- [0, 127] (and not scaled and biased).
-
-
- 5) How will signed components resulting from RGBA8_SNORM texture
- fetches interact with fragment coloring?
-
- RESOLVED: Same as described in issue 6) of
- ARB_texture_compression_rgtc (quote):
- The specification language for this extension is silent
- about clamping behavior leaving this to the core specification
- and other extensions. The clamping or lack of clamping is left
- to the core specification and other extensions.
-
- For assembly program extensions supporting texture fetches
- (ARB_fragment_program, NV_fragment_program, NV_vertex_program3,
- etc.) or the OpenGL Shading Language, these signed formats will
- appear as expected with unclamped signed components as a result
- of a texture fetch instruction.
-
- If ARB_color_buffer_float is supported, its clamping controls
- will apply.
-
- NV_texture_shader extension, if supported, adds support for
- fixed-point textures with signed components and relaxed the
- fixed-function texture environment clamping appropriately. If the
- NV_texture_shader extension is supported, its specified behavior
- for the texture environment applies where intermediate values
- are clamped to [-1,1] unless stated otherwise as in the case
- of explicitly clamped to [0,1] for GL_COMBINE. or clamping the
- linear interpolation weight to [0,1] for GL_DECAL and GL_BLEND.
-
- Otherwise, the conventional core texture environment clamps
- incoming, intermediate, and output color components to [0,1].
-
- This implies that the conventional texture environment
- functionality of unextended OpenGL 1.5 or OpenGL 2.0 without
- using GLSL (and with none of the extensions referred to above)
- is unable to make proper use of the signed texture formats added
- by this extension because the conventional texture environment
- requires texture source colors to be clamped to [0,1]. Texture
- filtering of these signed formats would be still signed, but
- negative values generated post-filtering would be clamped to
- zero by the core texture environment functionality. The
- expectation is clearly that this extension would be co-implemented
- with one of the previously referred to extensions or used with
- GLSL for the new signed formats to be useful.
-
-
- 6) Should the RGBA_SNORM tokens also be accepted by CopyTexImage
- functions?
-
- RESOLVED: YES.
-
-
- 7) What to do with GetTexParameter if ARB_texture_float is supported,
- in particular what datatype should this return for TEXTURE_RED_TYPE_ARB,
- TEXTURE_GREEN_TYPE_ARB, TEXTURE_BLUE_TYPE_ARB, TEXTURE_ALPHA_TYPE_ARB?
-
- RESOLVED: ARB_texture_float states type is either NONE,
- UNSIGNED_NORMALIZED_ARB, or FLOAT. This extension adds a new enum,
- SIGNED_NORMALIZED, which will be returned accordingly. This is the
- same behaviour as in OpenGL 3.1.
-
-
-New Tokens
-
-
- Accepted by the <internalformat> parameter of
- TexImage1D, TexImage2D, TexImage3D, CopyTexImage1D, and CopyTexImage2D:

- RGBA_SNORM 0x8F93
- RGBA8_SNORM 0x8F97
-
- Returned by the <params> parameter of GetTexLevelParameter:

- of TEXTURE_RED_TYPE_ARB, TEXTURE_GREEN_TYPE_ARB, TEXTURE_BLUE_TYPE_ARB or
- TEXTURE_ALPHA_TYPE_ARB return SIGNED_NORMALIZED if
- the base internal format is RGBA_SNORM.

- OpenGL 1.0 is required.
- The extension is written against the OpenGL 1.2 Specification
-
-Overview
-
- In order to set the current raster position to a specific window
- coordinate with the RasterPos command, the modelview matrix, projection
- matrix and viewport must be set very carefully. Furthermore, if the
- desired window coordinate is outside of the window's bounds one must
- rely on a subtle side-effect of the Bitmap command in order to circumvent
- frustum clipping.
-
- This extension provides a set of functions to directly set the
- current raster position, bypassing the modelview matrix, the
- projection matrix and the viewport to window mapping. Furthermore,
- clip testing is not performed.
-
- This greatly simplifies the process of setting the current raster
- position to a specific window coordinate prior to calling DrawPixels,
- CopyPixels or Bitmap.

-Additions to Chapter 2 of the OpenGL 1.2 Specification (OpenGL Operation)
-
- - (2.12, p. 41) Insert after third paragraph:
-
- Alternately, the current raster position may be set by one of the
- WindowPosMESA commands:
-
- void WindowPos{234}{sidf}MESA( T coords );
- void WindowPos{234}{sidf}vMESA( T coords );
-
- WindosPos4MESA takes four values indicating x, y, z, and w.
- WindowPos3MESA (or WindowPos2MESA) is analaguos, but sets only
- x, y, and z with w implicitly set to 1 (or only x and y with z
- implicititly set to 0 and w implicitly set to 1).
-
- WindowPosMESA operates like RasterPos except that the current modelview
- matrix, projection matrix and viewport parameters are ignored and the
- clip test operation always passes. The current raster position values
- are directly set to the parameters passed to WindowPosMESA. The current
- color, color index and texture coordinate update the current raster
- position's associated data.
-
-Additions to the AGL/GLX/WGL Specifications
-
- None
-
-GLX Protocol
-
- Not specified at this time. However, a protocol message very similar
- to that of RasterPos is expected.

- OpenGL 1.0 or later is required
- This extensions is written against the OpenGL 1.4 Specification.
- NV_texture_rectangle effects the definition of this extension.
-
-Overview
-
- This extension supports texture images stored in the YCbCr format.
- There is no support for converting YCbCr images to RGB or vice versa
- during pixel transfer. The texture's YCbCr colors are converted to
- RGB during texture sampling, after-which, all the usual per-fragment
- operations take place. Only 2D texture images are supported (not
- glDrawPixels, glReadPixels, etc).
-
- A YCbCr pixel (texel) is a 16-bit unsigned short with two components.
- The first component is luminance (Y). For pixels in even-numbered
- image columns, the second component is Cb. For pixels in odd-numbered
- image columns, the second component is Cr. If one were to convert the
- data to RGB one would need to examine two pixels from columns N and N+1
- (where N is even) to deduce the RGB color.

-Overview
-
- Provides a mechanism for DrawPixels and ReadPixels to efficiently
- transfer depth and stencil image data. Specifically, we defined new
- packed pixel formats and types which pack both stencil and depth
- into one value.
-
-Issues:
-
- 1. Is this the right way to distinguish between 24/8 and 8/24
- pixel formats? Should we instead provide both:
-
- GL_DEPTH_STENCIL_MESA
- GL_STENCIL_DEPTH_MESA
-
- And perhaps just use GL_UNSIGNED_INT, GL_UNSIGNED_SHORT ?
-
- 2. If not, is it correct to use _REV to indicate that stencil
- preceeds depth in the 1_15 and 8_24 formats?
-
- 3. Do we really want the GL_UNSIGNED_SHORT formats?

- OpenGL 1.4 is required
- The extension is written against the OpenGL 1.4 specification.
- ARB_vertex_program or ARB_fragment_program or NV_vertex_program
- or NV_fragment_program is required.
-
-Overview
-
- The extension provides facilities for implementing debuggers for
- vertex and fragment programs.
-
- The concept is that vertex and fragment program debuggers will be
- implemented outside of the GL as a utility package. This extension
- only provides the minimal hooks required to implement a debugger.
-
- There are facilities to do the following:
- 1. Have the GL call a user-specified function prior to executing
- each vertex or fragment instruction.
- 2. Query the current program string's execution position.
- 3. Query the current values of intermediate program values.
-
- The main feature is the ProgramCallbackMESA function. It allows the
- user to register a callback function with the GL. The callback will
- be called prior to executing each vertex or fragment program instruction.
-
- From within the callback, the user may issue Get* commands to
- query current GL state. The GetProgramRegisterfvMESA function allows
- current program values to be queried (such as temporaries, input
- attributes, and result registers).
-
- There are flags for enabling/disabling the program callbacks.
-
- The current execution position (as an offset from the start of the
- program string) can be queried with
- GetIntegerv(GL_FRAGMENT_PROGRAM_POSITION_MESA, &pos) or
- GetIntegerv(GL_VERTEX_PROGRAM_POSITION_MESA, &pos).

-
-Issues
-
- 1. Is this the right model for a debugger?
-
- It seems prudent to minimize the scope of this extension and leave
- it up to the developer (or developer community) to write debuggers
- that layer on top of this extension.
-
- If the debugger were fully implemented within the GL it's not
- clear how terminal and GUI-based interfaces would work, for
- example.
-
- 2. There aren't any other extensions that register callbacks with
- the GL. Isn't there another solution?
-
- If we want to be able to single-step through vertex/fragment
- programs I don't see another way to do it.
-
- 3. How do we prevent the user from doing something crazy in the
- callback function, like trying to call glBegin (leading to
- recursion)?
-
- The rule is that the callback function can only issue glGet*()
- functions and no other GL commands. It could be difficult to
- enforce this, however. Therefore, calling any non-get GL
- command from within the callback will result in undefined
- results.
-
- 4. Is this extension amenable to hardware implementation?
-
- Hopefully, but if not, the GL implementation will have to fall
- back to a software path when debugging. This may be acceptable
- for debugging.
-
- 5. What's the <data> parameter to ProgramCallbackMESA for?
-
- It's a common programming practice to associate a user-supplied
- value with callback functions.
-
- 6. Debuggers often allow one to modify intermediate program values,
- then continue. Does this extension support that?
-
- No.
-

-
- In section 5.4 "Display Lists", page 202, add the following command
- to the list of those that are not compiled into display lists:
-
- ProgramCallbackMESA.
-
-
- Add a new section 5.7 "Callback Functions"
-
- The function
-
- void ProgramCallbackMESA(enum target, programcallbackMESA callback,
- void *data)
-
- registers a user-defined callback function with the GL. <target>
- may be FRAGMENT_PROGRAM_ARB or VERTEX_PROGRAM_ARB. The enabled
- callback functions registered with these targets will be called
- prior to executing each instruction in the current fragment or
- vertex program, respectively. The callbacks are enabled and
- disabled by calling Enable or Disable with <cap>
- FRAGMENT_PROGRAM_ARB or VERTEX_PROGRAM_ARB.
-
- The callback function's signature must match the typedef
-
- typedef void (*programcallbackMESA)(enum target, void *data)
-
- When the callback function is called, <target> will either be
- FRAGMENT_PROGRAM_ARB or VERTEX_PROGRAM_ARB to indicate which
- program is currently executing and <data> will be the value
- specified when ProgramCallbackMESA was called.
-
- From within the callback function, only the following GL commands
- may be called:
-
- GetBooleanv
- GetDoublev
- GetFloatv
- GetIntegerv
- GetProgramLocalParameter
- GetProgramEnvParameter
- GetProgramRegisterfvMESA
- GetProgramivARB
- GetProgramStringARB
- GetError
-
- Calling any other command from within the callback results in
- undefined behaviour.
-
-
-Additions to Chapter 6 of the OpenGL 1.4 Specification (State and
-State Requests)
-
- Add a new section 6.1.3 "Program Value Queries":
-
- The command
-
- void GetProgramRegisterfvMESA(enum target, sizei len,
- const ubyte *registerName,
- float *v)
-
- Is used to query the value of program variables and registers
- during program execution. GetProgramRegisterfvMESA may only be
- called from within a callback function registered with
- ProgramCallbackMESA.
-
- <registerName> and <len> specify the name a variable, input
- attribute, temporary, or result register in the program string.
- The current value of the named variable is returned as four
- values in <v>. If <name> doesn't exist in the program string,
- the error INVALID_OPERATION is generated.
-
-Additions to Appendix A of the OpenGL 1.4 Specification (Invariance)

-
-Dependencies on NV_vertex_program and NV_fragment_program
-
- If NV_vertex_program and/or NV_fragment_program are supported,
- vertex and/or fragment programs defined by those extensions may
- be debugged as well. Register queries will use the syntax used
- by those extensions (i.e. "v[X]" to query vertex attributes,
- "o[X]" for vertex outputs, etc.)
-
-Errors
-
- INVALID_OPERATION is generated if ProgramCallbackMESA is called
- between Begin and End.
-
- INVALID_ENUM is generated by ProgramCallbackMESA if <target> is not
- a supported vertex or fragment program type.
-
- Note: INVALID_OPERAION IS NOT generated by GetProgramRegisterfvMESA,
- GetBooleanv, GetDoublev, GetFloatv, or GetIntegerv if called between
- Begin and End when a vertex or fragment program is currently executing.
-
- INVALID_ENUM is generated by ProgramCallbackMESA,
- GetProgramRegisterfvMESA if <target> is not a program target supported
- by ARB_vertex_program, ARB_fragment_program (or NV_vertex_program or
- NV_fragment_program).
-
- INVALID_VALUE is generated by GetProgramRegisterfvMESA if <registerName>
- does not name a known program register or variable.
-
- INVALID_OPERATION is generated by GetProgramRegisterfvMESA when a
- register query is attempted for a program target that's not currently
- being executed.

- vertex programs.
-
-
- /* This is called by the GL when the vertex program is executing.

- glGetIntegerv(GL_VERTEX_PROGRAM_POSITION_ARB, &pos);
-
- printf("Current position: %d\n", pos);
-
- printf("Current temporary registers:\n");
- for (i = 0; i < 4; i++) {
- GLfloat v[4];
- char s[10];
- sprintf(s, "R%d", i);
- glGetProgramRegisterfvMESA(GL_VERTEX_PROGRAM_ARB, strlen(s), s, v);
- printf("R%d = %g, %g, %g, %g\n", i, v[0], v[1], v[2], v[3]);
- }
- }

-
- /* define/bind a vertex program */
-
- glEnable(GL_VERTEX_PROGRAM);
-
- /* render something */
- glBegin(GL_POINTS);

-
-Overview
-
- This extension modifies the way in which points are rendered,
- specifically when they're textured. When SPRITE_POINT_MESA is enabled
- a point is rendered as if it were a quadrilateral with unique texture
- coordinates at each vertex. This extension effectively turns points
- into sprites which may be rendered more easily and quickly than using
- conventional textured quadrilaterals.
-
- When using point size > 1 or attenuated points this extension is an
- effective way to render many small sprite images for particle systems
- or other effects.
-
-Issues:
-
- 1. How are the texture coordinates computed?
-
- The lower-left corner has texture coordinate (0,0,r,q).
- The lower-right, (1,0,r,q). The upper-right, (1,1,r,q).
- The upper-left, (0,1,r,q).
-
- 2. What about texgen and texture matrices?
-
- Texgen and the texture matrix have no effect on the point's s and t
- texture coordinates. The r and q coordinates may have been computed
- by texgen or the texture matrix. Note that with a 3D texture and/or
- texgen that the r coordinate could be used to select a slice in the
- 3D texture.
-
- 3. What about point smoothing?
-
- When point smoothing is enabled, a triangle fan could be rendered
- to approximate a circular point. This could be problematic to
- define and implement so POINT_SMOOTH is ignored when drawing sprite
- points.
-
- Smoothed points can be approximated by using an appropriate texture
- images, alpha testing and blending.
-
- POLYGON_SMOOTH does effect the rendering of the quadrilateral, however.
-
- 4. What about sprite rotation?
-
- There is none. Sprite points are always rendered as window-aligned
- squares. One could define rotated texture images if desired. A 3D
- texture and appropriate texture r coordinates could be used to
- effectively specify image rotation per point.
-
- 5. What about POLYGON_MODE?
-
- POLYGON_MODE does not effect the rasterization of the quadrilateral.
-
- 6. What about POLYGON_CULL?
-
- TBD. Polygon culling is normally specified and implemented in the
- transformation stage of OpenGL. However, some rasterization hardware
- implements it later during triangle setup.
-
- Polygon culling wouldn't be useful for sprite points since the
- quadrilaterals are always defined in counter-clockwise order in
- window space. For that reason, polygon culling should probably be
- ignored.
-
- 7. Should sprite points be alpha-attenuated if their size is below the
- point parameter's threshold size?
-
- 8. Should there be an advertisized maximum sprite point size?
-
- No. Since we're rendering the point as a quadrilateral there's no
- need to limit the size.

- Section ???.
-
- When SPRITE_POINT_MESA is enabled points are rasterized as screen-
- aligned quadrilaterals. If the four vertices of the quadrilateral
- are labeled A, B, C, and D, starting at the lower-left corner and moving
- counter-clockwise around the quadrilateral, then the vertex and
- texture coordinates are computed as follows:
-
- vertex window coordinate texture coordinate
- A (x-r, y-r, z, w) (0, 0, r, q)
- B (x+r, y-r, z, w) (1, 0, r, q)
- C (x+r, y+r, z, w) (1, 1, r, q)
- D (x-r, y+r, z, w) (0, 1, r, q)
-
- where x, y, z, w are the point's window coordinates, r and q are the
- point's 3rd and 4th texture coordinates and r is half the point's
- size. The other vertex attributes (such as the color and fog coordinate)
- are simply duplicated from the original point vertex.
-
- Point size may either be specified with PointSize or computed
- according to the EXT_point_parameters extension.
-
- The new texture coordinates are not effected by texgen or the texture
- matrix. Note, however, that the texture r and q coordinates are passed
- unchanged and may have been computed with texgen and/or the texture
- matrix.
-
- If multiple texture units are present the same texture coordinate is
- used for all texture units.
-
- The point is then rendered as if it were a quadrilateral using the
- normal point sampling rules. POLYGON_MODE does not effect the
- rasterization of the quadrilateral but POLYGON_SMOOTH does.
-
- POINT_SMOOTH has no effect when SPRITE_POINT_MESA is enabled.

- OpenGL 1.2 is required.
- The extension is written against the OpenGL 1.2 Specification
-
-Overview
-
- Provides the application with means to enable and disable logging
- of GL calls including parameters as readable text. The verbosity
- of the generated log can be controlled. The resulting logs are
- valid (but possibly incomplete) C code and can be compiled and
- linked for standalone test programs. The set of calls and the
- amount of static data that is logged can be controlled at runtime.
- The application can add comments and enable or disable tracing of GL
- operations at any time. The data flow from the application to GL
- and back is unaffected except for timing.
-
- Application-side implementation of these features raises namespace
- and linkage issues. In the driver dispatch table a simple
- "chain of responsibility" pattern (aka "composable piepline")
- can be added.
-
-IP Status
-
- The extension spec is in the public domain. The current implementation
- in Mesa is covered by Mesa's XFree86-style copyright by the authors above.
- This extension is partially inspired by the Quake2 QGL wrapper.
-
-Issues
-
-
- (1) Is this Extension obsolete because it can
- be implemented as a wrapper DLL?
-
- RESOLVED: No. While certain operating systems (Win32) provide linkers
- that facilitate this kind of solution, other operating systems
- (Linux) do not support hierarchical linking, so a wrapper solution
- would result in symbol collisions.
- Further, IHV's might have builtin support for tracing GL execution
- that enjoys privileged access, or that they do not wish to separate
- the tracing code from their driver code base.
-
- (2) Should the Trace API explicitely support the notion of "frames?
- This would require hooking into glXSwapBuffers calls as well.
-
- RESOLVED: No. The application can use NewTraceMESA/EndTraceMESA
- and TraceComment along with external parsing tools to split the
- trace into frames, in whatever way considered adequate.
-
- (2a) Should GLX calls be traced?
-
- PBuffers and other render-to-texture solutions demonstrate that
- context level commands beyond SwapBuffers might have to be
- traced. The GL DLL exports the entry points, so this would not
- be out of the question.
-
- (3) Should the specification mandate the actual output format?
-
- RESOLVED: No. It is sufficient to guarantee that all data and commands
- will be traced as requested by Enable/DisableTraceMESA, in the order
- encountered. Whether the resulting trace is available as a readable
- text file, binary metafile, compilable source code, much less which
- indentation and formatting has been used, is up to the implementation.
- For the same reason this specification does not enforce or prohibit
- additional information added to the trace (statistics, profiling/timing,
- warnings on possible error conditions).
-
- (4) Should the comment strings associated with names and pointer (ranges)
- be considered persistent state?
-
- RESOLVED: No. The implementation is not forced to use this information
- on subsequent occurences of name/pointer, and is free to consider it
- transient state.
-
- (5) Should comment commands be prohibited between Begin/End?
-
- RESOLVED: Yes, with the exception of TraceCommentMESA. TraceCommentMESA
- is transient, the other commands might cause storage of persistent
- data in the context. There is no need to have the ability mark names
- or pointers between Begin and End.
-

-
-Additions to Chapter 4 of the OpenGL 1.2.1 Specification (OpenGL Operation)
-
- None.
-
-Additions to Chapter 5 of the OpenGL 1.2.1 Specification (Special Functions)
-
- Add a new section:
-
- 5.7 Tracing
-
- The tracing facility is used to record the execution of a GL program
- to a human-readable log. The log appears as a sequence of GL commands
- using C syntax. The primary intention of tracing is to aid in program
- debugging.
-
- A trace is started with the command
-
- void NewTraceMESA( bitfield mask, const GLubyte * traceName )
-
- <mask> may be any value accepted by PushAttrib and specifies a set of
- attribute groups. The state values included in those attribute groups
- is written to the trace as a sequence of GL commands.
-
- <traceName> specifies a name or label for the trace. It is expected
- that <traceName> will be interpreted as a filename in most implementations.
-
- A trace is ended by calling the command
-
- void EndTraceMESA( void )
-
- It is illegal to call NewTraceMESA or EndTraceMESA between Begin and End.
-
- The commands
-
- void EnableTraceMESA( bitfield mask )
- void DisableTraceMESA( bitfield mask )
-
- enable or disable tracing of different classes of GL commands.
- <mask> may be the union of any of TRACE_OPERATIONS_BIT_MESA,
- TRACE_PRIMITIVES_BIT_MESA, TRACE_ARRAYS_BIT_MESA, TRACE_TEXTURES_BIT_MESA,
- and TRACE_PIXELS_BIT_MESA. The special token TRACE_ALL_BITS_MESA
- indicates all classes of commands are to be logged.
-
- TRACE_OPERATIONS_BIT_MESA controls logging of all commands outside of
- Begin/End, including Begin/End.
-
- TRACE_PRIMITIVES_BIT_MESA controls logging of all commands inside of
- Begin/End, including Begin/End.
-
- TRACE_ARRAYS_BIT_MESA controls logging of VertexPointer, NormalPointer,
- ColorPointer, IndexPointer, TexCoordPointer and EdgeFlagPointer commands.
-
- TRACE_TEXTURES_BIT_MESA controls logging of texture data dereferenced by
- TexImage1D, TexImage2D, TexImage3D, TexSubImage1D, TexSubImage2D, and
- TexSubImage3D commands.
-
- TRACE_PIXELS_BIT_MESA controls logging of image data dereferenced by
- Bitmap and DrawPixels commands.
-
- TRACE_ERRORS_BIT_MESA controls logging of all errors. If this bit is
- set, GetError will be executed whereever applicable, and the result will
- be added to the trace as a comment. The error returns are cached and
- returned to the application on its GetError calls. If the user does not
- wish the additional GetError calls to be performed, this bit should not
- be set.
-
- The command
-
- void TraceCommentMESA( const ubyte* comment )
-
- immediately adds the <comment> string to the trace output, surrounded
- by C-style comment delimiters.
-
- The commands
-
- void TraceTextureMESA( uint name, const ubyte* comment )
- void TraceListMESA( uint name, const ubyte* comment )
-
- associates <comment> with the texture object or display list specified
- by <name>. Logged commands which reference the named texture object or
- display list will be annotated with <comment>. If IsTexture(name) or
- IsList(name) fail (respectively) the command is quietly ignored.
-
- The commands
-
- void TracePointerMESA( void* pointer, const ubyte* comment )
-
- void TracePointerRangeMESA( const void* first,
- const void* last,
- const ubyte* comment )
-
- associate <comment> with the address specified by <pointer> or with
- a range of addresses specified by <first> through <last>.
- Any logged commands which reference <pointer> or an address between
- <first> and <last> will be annotated with <comment>.
-
- The command
-
- void TraceAssertAttribMESA( bitfield attribMask )
-
- will add GL state queries and assertion statements to the log to
- confirm that the current state at the time TraceAssertAttrib is
- executed matches the current state when the trace log is executed
- in the future.
-
- <attribMask> is any value accepted by PushAttrib and specifies
- the groups of state variables which are to be asserted.
-
- The commands NewTraceMESA, EndTraceMESA, EnableTraceMESA, DisableTraceMESA,
- TraceAssertAttribMESA, TraceCommentMESA, TraceTextureMESA, TraceListMESA,
- TracePointerMESA and TracePointerRangeMESA are not compiled into display lists.
-
-
- Examples:
-
- The command NewTraceMESA(DEPTH_BUFFER_BIT, "log") will query the state
- variables DEPTH_TEST, DEPTH_FUNC, DEPTH_WRITEMASK, and DEPTH_CLEAR_VALUE
- to get the values <test>, <func>, <mask>, and <clear> respectively.
- Statements equivalent to the following will then be logged:
-
- glEnable(GL_DEPTH_TEST); (if <test> is true)
- glDisable(GL_DEPTH_TEST); (if <test> is false)
- glDepthFunc(<func>);
- glDepthMask(<mask>);
- glClearDepth(<clear>);
-
-
- The command TraceAssertAttribMESA(DEPTH_BUFFER_BIT) will query the state
- variables DEPTH_TEST, DEPTH_FUNC, DEPTH_WRITEMASK, and DEPTH_CLEAR_VALUE
- to get the values <test>, <func>, <mask>, and <clear> respectively.
- The resulting trace might then look will like this:
-
- {
- GLboolean b;
- GLint i;
- GLfloat f;
- b = glIsEnabled(GL_DEPTH_TEST);
- assert(b == <test>);
- glGetIntegerv(GL_DEPTH_FUNC, &i);
- assert(i == <func>);
- glGetIntegerv(GL_DEPTH_MASK, &i);
- assert(i == <mask>);
- glGetFloatv(GL_DEPTH_CLEAR_VALUE, &f);
- assert(f == <clear>);
- }
-
-
-Additions to Chapter 6 of the OpenGL 1.2.1 Specification
- (State and State Requests)
-
- Querying TRACE_MASK_MESA with GetIntegerv, GetFloatv, GetBooleanv or
- GetDoublev returns the current command class trace mask.
-
- Querying TRACE_NAME_MESA with GetString returns the current trace name.
-
-
-Additions to Appendix A of the OpenGL 1.2.1 Specification (Invariance)
-
- The MESA_trace extension can be used in a way that does not affect data
- flow from application to OpenGL, as well as data flow from OpenGL to
- application, except for timing, possible print I/O. TRACE_ERRORS_BIT_MESA
- will add additional GetError queries. Setting a trace mask with NewTraceMESA
- as well as use of TraceAssertAttribMESA might cause additional state queries.
- With the possible exception of performance, OpenGL rendering should not be
- affected at all by a properly chosen logging operation.
-
-Additions to the AGL/GLX/WGL Specifications
-
- None.
-
-GLX Protocol
-
- None. The logging operation is carried out client-side, by exporting
- entry points to the wrapper functions that execute the logging operation.
-
-Errors
-
- INVALID_OPERATION is generated if any trace command except TraceCommentMESA
- is called between Begin and End.
-
-New State
-
- The current trace name and current command class mask are stored
- per-context.
-
-New Implementation Dependent State
-
- None.

- libglide3x.a, libglide3x.so
- Type:
- make linux-glide
- or
- make linux-x86-glide
-
-
-
-Compilation defines:
---------------------
-
-FX_DEBUG
- enable driver debug code
-FX_TRAP_GLIDE
- enable Glide trace code
-FX_PACKEDCOLOR
- use packed color in vertex structure
-FX_TC_NAPALM
- map GL_COMPRESSED_RGB[A] to FXT1. Works with VSA100-based cards only.
-FX_COMPRESS_S3TC_AS_FXT1_HACK
- map S3TC to FXT1

-
-
-
-Environment variables:
-----------------------
-
-The following environment variables affect MesaFX. Those that affect Glide
-only, are beyond the scope of this section. Entries that don't have a "Value"
-field, can have any value whatsoever
- ex: set MESA_FX_IGNORE_CMBEXT=y
-
-"Note" (*) means that the environment variable affects Glide, too; also, if
-the var is not found in the environment, it is searched in windoze registry.
-"Note" (!) means that the environment variable is not working as expected;
-may have undefined effects, might have effects only at Glide level or might
-not have any effect whatsoever. Caveat emptor! Those are to be revised soon.
-
-It is recommended to leave the envvars alone, so that Mesa/Glide will run with
-default values. Use them only when you experience crashes or strange behavior.

-Info for Mesa 4.1
------------------
-
-The 3dfx Glide driver in Mesa is disabled by default. Not too many people
-use this driver anymore and at some point down the road it will be dropped.
-
-To use/enable the Glide driver either do this:
-
-'./configure --with-glide=DIR' Where DIR is the location of Glide, like
- /usr/ or /usr/local
-
-OR
-
-'make linux-x86-glide' If using the old-style Makefile system.
-
-The rest of this file hasn't changed since Mesa 3.3. Some of it's out of
-date, but some is still valid.
-
-
-
-What do you need ?
-------------------
-
- - A PC with a 3Dfx Voodoo1/2 Graphics or Voodoo Rush based board
- (Pure3D, Monster 3D, R3D, Obsidian, Stingray 128/3D, etc.).
- The Quantum3D Obsidian3D-2 X-24 requires some special env. setting
- under Linux (more information in the "Useful Glide Environment
- Variables");
-
- - The 3Dfx Glide library 2.3 or later for your OS (the 2.4 works fine).
- The Voodoo2 requires the Glide library 2.51. The Glide 3.1 is not
- compatible with the Glide 2.x so it doesn't work with the current
- version of the driver;
-
- - A compiler supported by the Glide library (Micro$oft VC++ (tested),
- Watcom (tested), GCC for Linux (tested), etc.);
-
- - It's nice to have two monitors - one for your normal graphics
- card and one for your 3Dfx card. If something goes wrong with
- an application using the 3Dfx hardware you can still see your
- normal screen in order to recover.
-
-
-
-Tested on:
-----------
- Windows 95 - David Bucciarelli
- Windows NT - Henri Fousse
- MS-DOS
- Linux - Daryll Strauss, Brian Paul, David Bucciarelli
- FreeBSD
- BeOS - Duncan Wilcox
- MacOS - Fazekas Miklos
-
-
-What is able to do ?
---------------------
-
- - It is able accelerate points, lines and polygon with flat
- shading, gouraud shading, Z-buffer, texture mapping, blending, fog and
- antialiasing (when possible). There is also the support for rendering
- in a window with a slow trick for the Voodoo Graphics (available only
- for Linux) and at full speed with the Voodoo Rush chipset.
- Under Linux is also possible to switch on-the-fly between the fullscreen
- and in-window rendering hack.
- There is also the support for using more than one Voodoo Graphics in the
- some application/PC (you can create one context for each board and use
- multiple video outputs for driving monitors, videoprojectors or HMDs).
- The driver is able to fallback to pure software rendering when afeature
- isn't supported by the Voodoo hardware (however software rendering is
- very slow compared to hardware supported rendering)
-
-
-
-How to compile:
----------------
-
-Linux:
-------
- Here are the basic steps for using the 3Dfx hardware with Mesa
- on Linux:
-
- - You'll need the Glide library and headers. Mesa expects:
- /usr/local/glide/include/*.h // all the Glide headers
- /usr/local/glide/lib/libglide2x.so
-
- If your Glide libraries and headers are in a different directory
- you'll have to modify the Mesa-config and mklib.glide files.
-
- - Unpack the MesaLib-3.1.tar.gz and MesaDemos-3.1.tar.gz archives;
-
- - If you're going to use a newer Mesa/Glide driver than v0.27 then
- unpack the new driver archive over the Mesa directory.
-
- - In the Mesa-3.1 directory type "make linux-glide"
-
- - Compilation _should_ finish without errors;
-
- - Set your LD_LIBRARY_PATH environment variable so that the
- libglide2x.so and Mesa library files can be found. For example:
- setenv LD_LIBRARY_PATH "/usr/local/glide/lib:/SOMEDIR/Mesa-3.1/lib"
-
- - You'll have to run Glide-based programs as root or set the suid
- bit on executables;
-
- - Try a demo:
- cd gdemos
- su
- setenv MESA_GLX_FX f
- ./gears (hit ESC to exit)
-
- - You can find the demos especially designed for the Voodoo driver in
- in the Mesa-3.1/3Dfx/demos directory (type "make" in order to compile
- everything).
-
-MacOS:
-------
- Check the WEB page at http://valerie.inf.elte.hu/~boga/Mesa.html
-
-MS Windows:
------------
-
- For the MSVC++:
- - The glide2x.lib have to be in the default MSVC++ lib directory;
-
- - The Glide headers have to be in the default MSVC++ include directory;
-
- - You must have the vcvars32.bat script in your PATH;
-
- - Go to the directory Mesa-3.1 and run the mesafx.bat;
-
- - The script will compile everything (Mesa-3.1/lib/OpenGL32.{lib,dll},
- Mesa-3.1/lib/GLU32.{lib,dll}, Mesa-3.1/lib/GLUT32.{lib,dll} and
- Voodoo demos);
-
- - At the end, you will be in the Mesa-3.1/3Dfx/demos directory;
-
- - Try some demo (fire.exe, teapot.exe, etc.) in order to check if
- everything is OK (you can use Alt-Tab or Ctrl-F9 to switch between
- the Voodoo screen and the windows desktop);
-
- - Remember to copy the Mesa OpenGL32.dll, GLU32.dll and GLUT32.dll in the
- some directory were you run your Mesa based applications.
-
- - I think that you can easy change the Makefile.fx files in order
- to work with other kind of compilers;
-
- - To discover how open the 3Dfx screen, read the sources under
- the Mesa-3.1/3Dfx/demos directory. You can use the GLUT library or
- the Diego Picciani's wgl emulator.
-
- NOTE: the MSVC++ 5.0 optimizer is really buggy. Also if you install the
- SP3, you could have some problem (you can disable optimization in order
- solve these kind of problems).
-
-
-Doing more with Mesa & Linux Glide:
------------------------------------
-
- The MESA_GLX_FX environment variable can be used to coax most
- GLX-based programs into using Glide (and the __GLUT library
- is GLX-based__).
-
- Full-screen 3Dfx rendering:
- ---------------------------
-
- 1. Set the MESA_GLX_FX variable to "fullscreen":
-
- ksh:
- export MESA_GLX_FX = "fullscreen"
- csh:
- setenv MESA_GLX_FX fullscreen
-
- 2. As root, run a GLX-based program (any GLUT demo on Linux).
-
- 3. Be careful: once the 3Dfx screen appears you won't be able
- to see the GLUT windows on your X display. This can make using
- the mouse tricky! One solution is to hook up your 3Dfx card to
- a second monitor. If you can do this then set these env vars
- first:
-
- setenv SST_VGA_PASS 1
- setenv SST_NOSHUTDOWN
-
- or for the Voodoo2:
-
- setenv SSTV2_VGA_PASS 1
- setenv SSTV2_NOSHUTDOWN
-
- Rendering into an X window with the help of the Voodoo hardware:
- ----------------------------------------------------------------
-
- 1. Start your X server in 16 bpp mode (XFree86: startx -- -bpp 16)
- in order to have the best performance and the best visual
- quality. However you can use any visual depth supported by X.
-
- 2. Set the following environment variables:
- export MESA_GLX_FX="window" # to enable window rendering
- export SST_VGA_PASS=1 # to stop video signal switching
- export SST_NOSHUTDOWN=1 # to stop video signal switching
- OR
- setenv MESA_GLX_FX window
- setenv SST_VGA_PASS 1
- setenv SST_NOSHUTDOWN 1
-
- (the Voodoo2 requires to use "SSTV2_" instead "SST_").
-
- 3. As root, try running a GLX-based program
-
- How does it work? We use the 3Dfx hardware to do rendering then
- copy the image from the 3Dfx frame buffer into an X window when
- the SwapBuffers() function is called. The problem with this
- idea is it's slow. The image must be copied from the 3Dfx frame
- buffer to main memory then copied into the X window (and when the X
- visual depth doesn't match the Voodoo framebufffer bit per pixel, it
- is required also a pixel format translation).
-
- NOTE: the in-window rendering feature only works with double-buffering.
-
-
- On the fly switching between in window rendering and full screen rendering
- --------------------------------------------------------------------------
-
- The Mesa 2.6 has introduced the capability of switching
- on-the-fly between the fullscreen/fullspeed rendering and the in-window
- hack and vice versa. The on-the-fly switching requires a direct support
- by the application but it is really easy to add. You have to start
- your X server in 16 bpp mode and to add the following lines to your
- application:
-
- #if defined(FX) && define(XMESA)
- #include <GL/xmesa.h>
-
- static int fullscreen=1;
- #endif
-
- ...
-
- /* In the GLUT keyboard event callback */
-
- #if defined(FX) && !define(WIN32)
- case ' ':
- fullscreen=(!fullscreen);
- XMesaSetFXmode(fullscreen ? XMESA_FX_FULLSCREEN : XMESA_FX_WINDOW);
- break;
- #endif
- ...
-
- See the 3Dfx/demos/tunnel.c program
- for an example. You have to set the -DXMESA flag in the Makefile's COPTS
- to enable it.
-
- Rendering into an X window with the X11 software driver:
- --------------------------------------------------------
-
- Set the MESA_GLX_FX variable to "disable" your GLX-based program will use
- the X11 software driver (the 3Dfx hardware isn't used at all).
-
-
-
-Useful Glide Environment Variables:
------------------------------------
-
- - To disable the 3Dfx logo, set the FX_GLIDE_NO_SPLASH variable.
-
- - To disable video signal switching:
- setenv SST_VGA_PASS 1
- setenv SST_NOSHUTDOWN
- or for the Voodoo2:
- setenv SSTV2_VGA_PASS 1
- setenv SSTV2_NOSHUTDOWN
-
- - To set the default screen refresh rate:
- setenv SST_SCREENREFRESH=75
-
- the supported values are 60, 70, 72, 75, 80, 85, 90, 100, 120.
-
- - To force the Mesa library to swap buffers as fast as possible,
- without any vertical blanking synchronization (useful for benchmarks):
- setenv FX_GLIDE_SWAPINTERVAL 0
- setenv SST_SWAP_EN_WAIT_ON_VIDSYNC 0
-
- - You can slight improve the performances of your Voodoo1 board with
- the following env. var.:
- setenv SST_FASTMEM 1
- setenv SST_PCIRD 1
- setenv SST_GRXCLK 57
-
- (don't use this setting with the Quantum3D 100SB or with any other
- SLI configuration: it will hang everything !).
- The following setting can be used with the Voodoo2:
- setenv SSTV2_FASTMEM_RAS_READS=1
- setenv SSTV2_FASTPCIRD=1
- setenv SSTV2_GRXCLK=95
-
- - The Quantum3D Obsidian3D-2 X-24 requires some special env. setting
- in order to work under Linux:
-
- export SSTV2_FT_CLKDEL=5
- export SSTV2_TF0_CLKDEL=7
- export SSTV2_TF1_CLKDEL=7
- export SSTV2_TF2_CLKDEL=7
- export SSTV2_SLIM_VIN_CLKDEL=3
- export SSTV2_SLIM_VOUT_CLKDEL=2
- export SSTV2_SLIS_VIN_CLKDEL=3
- export SSTV2_SLIS_VOUT_CLKDEL=2
-
- (Thanks to Phil Ross for this trick).
-
-
-
-
-The Mesa/Voodoo Environment Variables:
---------------------------------------
-
- - Only for Windows/Voodoo Rush users, if you define the
- env. var. MESA_WGL_FX:
- export MESA_WGL_FX=fullscreen
- you will get fullscreen rendering;
-
- - Only for Windows/Voodoo Rush users, if you define the
- env. var. MESA_WGL_FX:
- export MESA_WGL_FX=window
- you will get window rendering (default value);
-
- - Only for Linux users, you can find more informations about
- the env. var. MESA_GLX_FX in the "Doing more with Mesa & Linux Glide"
- section;
-
- - If you define the env. var. MESA_FX_SWAP_PENDING:
- export MESA_FX_SWAP_PENDING=4
- you will able to set the maximum number of swapbuffers
- commands in the Voodoo FIFO after a swapbuffer (default value: 2);
-
- - If you define the env. var. MESA_FX_INFO:
- export MESA_FX_INFO=1
- you will get some useful statistic.
-
- - If you define the env. var. MESA_FX_NO_SIGNALS:
- export MESA_FX_NO_SIGNALS=1
- Mesa/FX will not install atexit() or signal() handlers.
-
-
-
-Know BUGS and Problems:
------------------------
-
- - fog doesn't work in the right way when using the glDepthRange() function;
-
- - Maximum texture size: 256x256 (this is an hardware limit);
-
- - Texture border aren't yet supported;
-
- - A GL_BLEND in a glTexEnv() is not supported (it is an hardware limit);
-
- - Use the glBindTexture extension (standard in OpenGL 1.1) for texture
- mapping (the old way: glTexImage inside a display list, download
- the texture map each time that you call the display list !!!);
-
- - Stencil buffer and Accumulation buffer are emulated in software (they are not
- directly supported by the Hardware);
-
- - Color index mode not implemented (this is an hardware limit);
-
- - Thre is an know bug in the Linux Glide library so the in-window-rendering hack
- and any other operations that requires to read the Voodoo frame buffer
- (like the accumulation buffer support) doesn't work on Voodoo SLI cards.
-
- - The driver switch to pure software (_slow_) rendering when:
-
- - Stencil enabled;
- - Using the Accumulation buffer;
- - Blend enabled and blend equation != GL_FUNC_ADD_EXT;
- - Color logic operation enabled and color logic operation != GL_COPY;
- - Using GL_SEPARATE_SPECULAR_COLOR;
- - The four values of glColorMask() aren't the some;
- - Texture 1D or 3D enabled;
- - Texture function is GL_BLEND;
- - Using the Multitexture extension with Voodoo cards with only one TMU;
- - Using the Multitexture extension with Voodoo cards with more than
- one TMU, and texture function isn't GL_MODULATE;
- - Point size is != 1.0 or point params vector != (1.0,0.0,0.0);
- - Line width != 1.0 or using stipple lines.
- - Using polygon offset or stipple polygons;
-
- NOTE: this is list is not yet complete.
-
-
-Hints and Special Features:
----------------------------
-
- - Under Linux and with a Voodoo Graphics board, you can use
- XMesaSetFXmode(XMESA_FX_FULLSCREEN or XMESA_FX_WINDOW) in order to
- switch on the fly between fullscreen rendering and the in-window-rendering
- hack.
-
- - The driver is able to use all the texture memory available: 2/4MB on
- Voodoo1 boards and 8MB (!) on high-end Voodoo1 and Voodoo2 boards.
-
- - Trilinear filtering is fully supported on Voodoo boards with two TMUs
- (high-end Voodoo1 boards and Voodoo2 boards). When only one TMU is
- available the driver fallback to bilinear filter also if you ask
- for trilinear filtering.
-
- - The Voodoo driver support multiple Voodoo Graphics boards in the
- some PC. Using this feature, you can write applications that use
- multiple monitors, videoprojectors or HMDs for the output. See
- Mesa-3.1/3Dfx/demos/tunnel2.c for an example of how setup one
- context for each board.
-
- - The v0.19 introduces a new powerful texture memory manager: the
- texture memory is used as a cache of the set of all defined texture
- maps. You can now define several MBs of texture maps also with a 2MB
- of texture memory (the texture memory manager will do automatically
- all the swap out/swap in
- texture memory work). The new texture memory manager has also
- solved a lot of other bugs/no specs compliance/problems
- related to the texture memory usage.
-
- - Use triangles and quads strip: they are a LOT faster than sparse
- triangles and quads.
-
- - The Voodoo driver supports the GL_EXT_paletted_texture. it works
- only with GL_COLOR_INDEX8_EXT, GL_RGBA palettes and the alpha value
- is ignored because this is a limitation of the current Glide
- version and of the Voodoo hardware. See Mesa-3.1/3Dfx/demos/paltex.c for
- a demo of this extension.
-
- - The Voodoo driver directly supports 3Dfx Global Palette extension.
- It was written for GLQuake and I think that it isn't a good idea
- to use this extension for any other purpose (it is a trick). See
- Mesa-3.1/3Dfx/demos/glbpaltex.c for a demo of this extension.
-
- - The Voodoo driver chooses the screen resolution according to the
- requested window size. If you open a 640x480 window, you will get
- a 640x480 screen resolution, if you open a 800x600 window, you
- will get a 800x600 screen resolution, etc.
- Most GLUT demos support the '-geometry' option, so you can choose
- the screen resolution: 'tunnel -geometry 800x600'.
- Clearly, you Voodoo board must have enough framebuffer RAM (otherwise
- the window creation will fail).
-
- - The glGetString(GL_RENDERER) returns more information
- about the hardware configuration: "Mesa Glide <version>
- <Voodoo_Graphics|Voodoo_Rush|UNKNOWN> <num> CARD/<num> FB/
- <num> TM/<num> TMU/<NOSLI|SLI>"
- where: <num> CARD is the card used for the current context,
- <num> FB is the number of MB for the framebuffer,
- <num> TM is the number of MB for the texture memory,
- <num> TMU is the number of TMU. You can try to run
- Mesa/demos/glinfo in order to have an example of the output.
-

-FAQ:
-----
-
-For a complete FAQ check the Bernd Kreimeier's Linux 3Dfx HOWTO
-available at http://www.gamers.org/dEngine/xf3D (it includes also
-a lot of informations not strictly related to Linux, so it can be
-useful also if you don't use Linux)
-
-1. What is 3Dfx?
-
-3Dfx Interactive, Inc. is the company which builds the VooDoo 3-D graphics
-chipset (and others) used in popular PC cards such as the Diamond Monster 3D
-and the Orchid Righteous 3D (more informations at http://www.3dfx.com).
-
-
-2. What is Glide?
-
-Glide is a "thin" programming interface for the 3Dfx hardware. It was
-originally written for Windows/Intel but has been ported to Linux/Intel
-by Daryll Strauss.
-
-3Dfx, Inc. should be applauded for allowing the Linux version of Glide
-to be written.
-
-You can directly program with the Glide library if you wish. You can
-obtain Glide from the "Developer" section of the 3Dfx website: www.3dfx.com
-There's a Linux/Glide newsgroup at news://news.3dfx.com/3dfx.glide.linux
-
-
-3. What is fxmesa?
-
-"fxmesa" is the name of the Mesa device driver for the 3Dfx Glide library.
-It was written by David Bucciarelli and others. It works on both Linux
-and Windows. Basically, it allows you to write and run OpenGL-style programs
-on the 3Dfx hardware.
-
-
-4. What is GLQuake?
-
-Quake is a very popular game from id software, Inc. See www.idsoftware.com
-GLQuake is a version of Quake written for OpenGL. There is now a Linux
-version of GLQuake with works with the Mesa/3Dfx/Glide combo.
-
-Here's what you need to run GLQuake on Linux:
- PC with 100MHz Pentium or better
- a 3Dfx-based card
- Mesa 3.1 libraries: libMesaGL.so libMesaGLU.so
- Glide 2.4 libraries: libglide2x.so libtexus.so
- GLQuake for Linux.
-
-Also, the windows version of GLQuake works fine with the Mesa OpenGL32.dll,
-you have only to copy the Mesa-3.1/lib/OpenGL32.dll in the GLQuake directory
-in order to test 'MesaQuake'.
-
-
-5. What is GLUT?
-
-GLUT is Mark Kilgard's OpenGL Utility Toolkit. It provides an API for
-writing portable OpenGL programs with support for multiple windows, pop-
-up menus, event handling, etc.
-
-Check the Mark's home page for more informations (http://reality.sgi.com/mjk_asd).
-
-Every OpenGL programmer should check out GLUT.
-
-GLUT on Linux uses GLX.
-
-
-6. What is GLX?
-
-GLX is the OpenGL extension to the X Window System. I defines both a
-programming API (glX*() functions) and a network protocol. Mesa implements
-an emulation of GLX on Linux. A real GLX implementation would requires
-hooks into the X server. The 3Dfx hardware can be used with GLX-based
-programs via the MESA_GLX_FX environment variable.
-
-
-7. Is the Voodoo driver able to use the 4Mb texture memory of
-the Pure3D boards ?
-
-Yes, the Voodoo driver v0.20 includes the support for Voodoo
-Graphics boards with more than 2Mb of texture memory.
-
-
-8. Do the Voodoo driver support the Voodoo Rush under Windows ?
-
-Yes, Diego Picciani has developed the support for the Voodoo
-Rush but David Bucciarelli has a Pure3D and a Monster3D and Brian Paul
-has a Monster3D, so the new versions of the Mesa/Voodoo sometime are
-not tested with the Voodoo Rush.
-
-
-9. Do the Voodoo driver support the Voodoo Rush under Linux ?
-
-No because the Linux Glide doesn't (yet) support the Voodoo Rush.
-
-
-10. Can I sell my Mesa/Voodoo based software and include
-a binary copy of the Mesa in order to make the software
-working out of the box ?
-
-Yes.
-
-
-11. Which is the best make target for compiling the Mesa for
-Linux GLQuake ('make linux-glide', 'make linux-386-glide', etc.) ?
-
-'make linux-386-opt-glide' for Voodoo1 and 'make linux-386-opt-V2-glide'
-for Voodoo2 boards because it doesn't include the '-fPIC'
-option (4-5% faster).
-
-
-12. Can I use a Mesa compiled with a 'make linux-386-opt-V2-glide'
-for my applications/programs/demos ?
-
-Yes, there is only one constrain: you can't run two Mesa applications
-at the some time. This isn't a big issue with the today Voodoo Graphics.

-AMIGA AMIWIN PORT of MESA: THE OPENGL SOFTWARE EMULATION
-========================================================
-Port by Victor Ng-Thow-Hing (victorng@dgp.toronto.edu)
-Original Author (Brian Paul (brianp@ssec.wisc.edu)
-
-Dec.1 , 1995: Port of release Mesa 1.2.5
- - Modifications made to minimize changes to Mesa distribution.
-
-Nov.25, 1995: Port of release Mesa 1.2.4
-
-
-HISTORY
-=======
-As a 3D graphics progammer, I was increasingly frustrated to see OpenGL
-appearing on so many platforms EXCEPT the Amiga. Up to now, the task
-of porting OpenGL directly from native Amiga drawing routines seemed like
-a daunting task. However, two important events made this port possible.
-
-First of all, Brian Paul wrote Mesa, the OpenGL software emulator that
-can be found on many platforms - except the Amiga and Atari (who cares
-about the latter!). This was pretty ironic considering that Mesa was
-originally prototyped on an Amiga! The second great event was when
-Holger Kruse developed AmiWin, the X11R6 server for the Amiga (definitely
-register for this great piece of software) and released a development kit
-so one could compile X programs with SAS/C.
-
-Since Mesa had X routines as its primitive drawing operations, this made
-a marriage of Mesa and Amiwin feasible. I copied over the sources from
-an ftp site, played with the code, wrote some Smakefiles, and voila,
-I had OpenGL programs displaying on my Amiga.
-
-Although the speed is nothing to be impressed about, this port can be
-potentially useful to those who want to quickly test their code in
-wireframe or perhaps learn more about programming with the OpenGL API.
-
-I hope Amiga developers will continue to write excellent software for
-their machine, especially more X clients for Amiwin. If you have any
-solutions so some of my problems in the porting notes, please send me
-some email!
-
-See you around,
-Vic.
-
-HOW TO CREATE THE LIBRARIES AND SAMPLE CODE
-===========================================
-
-Just run the shell script mklib.amiwin in the mesa directory. This will
-make all the libraries and copy them into the mesa/lib directory. If you
-don't want to compile everything, just go to the desired directory and
-type smake in that directory.
-
-Change any of the variables in the smakefiles as necessary. You will REQUIRE
-the Amiwin development kit to compile these libraries since you need X11.LIB
-and the shareable X libraries. Some examples require the AmiTCP4.0
-net.lib static link library and related header files for unix related
-header files and functions like sleep().
-
-HOW TO USE THE MESA LIBRARIES
-=============================
-
-Study the Smakefiles in the demos, samples and book directories for the
-proper SAS/C options and linkable libraries to use. Basically aux calls
-require Mesaaux.LIB, gl calls require MesaGL.LIB, glu calls MesaGLU.LIB,
-tk calls Mesatk.LIB. There is a preliminary port of MesaGLUT.LIB toolkit
-available in the lib directory with the other Mesa libraries. However,
-it seems to cause crashes on some of the sample code. Someone else may want
-to attempt a more stable port.
-
-PORTING NOTES TO AMIWIN
-=======================
-
-My strategy of porting was to leave as much of the code untouched as
-possible. I surrounded any amiga specific changes with
-#ifdef AMIWIN ... #endif or #ifndef AMIWIN ... #endif preprocessor
-symbols. The code was ported on an Amiga 2000, with Fusion 40 accelerator
-and a Picasso II graphics card. The SAS/C 6.56 compiler was used, with
-the AmiWin 2.16 X development kit.
-
-All compilations were done for a 68040 CPU with 68882 math coprocessor for
-maximum speed. Please edit the smakefile for other compilers.
-I wrote smakefiles for the directories I ported. I omitted the Windows
-and Widgets directories. The former is for MS Windows and the latter
-requires Motif, which is not easily available for the Amiga.

- Mesa / BeOS Information
-
-
-
-* Introduction
-
-Brian Paul added in Mesa 3.1 a driver for BeOS R4.5 operating system.
-This driver implements a clone of the BGLView class. This class,
-derived from BView, allows OpenGL rendering into any BeOS window. His
-driver was updated in Mesa 4.1 and again in version 6.1 by Philippe
-Houdoin, who's maintaining this driver since.
-
-Any application which uses the BGLView should be able to use Mesa
-instead of Be's OpenGL without changing any code.
-
-Since Be's OpenGL implementation (as of R5) is basically just the
-SGI sample implementation, it's pretty slow. You'll see that Mesa
-is considerably faster.
-
-
-* Source Code
-
-The source code for the driver is in src/mesa/drivers/beos/ directory.
-It's not 100% finished at this time but many GLUT-based demos are
-working. No optimizations have been made at this time.
-
-
-* Compiling
-
-Since Mesa 6.x, it can be build under BeOS with both the R5 builtin gcc version
-or more recent gcc versions available for BeOS, like this gcc version 2.95.3 for BeOS
-you can find at http://www.bebits.com/app/2157.
-Anyway, keep in mind that to take full advantage of Mesa x86 optimizations, you better
-want to use gcc 2.95.3 or sooner versions...
-
-To build Mesa-powered BeOS libGL.so version, open an Terminal window,
-move to Mesa root folder and type this command:
-
-$ make beos
-
-Note that the "beos" argument is only needed the first time to setup build config.
-Next times, typing "make" will be enough.
-
-When it finishes the Mesa based libGL.so library for
-BeOS will be in the lib/ directory, along libglut.so library.
-Several demo/test programs should have been build too under progs/* folders.
-If it stop when building one of the progs/* programs, you may want to ignore it
-and force make to move on next target by adding the -k make option:
-
-$ cd progs
-$ make -k
-
-To install it as Be's default libGL.so replacement, put it in your
-/boot/home/config/lib/ directory. All your GL/GLUT apps will use
-the Mesa based then.
-
-By default, it build a non-debug version library.
-The x86 (MMX, SSE and 3DNOW) optimizations are also supported for x86 target.
-For PowerPC BeOS flavor, sorry, Mesa don't have ppc (Altivec) optimizations
-yet.
-
-To build a DEBUG version, type instead this :
-
-$ DEBUG=1 make
-
-
-* Example Programs
-
-Look under progs/beos/ for some BGLView-based programs.
-You should find under progs/samples and progs/redbook directories GLUT-based programs too.
-They all should have been compiled along with the Mesa library.
-
-
-* GLUT
-
-A beta version of GLUT 3.7 port for BeOS, made by Jake Hamby, can be found at
-http://anobject.com/jehamby/Code/Glut-3.7-x86.zip.
-This is the version currently included in Mesa source code, and
-build in lib/libglut.so.
-
-A previous 3.5 version of this GLUT BeOS port used to be available at
-http://home.beoscentral.com/jehamby/Glut-3.5-x86.zip.
-
-They're special versions of GLUT for the BeOS platform. I don't
-believe Mark Kilgard's normal GLUT distribution includes BeOS
-support.
-
-
-* Special Features
-
-Mesa's implementation of the BGLView class has an extra member
-function: CopySubBufferMESA(). It basically works like SwapBuffers()
-but it only copies a sub region from the back buffer to the front
-buffer. This is a useful optimization for some applications.
-If you use this method in your code be sure that you check at runtime
-that you're actually using Mesa (with glGetString) so you don't
-cause a fatal error when running with Be's OpenGL.
-
-
-* Work Left To Do
-
-- BDirectWindow single buffering support is not implemented yet.
-- Color index mode is not implemented yet.
-- Reading pixels from the front buffer not implemented yet.
-- There is also a BGLScreen class in BeOS for full-screen OpenGL rendering.
- This should also be implemented for Mesa.
-- Multiple renderers add-ons support, first step toward hardware acceleration
- support.
-
-* Other contributors to this BeOS port
-
-Jake Hamby jhamby <at> anobject <dot> com
-Marcin Konicki ahwayakchih <at> neoni <dot> net
-Francois Revol revol <at> free <dot> fr
-Nathan Whitehorn nathanw <at> uchicago <dot> edu
-
-
-* Older BeOS Driver
-
-Mesa 2.6 had an earlier BeOS driver. It was based on Mesa's Off-screen
-rendering interface, not BGLView. If you're interested in the older
-driver you should get Mesa 2.6.
-
-
-* BeOS and Glide
-
-Mesa 3.0 supported the 3Dfx/Glide library on Beos. Download Mesa 3.0
-if interested. Ideally, the 3Dfx/Glide support should be updated to
-work with the new Mesa 3.1 BGLView implementation.
-
-The Glide library hasn't been updated for BeOS R4 and newer, to my knowledge,
-as of February, 1999.

- Mesa Cygwin/X11 Information
-
-
-WARNING
-=======
-
-If you installed X11 (packages xorg-x11-devel and xorg-x11-bin-dlls ) with the
-latest setup.exe from Cygwin the GL (Mesa) libraries and include are already
-installed in /usr/X11R6.
-
-The following will explain how to "replace" them.
-
-Installation
-============
-
-How to compile Mesa on Cygwin/X11 systems:
-
-1. Shared libs:
- type 'make cygwin-sl'.
-
- When finished, the Mesa DLL will be in the Mesa-x.y/lib/ and
- Mesa-x.y/bin directories.
-
-
-2. Static libs:
- type 'make cygwin-static'.
- When finished, the Mesa libraries will be in the Mesa-x.y/lib/ directory.
-
-Header and library files:
- After you've compiled Mesa and tried the demos I recommend the following
- procedure for "installing" Mesa.
-
- Copy the Mesa include/GL directory to /usr/X11R6/include:
- cp -a include/GL /usr/X11R6/include
-
- Copy the Mesa library files to /usr/X11R6/lib:
- cp -a lib/* /usr/X11R6ocal/lib
-
- Copy the Mesa bin files (used by the DLL stuff) to /usr/X11R6/bin:
- cp -a lib/cyg* /usr/X11R6/bin
-
-Xt/Motif widgets:
- If you want to use Mesa or OpenGL in your Xt/Motif program you can build
- the widgets found in either the widgets-mesa or widgets-sgi directories.
- The former were written for Mesa and the later are the original SGI
- widgets. Look in those directories for more information.
- For the Motif widgets you must have downloaded the lesstif package.
-
-
-Using the library
-=================
-
-Configuration options:
- The file src/mesa/main/config.h has many parameters which you can adjust
- such as maximum number of lights, clipping planes, maximum texture size,
- etc. In particular, you may want to change DEPTH_BITS from 16 to 32
- if a 16-bit depth buffer isn't precise enough for your application.
-
-
-Shared libraries:
- If you compile shared libraries (Win32 DLLS) you may have to set an
- environment variable to specify where the Mesa libraries are located.
- Set the PATH variable to include /your-dir/Mesa-2.6/bin.
- Otherwise, when you try to run a demo it may fail with a message saying
- that one or more DLL couldn't be found.
-
-
-Xt/Motif Widgets:
- Two versions of the Xt/Motif OpenGL drawing area widgets are included:
-
- widgets-sgi/ SGI's stock widgets
- widgets-mesa/ Mesa-tuned widgets
-
- Look in those directories for details
-
-
-Togl:
- Togl is an OpenGL/Mesa widget for Tcl/Tk.
- See http://togl.sourceforge.net for more information.
-
-
-
-X Display Modes:
- Mesa supports RGB(A) rendering into almost any X visual type and depth.
-
- The glXChooseVisual function tries its best to pick an appropriate visual
- for the given attribute list. However, if this doesn't suit your needs
- you can force Mesa to use any X visual you want (any supported by your
- X server that is) by setting the MESA_RGB_VISUAL and MESA_CI_VISUAL
- environment variables. When an RGB visual is requested, glXChooseVisual
- will first look if the MESA_RGB_VISUAL variable is defined. If so, it
- will try to use the specified visual. Similarly, when a color index
- visual is requested, glXChooseVisual will look for the MESA_CI_VISUAL
- variable.
-
- The format of accepted values is: <visual-class> <depth>
- Here are some examples:
-
- using the C-shell:
- % setenv MESA_RGB_VISUAL "TrueColor 8" // 8-bit TrueColor
- % setenv MESA_CI_VISUAL "PseudoColor 12" // 12-bit PseudoColor
- % setenv MESA_RGB_VISUAL "PseudoColor 8" // 8-bit PseudoColor
-
- using the KornShell:
- $ export MESA_RGB_VISUAL="TrueColor 8"
- $ export MESA_CI_VISUAL="PseudoColor 12"
- $ export MESA_RGB_VISUAL="PseudoColor 8"
-
-
-Double buffering:
- Mesa can use either an X Pixmap or XImage as the backbuffer when in
- double buffer mode. Using GLX, the default is to use an XImage. The
- MESA_BACK_BUFFER environment variable can override this. The valid
- values for MESA_BACK_BUFFER are: Pixmap and XImage (only the first
- letter is checked, case doesn't matter).
-
- A pixmap is faster when drawing simple lines and polygons while an
- XImage is faster when Mesa has to do pixel-by-pixel rendering. If you
- need depth buffering the XImage will almost surely be faster. Exper-
- iment with the MESA_BACK_BUFFER variable to see which is faster for
- your application.
-
-
-Colormaps:
- When using Mesa directly or with GLX, it's up to the application writer
- to create a window with an appropriate colormap. The aux, tk, and GLUT
- toolkits try to minimize colormap "flashing" by sharing colormaps when
- possible. Specifically, if the visual and depth of the window matches
- that of the root window, the root window's colormap will be shared by
- the Mesa window. Otherwise, a new, private colormap will be allocated.
-
- When sharing the root colormap, Mesa may be unable to allocate the colors
- it needs, resulting in poor color quality. This can happen when a
- large number of colorcells in the root colormap are already allocated.
- To prevent colormap sharing in aux, tk and GLUT, define the environment
- variable MESA_PRIVATE_CMAP. The value isn't significant.
-
-
-Gamma correction:
- To compensate for the nonlinear relationship between pixel values
- and displayed intensities, there is a gamma correction feature in
- Mesa. Some systems, such as Silicon Graphics, support gamma
- correction in hardware (man gamma) so you won't need to use Mesa's
- gamma facility. Other systems, however, may need gamma adjustment
- to produce images which look correct. If in the past you thought
- Mesa's images were too dim, read on.
-
- Gamma correction is controlled with the MESA_GAMMA environment
- variable. Its value is of the form "Gr Gg Gb" or just "G" where
- Gr is the red gamma value, Gg is the green gamma value, Gb is the
- blue gamma value and G is one gamma value to use for all three
- channels. Each value is a positive real number typically in the
- range 1.0 to 2.5. The defaults are all 1.0, effectively disabling
- gamma correction. Examples using csh:
-
- % setenv MESA_GAMMA "2.3 2.2 2.4" // separate R,G,B values
- % setenv MESA_GAMMA "2.0" // same gamma for R,G,B
-
- The demos/gamma.c program may help you to determine reasonable gamma
- value for your display. With correct gamma values, the color intensities
- displayed in the top row (drawn by dithering) should nearly match those
- in the bottom row (drawn as grays).
-
- Alex De Bruyn reports that gamma values of 1.6, 1.6 and 1.9 work well
- on HP displays using the HP-ColorRecovery technology.
-
- Mesa implements gamma correction with a lookup table which translates
- a "linear" pixel value to a gamma-corrected pixel value. There is a
- small performance penalty. Gamma correction only works in RGB mode.
- Also be aware that pixel values read back from the frame buffer will
- not be "un-corrected" so glReadPixels may not return the same data
- drawn with glDrawPixels.
-
- For more information about gamma correction see:
- http://www.inforamp.net/~poynton/notes/colour_and_gamma/GammaFAQ.html
-
-
-Overlay Planes
-
- Overlay planes in the frame buffer are supported by Mesa but require
- hardware and X server support. To determine if your X server has
- overlay support you can test for the SERVER_OVERLAY_VISUALS property:
-
- xprop -root | grep SERVER_OVERLAY_VISUALS
-
-
-HPCR glClear(GL_COLOR_BUFFER_BIT) dithering
-
- If you set the MESA_HPCR_CLEAR environment variable then dithering
- will be used when clearing the color buffer. This is only applicable
- to HP systems with the HPCR (Color Recovery) system.
-
-
-Extensions
-==========
- There are three Mesa-specific GLX extensions at this time.
-
- GLX_MESA_pixmap_colormap
-
- This extension adds the GLX function:
-
- GLXPixmap glXCreateGLXPixmapMESA( Display *dpy, XVisualInfo *visual,
- Pixmap pixmap, Colormap cmap )
-
- It is an alternative to the standard glXCreateGLXPixmap() function.
- Since Mesa supports RGB rendering into any X visual, not just True-
- Color or DirectColor, Mesa needs colormap information to convert RGB
- values into pixel values. An X window carries this information but a
- pixmap does not. This function associates a colormap to a GLX pixmap.
- See the xdemos/glxpixmap.c file for an example of how to use this
- extension.
-
- GLX_MESA_release_buffers
-
- Mesa associates a set of ancillary (depth, accumulation, stencil and
- alpha) buffers with each X window it draws into. These ancillary
- buffers are allocated for each X window the first time the X window
- is passed to glXMakeCurrent(). Mesa, however, can't detect when an
- X window has been destroyed in order to free the ancillary buffers.
-
- The best it can do is to check for recently destroyed windows whenever
- the client calls the glXCreateContext() or glXDestroyContext()
- functions. This may not be sufficient in all situations though.
-
- The GLX_MESA_release_buffers extension allows a client to explicitly
- deallocate the ancillary buffers by calling glxReleaseBuffersMESA()
- just before an X window is destroyed. For example:
-
- #ifdef GLX_MESA_release_buffers
- glXReleaseBuffersMESA( dpy, window );
- #endif
- XDestroyWindow( dpy, window );
-
- This extension is new in Mesa 2.0.
-
- GLX_MESA_copy_sub_buffer
-
- This extension adds the glXCopySubBufferMESA() function. It works
- like glXSwapBuffers() but only copies a sub-region of the window
- instead of the whole window.
-
- This extension is new in Mesa version 2.6
-
-
-
-Summary of X-related environment variables:
- MESA_RGB_VISUAL - specifies the X visual and depth for RGB mode (X only)
- MESA_CI_VISUAL - specifies the X visual and depth for CI mode (X only)
- MESA_BACK_BUFFER - specifies how to implement the back color buffer (X only)
- MESA_PRIVATE_CMAP - force aux/tk libraries to use private colormaps (X only)
- MESA_GAMMA - gamma correction coefficients (X only)

- Mesa 6.5 DOS/DJGPP Port v1.8
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-
-
-Description:
-~~~~~~~~~~~~
-
-Well, guess what... this is the DOS port of Mesa 6.5, for DJGPP fans... Whoa!
-The driver uses OSMesa to draw off screen, and then blits the buffer. This is
-not terribly efficient, and has some drawbacks, but saves maintenance costs.
-
-
-
-Legal:
-~~~~~~
-
-Mesa copyright applies.
-
-
-
-Installation:
-~~~~~~~~~~~~~
-
-Unzip and type:
-
- make -f Makefile.DJ [OPTIONS...]
-
-Available options:
-
- Environment variables:
- CPU optimize for the given processor.
- default = pentium
- GLIDE path to Glide3 SDK; used with FX.
- default = $(TOP)/glide3
- FX=1 build for 3dfx Glide3. Note that this disables
- compilation of most DMesa code and requires fxMesa.
- As a consequence, you'll need the DJGPP Glide3
- library to build any application.
- default = no
- X86=1 optimize for x86 (if possible, use MMX, SSE, 3DNow).
- default = no
-
- Targets:
- all: build everything
- libgl: build GL
- libglu: build GLU
- libglut: build GLUT
- clean: remove object files
- realclean: remove all generated files
-
-
-
-Tested on:
- Video card: Radeon 9500
- DJGPP: djdev 2.04 + gcc v4.1.0 + make v3.80
- OS: DOS, Win98SE, WinXP (using Videoport driver)
-
-
-
-FAQ:
-~~~~
-
-1. Compilation
-
- Q) `make' barfs and exits because it cannot find some stupid file.
- A) You need LFN support.
- A) When compiling for Glide (FX=1), pay attention to Glide path.
-
- Q) Libraries built OK, but linker complains about `vsnprintf' every time I
- compile some demo.
- A) Upgrade to DJGPP 2.04.
- A) Add `vsnprintf.c' to the CORE_SOURCES in `src/Makefile.DJ' (untested!).
- A) Patch `src/mesa/main/imports.c' with the following line:
- #define vsnprintf(buf, max, fmt, arg) vsprintf(buf, fmt, arg)
- This hack should be safe in 90% of the cases, but if anything goes wrong,
- don't come back to me crying.
-
- Q) `make' complains about DXE3 or something, yet it builds the libraries.
- A) DXE3 refers to the DJGPP dynamic modules. You'll need either the latest
- DJGPP distro, or download the separate package from my web page. Read the
- DXE3 documentation on how to use them.
- A) When compiling for Glide (FX=1), make sure `glide3x.dxe' can be found in
- LD_LIBRARY_PATH (or top `lib' directory).
-
-2. Using Mesa for DJGPP
-
- Q) Every test I tried crashes badly.
- A) If you have compiled with SSE and you're running under plain DOS, you
- have to disable SSE at run-time. See environment variables below.
-
- Q) DMesa is so SLOOOW! The Win32 OpenGL performs so much better...
- A) Is that a question? If you have a 3dfx Voodoo (any model), you're
- lucky (check http://sourceforge.net/projects/glide for the DJGPP port).
- If you haven't, sorry; everything is done in software.
-
- Q) I tried to set refresh rate w/ DMesa, but without success.
- A) Refresh rate control works only for VESA 3.0 and the 3dfx driver (in
- which case FX_GLIDE_REFRESH will be overwritten if it is defined and
- is not 0).
-
- Q) I made a simple application and it does nothing. It exits right away. Not
- even a blank screen.
- A) Software drivers (VESA/VGA/NUL) must to be constructed as single-buffered
- visuals. However, DMesaSwapBuffers must be called to get any output.
- A) Another weird "feature" is that buffer width must be multiple of 8 (I'm a
- lazy programmer and I found that the easiest way to keep buffer handling
- at peak performance ;-).
-
- Q) I'm getting a "bad font!" fatal error.
- A) Always use GLUT_STROKE_* and GLUT_BITMAP_* constants when dealing with
- GLUT fonts. If you're using `glut.dxe', then make sure GLUT_STROKE_* and
- GLUT_BITMAP_* are mapped to integer constants, not to the actual font
- address (same mechanism used for Win32 _DLL).
-
- Q) What is NUL driver good for, if I don't get any output at all?
- A) For debugging. The NUL driver is very much like OSMesa. Everything is
- done just the same as VESA/VGA drivers, only it doesn't touch your video
- hardware. You can query the actual buffer by issuing:
- DMesaGetIntegerv(DMESA_GET_BUFFER_ADDR, &buffer);
- and dump it to a file.
-
- Q) How do I query for a list of available video modes to choose as a visual?
- A) This is an ugly hack, for which I'm sure I'll burn in hell.
- First, query for a list of modes:
- n = DMesaGetIntegerv(DMESA_GET_VIDEO_MODES, NULL);
- If `n' is strictly positive, you allocate an array of pointers to a given
- struct (which is guaranteed to be extended only - not changed in future):
- struct {
- int xres, yres;
- int bpp;
- } **l = malloc(n * sizeof(void *));
- Now pass the newly allocated buffer to fill in:
- DMesaGetIntegerv(DMESA_GET_VIDEO_MODES, (GLint *)l);
- And collect the info:
- for (i = 0; i < n; i++) {
- printf("%dx%d:%d\n", l[i]->xres, l[i]->yres, l[i]->bpp);
- }
-
- Q) The GLUT is incomplete.
- A) See below.
-
-
-
-libGLUT (the toolkit):
-~~~~~~~~~~~~~~~~~~~~~~
-
-Well, this "skeletal" GLUT implementation was taken from AllegGL project and
-heavily changed. Thanks should go to Bernhard Tschirren, Mark Kilgard, Brian
-Paul and probably others (or probably not ;-). GLUT functionality will be
-extended only on an "as needed" basis.
-
-GLUT talks to hardware via PC_HW package which was put together from various
-pieces I wrote long time ago. It consists from the keyboard, mouse and timer
-drivers.
-
-My keyboard driver used only scancodes; as GLUT requires ASCII values for keys,
-I borrowed the translation tables (and maybe more) from Allegro -- many thanks
-to Shawn Hargreaves et co. Ctrl-Alt-Del (plus Ctrl-Alt-End, for Windows users)
-will shut down the GLUT engine unconditionally: it will raise SIGINT, which in
-turn will (hopefully) call the destructors, thus cleaning up your/my mess ;-)
-NB: since the DJGPP guys ensured signal handlers won't go beyond program's
-space (and since dynamic modules shall) the SIGINT can't be hooked (well, it
-can, but it is useless), therefore you must live with the 'Exiting due to
-signal SIGINT' message...
-
-The mouse driver is far from complete (lack of drawing, etc), but is enough to
-make almost all the demos work. Supports the CuteMouse WheelAPI.
-
-The timer is pretty versatile for it supports multiple timers with different
-frequencies. While not being the most accurate timer in the known universe, I
-think it's OK. Take this example: you have timer A with a very high rate, and
-then you have timer B with very low rate compared to A; now, A ticks OK, but
-timer B will probably loose precision!
-
-As an addition, stdout and stderr are redirected and dumped upon exit. This
-means that `printf' can be safely called during graphics. A bit of a hack, I
-know, because all messages come in bulk, but I think it's better than nothing.
-"Borrowed" from LIBRHUTI (Robert Hoehne).
-
-Window creating defaults: (0, 0, 300, 300), 16bpp. However, the video mode is
-chosen in such a way that first window will fit. If you need high resolution
-with small windows, set initial position far to the right (or way down); then
-you can move them back to any position right before the main loop.

-
-Environment variables:
-~~~~~~~~~~~~~~~~~~~~~~
- DMESA_NULDRV - (any value) force NUL driver
- GLUT_FPS - print frames/second statistics to stderr
- MESA_NO_SSE - (any value) safe option under pure DOS
- DMESA_GLUT_REFRESH - set vertical screen refresh rate (VESA3)
- DMESA_GLUT_BPP - set default bits per pixel (VGA needs 8)
- DMESA_GLUT_ALPHA - set default alpha bits (8)
- DMESA_GLUT_DEPTH - set default depth bits (16)
- DMESA_GLUT_STENCIL - set default stencil bits (8)
- DMESA_GLUT_ACCUM - set default accum bits (16)

-Mesa 3.0 for LynxOS builds in the following way:
-
-make lynxos
-
-This will build all the libraries and demo applications. You should have
-around 400 megabytes free for everything since everything is done with
-static
-libraries.
-
-Before using this make file however, you should perform the following
-actions:
-0) cd to the Mesa-3.0 directory
-1) Copy the GL directory under the include directory to /usr/include.
-2) Copy the files in the lib directory to /lib.
-3) Make links so that the Mesa libraries look like ordinary OpenGL
-libraries
-in /lib. This is important for compatibility with other OpenGL apps. This
-is done as follows:
-
-cd /lib
-ln -s libMesaGL.a libGL.a
-ln -s libMesaGLU.a libGLU.a
-
-Mesa 3.0 includes the GLUT (GL Utility Toolkit) by default.
-The demo applications are done using this toolkit.
-
-Mesa makefiles for building their apps could be used as well, but the
-following one is much more concise. Note that the order of the X libraries
-is important to the linker so that all symbols get resolved correctly.
-Changing the order may result in having to list a library twice to make
-sure all linkages are made correctly.

- Mesa 6.1 for MinGW32
- ~~~~~~~~~~~~~~~~~~~~
-
-
-
-Quick & dirty start:
---------------------
-
- mingw32-make -f Makefile.mgw [OPTIONS...]
-
- Look into the corresponding makefiles for further information.
- Check README.3DFX to find out how to compile Mesa Glide3 driver
- with MinGW32!

-
-*******************************************************************************
-The Mingw port for Mesa 3-D Graphics Library was created August 30, 1998 by Paul Garceau.
-
-Updated January 13, 2000; June 3, 2005 -- Paul Garceau <pgarceau@users.sourceforge.net>
-
-DISCLAIMER: I make this port of the Mesa 3-D Graphics Library as a service
-to the general public. I can, in no way support or make any guarantee that the
-build will work for your system.
-
-Acknowledgements:
-
- Daniel Borca, whose work and commitment to maintaining the Mingw port of the Mesa 3-D Graphics Library has been, and will continue to be greatly appreciated by an overworked and underpaid developer such as myself.
- Without the creative inspiration and personal commitment provided by Mumit Khan, Jan-Jaap Vanderhagen and Colin Peters, Mingw would never have existed. Acknowledgements also need to be given to all of the developers who have worked on Mingw, Mesa and Msys over the years.
- Last, but certainly far from the least, Brian Paul, who has dedicated at least the last seven or eight years of his life to making Mesa 3-D Graphics Library what it is today and managing the development for all of those years.
-*********************************************************************************
-
-Greetings,
-
- Feel free to modify or change things related to the Mingw build as you see fit, just remember that, the author of the current build may not be able to support any modifications you might want to make to the files which have been included for the build.
-
-Mesa core components are licensed under XFree-86 (for more on licensing of Mesa 3-D Graphics Library, check out the Mesa homepage (http://www.mesa3d.org).
-
-The Mingw generated libraries themselves are licensed under the GNU-LGPL license. Source code for Mingw can be found at http://www.mingw.org. For licensing terms on Mingw, please visit http://www.mingw.org.
-
- It is recommended that you use the latest "stable" release of Mingw. "Candidates" are beta testing distributions for Mingw. Mingw is available at http://www.mingw.org.
-
- This build has been tested under WinNT4/SP6. Win9x and WinNT5 remain untested by me. I have not tested any of the demos included with Mesa3d.
-
-Installation:
-
- This readme assumes that you already have extracted the necessary files to a working directory/folder that Mingw can use to build the Mesa3D libraries and that you know where that directory/folder is located on your Windows system. If you have any questions about how to set things up properly which is specific to Mesa3D, the folks on the Mesa3D mailing lists (http://www.mesa3d.org) would probably be happy to assist you. Also you can probably ask anyone on the Mingw mailing lists for any questions specific to Mingw (http://www.mingw.org)
-
-Targets and Environment variables used for Mingw build:
-
- Before going into the actual build of the libraries, here is a list of available targets for the make process:
-
- "all" or "libgl" -- this target will build libopengl.a, a static library. It will not build the demos, etc.
-
- clean -- this target will clean up most of the Mesa 3-D Graphics Library/object code from your hard drive.
-
- realclean -- this target will clean up all of the Mesa 3D Graphics Library and the Mesa object code that it can find.
-
- Environment Variables:
-
- The environment variables are used to determine what sort of graphics driver support needs to be included in the finished Mesa 3-D Graphics Library.
-
- GLIDE path to Glide3 SDK; used with FX.
- default = $(TOP)/glide3
- FX=1 build for 3dfx Glide3. Note that this disables
- compilation of most WMesa code and requires fxMesa.
- As a consequence, you'll need the Win32 Glide3
- library to build any application.
- default = no
- ICD=1 build the installable client driver interface
- (windows opengl driver interface)
- default = no
- X86=1 optimize for x86 (if possible, use MMX, SSE, 3DNow).
- default = no
-
-
-Running the Build:
-
- Launch Mingw.
- From the Windows Command Prompt:
- Set Environment Variables (as needed).
- "cd" to your Mesa3D 'root' directory.
- Enter "mingw32-make -f makefile.mgw <target>
-
- That's all there is to it.
-
- Enjoy!

-====================
-Updated on 2007-7-21
-====================
-
-Notice:
- 1) The generated DLLs are *not* compatible with the ones built
-with the other compilers like VC8, especially for GLUT.
-
- 2) Although more tests are needed, it can be used individually!
-
- 3) You can set the options about whether using STDCALL to build MESA. The
-config file is <Mesa3D-root>\configs\config.mgw. The default setting is that:
- ALL_USING_STDCALL = 1
-, which means using STDCALL to build MESA.
-
- 4) Of course, you can MESA without using STDCALL,I like this:)
-The setting is :
- ALL_USING_STDCALL = 0
-To do this, however, you must modify wingdi.h which is in MingW's include dir.
-For example, run:
- notepad C:\MingW\include\wingdi.h
-, and delete all the lines where all the wgl*() functions are. Because they would
-be conflicted with the ones in <Mesa3D-root>\include\GL\mesa_wgl.h.

-Updated on 2007-7-22
-====================
- I havn't thought that I would find a better way to solve my problems so soon.
-I changed the method in which the import-libs and DLLs are made. After this update,
-the DLLs of MESA are more optimized and more compatible.
- It seems that there is no need to keep the building way of 'NO-STDCALL'.The
-way of USING_STDCALL is so nice! The file <Mesa3D-root>\configs\config.mgw is
-also not needed, and can be deleted safely!

- Mesa 3.0 MITS Information
-
-
-This software is distributed under the terms of the GNU Library
-General Public License, see the LICENSE file for details.
-
-
-This document is a preliminary introduction to help you get
-started. For more detaile information consult the web page.
-
-http://10-dencies.zkm.de/~mesa/
-
-
-
-Version 0.1 (Yes it's very alpha code so be warned!)
-Contributors:
- Emil Briggs (briggs@bucky.physics.ncsu.edu)
- David Bucciarelli (tech.hmw@plus.it)
- Andreas Schiffler (schiffler@zkm.de)
-
-
-
-1. Requirements:
- Mesa 3.0.
- An SMP capable machine running Linux 2.x
- libpthread installed on your machine.
-
-
-2. What does MITS stand for?
- MITS stands for Mesa Internal Threading System. By adding
- internal threading to Mesa it should be possible to improve
- performance of OpenGL applications on SMP machines.
-
-
-3. Do applications have to be recoded to take advantage of MITS?
- No. The threading is internal to Mesa and transparent to
- applications.
-
-
-4. Will all applications benefit from the current implementation of MITS?
- No. This implementation splits the processing of the vertex buffer
- over two threads. There is a certain amount of overhead involved
- with the thread synchronization and if there is not enough work
- to be done the extra overhead outweighs any speedup from using
- dual processors. You will not for example see any speedup when
- running Quake because it uses GL_POLYGON and there is only one
- polygon for each vertex buffer processed. Test results on a
- dual 200 Mhz. Pentium Pro system show that one needs around
- 100-200 vertices in the vertex buffer before any there is any
- appreciable benefit from the threading.
-
-
-5. Are there any parameters that I can tune to try to improve performance.
- Yes. You can try to vary the size of the vertex buffer which is
- define in VB_MAX located in the file src/vb.h from your top level
- Mesa distribution. The number needs to be a multiple of 12 and
- the optimum value will probably depend on the capabilities of
- your machine and the particular application you are running.
-
-
-6. Are there any ways I can modify the application to improve its
- performance with the MITS?
- Yes. Try to use as many vertices between each Begin/End pair
- as possbile. This will reduce the thread synchronization
- overhead.
-
-
-7. What sort of speedups can I expect?
- On some benchmarks performance gains of up to 30% have been
- observerd. Others may see no gain at all and in a few rare
- cases even some degradation.
-
-
-8. What still needs to be done?
- Lots of testing and benchmarking.
- A portable implementation that works within the Mesa thread API.
- Threading of additional areas of Mesa to improve performance
- even more.
-
-
-
-Installation:
-
- 1. This assumes that you already have a working Mesa 3.0 installation
- from source.
- 2. Place the tarball MITS.tar.gz in your top level Mesa directory.
- 3. Unzip it and untar it. It will replace the following files in
- your Mesa source tree so back them up if you want to save them.
-
-
- README.MITS
- Make-config
- Makefile
- mklib.glide
- src/vbxform.c
- src/vb.h
-
- 4. Rebuild Mesa using the command
-
- make linux-386-glide-mits

- README for port of Mesa 3.x to XFree86 on OS/2 (X/2)
- (as of 19990514)
-
-
- Contents:
-
- 1) Binary release
- 2) Building from sources
- 3) History
- 4) Todo
- 5) Mesa Home Page
-
-
-1) Binary release
-
- Though the Mesa sources should build in a quite reasonable time even on
- a 585 class machine a binary relase is available (check topic 4) for an URL)
- This package includes:
-
- - lib/MesaGL.dll, MesaGL.a
- - lib/MesaGLU.dll, MesaGLU.a
- - lib/glut.dll, glut.a
- - include/GL/*.h
-
- Installing this in your XFree86 tree will enable you to build and
- run all applications compatible with Mesa (and the current DLL
- interface, of course ;-)
- As usual the OMF-style libraries can be created using emxomf.
- (e.g. "emxomf foo.a" creates the foo.lib omf-style library).
- The static libraries are rarely used and you have to rebuild
- Mesa to get them. They're a supported target, so you get
- them in a straightforward way (see below).
-
- The testing of these libraries was limited to the supplied
- demos/examples and a quite small number of third-party apps.
- No warranty ... as usual ... ;-)
-
-
-2) Instructions to build Mesa 3.x for XFree86/OS2 from sources:
-
- Except the official Mesa source distribution you need:
- - a recent version of XFree86 (3.3.x or above) including
- the programming libraries
- - EMX 0.9c (0.9d might work, never checked)
- - GNU make
- - REXX (!)
-
- The creation of the DLLs as well as of the static libraries
- (if you want to have them) is handled in "mklib-emx.cmd",
- a small REXX script. Perhaps not the best idea, but this
- way it fits best in the scheme used to build libraries
- on all platforms in Mesa 3.x.
-
- To actually build the libraries and demos, check mklib-emx.cmd
- and modify it as desired. Then type
- make os2-x11
- and wait for completion ;-)
-
-
-3) History
-
- Initially Darren Abbott (abbott@hiwaay.net) ported Mesa versions 2.x
- to XFree86 OS/2. This port might still be available from
- http://fly.HiWAAY.net/~abbott/xfree86-os2/xfree86.html
-
- The current port picked up things during the beta test for 3.0.
- No major changes in the source were done. The build mechanism under OS/2
- has been made very similar to other platforms (if you treat mklib-emx.cmd
- as a "black box").
- Advantage is that X/2 is now a valid target and all files are
- integrated in the official source distribution.
- Disadvantage is that this port (i.e. the DLLs' interface itself) is
- definitly NOT COMPATIBLE to those of version 2.x.
- It's uncertain whether this would be at all possible but since there
- a _very_ few those apps it's not worth to find out anyway.
- Also some libs (MesaTK, MesaAUX) are withdrawn from the Mesa distribution,
- and accordingly from the OS/2 port.
-
-4) Todo
-
- By now binary compatiblity is ensured by using the function names
- as entry points instead of ordinals. This might cost performance and
- is subject to change in future. In addition the supplied X86 assembler
- source is not used yet.
-
-5) Mesa Home Page
-
- You can get the source code and more information about Mesa from
- http://www.mesa3d.org/
-
- The OS/2 ports should be available from
- http://r350.ee.ntu.edu.tw/~hcchu/os2/ports

-This is a port of the GL and GLU libraries to NeXT/Apple object
-orientated systems. As these systems have their own window handling
-systems we simply use the offscreen rendering capability of Mesa
-to generate bitmaps which may then be displayed by the application
-with a View as required. Example pieces of code may be found in the
-OpenStep directory.
-
-Sadly there are now a proliferation of different system that we need to
-support compilation for: The original NextStep system, The OpenStep
-system, the Rhapsody/Mac OS X system and also the windows implementations
-of the latter two systems. This version of the code has been compiled and
-tested under the following architectures:
-
- NextStep 3.3
- OpenStep 4.2
- Rhapsody DR2
- WebObjects for NT 3.5
- WebObjects for NT 4.0
-
-All tests were done with Intel processors. Feedback on other systems would,
-however, be appreciated !
-
-On UNIX systems simply type "make openstep". Under Windows systems
-with WebObjects run the "win32-openstep.sh" script from within the Bourne
-shell provided with the development environment. In both cases this will
-build the libraries and place them into the "lib" directory. Some examples
-may be found in the OpenStep directory showing how to use the code in an
-actual application (MesaView) as well as some command line demos.
-
-The CC variable may be specified on the command line for doing such things
-as building FFAT libraries or using alternative compilers to the standard 'cc'
-e.g. make CC='cc -arch m68k -arch i386' openstep" will build the libraries
-with both intel and motorola architectures.

-Linux Quake
------------
-
-You can get Linux Quake from http://www.idsoftware.com/
-
-Quake I and II for Linux were tested with, and include, Mesa 2.6. You
-shouldn't have too many problems if you simply follow the instructions
-in the Quake distribution.
-
-
-
-RedHat 5.0 Linux problems
--------------------------
-
-RedHat Linux 5.x uses the GNU C library ("glibc" or "libc6") whereas
-previous RedHat and other Linux distributions use "libc5" for its
-runtime C library.
-
-Linux Quake I and II were compiled for libc5. If you compile Mesa
-on a RedHat 5.x system the resulting libMesaGL.so file will not work
-with Linux Quake because of the different C runtime libraries.
-The symptom of this is a segmentation fault soon after starting Quake.
-
-If you want to use a newer version of Mesa (like 3.x) with Quake on
-RedHat 5.x then read on.
-
-The solution to the C library problem is to force Mesa to use libc5.
-libc5 is in /usr/i486-linux-libc5/lib on RedHat 5.x systems.
-
-Emil Briggs (briggs@tick.physics.ncsu.edu) nicely gave me the following
-info:
-
-> I only know what works on a RedHat 5.0 distribution. RH5 includes
-> a full set of libraries for both libc5 and glibc. The loader ld.so
-> uses the libc5 libraries in /usr/i486-linux-libc5/lib for programs
-> linked against libc5 while it uses the glibc libraries in /lib and
-> /usr/lib for programs linked against glibc.
->
-> Anyway I changed line 41 of mklib.glide to
-> GLIDELIBS="-L/usr/local/glide/lib -lglide2x -L/usr/i486-linux-libc5/lib"
->
-> And I started quake2 up with a script like this
-> #!/bin/csh
-> setenv LD_LIBRARY_PATH /usr/i486-linux-libc5/lib
-> setenv MESA_GLX_FX f
-> ./quake2 +set vid_ref gl
-> kbd_mode -a
-> reset
-
-
-I've already patched the mklib.glide file. You'll have to start Quake
-with the script shown above though.

-
-Here's my thoughts on the problem. On a RH 5.x system, you can NOT build
-a libc5 executable or library. Red Hat just doesn't include the right
-stuff to do it.
-
-Since Quake is a libc5 based application, you are in trouble. You need
-libc5 libraries.
-
-What can you do about it? Well there's a package called gcc5 that does
-MOST of the right stuff to compile with libc5. (It brings back older
-header files, makes appropriate symbolic links for libraries, and sets
-up the compiler to use the correct directories) You can find gcc5 here:
-ftp://ecg.mit.edu/pub/linux/gcc5-1.0-1.i386.rpm
-
-No, this isn't quite enough. There are still a few tricks to getting
-Mesa to compile as a libc5 application. First you have to make sure that
-every compile uses gcc5 instead of gcc. Second, in some cases the link
-line actually lists -L/usr/lib which breaks gcc5 (because it forces you
-to use the glibc version of things)
-
-If you get all the stuff correctly compiled with gcc5 it should work.
-I've run Mesa 3.0B6 and its demos in a window with my Rush on a Red Hat
-5.1 system. It is a big hassle, but it can be done. I've only made Quake
-segfault, but I think that's from my libRush using the wrong libc.
-
-Yes, mixing libc5 and glibc is a major pain. I've been working to get
-all my libraries compiling correctly with this setup. Someone should
-make an RPM out of it and feed changes back to Brian once they get it
-all working. If no one else has done so by the time I get the rest of my
-stuff straightened out, I'll try to do it myself.

-Mesa Threads README
--------------------
-
-Thread safety was introduced in Mesa 2.6 by John Stone and
-Christoph Poliwoda.
-
-It was redesigned in Mesa 3.3 so that thread safety is
-supported by default (on systems which support threads,
-that is). There is no measurable penalty on single
-threaded applications.
-
-NOTE that the only _driver_ which is thread safe at this time
-is the OS/Mesa driver!
-
-
-At present the mthreads code supports three thread APIS:
- 1) POSIX threads (aka pthreads).
- 2) Solaris / Unix International threads.
- 3) Win32 threads (Win 95/NT).
-
-Support for other thread libraries can be added src/glthread.[ch]
-
-
-In order to guarantee proper operation, it is
-necessary for both Mesa and application code to use the same threads API.
-So, if your application uses Sun's thread API, then you should build Mesa
-using one of the targets for Sun threads.
-
-The mtdemos directory contains some example programs which use
-multiple threads to render to osmesa rendering context(s).
-
-Linux users should be aware that there exist many different POSIX
-threads packages. The best solution is the linuxthreads package
-(http://pauillac.inria.fr/~xleroy/linuxthreads/) as this package is the
-only one that really supports multiprocessor machines (AFAIK). See
-http://pauillac.inria.fr/~xleroy/linuxthreads/README for further
-information about the usage of linuxthreads.
-
-If you are interested in helping with thread safety work in Mesa
-join the Mesa developers mailing list and post your proposal.

-VMS support contributed by Jouk Jansen (joukj@hrem.stm.tudelft.nl)
-
-
-The latest version was tested on a VMSAlpha7.2 system using DECC6.0, but
-probably also works for other versions.
-
-At the moment only the libraries LIBMESGL.EXE/LIBMESGL.OLB,
-LIBMESAGLU.EXE/LIBMESAGLU.OLB and LIBGLUT.EXE/LIBGLUT.OLB and the demos of the
-directory [.DEMOS] can be build.
-However, feel free to create the missing "decrip.mms-files" in the other
-directories.
-
- The make files were tested
-using the DIGITAL make utility called MMS. There is also a public domain
-clone available (MMK) and I think, but it is not tested, that this
-utility will give (hardly) any problem.
-
-To make everything just type MMS (or MMK) in the main directory of
-mesagl. For MMS the deafult makefile is called descrip.mms, and
-that is what I have called it. I included alse some config files,
-all having mms somewhere in the name which all the makefiles need
-(just as your unix makefiles).
-
-On Alpha platforms at default a sharable images for the libraries are created.
-To get a static library make it by typing MMS/MACRO=(NOSHARE=1).
-On VAX platforms only static libraries can be build.
-
-23-sep-2005
-changed default compilation to use /float=ieee/ieee=denorm. The reason for
-this is that it makes Mesa on OpenVMS better compatible with other platforms
-and other packages for VMS that I maintain.
-For more information see
- http://nchrem.tnw.tudelft.nl/openvms
- https://bugs.freedesktop.org/show_bug.cgi?id=4270
-You may want to compile Mesa to use VAX-floating point arithmetic, instead
-of IEEE floating point by removing the /float=IEEE/denorm flag from the
-compiler options in the descrip.mms files.

-File: docs/README.WIN32
-
-Last updated: Apr 25, 2007 - Karl Schultz - kschultz@users.sourceforge.net
-
-Quick Start
------ -----
-
-Unzip the MesaLib, MesaGLUT, and MesaDemos ZIP files into the same
-directory. The libs and demos build separately, so if you do not care
-about the demos or GLUT, you only need to unzip MesaLib. If you unzip
-more than one ZIP file, they all need to be unzipped into the same
-directory. Don't worry, you will not overwrite anything.
-
-The Windows build system uses Microsoft Visual Studio. Project files
-for a specific version of Visual Studio are in their own directory in
-the top-level "windows" directory. For example, Visual Studio 8 files
-are in windows/VC8.
-
-Support has been dropped for versions of Visual Studio prior to 8. The
-main reason is because Microsoft now provides a free compiler and
-developer environment. Visual Studio Express can be found at
-
-http://msdn.microsoft.com/vstudio/express/visualc/default.aspx
-
-You'll also need the Platform SDK. Instructions for obtaining and
-using the SDK with Visual Studio Express can be found at
-
-http://msdn.microsoft.com/vstudio/express/visualc/usingpsdk/
-
-The project files to build the core Mesa library, Windows Mesa
-drivers, OSMesa, and GLU are in the mesa directory. The project files
-to build GLUT and some demo programs are in the progs directory.
-
-Makefiles are no longer shipped or supported, but can be generated
-from the projects using Visual Studio.
-
-
-Windows Drivers
-------- -------
-
-At this time, only the GDI driver is known to work. Most of the demos
-in progs/demos should work with this driver.
-
-Source code also exists in the tree for other drivers in
-src/mesa/drivers/windows, but the status of this code is unknown.
-
-The GDI driver operates basically by writing pixel spans into a DIB
-section and then blitting the DIB to the window. The driver was
-recently cleaned up and rewitten and so may have bugs or may be
-missing some functionality. The older versions of the CVS source may
-be useful in figuring out any problems, or report them to me.
-
-To build Mesa with the GDI driver, build the mesa, gdi, and glu
-projects in the Visual Studio workspace found at
-
- windows/VC8/mesa/mesa.sln
-
-The osmesa DLL can also be built with the osmesa project.
-
-The build system creates a lib top-level directory and copies
-resulting LIB and DLL files to this lib directory. The files are:
-
- OPENGL32.LIB, GLU32.LIB, OSMESA32.LIB
- OPENGL32.DLL, GLU32.DLL, OSMESA32.DLL
-
-If the MesaDemos ZIP file was extracted, the DLL files are also copied
-to the demos directory. This facilitates running the demos as described
-below.
-
-
-GLUT and Demos
----- --- -----
-
-A Visual Studio workspace can be found at
-
- windows/VC8/progs/progs.sln
-
-It can be used to build GLUT and a few demos. The GLUT lib and DLL
-are copied to the top-level lib directory, along with the Mesa libs.
-
-The demo build system expects to find the LIB files in the top level
-lib directory, so you must build the Mesa libs first. The demo
-executables are placed in the demos directory, because some of them
-rely on data files found there. Also, the Mesa lib DLL's were copied
-there by the Mesa lib build process. Therefore, you should be able to
-simply run the demo executables from the demo directory.
-
-If you want to run the demos from the Visual Studio, you may have to
-change the startup directory and explicitly state where the executables are.
-
-You may also build all the demo programs by using a makefile. Go to
-the progs/demos directory and make sure you have executed VCVARS32.BAT
-or whatever setup script is appropriate for your compiler. Then,
-
- nmake -f Makefile.win
-
-should build all the demos.
-
-
-Build System Notes
------ ------ -----
-
-VC8
----
-
-No notes.
-
-
-General
--------
-
-After building, you can copy the above DLL files to a place in your
-PATH such as $SystemRoot/SYSTEM32. If you don't like putting things
-in a system directory, place them in the same directory as the
-executable(s). Be careful about accidentially overwriting files of
-the same name in the SYSTEM32 directory.
-
-The DLL files are built so that the external entry points use the
-stdcall calling convention.
-
-Static LIB files are not built. The LIB files that are built with are
-the linker import files associated with the DLL files.
-
-The si-glu sources are used to build the GLU libs. This was done
-mainly to get the better tessellator code.
-
-To build "mangled" Mesa, add the preprocessor define USE_MGL_NAMESPACE
-to the project settings. You will also need to edit src/mesa.def to
-change all the gl* symbols to mgl*. Because this is easy to do with a
-global replace operation in a text editor, no additional mangled
-version of mesa.def is maintained or shipped.
-
-If you have a Windows-related build problem or question, it is
-probably better to direct it to me (kschultz@users.sourceforge.net),
-rather than directly to the other Mesa developers. I will help you as
-much as I can. I also monitor the Mesa mailing lists and will answer
-questions in this area there as well.

- WindML Driver for Mesa 4.0
-
-
-Requirements
-------------
-
-Tornado 2 + WindML, Cumulative Patchs are recommended.
-
-I suppose you have a valid WindML installation. Double buffer hardware
-gives better performance than double buffer software so if you can
-compile your WindML driver with this option, just do it. I/O
-redirection is adviced in target server.
-
-
-Tested on
----------
-
-During the development, my main target was a CoolMonster:
-- Video card: CT69000
-- CPU: PENTIUM 266MHz
-
-and my host a Windows NT + Tornado 2.
-
-
-Installation
-------------
-
-1. Mesa sources must be in root directory (C:\)
-
-2. Add the following line to your torVars.bat:
-set MESA_BASE=C:\Mesa
-
-OR copy the new torVars.bat in your bin path:
-c:/Mesa/src/ugl/tornado/torVars.sample ->
-/mnt/nt/Tornado/host/x86-win32/bin/torVars (for example)
-
-3. In a command prompt:
-$ torVars
-$ cd c:\Mesa
-$ make -f Makefile.ugl CPU=PENTIUM
-
-Take a long while...
-
-5. Include all the files from ugldemos folder to build some downloadable
- application modules
-
-4. Download UGL/Mesa object files on target
-
-For example via the WindShell:
-ld < c:\Tornado\target\lib\objMesaGL.o
-ld < c:\Tornado\target\lib\objMesaUGL.o
-ld < c:\Tornado\target\lib\objMesaGLU.o
-ld < c:\Tornado\target\lib\objGLUTshapes.o
-ld < c:\Tornado\target\lib\objMesaOS.o
-
-You can put the previous lines in a file and use:
-< filename
-
-6. Download the application modules.
-
-7. In WindShell, run:
--> uglalldemos
-
-During the show some messages will appear, it provides some useful
-information on key management.
-
-
-Coding
-------
-
-Sample Usage:
-
-In addition to the usual ugl calls to initialize UGL, (may be find an
-input driver), you must do the following to use the UGL/Mesa interface:
-
-1. Call uglMesaCreateContext() to create a UGL/Mesa rendering context,
- given the display format.
-
-2. Call uglMesaMakeCurrent() to bind the UGL/Mesa buffers to an
- UGL/Mesa Context and to make the context the current one.
-
-3. Make gl* calls to render your graphics.
-
-4. Use uglMesaSwapBuffers() when double buffering to swap front/back buffers.
-
-5. Before the UGL is destroyed, call MesaDestroyContext().
-
-6. Before exiting, call if required uglEventQDestroy and then
- uglDeinitialize();
-
-Limitations
------------
-
-I found the following limitations in my driver :
- - Color Indexed management is only in 8 bits
- - It's possible to mix UGL/OpenGL application with a software
- double buffer
-
-Modifications
-------------
-
-New files in Mesa:

- Mesa 3.1 release notes
-
- PLEASE READ!!!!
-
-
-New copyright
--------------
-
-Mesa 3.1 will be distributed under an XFree86-style copyright instead
-of the GNU LGPL.
-
-
-New directories
----------------
-
-All documentation files are now in the docs/ directory.
-All shell scripts are now in the bin/ directory.
-
-
-New library names
------------------
-
-Formerly, the main Mesa library was named libMesaGL.so (or libMesaGL.a)
-and the GLU library was named libMesaGLU.so (or libMesaGLU.a).
-
-Now, the main library is named libGL.so (or libGL.a) and the GLU library
-is named libGLU.so (or libGLU.a).
-
-The change allows Mesa to be more easily substituted for OpenGL.
-Specifically, the linker/loader on some Unix-like systems won't
-allow libMesaGL.so to be used instead of libGL.so if the application
-was linked with the former.
-
-Warning: if you have another OpenGL implementation installed on your
-system (i.e. you have another OpenGL libGL.so) you'll have to be
-carefull about which library (OpenGL or Mesa) you link against. Be
-aware of -L linker flags and the value of the LD_LIBRARY_PATH environment
-variable.
-
-
-New library versioning
-----------------------
-
-Previously, the Mesa GL library was named libMesaGL.so.3.0
-To better support Linux/OpenGL standards, the Mesa GL library is now
-named libGL.so.1.2.030100 This indicates version 1.2 of the OpenGL spec
-and Mesa implementation 3.1.0
-
-In the long term this will allow better interoperability with other
-OpenGL implementations, especially on Linux. In the short term,
-OpenGL apps may have to be relinked to use the new library naming.
-
-
-
-New makefiles
--------------
-
-The old Makefiles found in the various directories have been renamed
-to Makefile.X11 in order to prevent filename collisions with autoconfig-
-generated Makefiles.
-
-The top-level Makefile simply includes Makefile.X11
-If your top-level Makefile get's overwritten/destroyed you can restore
-it by copying Makefile.X11 to Makefile
-
-
-New extensions
---------------
-
-GL_EXT_stencil_wrap
- Implements two new stencil operations: GL_INCR_WRAP_EXT and
- GL_DECR_WRAP_EXT which allow stencil increment and decrement
- without clamping.
-
-GL_INGR_blend_func_separate
- Allows specification of blend factors for RGB and Alpha independently.
- (INGR = Intergraph)
-
-GL_ARB_multitexture
- Multiple simultaneous textures. (ARB = Architecture Review Board)
-
-GL_NV_texgen_reflection
- nVidia texgen extension for better reflection mapping.
-
-GL_PGI_misc_hints
- Assorted transformation hints.
-
-GL_EXT_compiled_vertex_array
- Compiled vertex arrays.
-
-GL_EXT_clip_volume_hint
- Allows one to disable clip volume (frustum) testing.
-
-
-
-Extensions removed
-------------------
-
-GL_EXT_multitexture - obsolete in favor of GL_ARB_multitexture
-
-
-
-Config file
------------
-
-By default, /etc/mesa.conf will be read when Mesa starts. This
-file controls default hints, enable/disable of extensions, and
-more. See the CONFIG file for documentation.
-
-
-
-Optimizations
--------------
-
-Keith Whitwell has contributed significant optimizations to Mesa's
-vertex transformation code. Basically, the whole transformation
-stage of Mesa has been rewritten.
-
-It's impossible to give a speedup factor. You'll just have to
-try your app and see how it performs.
-
-
-
-Device Driver changes
----------------------
-
-A bunch of new device driver functions have been added. See src/dd.h
-Keith Harrison contributed many of them. I've been planning on adding
-a bunch of functions like these to make writing hardware drivers easier.
-More such function will probably be added in the near future.
-
-
-
-Miscellaneous
--------------
-
-util/glstate.c has some handy functions for debugging. Basically, it
-offers a simple function for printing GL state variables. It's not
-finished yet. There's a LOT more GLenum records to be added (see the
-code). Anyone want to help?

-
-
-
-The Mesa 3.2.1 release mainly just fixes bugs since the 3.2 release.
-See the VERSIONS file for the exact list.

-
-GLU Polygon Tessellator
------------------------
-
-The GLU tessellator has been reverted back to the version included
-with Mesa 3.0 since it's more stable. The Mesa 3.1/3.2 tessellator
-implemented the GLU 1.3 specification but suffered from a number of
-bugs.
-
-Mesa implements GLU 1.1.
-
-Ideally, people should use the GLU 1.3 library included in SGI's
-OpenGL Sample Implementation (SI) available from
-http://oss.sgi.com/projects/ogl-sample/
-People are working to make easy-to-install Linux RPMs of the
-GLU library.

- Mesa 3.3 release notes
-
- July 21, 2000
-
- PLEASE READ!!!!
-
-
-
-Introduction
-------------
-
-Mesa uses an even/odd version number scheme like the Linux kernel.
-Odd numbered versions (such as 3.3) designate new developmental releases.
-Even numbered versions (such as 3.2.1) designate stable releases.
-
-Mesa 3.3 has a undergone many internal changes since version 3.2
-and features a lot of new extensions. 3.3 is expected to be pretty
-stable, but perhaps not as stable as 3.2 which has been used by
-thousands of users over the past months.
-
-Everyone is encouraged to try Mesa 3.3. Bugs should be reported to
-the Mesa bug database on www.sourceforge.net.
-
-
-
-Header file / GLenum changes
-----------------------------
-
-The gl.h and glu.h headers now use #defines to define all GL_* tokens
-instead of C-language enums. This change improves Mesa/OpenGL
-interoperability.
-
-
-
-New API dispatch code
----------------------
-
-The core Mesa gl* functions are now implemented with a new dispatch
-(jump table) which will allow simultaneous direct/indirect rendering.
-
-The code is found in the glapi*.[ch] files.
-
-Of interest: the actual "glFooBar" functions are generated with
-templatized code defined in glapitemp.h and included by glapi.c
-The glapitemp.h template should be reusable for all sorts of OpenGL
-projects.
-
-The new dispatch code has also optimized with x86 assembly code.
-This optimization eliminates copying the function arguments during
-dispatch.
-
-
-
-New thread support
-------------------
-
-Thread support in Mesa has been rewritten. The glthread.[ch] files
-replace mthreads.[ch]. Thread safety is always enabled (on platforms
-which support threads, that is). There is virtually no performance
-penalty for typical single-thread applications. See the glapi.c
-file for details.
-
-The Xlib driver (XMesa) is now thread-safe as well. Be sure to
-call XInitThreads() in your app first. See the xdemos/glthreads.c
-demo for an example.
-
-
-
-Make configuration changes
---------------------------
-
-If you use the old-style (non GNU automake) method to build Mesa note
-that several of the configuration names have changed:
-
- Old name New name
- ------------- ----------------
- linux-elf linux
- linux linux-static
- linux-386-elf linux-386
- linux-386 linux-386-static
- etc.
-
-
-
-New extensions
---------------
-
-GL_ARB_transpose_matrix
- Adds glLoadTransposeMatrixARB() and glMultTransposeMatrixARB()
- functions.
-
-GL_ARB_texture_cube_map
- For cube-based reflection mapping.
-
-GL_EXT_texture_add_env
- Adds GL_ADD texture environment mode.
- See http://www.berkelium.com/OpenGL/EXT/texture_env_add.txt
-
-GL_EXT_texture_lod_bias
- Allows mipmapped texture blurring and sharpening.
-
-GLX_EXT_visual_rating extension
- This extension has no effect in stand-alone Mesa (used for DRI).
-
-GL_HP_occlusion_test
- Used for bounding box occlusion testing (see demos/occlude.c).
-
-GL_SGIX_pixel_texture / GL_SGIS_pixel_texture
- Lets glDraw/CopyPixels draw a texture coordinate image.
-
-GL_SGI_color_matrix
- Adds a color matrix and another set of scale and bias parameters
- to the glDraw/CopyPixels paths.
-
-GL_SGI_color_table
- Adds additional color tables to the glDraw/Read/CopyPixels paths.
-
-GL_EXT_histogram
- Compute histograms for glDraw/Read/CopyPixels.
-
-GL_EXT_blend_func_separate
- This is the same as GL_INGR_blend_func_separate.
-
-GL_ARB_texture_cube_mapping
- 6-face cube mapping, nicer than sphere mapping
-
-GL_EXT_texture_env_combine
- For advanced texture environment effects.
-
-
-Documentation for all these functions can be found at
-http://oss.sgi.com/projects/ogl-sample/registry/
-
-
-
-GLX_SGI_make_current_read functionality
----------------------------------------
-
-The functionality of this extension is needed for GLX 1.3 (and required
-for the Linux/OpenGL standards base).
-
-Implementing this function required a **DEVICE DRIVER CHANGE**.
-The old SetBuffer() function has been replaced by SetReadBuffer() and
-SetDrawBuffer(). All device drivers will have to be updated because
-of this change.
-
-The new function, glXMakeContextCurrent(), in GLX 1.3 now works in Mesa.
-The xdemos/wincopy.c program demonstrates it.
-
-
-
-Image-related code changes
---------------------------
-
-The imaging path code used by glDrawPixels, glTexImage[123]D,
-glTexSubImage[123], etc has been rewritten. It's now faster,
-uses less memory and has several bug fixes. This work was
-actually started in Mesa 3.1 with the glTexImage paths but has now
-been carried over to glDrawPixels as well.
-
-
-
-Device driver interface changes
--------------------------------
-
-Added new functions for hardware stencil buffer support:
- WriteStencilSpan
- ReadStencilSpan
- WriteStencilPixels
- ReadStencilPixels
-
-
-Removed old depth buffer functions:
- AllocDepthBuffer
- DepthTestSpan
- DepthTestPixels
- ReadDepthSpanFloat
- ReadDepthSpanInt
-
-
-Added new depth buffer functions:
- WriteDepthSpan
- ReadDepthSpan
- WriteDepthPixels
- ReadDepthPixels
-
- These functions always read/write 32-bit GLuints. This will allow
- drivers to have anywhere from 0 to 32-bit Z buffers without
- recompiling for 16 vs 32 bits as was previously needed.
-
-
-New texture image functions
- The entire interface for texture image specification has been updated.
- With the new functions, it's optional for Mesa to keep an internal copy
- of all textures. Texture download should be a lot faster when the extra
- copy isn't made.
-
-Misc changes
- TexEnv now takes a target argument
- Removed UseGlobalTexturePalette (use Enable function instead)
-
-
-Also added
- ReadPixels
- CopyPixels
-
-
-The SetBufffer function has been replaced by SetDrawBuffer and
-SetReadBuffer functions. This lets core Mesa independently
-specify which buffer is to be used for reading and which for
-drawing.
-
-The Clear function's mask parameter has changed. Instead of
-mask being the flags specified by the user to glClear, the
-mask is now a bitmask of the DD_*_BIT flags in dd.h. Now
-multiple color buffers can be specified for clearing (ala
-glDrawBuffers). The driver's Clear function must also
-check the glColorMask glIndexMask, and glStencilMask settings
-and do the right thing. See the X/Mesa, OS/Mesa, or FX/Mesa
-drivers for examples.
-
-
-The depth buffer changes shouldn't be hard to make for existing
-drivers. In fact, it should simply the code. Be careful with
-the depthBits value passed to gl_create_context(). 1 is a bad
-value! It should normally be 0, 16, 24, or 32.
-
-
-gl_create_framebuffer() takes new arguments which explicitly tell
-core Mesa which ancillary buffers (depth, stencil, accum, alpha)
-should be implemented in software. Mesa hardware drivers should
-carefully set these flags depending on which buffers are in the
-graphics card.
-
-
-
-Internal constants
-------------------
-
-Point and line size range and granularity limits are now stored
-in the gl_constants struct, which is the Const member of GLcontext.
-The limits are initialized from values in config.h but may be
-overridden by device drivers to reflect the limits of that driver's
-hardware.
-
-Also added constants for NumAuxBuffers and SubPixelBits.
-
-
-
-OpenGL Conformance
-------------------
-
-Mesa now passes all the OpenGL 1.1 conformance tests, except for
-antialiased lines. AA lines fail on some, but not all, the tests.
-In order to fix the remaining failures, a new AA line algorithm will
-be needed (which computes coverage values for end-point fragments).
-This will be done for Mesa 3.5/3.6.
-
-
-
-OpenGL 1.2 GL_ARB_imaging subset
---------------------------------
-
-Mesa 3.3 implements all the features of GL_ARB_imaging except for
-image convolution. This will (hopefully) be done for Mesa 3.5/3.6.

- Mesa 3.5 release notes
-
- June 21, 2001
-
- PLEASE READ!!!!
-
-
-
-Introduction
-------------
-
-Mesa uses an even/odd version number scheme like the Linux kernel.
-Odd numbered versions (such as 3.5) designate new developmental releases.
-Even numbered versions (such as 3.4) designate stable releases.
-
-The biggest change in Mesa 3.5 is a complete overhaul of the source
-code in order to make it more modular. This was driven by the DRI
-hardware drivers. It simplifies the DRI drivers and opens the door
-to hardware transform/clip/lighting (TCL). Keith Whitwell can take
-the credit for that.
-
-
-
-Driver Support
---------------
-
-The device driver interface in Mesa 3.5 has changed a lot since Mesa 3.4
-Not all of the older Mesa drivers have been updated. Here's the status:
-
-Driver Status
----------------------- -----------
-XMesa (Xlib) updated
-OSMesa (off-screen) updated
-FX (3dfx Voodoo1/2) updated
-SVGA updated
-GGI not updated
-Windows/Win32 not updated
-DOS/DJGPP not updated
-BeOS not updated
-Allegro not updated
-D3D not updated
-DOS not updated
-
-We're looking for volunteers to update the remaining drivers. Please
-post to the Mesa3d-dev mailing list if you can help.
-
-
-
-GLU 1.3
--------
-
-Mesa 3.5 includes the SGI Sample Implementation (SI) GLU library.
-This version of GLU supports the GLU 1.3 specification. The old
-Mesa GLU library implemented the 1.1 specification. The SI GLU
-library should work much better.
-
-You'll need a C++ compiler to compile the SI GLU library. This may
-be a problem on some systems.
-
-
-
-New Extensions
---------------
-
-GL_EXT_convolution
- Adds image convolution to glRead/Copy/DrawPixels/TexImage.
-
-GL_ARB_imaging
- This is the optional imaging subset of OpenGL 1.2.
- It's the GL_EXT_convolution, GL_HP_convolution_border_modes,
- GL_EXT_histogram, GL_EXT_color_table, GL_EXT_color_subtable
- GL_EXT_blend_color, GL_EXT_blend_minmax, GL_EXT_blend_subtract
- and GL_SGI_color_matrix extensions all rolled together.
- This is supported in all software renderers but not in all
- hardware drivers (3dfx for example).
-
-GL_ARB_texture_compression
- This is supported in Mesa but only used by the 3dfx DRI drivers
- for Voodoo4 and later.
-
-GL_ARB_texture_env_add
- This is identical to GL_EXT_texture_env_add.
-
-GL_NV_blend_square
- Adds extra blend source and dest factors which allow squaring
- of color values.
-
-GL_EXT_fog_coord
- Allows specification of a per-vertex fog coordinate instead of
- having fog always computed from the eye distance.
-
-GL_EXT_secondary_color
- Allows specifying the secondary (specular) color for each vertex
- instead of getting it only from lighting in GL_SEPARATE_SPECULAR_COLOR
- mode.
-
-GL_ARB_texture_env_combine
- Basically the same as GL_EXT_texture_env_combine
-
-GL_ARB_texture_env_add extension
- Texture addition mode.
-
-GL_ARB_texture_env_dot3 extension
- Dot product texture environment.
-
-GL_ARB_texture_border_clamp
- Adds GL_CLAMP_TO_BORDER_ARB texture wrap mode
-
-GL_SGIX_depth_texture, GL_SGIX_shadow and GL_SGIX_shadow_ambient
- Implements a shadow casting algorithm based on depth map textures
-
-GL_SGIS_generate_mipmap
- Automatically generate lower mipmap images whenever the base mipmap
- image is changed with glTexImage, glCopyTexImage, etc.
-
-
-
-libOSMesa.so
-------------
-
-libOSMesa.so is a new library which contains the OSMesa interface for
-off-screen rendering. Apps which need the OSMesa interface should link
-with both -lOSMesa and -lGL. This change was made so that stand-alone
-Mesa works the same way as XFree86/DRI's libGL.
-
-
-
-Device Driver Changes / Core Mesa Changes
------------------------------------------
-
-The ctx->Driver.LogicOp() function has been removed. It used to
-be called during state update in order to determine if the driver
-could do glLogicOp() operations, and if not, set the SWLogicOpEnabled
-flag. Drivers should instead examine the LogicOp state themselves
-and choose specialized point, line, and triangle functions appropriately,
-or fall back to software rendering. The Xlib driver was the only driver
-to use this function. And since the Xlib driver no longer draws
-points, lines or triangles using Xlib, the LogicOp function isn't needed.
-
-The ctx->Driver.Dither() function has been removed. Drivers should
-detect dither enable/disable via ctx->Driver.Enable() instead.
-
-The ctx->Driver.IndexMask() and ctx->Driver.ColorMask() functions
-are now just called from glIndexMask and glColorMask like the other
-GL state-changing functions. They are no longer called from inside
-gl_update_state(). Also, they now return void. The change was made
-mostly for sake of uniformity.
-
-The NEW_DRVSTATE[0123] flags have been removed. They weren't being used
-and are obsolete w.r.t. the way state updates are done in DRI drivers.
-
-
-Removed obsolete gl_create_visual() and gl_destroy_visual().
-
-Renamed functions (new namespace):
-
-old new
-gl_create_framebuffer _mesa_create_framebuffer
-gl_destroy_framebuffer _mesa_destroy_framebuffer
-gl_create_context _mesa_create_context
-gl_destroy_context _mesa_destroy_context
-gl_context_initialize _mesa_context_initialize
-gl_copy_context _mesa_copy_context
-gl_make_current _mesa_make_current
-gl_make_current2 _mesa_make_current2
-gl_get_current_context _mesa_get_current_context
-gl_flush_vb _mesa_flush_vb
-gl_warning _mesa_warning
-gl_compile_error _mesa_compile_error
-
-
-All the drivers have been updated, but not all of them have been
-tested since I can't test some platforms (DOS, Windows, Allegro, etc).
-
-
-X/Mesa Driver
--------------
-
-The source files for the X/Mesa driver in src/X have been renamed.
-The xmesa[1234].c files are gone. The new files are xm_api.c,
-xm_dd.c, xm_line.c, xm_span.c and xm_tri.c.
-
-
-
-Multitexture
-------------
-
-Eight texture units are now supported by default.
-
-
-
-OpenGL SI related changes
--------------------------
-
-In an effort to make Mesa's internal interfaces more like the OpenGL
-SI interfaces, a number of changes have been made:
-
-1. Importing the SI's glcore.h file which defines a number of
-interface structures like __GLimports and __GLexports.
-
-2. Renamed "struct gl_context" to "struct __GLcontextRec".
-
-3. Added __glCoreCreateContext() and __glCoreNopDispatch() functions.
-
-4. The GLcontext member Visual is no longer a pointer.
-
-5. New file: imports.c to setup default import functions for Mesa.
-
-
-
-
-16-bit color channels
----------------------
-
-There's experimental support for 16-bit color channels (64-bit pixels)
-in Mesa 3.5. Only the OSMesa interface can be used for 16-bit rendering.
-Type "make linux-osmesa16" in the top-level directory to build the
-special libOSMesa16.so library.
-
-This hasn't been tested very thoroughly yet so please file bug reports
-if you have trouble.
-
-In the future I hope to implement support for 32-bit, floating point
-color channels.

- Mesa 4.0 release notes
-
- October 18, 2001
-
- PLEASE READ!!!!
-
-
-
-Introduction
-------------
-
-Mesa uses an even/odd version number scheme like the Linux kernel.
-Odd numbered versions (such as 3.3) designate new developmental releases.
-Even numbered versions (such as 3.4) designate stable releases.
-
-Mesa version 4.0 signifies two things:
-
- 1. A stabilization of the 3.5 development release
- 2. Implementation of the OpenGL 1.3 specification
-
-
-Note that the Mesa major version number is incremented with the OpenGL
-minor version number:
-
- Mesa 1.x == OpenGL 1.0
- Mesa 2.x == OpenGL 1.1
- Mesa 3.x == OpenGL 1.2
- Mesa 4.x == OpenGL 1.3
-
-
-
-New Features
-------------
-
-Mesa 3.5 already had all the new features of OpenGL 1.3, implemented as
-extensions. These extensions were simply promoted to standard features:
-
- GL_ARB_multisample
- GL_ARB_multitexture
- GL_ARB_texture_border_clamp
- GL_ARB_texture_compression
- GL_ARB_texture_cube_map
- GL_ARB_texture_env_add
- GL_ARB_texture_env_combine
- GL_ARB_texture_env_dot3
- GL_ARB_transpose_matrix
-
-In Mesa 4.0 the functions defined by these extensions are now available
-without the "ARB" suffix. For example, glLoadTransposeMatrixf() is now
-a standard API function. The new functions in OpenGL 1.3 and Mesa 4.0 are:
-
- glActiveTexture
- glClientActiveTexture
- glCompressedTexImage1D
- glCompressedTexImage2D
- glCompressedTexImage3D
- glCompressedTexSubImage1D
- glCompressedTexSubImage2D
- glCompressedTexSubImage3D
- glGetCompressedTexImage
- glLoadTransposeMatrixd
- glLoadTransposeMatrixf
- glMultiTexCoord1d
- glMultiTexCoord1dv
- glMultiTexCoord1f
- glMultiTexCoord1fv
- glMultiTexCoord1i
- glMultiTexCoord1iv
- glMultiTexCoord1s
- glMultiTexCoord1sv
- glMultiTexCoord2d
- glMultiTexCoord2dv
- glMultiTexCoord2f
- glMultiTexCoord2fv
- glMultiTexCoord2i
- glMultiTexCoord2iv
- glMultiTexCoord2s
- glMultiTexCoord2sv
- glMultiTexCoord3d
- glMultiTexCoord3dv
- glMultiTexCoord3f
- glMultiTexCoord3fv
- glMultiTexCoord3i
- glMultiTexCoord3iv
- glMultiTexCoord3s
- glMultiTexCoord3sv
- glMultiTexCoord4d
- glMultiTexCoord4dv
- glMultiTexCoord4f
- glMultiTexCoord4fv
- glMultiTexCoord4i
- glMultiTexCoord4iv
- glMultiTexCoord4s
- glMultiTexCoord4sv
- glMultTransposeMatrixd
- glMultTransposeMatrixf
- glSampleCoverage
- glSamplePass
-
-
-GLX 1.4 is the companion to OpenGL 1.3. The only new features in GLX 1.4
-are support for multisampling and the GLX_ARB_get_proc_address extension.
-glXGetProcAddress() is the only new function in GLX 1.4.
-
-
-
-Multisample and Texture Compression
------------------------------------
-
-The OpenGL 1.3 specification allows the multisample and texture compression
-features to essentially be no-ops. For example, if you query for multisample
-support you'll find none, but the API functions work.
-
-Similarly, texture compression is not implemented by any of the software
-drivers but you can specify a generic compressed texture format (like
-GL_COMPRESSED_RGBA) to glTexImage2D and it'll be accepted.
-
-
-
-Device Drivers
---------------
-
-Mesa advertises itself as either OpenGL 1.2 or OpenGL 1.3 depending on the
-device driver. If the driver enables all the ARB extensions which are part
-of OpenGL 1.3 then glGetString(GL_VERSION) will return "1.3". Otherwise,
-it'll return "1.2".
-
-A number of Mesa's software drivers haven't been actively maintained for
-some time. We rely on volunteers to maintain many of the drivers.
-Here's the current status of all included drivers:
-
-
-Driver Status
----------------------- ---------------------
-XMesa (Xlib) implements OpenGL 1.3
-OSMesa (off-screen) implements OpenGL 1.3
-FX (3dfx Voodoo1/2) implements OpenGL 1.3
-SVGA implements OpenGL 1.3
-Wind River UGL implements OpenGL 1.3
-Windows/Win32 implements OpenGL 1.3
-GGI needs updating
-DOS/DJGPP needs updating
-BeOS needs updating
-Allegro needs updating
-D3D needs updating
-DOS needs updating
-
-Special thanks go to Karl Schultz for updating the Windows driver.
-
-The XFree86/DRI drivers have not yet been updated to use Mesa 4.0 as of
-September 2001, but that should happen eventually.
-
-
-
-Other Changes
--------------
-
-See the VERSIONS file for more details about bug fixes, etc. in Mesa 4.0.

-Device Drivers
---------------
-
-Mesa advertises itself as either OpenGL 1.2 or OpenGL 1.3 depending on the
-device driver. If the driver enables all the ARB extensions which are part
-of OpenGL 1.3 then glGetString(GL_VERSION) will return "1.3". Otherwise,
-it'll return "1.2".
-
-A number of Mesa's software drivers haven't been actively maintained for
-some time. We rely on volunteers to maintain many of the drivers.
-Here's the current status of all included drivers:
-

- Mesa 4.1 release notes
-
- October 29, 2002
-
- PLEASE READ!!!!
-
-
-
-Introduction
-------------
-
-Mesa uses an even/odd version number scheme like the Linux kernel.
-Even numbered versions (such as 4.0) designate stable releases.
-Odd numbered versions (such as 4.1) designate new developmental releases.
-
-
-New Features in Mesa 4.1
-------------------------
-
-New extensions. Docs at http://oss.sgi.com/projects/ogl-sample/registry/
-
-GL_NV_vertex_program
-
- NVIDIA's vertex programming extension
-
-GL_NV_vertex_program1_1
-
- A few features built on top of GL_NV_vertex_program
-
-GL_ARB_window_pos
-
- This is the ARB-approved version of GL_MESA_window_pos
-
-GL_ARB_depth_texture
-
- This is the ARB-approved version of GL_SGIX_depth_texture.
- It allows depth (Z buffer) data to be stored in textures.
- This is used by GL_ARB_shadow
-
-GL_ARB_shadow
-
- Shadow mapping with depth textures.
- This is the ARB-approved version of GL_SGIX_shadow.
-
-GL_ARB_shadow_ambient
-
- Allows one to specify the luminance of shadowed pixels.
- This is the ARB-approved version of GL_SGIX_shadow_ambient.
-
-GL_EXT_shadow_funcs
-
- Extends the set of GL_ARB_shadow texture comparision functions to
- include all eight of standard OpenGL dept-test functions.
-
-GL_ARB_point_parameters
-
- This is basically the same as GL_EXT_point_parameters.
-
-GL_ARB_texture_env_crossbar
-
- Allows any texture combine stage to reference any texture source unit.
-
-GL_NV_point_sprite
-
- For rendering points as textured quads. Useful for particle effects.
-
-GL_NV_texture_rectangle (new in 4.0.4 actually)
-
- Allows one to use textures with sizes that are not powers of two.
- Note that mipmapping and several texture wrap modes are not allowed.
-
-GL_EXT_multi_draw_arrays
-
- Allows arrays of vertex arrays to be rendered with one call.
-
-GL_EXT_stencil_two_side
-
- Separate stencil modes for front and back-facing polygons.
-
-GLX_SGIX_fbconfig & GLX_SGIX_pbuffer
-
- Off-screen rendering support.
-
-GL_ATI_texture_mirror_once
-
- Adds two new texture wrap modes: GL_MIRROR_CLAMP_ATI and
- GL_MIRROR_CLAMP_TO_EDGE_ATI.
-
-
-
-Device Driver Status
---------------------
-
-A number of Mesa's software drivers haven't been actively maintained for
-some time. We rely on volunteers to maintain many of these drivers.
-Here's the current status of all included drivers:
-
-
-Driver Status
----------------------- ---------------------
-XMesa (Xlib) implements OpenGL 1.3
-OSMesa (off-screen) implements OpenGL 1.3
-FX (3dfx Voodoo1/2) implements OpenGL 1.3
-SVGA implements OpenGL 1.3
-Wind River UGL implements OpenGL 1.3
-Windows/Win32 implements OpenGL 1.3
-DOS/DJGPP implements OpenGL 1.3
-GGI implements OpenGL 1.3
-BeOS needs updating (underway)
-Allegro needs updating
-D3D needs updating
-DOS needs updating
-
-
-
-New features in GLUT
---------------------
-
-1. Frames per second printing
-
- GLUT now looks for an environment variable called "GLUT_FPS". If it's
- set, GLUT will print out a frames/second statistic to stderr when
- glutSwapBuffers() is called. By default, frames/second is computed
- and displayed once every 5 seconds. You can specify a different
- interval (in milliseconds) when you set the env var. For example
- 'export GLUT_FPS=1000' or 'setenv GLUT_FPS 1000' will set the interval
- to one second.
-
- NOTE: the demo or application must call the glutInit() function for
- this to work. Otherwise, the env var will be ignored.
-
- Finally, this feature may not be reliable in multi-window programs.
-
-
-2. glutGetProcAddress() function
-
- The new function:
-
- void *glutGetProcAddress(const char *procName)
-
- is a wrapper for glXGetProcAddressARB() and wglGetProcAddress(). It
- lets you dynamically get the address of an OpenGL function at runtime.
- The GLUT_API_VERSION has been bumped to 5, but I haven't bumped the
- GLUT version number from 3.7 since that's probably Mark Kilgard's role.
-
- This function should probably also be able to return the address of
- GLUT functions themselves, but it doesn't do that yet.
-
-
-
-XXX Things To Do Yet XXXX
--------------------------
-
-isosurf with vertex program exhibits some missing triangles (probably
-when recycling the vertex buffer for long prims).
-
-
-
-Porting Info
-------------
-
-If you're porting a DRI or other driver from Mesa 4.0.x to Mesa 4.1 here
-are some things to change:
-
-1. ctx->Texture._ReallyEnabled is obsolete.
-
- Since there are now 5 texture targets (1D, 2D, 3D, cube and rect) that
- left room for only 6 units (6*5 < 32) in this field.
- This field is being replaced by ctx->Texture._EnabledUnits which has one
- bit per texture unit. If the bit k of _EnabledUnits is set, that means
- ctx->Texture.Unit[k]._ReallyEnabled is non-zero. You'll have to look at
- ctx->Texture.Unit[k]._ReallyEnabled to learn if the 1D, 2D, 3D, cube or
- rect texture is enabled for unit k.
-
- This also means that the constants TEXTURE1_*, TEXTURE2_*, etc are
- obsolete.
-
- The tokens TEXTURE0_* have been replaced as well (since there's no
- significance to the "0" part:
-
- old token new token
- TEXTURE0_1D TEXTURE_1D_BIT
- TEXTURE0_2D TEXTURE_2D_BIT
- TEXTURE0_3D TEXTURE_3D_BIT
- TEXTURE0_CUBE TEXTURE_CUBE_BIT
- <none> TEXTURE_RECT_BIT
-
- These tokens are only used for the ctx->Texture.Unit[i].Enabled and
- ctx->Texture.Unit[i]._ReallyEnabled fields. Exactly 0 or 1 bits will
- be set in _ReallyEnabled at any time!
-
- Q: "What's the purpose of Unit[i].Enabled vs Unit[i]._ReallyEnabled?"
- A: The user can enable GL_TEXTURE_1D, GL_TEXTURE_2D, etc for any
- texure unit all at once (an unusual thing to do).
- OpenGL defines priorities that basically say GL_TEXTURE_2D has
- higher priority than GL_TEXTURE_1D, etc. Also, just because a
- texture target is enabled by the user doesn't mean we'll actually
- use that texture! If a texture object is incomplete (missing mip-
- map levels, etc) it's as if texturing is disabled for that target.
- The _ReallyEnabled field will have a bit set ONLY if the texture
- target is enabled and complete. This spares the driver writer from
- examining a _lot_ of GL state to determine which texture target is
- to be used.
-
-
-2. Tnl tokens changes
-
- During the implementation of GL_NV_vertex_program some of the vertex
- buffer code was changed. Specifically, the VERT_* bits defined in
- tnl/t_context.h have been renamed to better match the conventions of
- GL_NV_vertex_program. The old names are still present but obsolete.
- Drivers should use the newer names.
-
- For example: VERT_RGBA is now VERT_BIT_COLOR0 and
- VERT_SPEC_RGB is now VERT_BIT_COLOR1.
-
-
-
-3. Read/Draw Buffer changes
-
- The business of setting the current read/draw buffers in Mesa 4.0.x
- was complicated. It's much simpler now in Mesa 4.1.
-
- Here are the changes:
-
- - Renamed ctx->Color.DrawDestMask to ctx->Color._DrawDestMask
- - Removed ctx->Color.DriverDrawBuffer
- - Removed ctx->Pixel.DriverReadBuffer
- - Removed ctx->Color.MultiDrawBuffer
- - Removed ctx->Driver.SetDrawBuffer()
- - Removed swrast->Driver.SetReadBuffer().
- - Added ctx->Color._DrawDestMask - a bitmask of FRONT/BACK_LEFT/RIGHT_BIT
- values to indicate the current draw buffers.
- - Added ctx->Pixel._ReadSrcMask to indicate the source for pixel reading.
- The value is _one_ of the FRONT/BACK_LEFT/RIGHT_BIT values.
- - Added ctx->Driver.DrawBuffer() and ctx->Driver.ReadBuffer().
- These functions exactly correspond to glDrawBuffer and glReadBuffer calls.
- Many drivers will set ctx->Driver.DrawBuffer = _swrast_DrawBuffer and
- leave ctx->Draw.ReadBuffer NULL.
- DRI drivers should implement their own function for ctx->Driver.DrawBuffer
- and use it to set the current hardware drawing buffer. You'll probably
- also want to check for GL_FRONT_AND_BACK mode and fall back to software.
- Call _swrast_DrawBuffer() too, to update the swrast state.
- - Added swrast->Driver.SetBuffer().
- This function should be implemented by all device drivers that use swrast.
- Mesa will call it to specify the buffer to use for span reading AND
- writing and point/line/triangle rendering.
- There should be no confusion between current read or draw buffer anymore.
- - Added swrast->CurrentBuffer to indicate which color buffer to read/draw.
- Will be FRONT_LEFT_BIT, BACK_LEFT_BIT, FRONT_RIGHT_BIT or BACK_RIGHT_BIT.
- This value is usually passed to swrast->Driver.SetBuffer().
-
-
-4. _mesa_create_context() changes. This function now takes a pointer to
- a __GLimports object. The __GLimports structure contains function
- pointers to system functions like fprintf(), malloc(), etc.
- The _mesa_init_default_imports() function can be used to initialize
- a __GLimports object. Most device drivers (like the DRI drivers)
- should use this.
-
-
-5. In tnl's struct vertex_buffer, the field "ProjectedClipCoords"
- has been replaced by "NdcPtr" to better match the OpenGL spec's
- terminology.
-
-
-6. Since GL_EXT_stencil_two_side has been implemented, many of the
- ctx->Stencil fields are now 2-element arrays. For example,
- "GLenum Ref" is now "GLenum Ref[2]" The [0] elements are the front-face
- values and the [1] elements are the back-face values.
- ctx->Stencil.ActiveFace is 0 or 1 to indicate the current face for
- the glStencilOp/Func/Mask() functions.
- ctx->Stencil.TestTwoSide controls whether or not 1 or 2-sided stenciling
- is enabled.
-
-
-7. Removed ctx->Polygon._OffsetAny. Removed ctx->Polygon.OffsetMRD.
-
-
-8. GLfloat / GLchan changes:
-
- - Changed ctx->Driver.ClearColor() to take GLfloat[4] instead of GLchan[4].
- ctx->Color.ClearColor is now GLfloat[4] too.
- - Changed ctx->Driver.AlphaRef() to take GLfloat instead of GLchan.
- - ctx->Color.AlphaRef is now GLfloat.
- - texObj->BorderColor is now GLfloat[4]. texObj->_BorderChan is GLchan[4].
-
- This is part of an effort to remove all GLchan types from core Mesa so
- that someday we can support 8, 16 and 32-bit color channels dynamically
- at runtime, instead of at compile-time.
-
-
-9. GLboolean ctx->Tranform.ClipEnabled[MAX_CLIP_PLANES] has been replaced
- by GLuint ctx->Transform.ClipPlanesEnabled. The later is a bitfield.
-
-
-10. There's a new matrix_stack type in mtypes.h used for the Modelview,
- Projection, Color and Texcoord matrix stacks.
-
-
-11. The ctx->Current.* fields have changed a lot. Now, there's a
- ctx->Current.Attrib[] array for all vertex attributes which matches
- the NV vertex program conventions.

-bug fixes, etc. see the VERSIONS file.
-
-
-
-New Features in Mesa 5.0
-------------------------
-
-Mesa 5.0 supports OpenGL 1.4. Note Mesa's versioning convention:

- Mesa 5.1 release notes
-
- December 17, 2003
-
- PLEASE READ!!!!
-
-
-
-Introduction
-------------
-
-Mesa uses an even/odd version number scheme like the Linux kernel.
-Even-numbered versions (such as 5.0) designate stable releases.
-Odd-numbered versions (such as 5.1) designate new developmental releases.
-
-
-Bug fixes
----------
-See the VERSIONS file for a list of bugs fixed in this release.
-
-
-
-New Features in Mesa 5.1
-------------------------
-
-GL_ARB_vertex_program / GL_ARB_fragment_program
- Michal Krol and Karl Rasche implemented these extensions. Thanks!
- Be aware that there may be some rough edges and lurking bugs.
-
-GL_ATI_texture_env_combine3 extension
- This adds a few new texture combine modes.
- Contributed by Ian Romanick.
-
-GL_SGI_texture_color_table
- Adds a color table lookup to the RGBA texture path. There's a separate
- color table for each texture unit.
- Contributed by Eric Plante.
-
-GL_NV_fragment_program
- NVIDIA's fragment-level programming feature.
- Possible lurking bugs:
- - the DDX and DDY commands aren't fully tested
- - there may be bugs in the parser
- - the TEX and TXP instructions both do perspective correction
- - the pack/unpack instructions may not be correct
-
-GL_EXT_depth_bounds_test
- This extension adds a scissor-like test for the Z axis. It's used to
- optimize stencil-volume shadow algorithms.
-
-GL_NV_light_max_exponent
- Lifts the 128 limit for max light exponent.
-
-GL_EXT_texture_rectangle
- Identical to GL_NV_texture_rectangle
-
-GL_ARB_occlusion_query
- Useful for visibility-based culling.
-
-GL_ARB_texture_non_power_of_two
- Removes the restriction that texture dimensions must be powers of two.
-
-GL_ARB_vertex_buffer_object
- Allows server-side vertex arrays, optimized host/card data transfers, etc.
-
-GL_ARB_point_sprite
- ARB-approved version of GL_NV_point_sprite. Basically allows textures
- to be applied to points.
-
-GL_IBM_multimode_draw_arrays
- Allows multiple vertex arrays to be drawn with one call, including arrays
- of different types of primitives.
-
-GL_SUN_multi_draw_arrays
- An alias for GL_EXT_multi_draw_arrays, standard in OpenGL 1.4.
-
-Faster glDrawPixels / glCopyPixels in X11 driver
- If your X screen is 32bpp, glDrawPixels to the front color buffer will
- be accelerated (via XPutImage()) if the image format is GL_BGRA and the
- type is GL_UNSIGNED_BYTE. No raster operations, such as depth test,
- blend, fog, etc. can be enabled.
-
- If your X screen is 16bpp, glDrawPixels to the front color buffer will
- be accelerated (via XPutImage()) if the image format is GL_RGB and the
- type is GL_UNSIGNED_SHORT_5_6_5. No raster operations, such as depth
- test, blend, fog, etc. can be enabled.
-
- glCopyPixels() calls for the front color buffer will be accelerated
- (via XCopyArea()) if no raster operations, such as depth test, blend,
- fog, pixel zoom, etc. are enabled.
-
- The speed-up over typical software rendering is a factor of 10 for
- glDrawPixels and 100 for glCopyPixels.
-
-
-With the addition of GL_ARB_occlusion_query, GL_ARB_vertex_buffer_object,
-GL_ARB_texture_non_power_of_two and GL_EXT_shadow_funcs, Mesa 5.1 supports
-all the new features of OpenGL 1.5. Mesa 6.0 (the next stable release)
-will advertise GL_VERSION = "1.5".
-
-
-
-Vertex/Fragment program debugger
---------------------------------
-
-GL_MESA_program_debug is an experimental extension to support
-interactive debugging of vertex and fragment programs. See the
-docs/MESA_program_debug.spec file for details.
-
-The bulk of the vertex/fragment program debugger is implemented
-outside of Mesa. The GL_MESA_program_debug extension just has minimal
-hooks for stopping running programs and inspecting programs.
-
-The progs/tests/debugger.c (only in CVS) program is an example of how
-the extension can be used. Presently, the debugger code and demo code
-is in the same file. Eventually the debugger code should be moved
-into a reusable module.
-
-As it is now, the demo lets you set breakpoings in vertex/fragment
-programs, single step, and print intermediate register values. It's
-basically just a proof of concept.
-
-
-
-Directory tree reorganization
------------------------------
-
-The directory structure for Mesa has been overhauled to improve its layout.
-All source code for Mesa, GLU, GLUT, etc is now under the src/ directory
-in appropriate subdirectories.
-
-The Mesa source code and drivers has been reorganized under src/mesa/.
-
-All demonstration programs and tests are now in subdirectories under progs/.
-
-
-
-Build System Changes
---------------------
-
-The GNU automake/autoconf support has been removed. As it was, it seldom
-worked on anything but Linux. The Mesa developers aren't big fans of
-automake/autoconf/libtool and didn't have the time to maintain it.
-If someone wants to contribute new automake/autoconf support (and is
-willing to maintain it), it may be re-incorporated into Mesa, subject
-to some requirements.
-
-The "old style" makefile system has been updated:
- 1. Make-config has been trimmed down to fewer, modern configurations.
- 2. Most of the bin/mklib.* scripts have been rolled into a new "mklib"
- script that works on all sorts of systems. There are probably some
- bugs in it, but it's been tested on Linux, SunOS 5.8 and IRIX 6.5.
- Improvements/contributes are greatly appreciated.
- 3. The Makefile.X11 files have been cleaned up in various ways
-
-
-
-Source File Changes
--------------------
-
-The mmath.[ch] files are obsolete. Their contents have been moved
-into the imports.[ch] and macros.[ch] files.
-
-The files related to vertex and fragment programming have changed.
-Old files:
- vpexec.[ch]
- vpparse.[ch]
- vpstate.[ch]
-New files:
- program.[ch] - generic ARB/NV program code
- arbprogram.[ch] - ARB program API functions
- arbfragparse.[ch] - ARB fragment program parsing
- arbvertparse.[ch] - ARB vertex program parsing
- arbparse.[ch] - ARB vertex/fragment parsing

- tnl/t_save_loopback.c - new per-vertex code
- tnl/t_save_playback.c - new per-vertex code
- tnl/t_vtx_eval.c - old per-vertex code
-
-Other new files:
- bufferobj.[ch] - GL_ARB_vertex_buffer_object functions
- version.h - defines the Mesa version info
-
-Other removed files:
- swrast/s_histogram.[ch] - moved into src/histogram.c
-
-
-
-Other Changes
--------------
-
-The ctx->Driver.CreateTexture function has been removed - it wasn't used.
-
-New device driver hook functions:
- NewTextureObject - used to allocate struct gl_texture_objects
- NewTextureImage - used to allocate struct gl_texture_images
-
-New ctx->Texture._EnabledCoordUnits field:
- With the addition of GL_NV_fragment_program we may need to interpolate
- various sets of texture coordinates even when the corresponding texture
- unit is not enabled. That is, glEnable(GL_TEXTURE_xD) may never get
- called but we still may have to interpolate texture coordinates across
- triangles so that the fragment program will get them.
- This new field indicates which sets of texture coordinates are needed.
- If a bit is set in the ctx->Texture._EnabledUnits bitmask is set, the
- same bit MUST be set in ctx->Texture._EnabledCoordUnits.
-
-The ctx->_TriangleCaps field is deprecated.
- Instead of testing the DD_* bits in _TriangleCaps, you should instead
- directly test the relevant state variables, or use one of the helper
- functions like NEED_SECONDARY_COLOR() at the bottom of context.h
- While testing _TriangleCaps bits was fast, it was kludgey, and setting
- the bits in the first place could be error prone.
-
-New vertex processing code.
- The code behind glBegin, glEnd, glVertex, glNormal, etc. has been
- totally rewritten. It's a cleaner implementation now and should use
- less memory. (Keith)
-
-
-
-To Do
------
-Add screen-awareness to fakeglx.c
-
-
-
-
-Device Driver Status
---------------------
-
-A number of Mesa's software drivers haven't been actively maintained for
-some time. We rely on volunteers to maintain many of these drivers.
-Here's the current status of all included drivers:
-
-
-Driver Status
----------------------- ---------------------

- Mesa 6.0 release notes
-
- January 16, 2004
-
- PLEASE READ!!!!
-
-
-
-Introduction
-------------
-
-Mesa uses an even/odd version number scheme like the Linux kernel.
-Odd numbered versions (such as 5.1) designate new developmental releases.
-Even numbered versions (such as 6.0) designate stable releases.
-
-Mesa version 6.0 signifies two things:
-
- 1. A stabilization of the 5.1 development release
- 2. Implementation of the OpenGL 1.5 specification. When you query
- glGetString(GL_VERSION) "1.5" will be returned (as long as the
- driver supports all the required features).
-
-
-Note that the Mesa major version number is incremented with the OpenGL
-minor version number:
-
- Mesa 1.x == OpenGL 1.0
- Mesa 2.x == OpenGL 1.1
- Mesa 3.x == OpenGL 1.2
- Mesa 4.x == OpenGL 1.3
- Mesa 5.x == OpenGL 1.4
- Mesa 6.x == OpenGL 1.5
-
-
-
-New Features
-------------
-
-Mesa 5.1 already had all the new features of OpenGL 1.5, implemented as
-extensions. These extensions were simply promoted to standard features:
-
- GL_ARB_occlusion_query extension
- GL_ARB_texture_non_power_of_two extension
- GL_ARB_vertex_buffer_object extension
- GL_EXT_shadow_funcs
-
-
-
-Device Drivers
---------------
-
-Mesa advertises itself as either OpenGL 1.2 or OpenGL 1.3 depending on
-the device driver. For example, if the driver enables all the ARB
-extensions which are part of OpenGL 1.3 then glGetString(GL_VERSION)
-will return "1.3". Otherwise, it'll return "1.2".
-
-A number of Mesa's software drivers haven't been actively maintained for
-some time. We rely on volunteers to maintain many of the drivers.
-Here's the current status of all included drivers:

- Mesa 6.1 release notes
-
- August 18, 2004
-
- PLEASE READ!!!!
-
-
-
-Introduction
-------------
-
-Mesa uses an even/odd version number scheme like the Linux kernel.
-Odd numbered versions (such as 6.1) designate new developmental releases.
-Even numbered versions (such as 6.0) designate stable releases.
-
-
-New Features
-------------
-
-Half-precision floating point (GLhalf) pixel formats are supported
-in Mesa, but the feature isn't exposed yet since the ARB extension
-hasn't been finalized yet.
-
-
-Texture image handling
-----------------------
-
-The code which implements image conversion, pixel transfer ops, etc
-for glTexImage commands has been rewritten.
-
-Now the gl_texture_format struct has a new StoreImage function
-pointer. Each texture format must implement this function. The
-function is totally responsible for converting the user's texture
-image into the specific format. A few helper functions makes this
-relatively simple.
-
-Overall, the code is much simpler, cleaner and easier to work with
-now. Adding new texture formats is straight-forward and there's no
-longer any distinction between "hardware" and "software" formats.
-
-Finally, the code for compressed texture images has been reorganized
-as well.
-
-Removed files:
- texutil.c
- texutil.h
- texutil_tmp.h
-
-New files:
- texcompress_s3tc.c
- texcompress_fxt1.c
-
-
-
-Driver / context changes
-------------------------
-
-The _mesa_create_context() and _mesa_initialize_context() function
-parameters have changed. They now take a pointer to a struct
-dd_function_table. Drivers can initialize this table by calling
-_mesa_init_driver_functions(). Drivers should then plug in the special
-functions they implement. In particular, the ctx->Driver.NewTextureObject
-pointer _must_ be set so that the default texture objects created in
-_mesa_create/initialize_context() are correctly built.
-
-The _mesa_init_driver_functions() function allows a lot of redundant code
-to be removed from the device drivers (such as initializing
-ctx->Driver.Accum to point to _swrast_Accum). Adding new functions to
-the dd_function_table can be done with less hassle since the pointer can
-be initialized in _mesa_init_driver_functions() rather than in _all_ the
-drivers.
-
-
-Device Drivers
---------------
-
-Mesa advertises itself as supporting OpenGL 1.2, 1.3, 1.4 or 1.5
-depending on the device driver's capabilities. For example, if the
-driver enables all the ARB extensions which are part of OpenGL 1.5
-then glGetString(GL_VERSION) will return "1.5". Otherwise, it'll
-return "1.4" or the next lower version that implements all required
-functionality.

- Mesa 6.3 release notes
-
- July 20, 2005
-
- PLEASE READ!!!!
-
-
-
-Introduction
-------------
-
-Mesa uses an even/odd version number scheme like the Linux kernel.
-Odd numbered versions (such as 6.3) designate new developmental releases.
-Even numbered versions (such as 6.2) designate stable releases.
-
-
-
-New Features
-------------
-
-GL_ARB_draw_buffers - allows a fragment program to write to a number of
- separate color buffers, instead of just one.
-
-GL_OES_read_format - allows one to query the fastest glReadPixels format
- and datatype.
-
-GL_ARB_pixel_buffer_object - buffer objects for pixel read/write functions.
-
-GL_EXT_framebuffer_object - allows render-to-texture and provides a
- window-system indepedent Pbuffer facility.
- The Mesa CVS tree contains a couple tests of this extension.
-
-DirectFB driver, contributed by Claudio Ciccani. See docs/README.directfb
-for details.
-
-
-
-Vertex/Fragment Program PRINT Instruction
------------------------------------------
-
-The GL_NV_vertex_program and GL_NV_fragment_program languages have been
-extended with a PRINT instruction.
-
-
-
-glDeleteTextures(), glDeletePrograms() and glDeleteBuffers() Changed
---------------------------------------------------------------------
-
-To match the behaviour of other OpenGL implementations, glDeleteTextures,
-glDeletePrograms and glDeleteBuffers have been modified so that:
-
- * The named texture/program/buffer ID is immediately freed for re-use.
-
- * The actual texture object, program or buffers isn't really deleted until
- it is no longer bound in any rendering context (the reference count
- is zero).
-
-Previously, the texture/program/buffer ID wasn't freed until the object
-was really deleted.
-
-Note that textures, programs and buffers can be shared by several rendering
-contexts so they can't be deleted until they're unbound in _all_ contexts.
-
-
-
-GL_EXT_framebuffer_object changes
----------------------------------
-
-Implementing this extension involved changing a lot of code (for the better).
-
-The gl_framebuffer object now a collection of gl_renderbuffer objects.
-Renderbuffers may store colors, stencil indices, or depth values. The
-gl_framebuffer and gl_renderbuffer types are object-oriented in design.
-
-All the old RGB, color index, stencil and depth-related span functions for
-reading/writing pixels from/to buffers has changed. Now, all pixels are
-read/written through a set of common renderbuffer functions (methods).
-
-Most device drivers have been updated for these changes, but some haven't.
-
-
-
-To Do (someday) items
----------------------
- Switch to freeglut
- Increase MAX_DRAWBUFFERS
- driver hooks for BeginQuery/EndQuery
-
-
-
-Miscellaneous
--------------
-
-The main/get.c file is now generated with a Python script (get_gen.py).

-<h2>1. Basic Usage</h2>
-
-<p>
-The autoconf generated configure script can be used to guess your
-platform and change various options for building Mesa. To use the
-configure script, type:
-</p>
-
-<pre>
- ./configure
-</pre>
-
-<p>
-To see a short description of all the options, type <code>./configure
---help</code>. If you are using a development snapshot and the configure
-script does not exist, type <code>./autogen.sh</code> to generate it
-first. If you know the options you want to pass to
-<code>configure</code>, you can pass them to <code>autogen.sh</code>. It
-will run <code>configure</code> with these options after it is
-generated. Once you have run <code>configure</code> and set the options
-to your preference, type:
-</p>
-
-<pre>
- make
-</pre>
-
-<p>
-This will produce libGL.so and several other libraries depending on the
-options you have chosen. Later, if you want to rebuild for a different
-configuration run <code>make realclean</code> before rebuilding.
-</p>
-
-<p>
-Some of the generic autoconf options are used with Mesa:
-
-<ul>
-<li><code>--prefix=PREFIX</code> - This is the root directory where
-files will be installed by <code>make install</code>. The default is
-<code>/usr/local</code>.
-</li>
-<li><code>--exec-prefix=EPREFIX</code> - This is the root directory
-where architecture-dependent files will be installed. In Mesa, this is
-only used to derive the directory for the libraries. The default is
-<code>${prefix}</code>.
-</li>
-<li><code>--libdir=LIBDIR</code> - This option specifies the directory
-where the GL libraries will be installed. The default is
-<code>${exec_prefix}/lib</code>. It also serves as the name of the
-library staging area in the source tree. For instance, if the option
-<code>--libdir=/usr/local/lib64</code> is used, the libraries will be
-created in a <code>lib64</code> directory at the top of the Mesa source
-tree.
-</li>
-<li><code>--enable-static, --disable-shared</code> - By default, Mesa
-will build shared libraries. Either of these options will force static
-libraries to be built. It is not currently possible to build static and
-shared libraries in a single pass.
-</li>
-<li><code>CC, CFLAGS, CXX, CXXFLAGS</code> - These environment variables
-control the C and C++ compilers used during the build. By default,
-<code>gcc</code> and <code>g++</code> are used with the options
-<code>"-g -O2"</code>.
-</li>
-<li><code>LDFLAGS</code> - An environment variable specifying flags to
-pass when linking programs. These are normally empty, but can be used
-to direct the linker to use libraries in nonstandard directories. For
-example, <code>LDFLAGS="-L/usr/X11R6/lib"</code>.
-</li>
-<li><code>PKG_CONFIG_PATH</code> - When available, the
-<code>pkg-config</code> utility is used to search for external libraries
-on the system. This environment variable is used to control the search
-path for <code>pkg-config</code>. For instance, setting
-<code>PKG_CONFIG_PATH=/usr/X11R6/lib/pkgconfig</code> will search for
-package metadata in <code>/usr/X11R6</code> before the standard
-directories.
-</li>
-</ul>
-</p>
-
-<p>
-There are also a few general options for altering the Mesa build:
-<ul>
-<li><code>--with-x</code> - When the X11 development libraries are
-needed, the <code>pkg-config</code> utility <a href="#pkg-config">will
-be used</a> for locating them. If they cannot be found through
-<code>pkg-config</code> a fallback routing using <code>imake</code> will
-be used. In this case, the <code>--with-x</code>,
-<code>--x-includes</code> and <code>--x-libraries</code> options can
-control the use of X for Mesa.
-</li>
-<li><code>--enable-gl-osmesa</code> - The <a href="osmesa.html">OSMesa
-library</a> can be built on top of libGL for drivers that provide it.
-This option controls whether to build libOSMesa. By default, this is
-enabled for the Xlib driver and disabled otherwise. Note that this
-option is different than using OSMesa as the driver.
-</li>
-<li><code>--enable-debug</code> - This option will enable compiler
-options and macros to aid in debugging the Mesa libraries.
-</li>
-<li><code>--disable-asm</code> - There are assembly routines
-available for a few architectures. These will be used by default if
-one of these architectures is detected. This option ensures that
-assembly will not be used.
-</li>
-<li><code>--enable-32-bit, --enable-64-bit</code> - By default, the
-build will compile code as directed by the environment variables
-<code>CC</code>, <code>CFLAGS</code>, etc. If the compiler is
-<code>gcc</code>, these options offer a helper to add the compiler flags
-to force 32- or 64-bit code generation as used on the x86 and x86_64
-architectures.
-</li>
-</ul>
-</p>
-
-
-<a name="driver">
-<h2>2. Driver Options</h2>
-
-<p>
-There are several different driver modes that Mesa can use. These are
-described in more detail in the <a href="install.html">basic
-installation instructions</a>. The Mesa driver is controlled through the
-configure option --with-driver. There are currently three supported
-options in the configure script.
-</p>
-
-<ul>
-
-<a name="xlib">
-<li><b><em>Xlib</em></b> - This is the default mode for building Mesa.
-It uses Xlib as a software renderer to do all rendering. It corresponds
-to the option <code>--with-driver=xlib</code>. The libX11 and libXext
-libraries, as well as the X11 development headers, will be need to
-support the Xlib driver.
-</li>
-
-<a name="dri">
-<li><b><em>DRI</em></b> - This mode uses the DRI hardware drivers for
-accelerated OpenGL rendering. Enable the DRI drivers with the option
-<code>--with-driver=dri</code>. See the <a href="install.html">basic
-installation instructions</a> for details on prerequisites for the DRI
-drivers.
-</li>
-
-<!-- DRI specific options -->
-<p>
-<ul>
-<li><code>--with-dri-driverdir=DIR</code> - This option specifies the
-location the DRI drivers will be installed to and the location libGL
-will search for DRI drivers. The default is <code>${libdir}/dri</code>.
-</li>
-<li><code>--with-dri-drivers=DRIVER,DRIVER,...</code> - This option
-allows a specific set of DRI drivers to be built. For example,
-<code>--with-dri-drivers="swrast,i965,radeon,nouveau"</code>. By
-default, the drivers will be chosen depending on the target platform.
-See the directory <code>src/mesa/drivers/dri</code> in the source tree
-for available drivers. Beware that the swrast DRI driver is used by both
-libGL and the X.Org xserver GLX module to do software rendering, so you
-may run into problems if it is not available.</li>
-<!-- This explanation might be totally bogus. Kristian? -->
-<li><code>--disable-driglx-direct</code> - Disable direct rendering in
-GLX. Normally, direct hardware rendering through the DRI drivers and
-indirect software rendering are enabled in GLX. This option disables
-direct rendering entirely. It can be useful on architectures where
-kernel DRM modules are not available.
-</li>
-<li><code>--enable-glx-tls</code> - Enable Thread Local Storage (TLS) in
-GLX.
-</li>
-<li><code>--with-expat=DIR</code> - The DRI-enabled libGL uses expat to
-parse the DRI configuration files in <code>/etc/drirc</code> and
-<code>~/.drirc</code>. This option allows a specific expat installation
-to be used. For example, <code>--with-expat=/usr/local</code> will
-search for expat headers and libraries in <code>/usr/local/include</code>
-and <code>/usr/local/lib</code>, respectively.
-</li>
-</ul>
-</p>
-
-<a name="osmesa">
-<li><b><em>OSMesa</em></b> - No libGL is built in this
-mode. Instead, the driver code is built into the Off-Screen Mesa
-(OSMesa) library. See the <a href="osmesa.html">Off-Screen Rendering</a>
-page for more details.
-</li>
-
-<!-- OSMesa specific options -->
-<p>
-<ul>
-<li><code>--with-osmesa-bits=BITS</code> - This option allows the size
-of the color channel in bits to be specified. By default, an 8-bit
-channel will be used, and the driver will be named libOSMesa. Other
-options are 16- and 32-bit color channels, which will add the bit size
-to the library name. For example, <code>--with-osmesa-bits=16</code>
-will create the libOSMesa16 library with a 16-bit color channel.
-</li>
-</ul>
-</p>
-
-</ul>
-
-
-<a name="library">
-<h2>3. Library Options</h2>
-
-<p>
-The configure script provides more fine grained control over the GL
-libraries that will be built. More details on the specific GL libraries
-can be found in the <a href="install.html">basic installation
-instructions</a>.
-
-<ul>
-<a name="glu">
-<li><b><em>GLU</em></b> - The libGLU library will be built by default
-on all drivers. This can be disable with the option
-<code>--disable-glu</code>.
-</li>
-
-<a name="glw">
-<li><b><em>GLw</em></b> - The libGLw library will be built by default
-if libGLU has been enabled. This can be disable with the option
-<code>--disable-glw</code>.
-</li>
-
-<a name="glut">

-<h2>4. Demo Program Options</h2>
-
-<p>
-There are many demonstration programs in the MesaDemos tarball. If the
-programs are available when <code>./configure</code> is run, a subset of
-the programs will be built depending on the driver and library options
-chosen. See the directory <code>progs</code> for the full set of demos.
-
-<ul>
-<li><code>--with-demos=DEMOS,DEMOS,...</code> - This option allows a
-specific set of demo programs to be built. For example,
-<code>--with-demos="xdemos,slang"</code>. Beware that if this option is
-used, it will not be ensured that the necessary GL libraries will be
-available.
-</li>
-<li><code>--without-demos</code> - This completely disables building the
-demo programs. It is equivalent to <code>--with-demos=no</code>.

-<H1>Bug Database</H1>
-
-<p>
-The Mesa bug database is hosted on
-<a href="http://freedesktop.org" target="_parent">freedesktop.org</a>.
-The old bug database on SourceForge is no longer used.
-</p>
-
-<p>
-To file a Mesa bug, go to
-<a href="https://bugs.freedesktop.org/enter_bug.cgi?product=Mesa"
-target="_parent">
-Bugzilla on freedesktop.org</a>
-</p>
-
-<p>
-Please follow these bug reporting guidelines:
-</p>
-
-<ul>
-<li>Check if a new version of Mesa is available which might have fixed
-the problem.
-<li>Check if your bug is already reported in the database.
-<li>Monitor your bug report for requests for additional information, etc.
-<li>If you're reporting a crash, try to use your debugger (gdb) to get a stack
-trace. Also, recompile Mesa in debug mode to get more detailed information.
-<li>Describe in detail how to reproduce the bug, especially with games
-and applications that the Mesa developers might not be familiar with.
-<li>Provide a simple GLUT-based test program if possible
-</ul>
-
-<p>
-Bug reports will automatically be forwarded by bugzilla to the Mesa
-developer's mailing list.
-</p>
-
-<p>
-The easier a bug is to reproduce, the sooner it will be fixed.
-Please do everything you can to facilitate quickly fixing bugs.
-If your bug report is vague or your test program doesn't compile
-easily, the problem may not be fixed very quickly.

-<H1>Mesa/Gallium Cell Driver</H1>
-
-<p>
-The Mesa
-<a href="http://en.wikipedia.org/wiki/Cell_%28microprocessor%29" target="_parent">Cell</a>
-driver is part of the
-<a href="http://wiki.freedesktop.org/wiki/Software/gallium" target="_parent">Gallium3D</a>
-architecture.
-Tungsten Graphics did the original implementation of the Cell driver.
-</p>
-
-
-<H2>Source Code</H2>
-
-<p>
-The latest Cell driver source code is on the master branch of the Mesa
-git repository.
-</p>
-<p>
-To build the driver you'll need the IBM Cell SDK (version 2.1 or 3.0).
-To use the driver you'll need a Cell system, such as a PS3 running Linux,
-or the Cell Simulator (untested, though).
-</p>
-
-<p>
-If using Cell SDK 2.1, see the configs/linux-cell file for some
-special changes.
-</p>
-
-<p>
-To compile the code, run <code>make linux-cell</code>.
-Or to build in debug mode, run <code>make linux-cell-debug</code>.
-</p>
-
-<p>
-To use the library, make sure your current directory is the top of the
-Mesa tree, then set <code>LD_LIBRARY_PATH</code> like this:
-<pre>
- export LD_LIBRARY_PATH=$PWD/lib/gallium:$PWD/lib/
-</pre>
-
-<p>
-Verify that the Cell driver is being used by running
-<code>progs/xdemos/glxinfo</code> and looking for:
-<pre>
- OpenGL renderer string: Gallium 0.3, Cell on Xlib
-</pre>
-
-
-<H2>Driver Implementation Summary</H2>
-
-<p>
-Rasterization is parallelized across the SPUs in a tiled-based manner.
-Batches of transformed triangles are sent to the SPUs (actually, pulled by from
-main memory by the SPUs).
-Each SPU loops over a set of 32x32-pixel screen tiles, rendering the triangles
-into each tile.
-Because of the limited SPU memory, framebuffer tiles are paged in/out of
-SPU local store as needed.
-Similarly, textures are tiled and brought into local store as needed.
-</p>
-
-
-<H2>Status</H2>
-
-<p>
-As of October 2008, the driver runs quite a few OpenGL demos.
-Features that work include:
-</p>
-<ul>
-<li>Point/line/triangle rendering, glDrawPixels
-<li>2D, NPOT and cube texture maps with nearest/linear/mipmap filtering
-<li>Dynamic SPU code generation for fragment shaders, but not complete
-<li>Dynamic SPU code generation for fragment ops (blend, Z-test, etc), but not complete
-<li>Dynamic PPU/PPC code generation for vertex shaders, but not complete
-</ul>
-<p>
-Performance has recently improved with the addition of PPC code generation
-for vertex shaders, but the code quality isn't too great yet.
-</p>
-<p>
-Another bottleneck is SwapBuffers. It may be the limiting factor for
-many simple GL tests.
-</p>
-
-
-
-<H2>Debug Options</H2>
-
-<p>
-The CELL_DEBUG env var can be set to a comma-separated list of one or
-more of the following debug options:
-</p>
-<ul>
-<li><b>checker</b> - use a different background clear color for each SPU.
- This lets you see which SPU is rendering which screen tiles.
-<li><b>sync</b> - wait/synchronize after each DMA transfer
-<li><b>asm</b> - print generated SPU assembly code to stdout
-<li><b>fragops</b> - emit fragment ops debug messages
-<li><b>fragopfallback</b> - don't use codegen for fragment ops
-<li><b>cmd</b> - print SPU commands as their received
-<li><b>cache</b> - print texture cache statistics when program exits
-</ul>
-<p>
-Note that some of these options may only work for linux-cell-debug builds.
-</p>
-
-<p>
-If the GALLIUM_NOPPC env var is set, PPC code generation will not be used
-and vertex shaders will be run with the TGSI interpreter.
-</p>
-<p>
-If the GALLIUM_NOCELL env var is set, the softpipe driver will be used
-intead of the Cell driver.
-This is useful for comparison/validation.
-</p>
-
-
-
-<H2>Contributing</H2>
-
-<p>
-If you're interested in contributing to the effort, familiarize yourself
-with the code, join the <a href="lists.html">mesa3d-dev mailing list</a>,
-and describe what you'd like to do.

-<H1>Conformance</H1>
-
-<p>
-The SGI OpenGL conformance tests verify correct operation of OpenGL
-implementations. I, Brian Paul, have been given a copy of the tests
-for testing Mesa. The tests are not publically available.
-</p>
-<p>
-This file has the latest results of testing Mesa with the OpenGL 1.2
-conformance tests. Testing with the preliminary OpenGL 1.3 tests has
-also been done. Mesa passes all the 1.3 tests.
-</p>
-<p>
-The tests were run using the software X11 device driver on 24-bpp
-and 16-bpp displays.
-</p>
-<p>
-Mesa 4.0 and later pass all conformance tests at all path levels.
-Note that this says nothing about the conformance of hardware drivers
-based upon Mesa.

-<H1>Debugging Tips</H1>
-
-<p>
- Normally Mesa (and OpenGL) records but does not notify the user of
- errors. It is up to the application to call
- <code>glGetError</code> to check for errors. Mesa supports an
- environment variable, MESA_DEBUG, to help with debugging. If
- MESA_DEBUG is defined, a message will be printed to stdout whenever
- an error occurs.
-</p>
-
-<p>
- More extensive error checking is done when Mesa is compiled with the
- DEBUG symbol defined. You'll have to edit the Make-config file and
- add -DDEBUG to the CFLAGS line for your system configuration. You may
- also want to replace any optimization flags with the -g flag so you can
- use your debugger. After you've edited Make-config type 'make clean'
- before recompiling.
-</p>
-<p>
- In your debugger you can set a breakpoint in _mesa_error() to trap Mesa
- errors.
-</p>
-<p>
- There is a display list printing/debugging facility. See the end of
- src/dlist.c for details.

-
-<H2>Adding Extentions</H2>
-
-<p>
-To add a new GL extension to Mesa you have to do at least the following.
-
-<ul>
-<li>
- If glext.h doesn't define the extension, edit include/GL/gl.h and add
- code like this:
- <pre>
- #ifndef GL_EXT_the_extension_name
- #define GL_EXT_the_extension_name 1
- /* declare the new enum tokens */
- /* prototype the new functions */
- /* TYPEDEFS for the new functions */
- #endif
- </pre>
-</li>
-<li>
- In the src/mesa/glapi/ directory, add the new extension functions and
- enums to the gl_API.xml file.
- Then, a bunch of source files must be regenerated by executing the
- corresponding Python scripts.
-</li>
-<li>
- Add a new entry to the <code>gl_extensions</code> struct in mtypes.h
-</li>
-<li>
- Update the <code>extensions.c</code> file.
-</li>
-<li>
- From this point, the best way to proceed is to find another extension,
- similar to the new one, that's already implemented in Mesa and use it
- as an example.
-</li>
-<li>
- If the new extension adds new GL state, the functions in get.c, enable.c
- and attrib.c will most likely require new code.
-</li>
-</ul>
-
-
-
-<H2>Coding Style</H2>
-
-<p>
-Mesa's code style has changed over the years. Here's the latest.
-</p>
-
-<p>
-Comment your code! It's extremely important that open-source code be
-well documented. Also, strive to write clean, easily understandable code.
-</p>
-
-<p>
-3-space indentation
-</p>
-
-<p>
-If you use tabs, set them to 8 columns
-</p>
-
-<p>
-Brace example:
-</p>
-<pre>
- if (condition) {
- foo;
- }
- else {
- bar;
- }
-</pre>
-
-<p>
-Here's the GNU indent command which will best approximate my preferred style:
-</p>
-<pre>
- indent -br -i3 -npcs --no-tabs infile.c -o outfile.c
-</pre>
-
-
-<p>
-Local variable name example: localVarName (no underscores)
-</p>
-
-<p>
-Constants and macros are ALL_UPPERCASE, with _ between words
-</p>
-
-<p>
-Global variables are not allowed.
-</p>
-
-<p>
-Function name examples:
-</p>
-<pre>
- glFooBar() - a public GL entry point (in glapi_dispatch.c)
- _mesa_FooBar() - the internal immediate mode function
- save_FooBar() - retained mode (display list) function in dlist.c
- foo_bar() - a static (private) function
- _mesa_foo_bar() - an internal non-static Mesa function
-</pre>

-<H2>Making a New Mesa Release</H2>
-
-<p>
-These are the instructions for making a new Mesa release.
-</p>
-
-<H3>Get latest source files</H3>
-<p>
-Use git to get the latest Mesa files from the git repository, from whatever
-branch is relevant.
-</p>
-
-
-<H3>Verify and update version info</H3>
-<p>
-Create/edit the docs/relnotes-x.y.html file to document what's new in the release.
-Add the new relnotes-x.y.html file to <a href="relnotes.html">relnotes.html</a>.
-</p>
-
-<p>
-Update the MESA_MAJOR, MESA_MINOR and MESA_TINY version numbers in
-configs/default.
-Also update the VERSION line in the top-level Makefile.
-</p>
-
-<p>
-Make sure the values in src/mesa/main/version.h are correct.
-</p>
-
-<p>
-Update docs/news.html.
-</p>
-
-<p>
-Check in all updates to git.
-</p>
-
-<p>
-Tag the files with the release name (in the form <b>mesa_X_Y</b>)
-with: <code>git tag -a mesa_X_Y</code>
-Then: <code>git push origin mesa_X_Y</code>
-</p>
-
-
-<H3>Make the tarballs</H3>
-<p>
-Make a symbolic link from $(DIRECTORY) to 'Mesa'. For example,
-<code>ln -s Mesa Mesa-7.5</code>
-This is needed in order to make a correct tar file in the next step.
-</p>
-
-<p>
-Make the distribution files. From inside the Mesa directory:
-<pre>
- make tarballs
-</pre>
-
-<p>
-After the tarballs are created, the md5 checksums for the files will
-be computed.
-Add them to the docs/relnotes-X.Y.html file.
-</p>
-
-<p>
-Copy the distribution files to a temporary directory, unpack them,
-compile everything, and run some demos to be sure everything works.
-</p>
-
-<H3>Update the website and announce the release</H3>
-<p>
-Follow the directions on SourceForge for creating a new "release" and
-uploading the tarballs.
-</p>
-
-<p>
-Basically, to upload the tarball files with:
-<br>
-<code>
-rsync -avP ssh Mesa*-X.Y.* USERNAME@frs.sourceforge.net:uploads/
-</code>
-</p>
-
-<p>
-Update the web site by copying the docs/ directory's files to
-/home/users/b/br/brianp/mesa-www/htdocs/ with:
-<br>
-<code>
-sftp USERNAME,mesa3d@web.sourceforge.net
-</code>
-</p>
-
-<p>
-Make an announcement on the mailing lists:
-
-<em>m</em><em>e</em><em>s</em><em>a</em><em>-</em><em>d</em><em>e</em><em>v</em><em>@</em><em>l</em><em>i</em><em>s</em><em>t</em><em>s</em><em>.</em><em>f</em><em>r</em><em>e</em><em>e</em><em>d</em><em>e</em><em>s</em><em>k</em><em>t</em><em>o</em><em>p</em><em>.</em><em>o</em><em>r</em><em>g</em>,

-<BODY>
-<H1>GL Dispatch in Mesa</H1>
-
-<p>Several factors combine to make efficient dispatch of OpenGL functions
-fairly complicated. This document attempts to explain some of the issues
-and introduce the reader to Mesa's implementation. Readers already familiar
-with the issues around GL dispatch can safely skip ahead to the <A
-HREF="#overview">overview of Mesa's implementation</A>.</p>
-
-<H2>1. Complexity of GL Dispatch</H2>
-
-<p>Every GL application has at least one object called a GL <em>context</em>.
-This object, which is an implicit parameter to ever GL function, stores all
-of the GL related state for the application. Every texture, every buffer
-object, every enable, and much, much more is stored in the context. Since
-an application can have more than one context, the context to be used is
-selected by a window-system dependent function such as
-<tt>glXMakeContextCurrent</tt>.</p>
-
-<p>In environments that implement OpenGL with X-Windows using GLX, every GL
-function, including the pointers returned by <tt>glXGetProcAddress</tt>, are
-<em>context independent</em>. This means that no matter what context is
-currently active, the same <tt>glVertex3fv</tt> function is used.</p>
-
-<p>This creates the first bit of dispatch complexity. An application can
-have two GL contexts. One context is a direct rendering context where
-function calls are routed directly to a driver loaded within the
-application's address space. The other context is an indirect rendering
-context where function calls are converted to GLX protocol and sent to a
-server. The same <tt>glVertex3fv</tt> has to do the right thing depending
-on which context is current.</p>
-
-<p>Highly optimized drivers or GLX protocol implementations may want to
-change the behavior of GL functions depending on current state. For
-example, <tt>glFogCoordf</tt> may operate differently depending on whether
-or not fog is enabled.</p>
-
-<p>In multi-threaded environments, it is possible for each thread to have a
-differnt GL context current. This means that poor old <tt>glVertex3fv</tt>
-has to know which GL context is current in the thread where it is being
-called.</p>
-
-<A NAME="overview"/>
-<H2>2. Overview of Mesa's Implementation</H2>
-
-<p>Mesa uses two per-thread pointers. The first pointer stores the address
-of the context current in the thread, and the second pointer stores the
-address of the <em>dispatch table</em> associated with that context. The
-dispatch table stores pointers to functions that actually implement
-specific GL functions. Each time a new context is made current in a thread,
-these pointers a updated.</p>
-
-<p>The implementation of functions such as <tt>glVertex3fv</tt> becomes
-conceptually simple:</p>
-
-<ul>
-<li>Fetch the current dispatch table pointer.</li>
-<li>Fetch the pointer to the real <tt>glVertex3fv</tt> function from the
-table.</li>
-<li>Call the real function.</li>
-</ul>
-
-<p>This can be implemented in just a few lines of C code. The file
-<tt>src/mesa/glapi/glapitemp.h</tt> contains code very similar to this.</p>
-
-<blockquote>
-<table border="1">
-<tr><td><pre>
-void glVertex3f(GLfloat x, GLfloat y, GLfloat z)
-{
- const struct _glapi_table * const dispatch = GET_DISPATCH();
-
- (*dispatch->Vertex3f)(x, y, z);
-}</pre></td></tr>
-<tr><td>Sample dispatch function</td></tr></table>
-</blockquote>
-
-<p>The problem with this simple implementation is the large amount of
-overhead that it adds to every GL function call.</p>
-
-<p>In a multithreaded environment, a niave implementation of
-<tt>GET_DISPATCH</tt> involves a call to <tt>pthread_getspecific</tt> or a
-similar function. Mesa provides a wrapper function called
-<tt>_glapi_get_dispatch</tt> that is used by default.</p>
-
-<H2>3. Optimizations</H2>
-
-<p>A number of optimizations have been made over the years to diminish the
-performance hit imposed by GL dispatch. This section describes these
-optimizations. The benefits of each optimization and the situations where
-each can or cannot be used are listed.</p>
-
-<H3>3.1. Dual dispatch table pointers</H3>
-
-<p>The vast majority of OpenGL applications use the API in a single threaded
-manner. That is, the application has only one thread that makes calls into
-the GL. In these cases, not only do the calls to
-<tt>pthread_getspecific</tt> hurt performance, but they are completely
-unnecessary! It is possible to detect this common case and avoid these
-calls.</p>
-
-<p>Each time a new dispatch table is set, Mesa examines and records the ID
-of the executing thread. If the same thread ID is always seen, Mesa knows
-that the application is, from OpenGL's point of view, single threaded.</p>
-
-<p>As long as an application is single threaded, Mesa stores a pointer to
-the dispatch table in a global variable called <tt>_glapi_Dispatch</tt>.
-The pointer is also stored in a per-thread location via
-<tt>pthread_setspecific</tt>. When Mesa detects that an application has
-become multithreaded, <tt>NULL</tt> is stored in <tt>_glapi_Dispatch</tt>.</p>
-
-<p>Using this simple mechanism the dispatch functions can detect the
-multithreaded case by comparing <tt>_glapi_Dispatch</tt> to <tt>NULL</tt>.
-The resulting implementation of <tt>GET_DISPATCH</tt> is slightly more
-complex, but it avoids the expensive <tt>pthread_getspecific</tt> call in
-the common case.</p>
-
-<blockquote>
-<table border="1">
-<tr><td><pre>
-#define GET_DISPATCH() \
- (_glapi_Dispatch != NULL) \
- ? _glapi_Dispatch : pthread_getspecific(&_glapi_Dispatch_key)
-</pre></td></tr>
-<tr><td>Improved <tt>GET_DISPATCH</tt> Implementation</td></tr></table>
-</blockquote>
-
-<H3>3.2. ELF TLS</H3>
-
-<p>Starting with the 2.4.20 Linux kernel, each thread is allocated an area
-of per-thread, global storage. Variables can be put in this area using some
-extensions to GCC. By storing the dispatch table pointer in this area, the
-expensive call to <tt>pthread_getspecific</tt> and the test of
-<tt>_glapi_Dispatch</tt> can be avoided.</p>
-
-<p>The dispatch table pointer is stored in a new variable called
-<tt>_glapi_tls_Dispatch</tt>. A new variable name is used so that a single
-libGL can implement both interfaces. This allows the libGL to operate with
-direct rendering drivers that use either interface. Once the pointer is
-properly declared, <tt>GET_DISPACH</tt> becomes a simple variable
-reference.</p>
-
-<blockquote>
-<table border="1">
-<tr><td><pre>
-extern __thread struct _glapi_table *_glapi_tls_Dispatch
- __attribute__((tls_model("initial-exec")));
-
-#define GET_DISPATCH() _glapi_tls_Dispatch
-</pre></td></tr>
-<tr><td>TLS <tt>GET_DISPATCH</tt> Implementation</td></tr></table>
-</blockquote>

-<p>Use of this path is controlled by the preprocessor define
-<tt>GLX_USE_TLS</tt>. Any platform capable of using TLS should use this as
-the default dispatch method.</p>
-
-<H3>3.3. Assembly Language Dispatch Stubs</H3>
-
-<p>Many platforms has difficulty properly optimizing the tail-call in the
-dispatch stubs. Platforms like x86 that pass parameters on the stack seem
-to have even more difficulty optimizing these routines. All of the dispatch
-routines are very short, and it is trivial to create optimal assembly
-language versions. The amount of optimization provided by using assembly
-stubs varies from platform to platform and application to application.
-However, by using the assembly stubs, many platforms can use an additional
-space optimization (see <A HREF="#fixedsize">below</A>).</p>
-
-<p>The biggest hurdle to creating assembly stubs is handling the various
-ways that the dispatch table pointer can be accessed. There are four
-different methods that can be used:</p>
-
-<ol>
-<li>Using <tt>_glapi_Dispatch</tt> directly in builds for non-multithreaded
-environments.</li>
-<li>Using <tt>_glapi_Dispatch</tt> and <tt>_glapi_get_dispatch</tt> in
-multithreaded environments.</li>
-<li>Using <tt>_glapi_Dispatch</tt> and <tt>pthread_getspecific</tt> in
-multithreaded environments.</li>
-<li>Using <tt>_glapi_tls_Dispatch</tt> directly in TLS enabled
-multithreaded environments.</li>
-</ol>
-
-<p>People wishing to implement assembly stubs for new platforms should focus
-on #4 if the new platform supports TLS. Otherwise, implement #2 followed by
-#3. Environments that do not support multithreading are uncommon and not
-terribly relevant.</p>
-
-<p>Selection of the dispatch table pointer access method is controlled by a
-few preprocessor defines.</p>
-
-<ul>
-<li>If <tt>GLX_USE_TLS</tt> is defined, method #4 is used.</li>
-<li>If <tt>PTHREADS</tt> is defined, method #3 is used.</li>
-<li>If any of <tt>PTHREADS</tt>,
-<tt>WIN32_THREADS</tt>, or <tt>BEOS_THREADS</tt>
-is defined, method #2 is used.</li>
-<li>If none of the preceeding are defined, method #1 is used.</li>
-</ul>
-
-<p>Two different techniques are used to handle the various different cases.
-On x86 and SPARC, a macro called <tt>GL_STUB</tt> is used. In the preamble
-of the assembly source file different implementations of the macro are
-selected based on the defined preprocessor variables. The assmebly code
-then consists of a series of invocations of the macros such as:
-
-<blockquote>
-<table border="1">
-<tr><td><pre>
-GL_STUB(Color3fv, _gloffset_Color3fv)
-</pre></td></tr>
-<tr><td>SPARC Assembly Implementation of <tt>glColor3fv</tt></td></tr></table>
-</blockquote>
-
-<p>The benefit of this technique is that changes to the calling pattern
-(i.e., addition of a new dispatch table pointer access method) require fewer
-changed lines in the assembly code.</p>
-
-<p>However, this technique can only be used on platforms where the function
-implementation does not change based on the parameters passed to the
-function. For example, since x86 passes all parameters on the stack, no
-additional code is needed to save and restore function parameters around a
-call to <tt>pthread_getspecific</tt>. Since x86-64 passes parameters in
-registers, varying amounts of code needs to be inserted around the call to
-<tt>pthread_getspecific</tt> to save and restore the GL function's
-parameters.</p>
-
-<p>The other technique, used by platforms like x86-64 that cannot use the
-first technique, is to insert <tt>#ifdef</tt> within the assembly
-implementation of each function. This makes the assembly file considerably
-larger (e.g., 29,332 lines for <tt>glapi_x86-64.S</tt> versus 1,155 lines for
-<tt>glapi_x86.S</tt>) and causes simple changes to the function
-implementation to generate many lines of diffs. Since the assmebly files
-are typically generated by scripts (see <A HREF="#autogen">below</A>), this
-isn't a significant problem.</p>
-
-<p>Once a new assembly file is created, it must be inserted in the build
-system. There are two steps to this. The file must first be added to
-<tt>src/mesa/sources</tt>. That gets the file built and linked. The second
-step is to add the correct <tt>#ifdef</tt> magic to
-<tt>src/mesa/glapi/glapi_dispatch.c</tt> to prevent the C version of the
-dispatch functions from being built.</p>
-
-<A NAME="fixedsize"/>
-<H3>3.4. Fixed-Length Dispatch Stubs</H3>
-
-<p>To implement <tt>glXGetProcAddress</tt>, Mesa stores a table that
-associates function names with pointers to those functions. This table is
-stored in <tt>src/mesa/glapi/glprocs.h</tt>. For different reasons on
-different platforms, storing all of those pointers is inefficient. On most
-platforms, including all known platforms that support TLS, we can avoid this
-added overhead.</p>
-
-<p>If the assembly stubs are all the same size, the pointer need not be
-stored for every function. The location of the function can instead be
-calculated by multiplying the size of the dispatch stub by the offset of the
-function in the table. This value is then added to the address of the first
-dispatch stub.</p>
-
-<p>This path is activated by adding the correct <tt>#ifdef</tt> magic to
-<tt>src/mesa/glapi/glapi.c</tt> just before <tt>glprocs.h</tt> is
-included.</p>

-<h1>Mesa EGL</h1>
-
-<p>The current version of EGL in Mesa implements EGL 1.4. More information
-about EGL can be found at
-<a href="http://www.khronos.org/egl/" target="_parent">
-http://www.khronos.org/egl/</a>.</p>
-
-<p>The Mesa's implementation of EGL uses a driver architecture. The main
-library (<code>libEGL</code>) is window system neutral. It provides the EGL
-API entry points and helper functions for use by the drivers. Drivers are
-dynamically loaded by the main library and most of the EGL API calls are
-directly dispatched to the drivers.</p>
-
-<p>The driver in use decides the window system to support.</p>
-
-<h2>Build EGL</h2>
-
-<ol>
-<li>
-<p>Run <code>configure</code> with the desired client APIs and enable
-the driver for your hardware. For example</p>
-
-<pre>
- $ ./configure --enable-gles2 --enable-openvg --enable-gallium-nouveau
-</pre>
-
-<p>The main library and OpenGL is enabled by default. The first option above
-enables <a href="opengles.html">OpenGL ES 2.x</a>. The second option enables
-<a href="openvg.html">OpenVG</a>.</p>
-
-</li>
-
-<li>Build and install Mesa as usual.</li>
-</ol>
-
-<p>In the given example, it will build and install <code>libEGL</code>,
-<code>libGL</code>, <code>libGLESv1_CM</code>, <code>libGLESv2</code>,
-<code>libOpenVG</code>, and one or more EGL drivers.</p>
-
-<h3>Configure Options</h3>
-
-<p>There are several options that control the build of EGL at configuration
-time</p>
-
-<ul>
-<li><code>--enable-egl</code>
-
-<p>By default, EGL is enabled. When disabled, the main library and the drivers
-will not be built.</p>
-
-</li>
-
-<li><code>--with-egl-driver-dir</code>
-
-<p>The directory EGL drivers should be installed to. If not specified, EGL
-drivers will be installed to <code>${libdir}/egl</code>.</p>
-
-</li>
-
-<li><code>--with-egl-platforms</code>
-
-<p>List the platforms (window systems) to support. Its argument is a comma
-seprated string such as <code>--with-egl-platforms=x11,drm</code>. It decides
-the platforms a driver may support. The first listed platform is also used by
-the main library to decide the native platform: the platform the EGL native
-types such as <code>EGLNativeDisplayType</code> or
-<code>EGLNativeWindowType</code> defined for.</p>
-
-<p>The available platforms are <code>x11</code>, <code>drm</code>,
-<code>fbdev</code>, and <code>gdi</code>. The <code>gdi</code> platform can
-only be built with SCons. Unless for special needs, the build system should
-select the right platforms automatically.</p>
-
-</li>
-
-<li><code>--enable-gles1</code> and <code>--enable-gles2</code>
-
-<p>These options enable OpenGL ES support in OpenGL. The result is one big
-internal library that supports multiple APIs.</p>
-
-</li>
-
-<li><code>--enable-gles-overlay</code>
-
-<p>This option enables OpenGL ES as separate internal libraries. This is an
-alternative approach to enable OpenGL ES.</p>
-
-<p>This is only supported by <code>egl_gallium</code>. For systems using DRI
-drivers, <code>--enable-gles1</code> and <code>--enable-gles2</code> are
-suggested instead as all drivers will benefit.</p>
-
-</li>
-
-<li><code>--enable-openvg</code>
-
-<p>OpenVG must be explicitly enabled by this option.</p>
-
-</li>
-
-<li><code>--enable-gallium-egl</code>
-
-<p>Explicitly enable or disable <code>egl_gallium</code>.</p>
-
-</li>
-
-</ul>
-
-<h2>Use EGL</h2>
-
-<h3>Demos</h3>
-
-<p>There are demos for the client APIs supported by EGL. They can be found in
-mesa/demos repository.</p>
-
-<h3>Environment Variables</h3>
-
-<p>There are several environment variables that control the behavior of EGL at
-runtime</p>
-
-<ul>
-<li><code>EGL_DRIVERS_PATH</code>
-
-<p>By default, the main library will look for drivers in the directory where
-the drivers are installed to. This variable specifies a list of
-colon-separated directories where the main library will look for drivers, in
-addition to the default directory. This variable is ignored for setuid/setgid
-binaries.</p>
-
-<p>This variable is usually set to test an uninstalled build. For example, one
-may set</p>
-
-<pre>
- $ export LD_LIBRARY_PATH=$mesa/lib
- $ export EGL_DRIVERS_PATH=$mesa/lib/egl
-</pre>
-
-<p>to test a build without installation</p>
-
-</li>
-
-<li><code>EGL_DRIVER</code>
-
-<p>This variable specifies a full path to an EGL driver and it forces the
-specified EGL driver to be loaded. It comes in handy when one wants to test a
-specific driver. This variable is ignored for setuid/setgid binaries.</p>
-
-</li>
-
-<li><code>EGL_PLATFORM</code>
-
-<p>This variable specifies the native platform. The valid values are the same
-as those for <code>--with-egl-platforms</code>. When the variable is not set,
-the main library uses the first platform listed in
-<code>--with-egl-platforms</code> as the native platform.</p>
-
-<p>Extensions like <code>EGL_MESA_drm_display</code> define new functions to
-create displays for non-native platforms. These extensions are usually used by
-applications that support non-native platforms. Setting this variable is
-probably required only for some of the demos found in mesa/demo repository.</p>
-
-</li>
-
-<li><code>EGL_LOG_LEVEL</code>
-
-<p>This changes the log level of the main library and the drivers. The valid
-values are: <code>debug</code>, <code>info</code>, <code>warning</code>, and
-<code>fatal</code>.</p>
-
-</li>
-
-<li><code>EGL_SOFTWARE</code>
-
-<p>For drivers that support both hardware and software rendering, setting this
-variable to true forces the use of software rendering.</p>
-
-</li>
-</ul>
-
-<h2>EGL Drivers</h2>
-
-<ul>
-<li><code>egl_dri2</code>
-
-<p>This driver supports both <code>x11</code> and <code>drm</code> platforms.
-It functions as a DRI driver loader. For <code>x11</code> support, it talks to
-the X server directly using (XCB-)DRI2 protocol.</p>
-
-<p>This driver can share DRI drivers with <code>libGL</code>.</p>
-
-</li>
-
-<li><code>egl_gallium</code>
-
-<p>This driver is based on Gallium3D. It supports all rendering APIs and
-hardwares supported by Gallium3D. It is the only driver that supports OpenVG.
-The supported platforms are X11, DRM, FBDEV, and GDI.</p>
-
-<p>This driver comes with its own hardware drivers
-(<code>pipe_<hw></code>) and client API modules
-(<code>st_<api></code>).</p>
-
-</li>
-
-<li><code>egl_glx</code>
-
-<p>This driver provides a wrapper to GLX. It uses exclusively GLX to implement
-the EGL API. It supports both direct and indirect rendering when the GLX does.
-It is accelerated when the GLX is. As such, it cannot provide functions that
-is not available in GLX or GLX extensions.</p>
-</li>
-</ul>
-
-<h2>Packaging</h2>
-
-<p>The ABI between the main library and its drivers are not stable. Nor is
-there a plan to stabilize it at the moment. Of the EGL drivers,
-<code>egl_gallium</code> has its own hardware drivers and client API modules.
-They are considered internal to <code>egl_gallium</code> and there is also no
-stable ABI between them. These should be kept in mind when packaging for
-distribution.</p>
-
-<p>Generally, <code>egl_dri2</code> is preferred over <code>egl_gallium</code>
-when the system already has DRI drivers. As <code>egl_gallium</code> is loaded
-before <code>egl_dri2</code> when both are available, <code>egl_gallium</code>
-may either be disabled with <code>--disable-gallium-egl</code> or packaged
-separately.</p>
-
-<h2>Developers</h2>
-
-<p>The sources of the main library and the classic drivers can be found at
-<code>src/egl/</code>. The sources of the <code>egl</code> state tracker can
-be found at <code>src/gallium/state_trackers/egl/</code>.</p>
-
-<p>The suggested way to learn to write a EGL driver is to see how other drivers
-are written. <code>egl_glx</code> should be a good reference. It works in any
-environment that has GLX support, and it is simpler than most drivers.</p>
-
-<h3>Lifetime of Display Resources</h3>
-
-<p>Contexts and surfaces are examples of display resources. They might live
-longer than the display that creates them.</p>
-
-<p>In EGL, when a display is terminated through <code>eglTerminate</code>, all
-display resources should be destroyed. Similarly, when a thread is released
-throught <code>eglReleaseThread</code>, all current display resources should be
-released. Another way to destory or release resources is through functions
-such as <code>eglDestroySurface</code> or <code>eglMakeCurrent</code>.</p>
-
-<p>When a resource that is current to some thread is destroyed, the resource
-should not be destroyed immediately. EGL requires the resource to live until
-it is no longer current. A driver usually calls
-<code>eglIs<Resource>Bound</code> to check if a resource is bound
-(current) to any thread in the destroy callbacks. If it is still bound, the
-resource is not destroyed.</p>
-
-<p>The main library will mark destroyed current resources as unlinked. In a
-driver's <code>MakeCurrent</code> callback,
-<code>eglIs<Resource>Linked</code> can then be called to check if a newly
-released resource is linked to a display. If it is not, the last reference to
-the resource is removed and the driver should destroy the resource. But it
-should be careful here because <code>MakeCurrent</code> might be called with an
-uninitialized display.</p>
-
-<p>This is the only mechanism provided by the main library to help manage the
-resources. The drivers are responsible to the correct behavior as defined by
-EGL.</p>
-
-<h3><code>EGL_RENDER_BUFFER</code></h3>
-
-<p>In EGL, the color buffer a context should try to render to is decided by the
-binding surface. It should try to render to the front buffer if the binding
-surface has <code>EGL_RENDER_BUFFER</code> set to
-<code>EGL_SINGLE_BUFFER</code>; If the same context is later bound to a
-surface with <code>EGL_RENDER_BUFFER</code> set to
-<code>EGL_BACK_BUFFER</code>, the context should try to render to the back
-buffer. However, the context is allowed to make the final decision as to which
-color buffer it wants to or is able to render to.</p>
-
-<p>For pbuffer surfaces, the render buffer is always
-<code>EGL_BACK_BUFFER</code>. And for pixmap surfaces, the render buffer is
-always <code>EGL_SINGLE_BUFFER</code>. Unlike window surfaces, EGL spec
-requires their <code>EGL_RENDER_BUFFER</code> values to be honored. As a
-result, a driver should never set <code>EGL_PIXMAP_BIT</code> or
-<code>EGL_PBUFFER_BIT</code> bits of a config if the contexts created with the
-config won't be able to honor the <code>EGL_RENDER_BUFFER</code> of pixmap or
-pbuffer surfaces.</p>
-
-<p>It should also be noted that pixmap and pbuffer surfaces are assumed to be
-single-buffered, in that <code>eglSwapBuffers</code> has no effect on them. It
-is desirable that a driver allocates a private color buffer for each pbuffer
-surface created. If the window system the driver supports has native pbuffers,
-or if the native pixmaps have more than one color buffers, the driver should
-carefully attach the native color buffers to the EGL surfaces, re-route them if
-required.</p>
-
-<p>There is no defined behavior as to, for example, how
-<code>glDrawBuffer</code> interacts with <code>EGL_RENDER_BUFFER</code>. Right
-now, it is desired that the draw buffer in a client API be fixed for pixmap and
-pbuffer surfaces. Therefore, the driver is responsible to guarantee that the
-client API renders to the specified render buffer for pixmap and pbuffer
-surfaces.</p>
-
-<h3><code>EGLDisplay</code> Mutex</h3>
-
-The <code>EGLDisplay</code> will be locked before calling any of the dispatch
-functions (well, except for GetProcAddress which does not take an
-<code>EGLDisplay</code>). This guarantees that the same dispatch function will
-not be called with the sample display at the same time. If a driver has access
-to an <code>EGLDisplay</code> without going through the EGL APIs, the driver
-should as well lock the display before using it.
-
-<h3>TODOs</h3>
-
-<ul>
-<li>Pass the conformance tests</li>
-<li>Mixed use of OpenGL, OpenGL ES 1.1, and OpenGL ES 2.0 is supported. But
-which one of <code>libGL.so</code>, <code>libGLESv1_CM.so</code>, and
-<code>libGLESv2.so</code> should an application link to? Bad things may happen
-when, say, an application is linked to <code>libGLESv2.so</code> and
-<code>libcairo</code>, which is linked to <code>libGL.so</code> instead.</li>
-
-</ul>

-<H1>Environment Variables</H1>
-
-<p>
-Mesa supports the following environment variables:
-</p>
-<ul>
-<li>MESA_NO_ASM - if set, disables all assembly language optimizations
-<li>MESA_NO_MMX - if set, disables Intel MMX optimizations
-<li>MESA_NO_3DNOW - if set, disables AMD 3DNow! optimizations
-<li>MESA_NO_SSE - if set, disables Intel SSE optimizations
-<li>MESA_DEBUG - if set, error messages are printed to stderr.
-If the value of MESA_DEBUG is "FP" floating point arithmetic errors will
-generate exceptions.

-</a><h1><a name="part1">1. High-level Questions and Answers</a></h1>
-
-<h2><a name="part1">1.1 What is Mesa?</a></h2>
-<p>
-<a name="part1">Mesa is an open-source implementation of the OpenGL specification.
-OpenGL is a programming library for writing interactive 3D applications.
-See the </a><a href="http://www.opengl.org/">OpenGL website</a> for more
-information.
-</p>
-<p>
-Mesa 6.x supports the OpenGL 1.5 specification.
-</p>
-
-
-<h2>1.2 Does Mesa support/use graphics hardware?</h2>
-<p>
-Yes. Specifically, Mesa serves as the OpenGL core for the open-source DRI
-drivers for XFree86/X.org. See the <a href="http://dri.freedesktop.org/">DRI
-website</a> for more information.
-</p>
-<p>
-There have been other hardware drivers for Mesa over the years (such as
-the 3Dfx Glide/Voodoo driver, an old S3 driver, etc) but the DRI drivers
-are the modern ones.
-</p>
-
-<h2>1.3 What purpose does Mesa serve today?</h2>
-<p>
-Hardware-accelerated OpenGL implementations are available for most popular
-operating systems today.
-Still, Mesa serves at least these purposes:
-</p>
-<ul>
-<li>Mesa is used as the core of the open-source XFree86/X.org DRI
- hardware drivers.
-</li>
-<li>Mesa is quite portable and allows OpenGL to be used on systems
- that have no other OpenGL solution.
-</li>
-<li>Software rendering with Mesa serves as a reference for validating the
- hardware drivers.
-</li>
-<li>A software implementation of OpenGL is useful for experimentation,
- such as testing new rendering techniques.
-</li>
-<li>Mesa can render images with deep color channels: 16-bit integer
- and 32-bit floating point color channels are supported.
- This capability is only now appearing in hardware.
-</li>
-<li>Mesa's internal limits (max lights, clip planes, texture size, etc) can be
- changed for special needs (hardware limits are hard to overcome).
-</li>
-</ul>
-
-
-<h2>1.4 What's the difference between"Stand-Alone" Mesa and the DRI drivers?</h2>
-<p>
-<em>Stand-alone Mesa</em> is the original incarnation of Mesa.
-On systems running the X Window System it does all its rendering through
-the Xlib API:
-<ul>
-<li>The GLX API is supported, but it's really just an emulation of the
- real thing.
-<li>The GLX wire protocol is not supported and there's no OpenGL extension
- loaded by the X server.
-<li>There is no hardware acceleration.
-<li>The OpenGL library, libGL.so, contains everything (the programming API,
- the GLX functions and all the rendering code).
-</ul>
-</p>
-<p>
-Alternately, Mesa acts as the core for a number of OpenGL hardware drivers
-within the DRI (Direct Rendering Infrastructure):
-<ul>
-<li>The libGL.so library provides the GL and GLX API functions, a GLX
- protocol encoder, and a device driver loader.
-<li>The device driver modules (such as r200_dri.so) contain a built-in
- copy of the core Mesa code.
-<li>The X server loads the GLX module.
- The GLX module decodes incoming GLX protocol and dispatches the commands
- to a rendering module.
- For the DRI, this module is basically a software Mesa renderer.
-</ul>
-
-
-
-<h2>1.5 How do I upgrade my DRI installation to use a new Mesa release?</h2>
-<p>
-This wasn't easy in the past.
-Now, the DRI drivers are included in the Mesa tree and can be compiled
-separately from the X server.
-Just follow the Mesa <a href="install.html">compilation instructions</a>.
-</p>
-
-
-<h2>1.6 Are there other open-source implementations of OpenGL?</h2>
-<p>
-Yes, SGI's <a href="http://oss.sgi.com/projects/ogl-sample/index.html"
-target="_parent">
-OpenGL Sample Implemenation (SI)</a> is available.
-The SI was written during the time that OpenGL was originally designed.
-Unfortunately, development of the SI has stagnated.
-Mesa is much more up to date with modern features and extensions.

-</a><h1><a name="part2">2. Compilation and Installation Problems</a></h1>
-
-
-<h2><a name="part2">2.1 What's the easiest way to install Mesa?</a></h2>
-<p>
-<a name="part2">If you're using a Linux-based system, your distro CD most likely already
-has Mesa packages (like RPM or DEB) which you can easily install.
-</a></p>
-
-
-<h2><a name="part2">2.2 I get undefined symbols such as bgnpolygon, v3f, etc...</a></h2>
-<p>
-<a name="part2">You're application is written in IRIS GL, not OpenGL.
-IRIS GL was the predecessor to OpenGL and is a different thing (almost)
-entirely.
-Mesa's not the solution.
-</a></p>
-
-
-<h2><a name="part2">2.3 Where is the GLUT library?</a></h2>
-<p>
-<a name="part2">GLUT (OpenGL Utility Toolkit) is in the separate MesaGLUT-x.y.z.tar.gz file.
-If you don't already have GLUT installed, you should grab the MesaGLUT
-package and compile it with the rest of Mesa.
-</a></p>
-
-
-
-<h2><a name="part2">2.4 What's the proper place for the libraries and headers?</a></h2>
-<p>
-<a name="part2">On Linux-based systems you'll want to follow the
-</a><a href="http://oss.sgi.com/projects/ogl-sample/ABI/index.html"
-target="_parent">Linux ABI</a> standard.
-Basically you'll want the following:
-</p>
-<ul>
-<li>/usr/include/GL/gl.h - the main OpenGL header
-</li><li>/usr/include/GL/glu.h - the OpenGL GLU (utility) header
-</li><li>/usr/include/GL/glx.h - the OpenGL GLX header
-</li><li>/usr/include/GL/glext.h - the OpenGL extensions header
-</li><li>/usr/include/GL/glxext.h - the OpenGL GLX extensions header
-</li><li>/usr/include/GL/osmesa.h - the Mesa off-screen rendering header
-</li><li>/usr/lib/libGL.so - a symlink to libGL.so.1
-</li><li>/usr/lib/libGL.so.1 - a symlink to libGL.so.1.xyz
-</li><li>/usr/lib/libGL.so.xyz - the actual OpenGL/Mesa library. xyz denotes the
-Mesa version number.
-</li><li>/usr/lib/libGLU.so - a symlink to libGLU.so.1
-</li><li>/usr/lib/libGLU.so.1 - a symlink to libGLU.so.1.3.xyz
-</li><li>/usr/lib/libGLU.so.xyz - the OpenGL Utility library. xyz denotes the Mesa
-version number.
-</li></ul>
-<p>
-After installing XFree86/X.org and the DRI drivers, some of these files
-may be symlinks into the /usr/X11R6/ tree.
-</p>
-<p>
-The old-style Makefile system doesn't install the Mesa libraries; it's
-up to you to copy them (and the headers) to the right place.
-</p>
-<p>
-The GLUT header and library should go in the same directories.

-</a><h1><a name="part3">3. Runtime / Rendering Problems</a></h1>
-
-<h2><a name="part3">3.1 Rendering is slow / why isn't my graphics hardware being used?</a></h2>
-<p>
-<a name="part3">Stand-alone Mesa (downloaded as MesaLib-x.y.z.tar.gz) doesn't have any
-support for hardware acceleration (with the exception of the 3DFX Voodoo
-driver).
-</a></p>
-<p>
-<a name="part3">What you really want is a DRI or NVIDIA (or another vendor's OpenGL) driver
-for your particular hardware.
-</a></p>
-<p>
-<a name="part3">You can run the <code>glxinfo</code> program to learn about your OpenGL
-library.
-Look for the GL_VENDOR and GL_RENDERER values.
-That will identify who's OpenGL library you're using and what sort of
-hardware it has detected.
-</a></p>
-<p>
-<a name="part3">If your DRI-based driver isn't working, go to the
-</a><a href="http://dri.sf.net/" target="_parent">DRI website</a> for trouble-shooting information.
-</p>
-
-
-<h2>3.2 I'm seeing errors in depth (Z) buffering. Why?</h2>
-<p>
-Make sure the ratio of the far to near clipping planes isn't too great.
-Look
-<a href="http://www.opengl.org/resources/faq/technical/depthbuffer.htm#0040"
-target="_parent"> here</a> for details.
-</p>
-<p>
-Mesa uses a 16-bit depth buffer by default which is smaller and faster
-to clear than a 32-bit buffer but not as accurate.
-If you need a deeper you can modify the parameters to
-<code> glXChooseVisual</code> in your code.
-</p>
-
-
-<h2>3.3 Why Isn't depth buffering working at all?</h2>
-<p>
-Be sure you're requesting a depth buffered-visual. If you set the MESA_DEBUG
-environment variable it will warn you about trying to enable depth testing
-when you don't have a depth buffer.
-</p>
-<p>Specifically, make sure <code>glutInitDisplayMode</code> is being called
-with <code>GLUT_DEPTH</code> or <code>glXChooseVisual</code> is being
-called with a non-zero value for GLX_DEPTH_SIZE.
-</p>
-<p>This discussion applies to stencil buffers, accumulation buffers and
-alpha channels too.
-</p>
-
-
-<h2>3.4 Why does glGetString() always return NULL?</h2>
-<p>
-Be sure you have an active/current OpenGL rendering context before
-calling glGetString.
-</p>
-
-
-<h2>3.5 GL_POINTS and GL_LINES don't touch the right pixels</h2>
-<p>
-If you're trying to draw a filled region by using GL_POINTS or GL_LINES
-and seeing holes or gaps it's because of a float-to-int rounding problem.
-But this is not a bug.
-See Appendix H of the OpenGL Programming Guide - "OpenGL Correctness Tips".
-Basically, applying a translation of (0.375, 0.375, 0.0) to your coordinates
-will fix the problem.
-</p>
-
-<h2>3.6 How can I change the maximum framebuffer size in Mesa's
-<tt>swrast</tt> backend?</h2>
-<p>
-These can be overridden by using the <tt>--with-max-width</tt> and
-<tt>--with-max-height</tt> options. The two need not be equal.
-</p><p>
-Do note that Mesa uses these values to size some internal buffers,
-so increasing these sizes will cause Mesa to require additional
-memory. Furthermore, increasing these limits beyond <tt>4096</tt>
-may introduce rasterization artifacts; see the leading comments in
-<tt>src/mesa/swrast/s_tritemp.h</tt>.
-</p>

-
-<a name="part4">
-</a><h1><a name="part4">4. Developer Questions</a></h1>
-
-<h2>4.1 How can I contribute?</a></h2>
-<p>
-First, join the <a href="http://www.mesa3d.org/lists.html">Mesa3d-dev
-mailing list</a>.
-That's where Mesa development is discussed.
-</p>
-<p>
-The <a href="http://www.opengl.org/documentation" target="_parent">
-OpenGL Specification</a> is the bible for OpenGL implemention work.
-You should read it.
-</p>
-<p>Most of the Mesa development work involves implementing new OpenGL
-extensions, writing hardware drivers (for the DRI), and code optimization.
-</p>
-
-<h2>4.2 How do I write a new device driver?</h2>
-<p>
-Unfortunately, writing a device driver isn't easy.
-It requires detailed understanding of OpenGL, the Mesa code, and your
-target hardware/operating system.
-3D graphics are not simple.
-</p>
-<p>
-The best way to get started is to use an existing driver as your starting
-point.
-For a software driver, the X11 and OSMesa drivers are good examples.
-For a hardware driver, the Radeon and R200 DRI drivers are good examples.
-</p>
-<p>The DRI website has more information about writing hardware drivers.
-The process isn't well document because the Mesa driver interface changes
-over time, and we seldome have spare time for writing documentation.
-That being said, many people have managed to figure out the process.
-</p>
-<p>
-Joining the appropriate mailing lists and asking questions (and searching
-the archives) is a good way to get information.
-</p>
-
-
-<h2>4.3 Why isn't GL_EXT_texture_compression_s3tc implemented in Mesa?</h2>
-<p>
-The <a href="http://oss.sgi.com/projects/ogl-sample/registry/EXT/texture_compression_s3tc.txt" target="_parent">specification for the extension</a>
-indicates that there are intellectual property (IP) and/or patent issues
-to be dealt with.
-</p>
-<p>We've been unsucessful in getting a response from S3 (or whoever owns
-the IP nowadays) to indicate whether or not an open source project can
-implement the extension (specifically the compression/decompression
-algorithms).
-</p>
-<p>
-In the mean time, a 3rd party <a href=
-"http://homepage.hispeed.ch/rscheidegger/dri_experimental/s3tc_index.html"
-target="_parent">plug-in library</a> is available.

-<center><h1>Mesa fbdev/DRI Drivers</h1></center>
-<br>
-
-<h1><center>NOTE: this information is obsolete and will be removed at
-a future date</center></h1>
-
-<h1>1. Introduction</h1>
-
-<p>
-The fbdev/DRI environment supports hardware-accelerated 3D rendering without
-the X window system. This is typically used for embedded applications.
-</p>
-
-<p>
-Contributors to this project include Jon Smirl, Keith Whitwell and Dave Airlie.
-</p>
-
-<p>
-Applications in the fbdev/DRI environment use
-the MiniGLX interface to choose pixel
-formats, create rendering contexts, etc. It's a subset of the GLX and
-Xlib interfaces allowing some degree of application portability between
-the X and X-less environments.
-</p>
-
-<p>
-Note that this environment is not well-supported and these instructions
-may not be completely up to date.
-</p>
-<br>
-
-
-
-<h1>2. Compilation</h1>
-<p>
-
-<h2>2.1 glxproto</h2>
-
-Get <a href="http://cvsweb.xfree86.org/cvsweb/*checkout*/xc/include/GL/glxproto.h?rev=1.9">glxproto.h</a>. Copy it to the /mesa/include/GL/ directory.
-</p>
-
-<h2>2.2 libpciaccess</h2>
-<p>
-Check if you have libpciaccess installed:
-</p>
-
-<pre>pkg-config --modversion pciaccess
-</pre>
-<p>
-If not you can download the latest code from:
-</p>
-<pre> git clone git://anongit.freedesktop.org/git/xorg/lib/libpciaccess
-</pre>
-<p>
-Run autogen.sh to generate a configure file. autogen.sh uses autoconf
-utility. This utility may not be installed with your linux distro,
-check if it is available. if not you can use your package manager or
-type:
-</p>
-<pre>sudo apt-get install autoconf
-</pre>
-The next step is to install the libpciaccess library.
-<pre>make
-make install
-</pre>
-<p> Now your libpciaccess.a file is saved into /usr/local/lib
-directory. If you have a libpciaccess.a in /usr/lib you may simply copy
-and overwrite these files. Don't forget to copy libpciaccess.pc file to
-/usr/lib/pkgconfig, which is also located in /usr/local/lib/pkgconfig/.
-Or you may use the following system variables:
-</p>
-<pre>export LD_LIBRARY_PATH=/usr/local/lib
-export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
-</pre>
-
-<h2>2.3 drm</h2>
-
-<p>The next step is to compile the drm. DRM consists of two seperate parts,
-the DRM client library(lindrm.so) and kernel device module(such as
-radeon.ko). We need to make a small change in kernel device module. So
-you need to download the kernel source. You may choose the nearest
-mirror from www.kernel.org, or you are using Fedora Core 5, for
-example, you may need to install RPMs such as:
-kernel-smp-devel-2.16.15-1.2054_FC5.i686.rpm
-kernel-devel-2.6.15-1.2054_FC5.i686.rpm
-etc. You can find a detailed information <a href="http://www.howtoforge.com/kernel_compilation_fedora">here.</a>
-</p>
-
-<p>You will find drm_drv.c at /usr/src/LINUX-VERSION/drivers/char/drm/. Edit this code and comment out the following part:
-</p>
-
-<pre>
- /* ||
- ((ioctl->flags & DRM_MASTER) && !priv->master)*/
-</pre>
-Now you are ready to compile your kernel. If your kernel version is
-identical to the version you have compiled, you can simply over write
-your new "ko" files over older ones. If you have compiled a different
-kernel, you must configure your grub or lilo to be able to boot your
-new kernel. <p>
-You'll need fbdev header files. Check with:
-</p>
-<pre>
- ls -l /usr/include/linux/fb.
-</pre>
-<p>This file may be missing if you have not installed linux header files.
-
-
-<h2>2.4 Mesa</h2>
-
-</p><p>Get latest development Mesa sources from git repository
-(currently 7.1-prerelease)
-</p>
-<pre>
- git clone git://anongit.freedesktop.org/git/mesa/mesa
-</pre>
-
-<p>You will need the makedepend utility which is a part of mesa project
-to build your linux-solo. You probably wont have this utility. You can
-download its source from following git repulsitory:
-</p>
-<pre>
- git clone git://anongit.freedesktop.org/git/xorg/util/makedepend
-</pre>
-
-<p>Get the latest stable mesa version from SourceForge (currently 7.0.3)
-<a href="http://sourceforge.net/project/showfiles.php?group_id=3">http://sourceforge.net/project/showfiles.php?group_id=3</a>
-</p>
-
-<p>Copy the miniglx folder from 7.1-prerelease to 7.0.3.
-You may also extract GLUT to 7.0.3 version at this step.
-</p>
-
-<p>Edit linux-solo.conf at /conf directory, just only compile the
-graphics driver you need, delete the unwanted drivers names from the
-list(some drivers are causing problems...)
-</p>
-<pre>
- while(build==0)
- {
- make linux-solo
-
- There will be some missing header files, copy them from 7.1-prerelease
- }
-</pre>
-
-<p>
-When complete you should have the following:
-</p>
-<ul>
-<li>lib/libGL.so - the GL library which applications link with
-</li><li>lib/*_dri_so - DRI drivers
-</li><li>lib/miniglx.conf - sample MiniGLX config file
-</li><li>progs/miniglx/* - several MiniGLX sample programs
-</li></ul>
-
-To install these files into appropriate locations in system:
-<pre>
- make install
-</pre>
-
-Now your openGL libraries are copied to /usr/local/lib and
-miniglx.conf is copied to /etc. You may copy them to /usr/lib and
-overwrite your old GL libraries. Or you may export following variable:
-
-<pre>
- export LIBGL_DRIVERS_PATH=/usr/local/lib
-</pre>
-<br>
-
-
-<h1>3. Using fbdev/DRI</h1>
-
-<p>
-If an X server currently running, exit/stop it so you're working from
-the console. Following command shuts down the x window and also the multi user support.
-</p>
-<pre>
- init 1
-</pre>
-
-<p>Also you may define the runlevel as 1 in "/etc/inittab". Your system
-will always start in single user mode and without x-window with this
-option set.
-</p><h2>3.1 Load Kernel Modules</h2>
-
-<p>
-You'll need to load the kernel modules specific to your graphics hardware.
-Typically, this consists of the agpgart module, an fbdev driver module
-and the DRM kernel module.
-</p>
-<p>
-As root, the kernel modules can be loaded as follows:
-</p>
-
-<p>
-If you have Intel i915/i945 hardware:
-</p>
-<pre> modprobe agpgart # the AGP GART module
- modprobe intelfb # the Intel fbdev driver
- modprobe i915 # the i915/945 DRI kernel module
-</pre>
-
-<p>
-If you have ATI Radeon/R200 hardware:
-</p>
-<pre> modprobe agpgart # the AGP GART module
- modprobe radeonfb # the Radeon fbdev driver
- modprobe radeon # the Radeon DRI kernel module
-</pre>
-
-<p>
-If you have ATI Rage 128 hardware:
-</p>
-<pre> modprobe agpgart # the AGP GART module
- modprobe aty128fb # the Rage 128 fbdev driver
- modprobe r128 # the Rage 128 DRI kernel module
-</pre>
-
-<p>
-If you have Matrox G200/G400 hardware:
-</p>
-<pre> modprobe agpgart # the AGP GART module
- modprobe mgafb # the Matrox fbdev driver
- modprobe mga # the Matrox DRI kernel module
-</pre>
-
-<p>
-To verify that the agpgart, fbdev and drm modules are loaded:
-</p>
-<pre> ls -l /dev/agpgart /dev/fb* /dev/dri
-</pre>
-<p>
-Alternately, use lsmod to inspect the currently installed modules.
-If you have problems, look at the output of dmesg.
-</p>
-
-
-<h2>3.2 Configuration File</h2>
-
-<p>
-review/edit /etc/miniglx.conf.
-Alternately, the MINIGLX_CONF environment variable can be used to
-indicate the location of miniglx.conf
-</p>
-
-To determine the pciBusID value, run lspci and examine the output.
-For example:
-<p></p>
-<pre> /sbin/lspci:
- 00:02.0 VGA compatible controller: Intel Corporation 82915G/GV/910GL Express Chipset Family Graphics Controller (rev 04)
-</pre>
-<p>
-00:02.0 indicates that pciBusID should be PCI:0:2:0
-</p>
-
-
-
-
-<h2>3.3 Running fbdev/DRI Programs</h2>
-
-<p>
-Make sure your LD_LIBRARY_PATH environment variable is set to the
-location of the libGL.so library. You may need to append other paths
-to LD_LIBRARY_PATH if libpciaccess.so is in a non-standard location,
-for example.
-</p>
-
-<p>
-Change to the <code>Mesa/progs/miniglx/</code> directory and
-start the sample_server program in the background:
-</p>
-<pre> ./sample_server &
-</pre>
-
-<p>
-Then try running the <code>miniglxtest</code> program:
-</p>
-<pre> ./miniglxtest
-</pre>
-<p>
-You should see a rotating quadrilateral which changes color as it rotates.
-It will exit automatically after a bit.
-</p>
-
-<p>
-If you run other tests in the miniglx/ directory, you may want to run
-them from a remote shell so that you can stop them with ctrl-C.
-</p>
-<br>
-
-
-<h1>4.0 Troubleshooting</h1>
-
-<ol>
-<li>
-If you try to run miniglxtest and get the following:
-<br>
-<pre> [miniglx] failed to probe chipset
- connect: Connection refused
- server connection lost
-</pre>
-It means that the sample_server process is not running.
-<br>
-<br>
-</li>
-</ol>
-
-
-<h1>5.0 Programming Information</h1>
-
-<p>
-OpenGL/Mesa is interfaced to fbdev via the MiniGLX interface.
-MiniGLX is a subset of Xlib and GLX API functions which provides just
-enough functionality to setup OpenGL rendering and respond to simple
-input events.
-</p>
-
-<p>
-Since MiniGLX is a subset of the usual Xlib and GLX APIs, programs written
-to the MiniGLX API can also be run on full Xlib/GLX implementations.
-This allows some degree of flexibility for software development and testing.
-</p>
-
-<p>
-However, the MiniGLX API is not binary-compatible with full Xlib/GLX.
-Some of the structures are different and some macros/functions work
-differently.
-See the GL/miniglx.h header file for details.

-<center><H1>Mesa glFBDev Driver</H1></center>
-
-
-<H1>1. Introduction</H1>
-
-<p>
-The GLFBDev driver interface allows one to do OpenGL rendering into a
-framebuffer managed with the Linux's fbdev interface.
-</p>
-
-<p>
-Basically, the programmer uses the fbdev functions to initialize the
-graphics hardware and setup the framebuffer.
-Then, using a calls to Mesa's glFBDev API functions, one can render
-into the framebuffer with the OpenGL API functions.
-</p>
-
-<p>
-Note, only software rendering is supported; there is no hardware
-acceleration.
-</p>
-
-
-<p>
-The GL/glfbdev.h header file defines the glFBDev interface.
-</p>
-
-<p>
-The progs/fbdev/glfbdevtest.c demonstrates how to use the glFBDev interface.
-</p>
-
-
-<p>
-For more information about fbdev, see the
-<a href="http://www.tldp.org/HOWTO/Framebuffer-HOWTO.html" target="_parent">
-Framebuffer Howto</a>
-</p>
-<p>
-You will need at minimum, a framebuffer device, check /dev/fb0
-</p>
-
-<h1>2. Compilation</h1>
-
-<p>
-To compile Mesa with support for the glFBDev interface:
-<pre>
- make realclean
- make linux-fbdev
-</pre>
-
-<p>
-When compilation is finished look in progs/glfbdev/ for the glfbdevtest demo.
-</p>
-<h1>3. Permissions</h1>
-
-<p>
-Typically /dev/fb/0 is grouped to the video group. It may be useful to add
-your user to the video group so the demos will not have to be run as root.
-To use fbdevglut with the prefered tty input, you should add the user to the
-tty group as well
-<p>
-
-<h1>4. Using fbdevglut</h1>
-Almost all of the programs in the progs directory use glut, and they compile with fbdevglut.
-
-<p>
-To compile the redbook sample programs:
-<pre>
- cd progs/redbook
- make
-</pre>
-</p>
-<p>glut features not supported:
-<li>Overlays
-<li>Subwindows
-<li>Input devices other than Keyboard/Mouse
-<li>No support for GLUT_MULTISAMPLE, GLUT_STEREO, or GLUT_LUMINANCE
-<li>Cursor and Menu Support will flicker in GLUT_SINGLE mode
-
-<p>Keyboard input is read by opening /dev/tty and reading keycodes in medium raw mode.
-<p>Mouse input is read from env var MOUSE, or /dev/gpmdata and should be in ms3 format.
-To forward data in this format to /dev/gpmdata, run gpm with the -Rms3 option.
-<p> glutInit allows glut programs to pass parameters to the glut library, currently the
-following options are supported for fbdevglut:
-<p><li>-geometry widthxheight -- This will force the resolution to be widthxheight instead of autodetecting.
-The modes are read from /etc/fb.modes
-<p><li>-bpp -- This will force the bitdepth to the one specified
-<p><li>-vt -- This allows you to specify the virtual terminal to attach keyboard input to. It is useful to specify when running inside screen.
-<p><li>-mousespeed -- A floating point multiplication factor to increase mouse speed
-<p><li>-nomouse -- Disable mouse support
-<p><li>-nokeyboard -- Disable keyboard support (this will probably break mouse support as well)
-<p><li>-stdin -- Use stdin for input instead of attaching to kbd in medium-raw mode.
-This will make it impossible to detect keypresses like Shift+Tab, you will also need to specify -gpmmouse for mouse support. This option can be used with a debugger, and it is possible to single step a program with gdb and set the FRAMEBUFFER environment variable to a different framebuffer for display. The program will not be able to handle vt switching on it's own, so it will always display.
-<p><li>-gpmmouse -- This will attempt to connect to the /dev/gpmctl socket using liblow
-for mouse data. Gpm does not provide this data when in graphics mode, so vt switching
-will briefly display text. This mode typically has no initial mouse delay.
-<p><li>-- Ignore any additional arguments
-<p>Notes:
-<p>
-1. The mouse pointer flickers in single buffering mode, as it must be rendered in software. Hopefully in the future there will be a way to access hardware cursors in fbdev devices.

-<H1>SGI SI GLU</H1>
-
-(Silicon Graphics, Inc. Sample Implementation of the OpenGL Utility library)
-
-<p>
-SGI open-sourced their OpenGL Sample Implementation (SI) in January, 2000.
-This includes the GLU library.
-</p>
-
-<p>
-The SI GLU library implements GLU version 1.3 whereas the original
-Mesa GLU library only implemented version 1.2.
-We recommend using the SI GLU library instead of Mesa's GLU library
-since it's more up-to-date, complete and reliable.
-We're no longer developing the original Mesa GLU library.
-</p>
-
-<p>
-The SI GLU library code is included in the Mesa distribution.
-You don't have to download it separately.
-</p>
-
-
-<p>
-<b>Olivier Michel</b> has made Linux RPMs of GLU for i386 and PowerPC.
-You can download them from the
-<a href="http://www.sourceforge.net/project/showfiles.php?group_id=3"
-target="_parent">download area</a> under <b>Miscellaneous</b>.
-</p>
-

-<BODY>
-
-<H1>Help Wanted / To-Do List</H1>
-
-<p>
-We can always use more help with the Mesa project.
-Here are some specific ideas and areas where help would be appreciated:
-</p>
-
-<ol>
-<li>
-<b>Driver patching and testing.</b>
-Patches are often posted to the mesa3d-dev mailing list, but aren't
-immediately checked into git because not enough people are testing them.
-Just applying patches, testing and reporting back is helpful.
-<li>
-<b>Driver debugging.</b>
-There are plenty of open bugs in the bug database.
-<li>
-<b>Remove aliasing warnings.</b>
-Enable gcc -Wstrict-aliasing=2 -fstrict-aliasing and track down aliasing
-issues in the code.
-<li>
-<b>Windows driver building, testing and maintenance.</b>
-The Visual Studio project files aren't always updated in a timely manner
-when new source files are added or old ones are removed.
-Fixing these tends to delay new Mesa releases.
-<li>
-<b>Maintenance and testing of lesser-used drivers.</b>
-Drivers such as DOS/DJGPP, GGI, etc that aren't being maintained are being
-deprecated starting in Mesa 7.3.
-<li>
-<b>Contribute more tests to
-<a href="http://glean.sourceforge.net/" target="_parent">glean</a>.</b>
-<li>
-<b>Automatic testing.
-</b>
-It would be great if someone would set up an automated system for grabbing
-the latest Mesa code and run tests (such as glean) then report issues to
-the mailing list.
-</ol>
-
-
-<p>
-If you want to do something new in Mesa, first join the Mesa developer's
-mailing list.
-Then post a message to propose what you want to do, just to make sure
-there's no issues.
-</p>
-
-</p>
-Anyone is welcome to contribute code to the Mesa project.
-By doing so, it's assumed that you agree to the code's licensing terms.
-</p>
-
-<p>
-Finally:
-<p>
-
-<ol>
-<li>Try to write high-quality code that follows the existing style.
-<li>Use uniform indentation, write comments, use meaningful identifiers, etc.
-<li>Test your code thoroughly. Include test programs if appropriate.
-</ol>

-<h3>1.1 Prerequisites for DRI and hardware acceleration</h3>
-
-<p>
-The following are required for DRI-based hardware acceleration with Mesa:
-</p>
-
-<ul>
-<li><a href="http://xorg.freedesktop.org/releases/individual/proto/">dri2proto</a> version 1.99.3 or later
-<li>Linux 2.6.28

-<a name="autoconf">
-<h3>1.2 Building with Autoconf</h3>
-
-<p>
-Mesa may be <a href="autoconf.html">built using autoconf</a>.
-This should work well on most GNU-based systems.
-If that fails the traditional Mesa build system is available.
-
-
-
-<a name="traditional">
-<h3>1.3 Building with traditional Makefiles</h3>
-
-<p>
-The traditional Mesa build system is based on a collection of pre-defined
-system configurations.
-</p>
-<p>
-To see the list of configurations, just type <code>make</code>.
-Then choose a configuration from the list and type <code>make</code>
-<em>configname</em>.
-</p>
-
-<p>
-Mesa may be built in several different ways using the predefined configurations:
-</p>
-<ul>
-<li><b><em>Stand-alone/Xlib mode</em></b> - Mesa will be compiled as
-a software renderer using Xlib to do all rendering.
-The libGL.so library will be a self-contained rendering library that will
-allow you to run OpenGL/GLX applications on any X server (regardless of
-whether it supports the GLX X server extension).
-You will <em>not</em> be able to use hardware 3D acceleration.
-<p>
-To compile stand-alone Mesa type <code>make</code> in the top-level directory.
-You'll see a list of supported system configurations.
-Choose one from the list (such as linux-x86), and type:
-</p>
-<pre>
- make linux-x86
-</pre>
-<p>This will produce libGL.so and several other libraries</p>
-</li>
-
-<li><b><em>DRI/accelerated</em></b> - The DRI hardware drivers for
-accelerated OpenGL rendering (for ATI, Intel, Matrox, etc) will be built.
-The libGL.so library will support the GLX extension and will load/use
-the DRI hardware drivers.
-
-
-<p>
-Build Mesa and the DRI hardware drivers by running
-</p>
-<pre>

-<h3>1.5 Running the demos</h3>
-
-<p>
-If you downloaded/unpacked the MesaDemos-x.y.z.tar.gz archive or
-obtained Mesa from CVS, the <b>progs/</b> directory will contain a
-bunch of demonstration programs.
-</p>
-
-<p>
-Before running a demo, you'll probably have to set two environment variables
-to indicate where the libraries are located. For example:
-<p>
-<blockquote>
-<b>cd lib/</b>
-<br>
-<b>export LD_LIBRARY_PATH=${PWD}</b>
-<br>
-<b>export LIBGL_DRIVERS_PATH=${PWD}</b> (if using DRI drivers)
-</blockquote>
-
-<p>
-Next, change to the Mesa/demos/ directory:
-</p>
-<blockquote>
-<b>cd ../progs/demos</b>
-</blockquote>
-
-<p>
-Run a demo such as gears:
-</p>
-<blockquote>
-<b>./gears</b>
-</blockquote>
-
-<p>
-If this doesn't work, try the <b>Mesa/progs/xdemos/glxinfo</b> program
-and see that it prints the expected Mesa version number.
-</p>
-
-<p>
-If you're using Linux or a similar OS, verify that the demo program is
-being linked with the proper library files:
-</p>
-<blockquote>
-<b>ldd gears</b>
-</blockquote>
-
-<p>
-You should see something like this:

-<H3>1.6 Installing the header and library files</H3>
-
-<p>
-The standard location for the OpenGL header files on Unix-type systems is
-in <code>/usr/include/GL/</code>.
-The standard location for the libraries is <code>/usr/lib/</code>.
-For more information see, the
-<a href="http://oss.sgi.com/projects/ogl-sample/ABI/" target="_parent">
-Linux/OpenGL ABI specification</a>.
-</p>
-
-<p>
-If you'd like Mesa to co-exist with another implementation of OpenGL that's
-already installed, you'll have to choose different directories, like
-<code>/usr/local/include/GL/</code> and <code>/usr/local/lib/</code>.
-</p>
-
-<p>
-To install Mesa's headers and libraries, run <code>make install</code>.
-But first, check the Mesa/configs/default file and examine the values
-of the <b>INSTALL_DIR</b> and <b>DRI_DRIVER_INSTALL_DIR</b> variables.
-Change them if needed, then run <code>make install</code>.
-</p>
-
-<p>
-The variable
-<b>DESTDIR</b> may also be used to install the contents to a temporary
-staging directory.
-This can be useful for package management.
-For example: <code>make install DESTDIR=/somepath/</code>
-</p>
-
-<p>
-Note: at runtime you can use the LD_LIBRARY_PATH environment variable
-(on Linux at least) to switch
-between the Mesa libraries and other vendor's libraries whenever you want.
-This is a handy way to compare multiple OpenGL implementations.

-<p>
-When compiling your OpenGL application you can use pkg-config to determine

-
-<H1>Introduction</H1>
-
-<p>
-Mesa is an open-source implementation of the
-<a href="http://www.opengl.org/" target="_parent">OpenGL</a> specification -
-a system for rendering interactive 3D graphics.
-</p>
-
-<p>
-A variety of device drivers allows Mesa to be used in many different
-environments ranging from software emulation to complete hardware acceleration
-for modern GPUs.
-</p>
-
-<p>
-Mesa ties into several other open-source projects: the
-<a href="http://dri.freedesktop.org/" target="_parent">Direct Rendering
-Infrastructure</a> and <a href="http://x.org" target="_parent">X.org</a> to
-provide OpenGL support to users of X on Linux, FreeBSD and other operating
-systems.
-</p>
-
-
-
-<H1>Project History</H1>
-
-<p>
-The Mesa project was originally started by Brian Paul.
-Here's a short history of the project.
-</p>
-
-<p>
-August, 1993: I begin working on Mesa in my spare time. The project
-has no name at that point. I was simply interested in writing a simple
-3D graphics library that used the then-new OpenGL API. I was partially
-inspired by the <em>VOGL</em> library which emulated a subset of IRIS GL.
-I had been programming with IRIS GL since 1991.
-</p>
-
-<p>
-November 1994: I contact SGI to ask permission to distribute my OpenGL-like
-graphics library on the internet. SGI was generally receptive to the
-idea and after negotiations with SGI's legal department, I get permission
-to release it.
-</p>
-
-<p>
-February 1995: Mesa 1.0 is released on the internet. I expected that
-a few people would be interested in it, but not thousands.
-I was soon receiving patches, new features and thank-you notes on a
-daily basis. That encouraged me to continue working on Mesa. The
-name Mesa just popped into my head one day. SGI had asked me not to use
-the terms <em>"Open"</em> or <em>"GL"</em> in the project name and I didn't
-want to make up a new acronym. Later, I heard of the Mesa programming
-language and the Mesa spreadsheet for NeXTStep.
-</p>
-
-<p>
-In the early days, OpenGL wasn't available on too many systems.
-It even took a while for SGI to support it across their product line.
-Mesa filled a big hole during that time.
-For a lot of people, Mesa was their first introduction to OpenGL.
-I think SGI recognized that Mesa actually helped to promote
-the OpenGL API, so they didn't feel threatened by the project.
-</p>
-
-
-<p>
-1995-1996: I continue working on Mesa both during my spare time and during
-my work hours at the Space Science and Engineering Center at the University
-of Wisconsin in Madison. My supervisor, Bill Hibbard, lets me do this because
-Mesa is now being using for the <a href="http://www.ssec.wisc.edu/%7Ebillh/vis.html" target="_parent">Vis5D</a> project.
-</p><p>
-October 1996: Mesa 2.0 is released. It implements the OpenGL 1.1 specification.
-</p>
-
-<p>
-March 1997: Mesa 2.2 is released. It supports the new 3dfx Voodoo graphics
-card via the Glide library. It's the first really popular hardware OpenGL
-implementation for Linux.
-</p>
-
-<p>
-September 1998: Mesa 3.0 is released. It's the first publicly-available
-implementation of the OpenGL 1.2 API.
-</p>
-
-<p>
-March 1999: I attend my first OpenGL ARB meeting. I contribute to the
-development of several official OpenGL extensions over the years.
-</p>
-
-<p>
-September 1999: I'm hired by Precision Insight, Inc. Mesa is a key
-component of 3D hardware acceleration in the new DRI project for XFree86.
-Drivers for 3dfx, 3dLabs, Intel, Matrox and ATI hardware soon follow.
-</p>
-
-<p>
-October 2001: Mesa 4.0 is released.
-It implements the OpenGL 1.3 specification.
-</p>
-
-
-<p>
-November 2001: I cofounded Tungsten Graphics, Inc. with Keith Whitwell,
-Jens Owen, David Dawes and Frank LaMonica.
-Tungsten Graphics was acquired by VMware in December 2008.
-</p>
-
-<p>
-November 2002: Mesa 5.0 is released.
-It implements the OpenGL 1.4 specification.
-</p>
-
-<p>
-January 2003: Mesa 6.0 is released. It implements the OpenGL 1.5
-specification as well as the GL_ARB_vertex_program and
-GL_ARB_fragment_program extensions.
-</p>
-
-<p>
-June 2007: Mesa 7.0 is released, implementing the OpenGL 2.1 specification
-and OpenGL Shading Language.
-</p>
-
-
-<p>
-Ongoing: Mesa is used as the core of many hardware OpenGL drivers for
-the XFree86 and X.org X servers within the
-<A href="http://dri.freedesktop.org/" target="_parent">DRI project</A>.
-I continue to enhance Mesa with new extensions and features.
-</p>
-
-
-
-<H1>Major Versions</H1>
-
-<p>
-This is a summary of the major versions of Mesa.
-Mesa's major version number has been incremented whenever a new version
-of the OpenGL specification is implemented.

-User's Guide
-------------
-
-Using libGL.so
-
-The libGL.so library defines the gl- and glX-prefixed functions needed to
-run OpenGL programs. OpenGL client applications should link with the
--lGL option to use it.
-
-libGL.so serves two primary functions: GLX protocol generation for indirect
-rendering and loading/management of hardware drivers for direct rendering.
-
-When libGL.so initializes itself it uses the DRI to determine the
-appropriate hardware driver for each screen on the local X display.
-The hardware drivers are expected to be in the /usr/X11R6/lib/modules/dri/
-directory. Drivers are named with the convention <name>_dri.so where
-<name> is a driver such as "tdfx", "i810", "gamma", etc.
-
-The LIBGL_DRIVERS_DIR environment variable may be used to specify a
-different DRI modules directory, overriding /usr/X11R6/lib/modules/dri/.
-This environment variable is ignored in setuid programs for security
-reasons.
-
-When libGL.so is unable to locate appropriate hardware drivers it will
-fall back to using indirect GLX rendering.
-
-To aid in solving problems, libGL.so will print diagnostic messages to
-stderr if the LIBGL_DEBUG environment variable is defined.
-
-libGL.so is thread safe. The overhead of thread safety for common,
-single-thread clients is negligible. However, the overhead of thread
-safety for multi-threaded clients is significant. Each GL API call
-requires two calls to pthread_get_specific() which can noticably
-impact performance. Warning: libGL.so is thread safe but individual
-DRI drivers may not be. Please consult the documentation for a driver
-to learn if it is thread safe.
-
-
-
-Indirect Rendering
-
-You can force indirect rendering mode by setting the LIBGL_ALWAYS_INDIRECT
-environment variable. Hardware acceleration will not be used.
-
-
-
-libGL.so Extensibility
-
-libGL.so is designed to be extended without upgrading. That is,
-drivers may install new OpenGL extension functions into libGL.so
-without requiring libGL.so to be replaced. Clients of libGL.so should
-use the glXGetProcAddressEXT() function to obtain the address of
-functions by name. For more details of GLX_ARB_get_proc_address see
-http://oss.sgi.com/projects/ogl-sample/registry/ARB/get_proc_address.spec
-
-libGL.so is also designed with flexibility such that it may be used
-with many generations of hardware drivers to come.
-

-
-Driver Developer's Guide
-------------------------
-
-This section describes the requirements to make an XFree86 4.0
-libGL.so-compatible hardware driver. It is not intended for end
-users of libGL.so.
-
-
-XFree86 source files
-
-libGL.so is built inside XFree86 with sources found in xc/lib/GL/.
-Specifically, libGL.so is built from:
-
- xc/lib/GL/glx/*.c
- xc/lib/dri/XF86dri.c
- xc/lib/dri/dri_glx.c
- xc/lib/GL/mesa/src/glapi.c
- xc/lib/GL/mesa/src/glapitemp.h
- xc/lib/GL/mesa/src/glapitable.h
- xc/lib/GL/mesa/src/glapioffsets.h
- xc/lib/GL/mesa/src/glapinoop.c
- xc/lib/GL/mesa/src/glheader.h
- xc/lib/GL/mesa/src/glthread.c
- xc/lib/GL/mesa/src/glthread.h
- xc/lib/GL/mesa/src/X86/glapi_x86.S
- xc/lib/GL/mesa/src/X86/assyntax.h
-
-Understand that the mesa/src/gl*.[ch] files are not tied to Mesa. They
-have no dependencies on the rest of Mesa and are designed to be reusable
-in a number of projects.
-
-The glapi_x86.X and assyntax.h files implement x86-optimized dispatch
-of GL functions. They are not required; C-based dispatch can be used
-instead, with a slight performance penalty.
-
-
-
-Driver loading and binding
-
-When libGL.so initializes itself (via the __glXInitialize function) a
-call is made to driCreateDisplay(). This function uses DRI facilities
-to determine the driver file appropriate for each screen on the local
-display. Each screen's driver is then opened with dlopen() and asked
-for its __driCreateScreen() function. The pointers to the __driCreateScreen()
-functions are kept in an array, indexed by screen number, in the
-__DRIdisplayRec struct.
-
-When a driver's __driCreateScreen() function is called, it must initialize
-a __DRIscreenRec struct. This struct acts as the root of a tree of
-function pointers which are called to create and destroy contexts and
-drawables and perform all the operations needed by the GLX interface.
-See the xc/lib/GL/glx/glxclient.h file for details.
-
-
-
-Dynamic Extension Function Registration
-
-In order to provide forward compatibility with future drivers, libGL.so
-allows drivers to register new OpenGL extension functions which weren't
-known when libGL.so was built.
-
-The register_extensions() function in xc/lib/GL/dri/dri_glx.c is called
-as soon as libGL.so is loaded. This is done with gcc's constructor
-attribute. This mechanism will likely have to be changed for other compilers.
-
-register_extensions() loops over all local displays and screens, determines
-the DRI driver for each, and calls the driver's __driRegisterExtensions()
-function, if present.
-
-The __driRegisterExtensions() function can add new entrypoints to libGL
-by calling:
-
- GLboolean _glapi_add_entrypoint(const char *funcName, GLuint offset)
-
-The parameters are the name of the function (such as "glFoobarEXT") and the
-offset of the dispatch slot in the API dispatch table. The return value
-indicates success (GL_TRUE) or failure (GL_FALSE).
-
-_glapi_add_entrypoint() will synthesize entrypoint code in assembly
-language. Assembly languages is required since parameter passing
-can't be handled correctly using a C-based solution.
-
-The address of the new entrypoint is obtained by calling the
-glXGetProcAddressARB() function.
-
-The dispatch offset number MUST be a number allocated by SGI in the same
-manner in which new GL_* constants are allocated. Using an arbitrary
-offset number will result in many problems.
-
-
-
-Dispatch Management
-
-When a GL context is made current, the driver must install its dispatch
-table as the current dispatch table. This is done by calling
-
- void _glapi_set_dispatch(struct _glapi_table *dispatch);
-
-This will install the named dispatch table for the calling thread.
-The current dispatch table for a thread can be obtained by calling
-
- struct _glapi_table *_glapi_get_dispatch(void);
-
-For higher performance in the common single-thread case, the global
-variable _glapi_Dispatch will point to the current dispatch table.
-This variable will be NULL when in multi-thread mode.
-
-
-
-Context Management
-
-libGL.so uses the XFree86 xthreads package to manage a thread-specific
-current context pointer. See __glXGet/SetCurrentContext() in glext.c
-
-Drivers may use the _glapi_set/get_context() functions to maintain
-a private thread-specific context pointer.

-<p>
-If you want to use both Mesa and another OpenGL library in the same
-application at the same time you may find it useful to compile Mesa with
-<i>name mangling</i>.
-This results in all the Mesa functions being prefixed with
-<b>mgl</b> instead of <b>gl</b>.
-</p>
-
-<p>
-To do this, recompile Mesa with the compiler flag -DUSE_MGL_NAMESPACE.
-Add the flag to CFLAGS in the configuration file which you want to use.
-For example:
-<pre>
-CFLAGS += -DUSE_MGL_NAMESPACE

-<h1>OpenGL ES</h1>
-
-<p>Mesa implements OpenGL ES 1.1 and OpenGL ES 2.0. More informations about
-OpenGL ES can be found at <a href="http://www.khronos.org/opengles/"
-target="_parent"> http://www.khronos.org/opengles/</a>.</p>
-
-<p>OpenGL ES depends on a working EGL implementation. Please refer to
-<a href="egl.html">Mesa EGL</a> for more information about EGL.</p>
-
-<h2>Build the Libraries</h2>
-<ol>
-<li>Run <code>configure</code> with <code>--enable-gles-overlay</code> and enable the Gallium driver for your hardware.</li>
-<li>Build and install Mesa as usual.</li>
-</ol>
-
-Alternatively, if XCB-DRI2 is installed on the system, one can use
-<code>egl_dri2</code> EGL driver with OpenGL|ES-enabled DRI drivers
-
-<ol>
-<li>Run <code>configure</code> with <code>--enable-gles1 --enable-gles2</code>.</li>
-<li>Build and install Mesa as usual.</li>
-</ol>
-
-<p>Both methods will install libGLESv1_CM, libGLESv2, libEGL, and one or more
-EGL drivers for your hardware.</p>
-
-<h2>Run the Demos</h2>
-
-<p>There are some demos in <code>progs/egl/</code>. You can use them to test
-your build. For example,</p>
-
-<pre>
- $ cd progs/egl/eglut
- $ make
- $ cd ../opengles1
- $ make
- $ ./torus_x11
-</pre>

-<table border="1" style="text-align: center;">
- <tr><td>Library Name</td><td>Used By</td><td>Enabled</td><td>OpenGL</td><td>OpenGL ES 1.x</td><td>OpenGL ES 2.x</td></tr>
- <tr><td><code>libmesa.a</td><td>Classic DRI drivers</td><td>y</td><td>y</td><td>--enable-gles1</td><td>--enable-gles2</td></tr>

-</table>
-
-<h3>Dispatch Table</h3>
-
-<p>OpenGL ES has an additional indirection when dispatching fucntions</p>
-
-<pre>
- Mesa: glFoo() --> _mesa_Foo()
- OpenGL ES: glFoo() --> _es_Foo() --> _mesa_Foo()
-</pre>
-
-<p>The indirection serves several purposes</p>
-
-<ul>
-<li>When a function is in Mesa and the type matches, it checks the arguments and calls the Mesa function.</li>
-<li>When a function is in Mesa but the type mismatches, it checks and converts the arguments before calling the Mesa function.</li>
-<li>When a function is not available in Mesa, or accepts arguments that are not available in OpenGL, it provides its own implementation.</li>
-</ul>
-
-<p>Other than the last case, OpenGL ES uses <code>APIspec.xml</code> to generate functions to check and/or converts the arguments.</p>

-
-<BODY>
-
-<H1>Off-screen Rendering</H1>
-
-
-<p>
-Mesa's off-screen rendering interface is used for rendering into
-user-allocated blocks of memory.
-That is, the GL_FRONT colorbuffer is actually a buffer in main memory,
-rather than a window on your display.
-There are no window system or operating system dependencies.
-One potential application is to use Mesa as an off-line, batch-style renderer.
-</p>
-
-<p>
-The <B>OSMesa</B> API provides three basic functions for making off-screen
-renderings: OSMesaCreateContext(), OSMesaMakeCurrent(), and
-OSMesaDestroyContext(). See the Mesa/include/GL/osmesa.h header for
-more information about the API functions.
-</p>
-
-<p>
-There are several examples of OSMesa in the <code>progs/osdemos/</code>
-directory.
-</p>
-
-
-<H2>Deep color channels</H2>
-
-<p>
-For some applications 8-bit color channels don't have sufficient
-precision.
-OSMesa supports 16-bit and 32-bit color channels through the OSMesa interface.
-When using 16-bit channels, channels are GLushorts and RGBA pixels occupy
-8 bytes.
-When using 32-bit channels, channels are GLfloats and RGBA pixels occupy
-16 bytes.
-</p>
-
-<p>
-Before version 6.5.1, Mesa had to be recompiled to support exactly
-one of 8, 16 or 32-bit channels.
-With Mesa 6.5.1, Mesa can be compiled for either 8, 16 or 32-bit channels
-and render into any of the smaller size channels.
-For example, if Mesa's compiled for 32-bit channels, you can also render
-16 and 8-bit channel images.
-</p>
-
-<p>
-To build Mesa/OSMesa for 16 and 8-bit color channel support:
-<pre>
- make realclean
- make linux-osmesa16
-</pre>
-
-<p>
-To build Mesa/OSMesa for 32, 16 and 8-bit color channel support:
-<pre>
- make realclean
- make linux-osmesa32
-</pre>
-
-<p>
-You'll wind up with a library named libOSMesa16.so or libOSMesa32.so.
-Otherwise, most Mesa configurations build an 8-bit/channel libOSMesa.so library
-by default.
-</p>
-
-<p>
-If performance is important, compile Mesa for the channel size you're
-most interested in.
-</p>
-
-<p>
-If you need to compile on a non-Linux platform, copy Mesa/configs/linux-osmesa16
-to a new config file and edit it as needed. Then, add the new config name to
-the top-level Makefile. Send a patch to the Mesa developers too, if you're
-inclined.

-<BODY>
-
-<H1>Performance Tips</H1>
-
-<p>
-Performance tips for software rendering:
-</P>
-<ol>
-
-<li> Turn off smooth shading when you don't need it (glShadeModel)
-<li> Turn off depth buffering when you don't need it.
-<li> Turn off dithering when not needed.
-<li> Use double buffering as it's often faster than single buffering
-<li> Compile in the X Shared Memory extension option if it's supported
- on your system by adding -DSHM to CFLAGS and -lXext to XLIBS for
- your system in the Make-config file.
-<li> Recompile Mesa with more optimization if possible.
-<li> Try to maximize the amount of drawing done between glBegin/glEnd pairs.
-<li> Use the MESA_BACK_BUFFER variable to find best performance in double
- buffered mode. (X users only)
-<li> Optimized polygon rasterizers are employed when:
- rendering into back buffer which is an XImage
- RGB mode, not grayscale, not monochrome
- depth buffering is GL_LESS, or disabled
- flat or smooth shading
- dithered or non-dithered
- no other rasterization operations enabled (blending, stencil, etc)
-<li> Optimized line drawing is employed when:
- rendering into back buffer which is an XImage
- RGB mode, not grayscale, not monochrome
- depth buffering is GL_LESS or disabled
- flat shading
- dithered or non-dithered
- no other rasterization operations enabled (blending, stencil, etc)
-<li> Textured polygons are fastest when:
- using a 3-component (RGB), 2-D texture
- minification and magnification filters are GL_NEAREST
- texture coordinate wrap modes for S and T are GL_REPEAT
- GL_DECAL environment mode
- glHint( GL_PERSPECTIVE_CORRECTION_HINT, GL_FASTEST )
- depth buffering is GL_LESS or disabled
-<li> Lighting is fastest when:
- Two-sided lighting is disabled
- GL_LIGHT_MODEL_LOCAL_VIEWER is false
- GL_COLOR_MATERIAL is disabled
- No spot lights are used (all GL_SPOT_CUTOFFs are 180.0)
- No local lights are used (all position W's are 0.0)
- All material and light coefficients are >= zero
-<li> XFree86 users: if you want to use 24-bit color try starting your
- X server in 32-bit per pixel mode for better performance. That is,
- start your X server with
- startx -- -bpp 32
- instead of
- startx -- -bpp 24
-<li> Try disabling dithering with the MESA_NO_DITHER environment variable.
- If this env var is defined Mesa will disable dithering and the
- command glEnable(GL_DITHER) will be ignored.

-<h2>Shared library numbering</h2>
-<p>
-Mesa 6.5.3 supports the OpenGL 2.0/2.1 API. However, the (unix)
-shared library version is still 1.5 (i.e. libGL.so.1.5.xxxxxx).
-Bumping the shared library version to 2.x would cause linking problems
-with existing OpenGL applications. Since OpenGL 2.x is backward
-compatible with OpenGL 1.x the shared library version number doesn't
-have to be incremented (which would indicate an incompatible ABI).
-</p>
-<p>
-Other OpenGL vendors name their OpenGL 2.x libraries libGL.so.1.0.xxxxx
-for the same reason.
-</p>
-
-
-
-<h2>New features</h2>
-<ul>
-<li>OpenGL 2.0 and 2.1 API support.
-<li>Entirely new Shading Language code generator. See the
-<a href="shading.html">Shading Language</a> page for more information.
-<li>Much faster software execution of vertex, fragment shaders.
-<li>New vertex buffer object (vbo) infrastructure
-<li>Updated glext.h file (version 39)
-<li>Updated glxext.h file (version 19)
-<li>GL_MAX_DRAWBUFFERS is now 4 (software rendering) so
- "multiple render targets" are really supported.
-</ul>
-
-<h2>Bug fixes</h2>
-<ul>
-<li>Fog was errantly applied when a fragment shader was enabled (bug 9346)
-<li>glPush/PopClientAttrib didn't handle VBO bindings correctly (bug 9445)
-<li>With 32-bit Z buffer, the fragment Z of lines and points was sometimes wrong.
-<li>GL_POST_CONVOLUTION_ALPHA_BIAS/SCALE was broken.
-<li>1D convolution state could effect 2D image transfers
-<li>Overlapping glCopyPixels with negative Y zoom didn't work (bug 10521)
-<li>Fixed a number of framebuffer/renderbuffer reference counting bugs
-<li>Fixed a few bugs in software-emulated alpha planes
-<li>Assorted minor bug fixes in glCopy/DrawPixels, glPixelZoom, etc.
-<li>Assorted DRI driver bug fixes.
-<li>Fixed a number of bugs that prevented "depth-peeling" rendering from working.
-</ul>
-
-
-<h2>Internal code changes</h2>
-<ul>
-<li>Old array_cache module replaced by new vbo module. All geometry
-rendering is now cast in the form of vertex buffer objects.
-<li>Massive changes to the Shading Language compiler and related state.
-<li>Vertex/fragment shaders are compiled into GPU instructions and
-programs very similar to GL_ARB_vertex/fragment_program.
-<li>Vertex and fragment programs are executed with the same code now.
-<li>The SSE-optimized vertex program path has been removed since it didn't
-support more than 12 temp registers, didn't support branching/looping, etc.
-</ul>
-
-
-<h2>To Do (someday) items</h2>
-<ul>
-<li>Switch to freeglut
-<li>Fix linux-glide target/driver.
-<li>Improved lambda and derivative calculation for frag progs.

-<h2>New Features</h2>
-<ul>
-<li>OpenGL Shading language support
-<br>
- This includes the GL_ARB_shader_objects, GL_ARB_shading_language_100,
- GL_ARB_vertex_shader and GL_ARB_fragment_shader extensions. Most of
- the work was done by Michal Krol.
- There's probably a fair number of bugs since this is a pretty large,
- complicated body of code.
-<br>
- The OpenGL 2.0 interface to these features will be implemented in a
- future version of Mesa,
-
-<li>GL_EXT_timer_query
-<br>
- Used to measure the time of OpenGL operations at high precision.
- Only supported in the software/Xlib driver at this time.
-
-<li>GL_EXT_packed_depth_stencil
-<br>
- Defines a new GL_DEPTH_STENCIL_EXT pixel format.
-
-<li>GL_EXT_framebuffer_blit
-<br>
- A simplified glCopyPixels-like feature for copying pixel rectangles.
-
-<li>GL_ARB_half_float_pixel
-<br>
- Adds a new half-precision floating point format for image transfers,
- such as for glDrawPixels, glReadPixels, glTexImage, etc.
-</ul>
-
-<h2>Changes</h2>
-<ul>
-<li>removed GL_HP_occlusion_test (use GL_ARB_occlusion_query instead)
-<li>removed GL_SGIX/SGIS_pixel_texture extensions
-</ul>
-<h2>Bug fixes</h2>
-<ul>
-<li>fixed glxcontextmodes.c datatype problem (bug 5835)
-<li>fixed aix-gcc build/install bugs (bug 5874)
-<li>fixed some bugs in texture env program generation
-<li>glXCopyContext() didn't handle texture object bindings properly
-<li>glXCopyContext() didn't copy all lighting state
-<li>fixed FreeBSD config (Pedro Giffuni)
-<li>fixed some minor framebuffer object bugs
-<li>replaced dprintf() with _glu_printf() in GLU (bug 6244)
-<li>fixed a number of thread safety bugs/regressions
-<li>fixed a number of GLU tesselator bugs (John Shell, bug 6339)
-<li>paletted texturing was broken w/ floating point palettes (K. Schultz)
-<li>lots of assorted framebuffer object bug fixes
-</ul>
-
-
-<h2>Known Issues</h2>
-<ul>
-<li>Rendering to depth textures will not work. Rendering to GL_DEPTH_STENCIL
-textures should work.
-</ul>
-
-
-<h2>Driver Interface Changes</h2>
-<ul>
-<li>Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by
-the two-sided versions: Driver.Stencil*Separate().
-<li>Render-to-texture: The functions for rendering to textures have changed.
-</ul>
-
-
-<h2>To Do (someday) items</h2>
-<ul>
-<li>Switch to freeglut
-<li>Increase MAX_DRAWBUFFERS
-<li>Fix linux-glide target/driver.
-<li>Fix lambda calculation for frag progs.
-</ul>
-

-<H1>Mesa 7.1 Release Notes / August 26, 2008</H1>
-
-<p>
-Mesa 7.1 is a new development release.
-There have been many internal code changes since Mesa 7.0.x.
-It should be relatively stable, but those who are especially concerned about
-stability should wait for Mesa 7.2 or use Mesa 7.0.4 (the previous stable
-release).
-</p>
-</>
-Note that this version of Mesa does not use the GEM memory manager.
-The master branch of git uses GEM.
-</p>
-<p>
-DRM version 2.3.1 should be used with Mesa 7.1
-</p>

-<h2>New features</h2>
-<ul>
-<li>autoconf-based configuration (and clean-up of Makefiles)
-<li>Assorted DRI driver enhancements
-<li>Reduced dependencies between X server and Mesa
-<li>GL_EXT_texture_from_pixmap extension for Xlib driver
-<li>Support for the GL shading language with i965 driver (implemented by Intel)
-<li>ATI R500 series support (Radeon X1300–X1950) in r300 DRI driver
-</ul>
-
-
-<h2>Bug fixes</h2>
-<ul>
-<li>Numerous GLSL fixes
-<li>Fixed some error code/detection bugs in the GLSL-related API functions
-<li>Lots of DRI driver fixes.
-</ul>
-
-
-<h2>To Do (someday) items</h2>
-<ul>
-<li>Remove the MEMCPY() and _mesa_memcpy() wrappers and just use memcpy().
-Probably do the same for malloc, calloc, etc.
-The wrappers were useful in the past for memory debugging but now we
-have valgrind. Not worried about SunOS 4 support anymore either...
-<li>Switch to freeglut
-<li>Fix linux-glide target/driver.
-<li>Improved lambda and derivative calculation for frag progs.

-<H1>Mesa 7.10 Release Notes / January 7, 2011</H1>
-
-<p>
-Mesa 7.10 is a new development release.
-People who are concerned with stability and reliability should stick
-with a previous release or wait for Mesa 7.10.1.
-</p>
-<p>
-Mesa 7.10 implements the OpenGL 2.1 API, but the version reported by
-glGetString(GL_VERSION) depends on the particular driver being used.
-Some drivers don't support all the features required in OpenGL 2.1.
-</p>
-<p>
-See the <a href="install.html">Compiling/Installing page</a> for prerequisites
-for DRI hardware acceleration.

-<H1>Mesa 7.2 Release Notes / 20 September 2008</H1>
-
-<p>
-Mesa 7.2 is a stable release fixing bugs found in 7.1, which was a
-new development release.
-</p>
-<p>
-Mesa 7.2 implements the OpenGL 2.1 API, but the version reported by
-glGetString(GL_VERSION) depends on the particular driver being used.
-Some drivers don't support all the features required in OpenGL 2.1.
-</p>
-<p>
-Note that this version of Mesa does not use the GEM memory manager.
-The master branch of git uses GEM.
-The prototype DRI2 code that was in 7.1 has also been removed.
-</p>
-<p>
-DRM version 2.3.1 should be used with Mesa 7.2
-</p>

-<li>i965 driver: added support for G41 chipset (Intel)
-</ul>
-
-
-<h2>Bug fixes</h2>
-<ul>
-<li>Fixed display list bug involving primitives split across lists (bug 17564)
-<li>Fixed some issues with glBindAttribLocation()
-<li>Fixed crash in _tnl_InvalidateState() found with Amira (bug 15834)
-<li>Assorted bug fixes for Ming build

-<h2>To Do (someday) items</h2>
-<ul>
-<li>Remove the MEMCPY() and _mesa_memcpy() wrappers and just use memcpy().
-Probably do the same for malloc, calloc, etc.
-The wrappers were useful in the past for memory debugging but now we
-have valgrind. Not worried about SunOS 4 support anymore either...
-<li>Switch to freeglut
-<li>Fix linux-glide target/driver.
-<li>Improved lambda and derivative calculation for frag progs.

-<H1>Mesa 7.5 Release Notes / 17 July 2009</H1>
-
-<p>
-Mesa 7.5 is a new development release.
-People who are concerned with stability and reliability should stick
-with the 7.4.x branch or wait for Mesa 7.5.1.
-</p>
-<p>
-The main new feature of Mesa 7.5 is the
-<a href="http://wiki.freedesktop.org/wiki/Software/gallium"
-target="_parent">Gallium3D</a> infrastructure.
-</p>
-<p>

-</p>
-<p>
-See the <a href="install.html">Compiling/Installing page</a> for prerequisites
-for DRI hardware acceleration.
-</p>
-<p>
-Note that the Mesa project is no longer using odd/even version numbers
-to indicate development/stable releases.
-The so-called development releases have been fairly stable.
-If you're especially concerned with stability you should probably look for
-"point" releases such as 7.5.1 which will be a bug-fix release.

-<h2>New features</h2>
-<ul>
-<li>Gallium3D - this is the new architecture for OS-independent and
- API-independent 3D drivers.
- Gallium3D is intended for GPUs that fully support vertex/fragment shaders.
- The Gallium3D drivers currently included are:
- <ul>
- <li>softpipe - a software/reference driver
- <li>i915 - Intel 915/945 driver
- <li><a href="cell.html">Cell</a> - IBM/Sony/Toshiba Cell processor driver
- <li>nouveau (for NVIDIA GPUs) and R300 for (AMD/ATI R300).
- <b>PLEASE NOTE: these drivers are incomplete and still under development.
- It's probably NOT worthwhile to report any bugs unless you have patches.
- </b>
- </ul>
-<li>GL_ARB_framebuffer_object extension (software drivers, i965 driver)
-<li>Reworked two-sided stencil support.
-This allows a driver to support all three variations of two-sided stencil
-including GL_ATI_separate_stencil, GL_EXT_stencil_two_side and OpenGL 2.0
-<li>GL_EXT_vertex_array_bgra extension (software drivers, i965 driver)
-<li>GL_NV_texture_env_combine4 extension (software drivers, i965/i915 drivers)
-<li>GL_EXT_texture_swizzle extension (software drivers, i965 driver)
-<li>Updated SPARC assembly optimizations (David S. Miller)
-<li>Initial support for separate compilation units in GLSL compiler.
-<li>Increased max number of generic GLSL varying variables to 16 (formerly 8).
-<li>GLSL linker now detects when too many varying variables are used.
-<li>Optimize-out redundant glMaterial and glShadeModel calls in display lists
-<li>Fixed gl_TextureMatrix[i][j] array indexing bug in GLSL compiler.
-</ul>
-
-
-<h2>Bug fixes</h2>
-<ul>
-<li>Lots of i965 driver bug fixes
-<li>Fixed some GLSL preprocessor bugs
-<li>GLSL: continue inside of a for-loop didn't work
-</ul>
-
-
-<h2>Changes</h2>
-<ul>
-<li>Remove support for GL_SGIX_shadow, GL_SGIX_shadow_ambient and
-GL_SGIX_depth_texture extensions. Superseded by the ARB versions.
-<li>Omitted some old Mesa demos from the release tarballs, added some others.
-</ul>

-<H1>Mesa 7.9 Release Notes / October 4, 2010</H1>
-
-<p>
-Mesa 7.9 is a new development release.
-People who are concerned with stability and reliability should stick
-with a previous release or wait for Mesa 7.9.1.
-</p>
-<p>
-Mesa 7.9 implements the OpenGL 2.1 API, but the version reported by
-glGetString(GL_VERSION) depends on the particular driver being used.
-Some drivers don't support all the features required in OpenGL 2.1.
-</p>
-<p>
-See the <a href="install.html">Compiling/Installing page</a> for prerequisites
-for DRI hardware acceleration.
-</p>

-<h2>New features</h2>
-<ul>
-<li>New, improved GLSL compiler written by Intel.
- See the <a href="shading.html"> Shading Language</a> page for
- more information.
-<li>New, very experimental Gallium driver for R600-R700 Radeons.
-<li>Support for AMD Evergreen-based Radeons (HD 5xxx)
-<li>GL_EXT_timer_query extension (i965 driver and softpipe only)
-<li>GL_EXT_framebuffer_multisample extension (intel drivers, MAX_SAMPLES = 1)
-<li>GL_ARB_texture_swizzle extension (alias of GL_EXT_texture_swizzle)
-<li>GL_ARB_draw_elements_base_vertex, GL_ARB_fragment_program_shadow,
- GL_ARB_window_pos, GL_EXT_gpu_program_parameters,
- GL_ATI_texture_env_combine3, GL_MESA_pack_invert, and GL_OES_EGL_image
- extensions in Gallium drivers
-<li>GL_ARB_depth_clamp and GL_NV_depth_clamp extensions (in nv50 and r600
- Gallium drivers)
-<li>GL_ARB_half_float_vertex extension (in nvfx, r300, r600, softpipe,
- and llvmpipe Gallium drivers)
-<li>GL_EXT_draw_buffers2 (in nv50, r600, softpipe, and llvmpipe Gallium
- drivers)
-<li>GL_EXT_texture_swizzle (in nvfx, r300, r600, softpipe, and llvmpipe
- Gallium drivers)
-<li>GL_ATI_texture_mirror_once (in nvfx, nv50, r300, r600, softpipe, and
- llvmpipe Gallium drivers)
-<li>GL_NV_conditional_render (in r300 Gallium driver)
-<li>Initial "signs of life" support for Sandybridge hardware in i965 DRI
- driver.
-</ul>
-
-
-<h2>Bug fixes</h2>
-<p>This list is likely incomplete.</p>
-<ul>

-<h1>Code Repository</h1>
-
-<p>
-Mesa uses <a href="http://git.or.cz/"target="_parent">git</a>
-as its source code management system.
-</p>
-
-The master git repository is hosted on
-<a href="http://www.freedesktop.org" target="_parent">freedesktop.org</a>.
-</p>
-
-<p>
-You may access the repository either as an
-<a href="#anonymous">anonymous user</a> (read-only) or as a
-<a href="#developer">developer</a>
-(read/write).
-</p>
-
-<p>
-You may also
-<a href="http://gitweb.freedesktop.org/?p=mesa/mesa.git"
-target="_parent">browse the main Mesa git repository</a> and the
-<a href="http://cgit.freedesktop.org/mesa/demos"
-target="_parent">Mesa demos and tests git repository</a>.
-</p>
-
-
-<a name="anonymous">
-<H2>Anonymous git Access</H2>
-
-<p>
-To get the Mesa sources anonymously (read-only):
-</p>
-
-<ol>
-<li>Install the git software on your computer if needed.<br><br>
-<li>Get an initial, local copy of the repository with:
- <pre>
- git clone git://anongit.freedesktop.org/git/mesa/mesa
- </pre>
-<li>Later, you can update your tree from the master repository with:
- <pre>
- git pull origin
- </pre>
-<li>If you also want the Mesa demos/tests repository:
- <pre>
- git clone git://anongit.freedesktop.org/git/mesa/demos
- </pre>
-</ol>
-
-
-<a name="developer">
-<H2>Developer git Access</H2>
-
-<p>
-Mesa developers need to first have an account on
-<a href="http://www.freedesktop.org" target="_parent">freedesktop.org</a>.
-To get an account, please ask Brian or the other Mesa developers for
-permission.
-Then, if there are no objections, follow this
-<a href="http://www.freedesktop.org/wiki/AccountRequests" target="_parent">
-procedure</a>.
-</p>
-
-<p>
-Once your account is established:
-</p>
-
-<ol>
-<li>Install the git software on your computer if needed.<br><br>
-<li>Get an initial, local copy of the repository with:
- <pre>
- git clone git+ssh://username@git.freedesktop.org/git/mesa/mesa
- </pre>
- Replace <em>username</em> with your actual login name.<br><br>
-<li>Later, you can update your tree from the master repository with:
- <pre>
- git pull origin
- </pre>
-<li>If you also want the Mesa demos/tests repository:
- <pre>
- git clone git+ssh://username@git.freedesktop.org/git/mesa/demos

-
-<H2>Windows Users</H2>
-
-<p>
-If you're <a href="http://git.or.cz/gitwiki/WindowsInstall" target="_parent">
-using git on Windows</a> you'll want to enable automatic CR/LF conversion in
-your local copy of the repository:
-</p>
-<pre>
- git config --global core.autocrlf true
-</pre>
-
-<p>
-This will cause git to convert all text files to CR+LF on checkout,
-and to LF on commit.
-</p>
-<p>
-Unix users don't need to set this option.
-</p>
-<br>
-
-
-<a name="developer">
-<H2>Development Branches</H2>
-
-<p>
-At any given time, there may be several active branches in Mesa's
-repository.
-Generally, the trunk contains the latest development (unstable)
-code while a branch has the latest stable code.
-</p>
-
-<p>
-The command <code>git-branch</code> will list all available branches.
-</p>
-
-<p>
-Questions about branch status/activity should be posted to the
-mesa3d-dev mailing list.
-</p>
-
-<H2>Developer Git Tips</H2>
-
-<ol>
-<li>Setting up to edit the master branch
-<p>
-If you try to do a pull by just saying<code> git pull </code>
-and git complains that you have not specified a
-branch, try:
-<pre>
- git config branch.master.remote origin
- git config branch.master.merge master
-</pre>
-Otherwise, you have to say<code> git pull origin master </code>
-each time you do a pull.
-</p>
-<li>Small changes to master
-<p>
-If you are an experienced git user working on substancial modifications,
-you are probably
-working on a separate branch and would rebase your branch prior to
-merging with master.
-But for small changes to the master branch itself,
-you also need to use the rebase feature in order to avoid an
-unnecessary and distracting branch in master.
-</p>
-<p>
-If it has been awhile since you've done the initial clone, try
-<pre>
- git pull
-</pre>
-to get the latest files before you start working.
-</p>
-<p>
-Make your changes and use
-<pre>
- git add <files to commit>
- git commit
-</pre>
-to get your changes ready to push back into the fd.o repository.
-</p>
-<p>
-It is possible (and likely) that someone has changed master since
-you did your last pull. Even if your changes do not conflict with
-their changes, git will make a fast-forward
-merge branch, branching from the point in time
-where you did your last pull and merging it to a point after the other changes.
-</p>
-<p>
-To avoid this,
-<pre>
- git pull --rebase
- git push
-</pre>
-If you are familiar with CVS or similar system, this is similar to doing a
-<code> cvs update </code> in order to update your source tree to
-the current repository state, instead of the time you did the last update.
-(CVS doesn't work like git in this respect, but this is easiest way
-to explain it.)
-</br>
-In any case, your repository now looks like you made your changes after
-all the other changes.
-</p>
-<p>
-If the rebase resulted in conflicts or changes that could affect
-the proper operation of your changes, you'll need to investigate
-those before doing the push.
-</p>
-<p>
-If you want the rebase action to be the default action, then
-<pre>
- git config branch.master.rebase true
- git config --global branch.autosetuprebase=always
-</pre>
-<p>
-See <a href="http://www.eecs.harvard.edu/~cduan/technical/git/" target="_parent">Understanding Git Conceptually</a> for a fairly clear explanation about all of this.

-OpenGL Shading Language</a>.

-<h2>Environment Variables</h2>
-
-<p>
-The <b>MESA_GLSL</b> environment variable can be set to a comma-separated
-list of keywords to control some aspects of the GLSL compiler and shader
-execution. These are generally used for debugging.
-</p>
-<ul>
-<li><b>dump</b> - print GLSL shader code to stdout at link time
-<li><b>log</b> - log all GLSL shaders to files.
- The filenames will be "shader_X.vert" or "shader_X.frag" where X
- the shader ID.
-<li><b>nopt</b> - disable compiler optimizations
-<li><b>opt</b> - force compiler optimizations
-<li><b>uniform</b> - print message to stdout when glUniform is called
-<li><b>nopvert</b> - force vertex shaders to be a simple shader that just transforms
- the vertex position with ftransform() and passes through the color and
- texcoord[0] attributes.
-<li><b>nopfrag</b> - force fragment shader to be a simple shader that passes
- through the color attribute.
-<li><b>useprog</b> - log glUseProgram calls to stderr
-</ul>
-<p>
-Example: export MESA_GLSL=dump,nopt
-</p>
-
-
-<a name="120">
-<h2>GLSL Version</h2>
-
-<p>
-The GLSL compiler currently supports version 1.20 of the shading language.
-</p>
-
-<p>
-Several GLSL extensions are also supported:
-</p>
-<ul>
-<li>GL_ARB_draw_buffers
-<li>GL_ARB_texture_rectangle
-<li>GL_ARB_fragment_coord_conventions
-<li>GL_EXT_texture_array
-</ul>
-
-
-<a name="unsup">
-<h2>Unsupported Features</h2>
-
-<p>XXX update this section</p>
-
-<p>
-The following features of the shading language are not yet fully supported
-in Mesa:
-</p>
-
-<ul>
-<li>Linking of multiple shaders does not always work. Currently, linking
- is implemented through shader concatenation and re-compiling. This
- doesn't always work because of some #pragma and preprocessor issues.
-<li>gl_ClipVertex
-<li>The gl_Color and gl_SecondaryColor varying vars are interpolated
- without perspective correction
-</ul>
-
-<p>
-All other major features of the shading language should function.
-</p>
-
-
-<a name="notes">
-<h2>Implementation Notes</h2>
-
-<ul>
-<li>Shading language programs are compiled into low-level programs
- very similar to those of GL_ARB_vertex/fragment_program.
-<li>All vector types (vec2, vec3, vec4, bvec2, etc) currently occupy full
- float[4] registers.
-<li>Float constants and variables are packed so that up to four floats
- can occupy one program parameter/register.
-<li>All function calls are inlined.
-<li>Shaders which use too many registers will not compile.
-<li>The quality of generated code is pretty good, register usage is fair.
-<li>Shader error detection and reporting of errors (InfoLog) is not
- very good yet.
-<li>The ftransform() function doesn't necessarily match the results of
- fixed-function transformation.
-</ul>
-
-<p>
-These issues will be addressed/resolved in the future.
-</p>
-
-
-<a name="hints">
-<h2>Programming Hints</h2>
-
-<ul>
-<li>Use the built-in library functions whenever possible.
- For example, instead of writing this:
-<pre>
- float x = 1.0 / sqrt(y);
-</pre>
- Write this:
-<pre>
- float x = inversesqrt(y);
-</pre>
-</li>
-</ul>
-
-
-<a name="standalone">
-<h2>Stand-alone GLSL Compiler</h2>
-
-<p>
-The stand-alone GLSL compiler program can be used to compile GLSL shaders
-into low-level GPU code.
-</p>
-
-<p>
-This tool is useful for:
-<p>
-<ul>
-<li>Inspecting GPU code to gain insight into compilation
-<li>Generating initial GPU code for subsequent hand-tuning
-<li>Debugging the GLSL compiler itself
-</ul>
-
-<p>
-After building Mesa, the compiler can be found at src/glsl/glsl_compiler
-</p>
-
-<p>
-Here's an example of using the compiler to compile a vertex shader and
-emit GL_ARB_vertex_program-style instructions:
-</p>
-<pre>
- src/glsl/glslcompiler --dump-ast myshader.vert
-</pre>
-
-Options include
-<ul>
-<li><b>--dump-ast</b> - dump GPU code
-<li><b>--dump-hir</b> - dump high-level IR code
-<li><b>--dump-lir</b> - dump low-level IR code
-<li><b>--link</b> - ???
-</ul>
-
-
-
-
-<a name="implementation">
-<h2>Compiler Implementation</h2>
-
-<p>
-The source code for Mesa's shading language compiler is in the
-<code>src/glsl/</code> directory.
-</p>
-
-<p>
-XXX provide some info about the compiler....
-</p>
-
-<p>
-The final vertex and fragment programs may be interpreted in software
-(see prog_execute.c) or translated into a specific hardware architecture
-(see drivers/dri/i915/i915_fragprog.c for example).
-</p>
-
-<h3>Code Generation Options</h3>
-
-<p>
-Internally, there are several options that control the compiler's code
-generation and instruction selection.
-These options are seen in the gl_shader_state struct and may be set
-by the device driver to indicate its preferences:
-
-<pre>
-struct gl_shader_state
-{
- ...
- /** Driver-selectable options: */
- GLboolean EmitHighLevelInstructions;
- GLboolean EmitCondCodes;
- GLboolean EmitComments;
-};
-</pre>
-
-<ul>
-<li>EmitHighLevelInstructions
-<br>
-This option controls instruction selection for loops and conditionals.
-If the option is set high-level IF/ELSE/ENDIF, LOOP/ENDLOOP, CONT/BRK
-instructions will be emitted.
-Otherwise, those constructs will be implemented with BRA instructions.
-</li>
-
-<li>EmitCondCodes
-<br>
-If set, condition codes (ala GL_NV_fragment_program) will be used for
-branching and looping.
-Otherwise, ordinary registers will be used (the IF instruction will
-examine the first operand's X component and do the if-part if non-zero).
-This option is only relevant if EmitHighLevelInstructions is set.
-</li>
-
-<li>EmitComments
-<br>
-If set, instructions will be annoted with comments to help with debugging.
-Extra NOP instructions will also be inserted.
-</br>
-
-</ul>
-
-
-<a name="validation">
-<h2>Compiler Validation</h2>
-
-<p>
-Developers working on the GLSL compiler should test frequently to avoid
-regressions.
-</p>
-
-<p>
-The <a href="http://people.freedesktop.org/~nh/piglit/">Piglit</a> project
-has many GLSL tests and the
-<a href="http://glean.sf.net" target="_parent">Glean</a> glsl1 test
-tests GLSL features.
-</p>
-
-<p>
-The Mesa demos repository also has some good GLSL tests.

-<h1>2. Primitive Specification</h1>
-<h2>2.1 glBegin, glEnd and glVertex Commands</h2>
-The basic rendering primitives are points, lines and triangles.
- Quadrilaterals and polygons are composed of triangles.
- Primitives are drawn with the <span style="font-weight: bold;">glBegin</span>
-and <span style="font-weight: bold;">glEnd</span> commands and a subset
-of the <span style="font-weight: bold;">glVertex</span> commands:<br>
-<br>
-<div style="margin-left: 40px;">void <span style="font-weight: bold;">glBegin</span>(GLenum<span
- style="font-style: italic;">mode</span>)<br>
-void <span style="font-weight: bold;">glEnd</span>(void)<br>
-<br>
-void <span style="font-weight: bold;">glVertex2f</span>(GLfloat <span
- style="font-style: italic;">x</span>, GLfloat <span
- style="font-style: italic;">y</span>)<br>
-void <span style="font-weight: bold;">glVertex2fv</span>(const GLfloat
-*<span style="font-style: italic;">v</span>)<br>
-void <span style="font-weight: bold;">glVertex3f</span>(GLfloat <span
- style="font-style: italic;">x</span>, GLfloat <span
- style="font-style: italic;">y</span>, GLfloat <span
- style="font-style: italic;">z</span>)<br>
-void <span style="font-weight: bold;">glVertex3fv</span>(const GLfloat
-*<span style="font-style: italic;">v</span>)<br>
-</div>
-<br>
-The <span style="font-style: italic;">mode</span> parameter to <span
- style="font-weight: bold;">glBegin</span> may be one of the following<br>
-<br>
-<div style="margin-left: 40px;">GL_POINTS - a series of individual
-points<br>
-GL_LINES - a series of disjoint line segments<br>
-GL_LINE_STRIP - series of connected line segments<br>
-GL_LINE_LOOP - a closed loop of line segments<br>
-GL_TRIANGLES - a series of individual triangles<br>
-GL_TRIANGLE_STRIP - a connected strip of triangles<br>
-GL_TRIANGLE_FAN - a sequence of triangles all sharing a common vertex<br>
-GL_QUADS - a sequence of individual quadrilaterals<br>
-GL_QUAD_STRIP - a connected strip of quadrilaterals<br>
-GL_POLYGON - a closed, convex polygon<br>
-<br>
-</div>
-<br>
-The <span style="font-weight: bold;">glVertex</span> commands take two
-or three floating point coordinates, or a pointer to an array of two or
-three floating point coordinates. Vertices are actually 4-element
-homogeneous coordinates. The fourth component, unspecified by the
-subset's <span style="font-weight: bold;">glVertex</span> commands, is
-one.<br>
-<br>
-<span style="font-weight: bold;"></span>
-<h2>2.2 Other Per-vertex Commands<br>
-</h2>
-The <span style="font-weight: bold;">glColor</span> and <span
- style="font-weight: bold;">glTexCoord</span> commands may be used to
-specify colors and texture coordinates for each vertex:<br>
-<br>
-<div style="margin-left: 40px;">void <span style="font-weight: bold;">glColor3f</span>(GLfloat<span
- style="font-style: italic;">red</span>, GLfloat <span
- style="font-style: italic;">green</span>, GLfloat <span
- style="font-style: italic;">blue</span>)<br>
-void <span style="font-weight: bold;">glColor3fv</span>(const GLfloat *<span
- style="font-style: italic;">rgb</span>)<br>
-void <span style="font-weight: bold;">glColor4f</span>(GLfloat <span
- style="font-style: italic;">red,</span> GLfloat <span
- style="font-style: italic;">green,</span> GLfloat <span
- style="font-style: italic;">blue,</span> GLfloat <span
- style="font-style: italic;">alpha</span>)<br>
-void <span style="font-weight: bold;">glColor4fv</span>(const GLfloat *<span
- style="font-style: italic;">rgba</span>)<br>
-void <span style="font-weight: bold;">glTexCoord2f</span>(GLfloat <span
- style="font-style: italic;">s</span>, GLfloat<span
- style="font-style: italic;"> t</span>)<br>
-void <span style="font-weight: bold;">glTexCoord2fv</span>(const
-GLfloat *<span style="font-style: italic;">c</span>)<br>
-<br>
-</div>
-The <span style="font-weight: bold;">glColor</span> commands specify
-the color and optionally, the alpha value, for subsequent vertices.
- For the <span style="font-weight: bold;">glColor3</span> commands,
-alpha is set to one.<br>
-<br>
-The <span style="font-weight: bold;">glTexCoord2</span> commands
-specify the texture coordinate for subsequent vertices. Texture
-coordinates are actually four-component coordinates: (s, t, r, q).
- The <span style="font-weight: bold;">glTexCoord2</span> commands
-set s and t explicitly. The r and q components are zero and one,
-respectively.<br>
-<br>
-<span style="font-weight: bold;"></span>Only <span
- style="font-weight: bold;">glVertex, glColor</span> and <span
- style="font-weight: bold;">glTexCoord</span> commands are allowed
-between <span style="font-weight: bold;">glBegin</span> and <span
- style="font-weight: bold;">glEnd.</span> Calling any other
-command between <span style="font-weight: bold;">glBegin</span> and <span
- style="font-weight: bold;">glEnd</span> will result in the error
-GL_INVALID_OPERATION.<br>

-<h1>3. Coordinate Transformation</h1>
-<h2>3.1 Vertex Transformation</h2>
-Vertex coordinates are transformed by the current modelview and

-</div>
-<br>
-The <span style="font-weight: bold;">glMatrixMode</span> command
-specifies the <span style="font-style: italic;">current matrix.</span>
- The mode parameter may be GL_MODELVIEW or GL_PROJECTION to specify
-the modelview matrix or projection matrix. Subsequent matrix
-commands will effect the current matrix. Also associated with the
-modelview and projection matrices are a modelview matrix stack and
-projection matrix stack.<br>
-<br>
-The <span style="font-weight: bold;">glLoadIdentity</span> command
-replaces the current matrix with the identity matrix. The matrix
-elements are specified in column-major order.<br>
-<br>
-The <span style="font-weight: bold;">glPushMatrix</span> command pushes
-a copy of the current matrix onto either the modelview matrix stack or
-the projection matrix stack. The <span style="font-weight: bold;">glPopMatrix</span>
-command replaces the current matrix with a copy of the top matrix off
-the modelview matrix stack or projection matrix stack, the pops the
-stack. Matrix stacks are useful for traversing and rendering
-hierarchical models.<br>
-<br>
-The <span style="font-weight: bold;">glMultMatrixf</span> command
-post-multiplies the current matrix by the specified matrix. The
-matrix elements are specified in column-major order.<br>
-<br>
-The <span style="font-weight: bold;">glRotatef</span> command
-post-multiplies the current matrix by a rotation matrix defined by the
-angle and rotation axis defined by x, y and z.<br>
-<br>
-The <span style="font-weight: bold;">glTranslatef</span> command
-post-multiplies the current matrix by a translation matrix defined by
-the <span style="font-style: italic;">x</span>, <span
- style="font-style: italic;">y</span> and <span
- style="font-style: italic;">z</span> translation parameters.<br>
-<span style="font-weight: bold;"></span><br>
-The <span style="font-weight: bold;">glScalef</span> command
-post-multiplies the current matrix by a scaling matrix defined by the <span
- style="font-style: italic;">x</span>, <span
- style="font-style: italic;">y</span> and <span
- style="font-style: italic;">z</span> scale factors.<br>
-<span style="font-weight: bold;"></span><br>
-The <span style="font-weight: bold;">glFrustum</span> command
-post-multiplies the current matrix by a perspective projection matrix.
- The <span style="font-style: italic;">near</span> and <span
- style="font-style: italic;">far</span> values specify the position of
-the hither and yon Z-axis clipping planes. The <span
- style="font-style: italic;">left, right, bottom</span> and <span
- style="font-style: italic;">top</span> parameters are the X and Y
-extents at the near clipping plane. <span
- style="font-weight: bold;">glFrustum</span> is normally used to modify
-the projection matrix.<br>
-<br>
-The <span style="font-weight: bold;">glOrtho</span> command
-post-multiplies the current matrix by an orthographic projection matrix.
- The <span style="font-style: italic;">near</span> and <span
- style="font-style: italic;">far</span> values specify the position of
-the hither and yon Z-axis clipping planes. The <span
- style="font-style: italic;">left, right, bottom</span> and <span
- style="font-style: italic;">top</span> parameters specify the X and
-Y-axis clipping planes. <span style="font-weight: bold;">glOrtho</span>
-is normally used to modify the projection matrix.<br>
-<br>
-The <span style="font-weight: bold;">glViewport</span> command
-specifies the mapping of coordinates from normalized device coordinates
-to window coordinates. The <span style="font-style: italic;">x</span>
-and <span style="font-style: italic;">y</span> parameters specify the
-viewport's lower-left corner in the window and the <span
- style="font-style: italic;">width</span> and <span
- style="font-style: italic;">height</span> parameters specify the size
-of the viewport. <span style="font-weight: bold;">glViewport</span>
-does not effect the current matrix.<br>
-<br>
-A coordinate transformed to window coordinates is hereafter known as (x<sub>w</sub>,
-y<sub>w</sub>, z<sub>w</sub>).<br>
-<br>
-<h2>3.2 Clipping</h2>
-View-volume clipping automatically discards or trims primitives which
-lie completely or partially outside of the view volume specified by <span
- style="font-weight: bold;">glFrustum</span> and <span
- style="font-weight: bold;">glOrtho</span>. Note that the <span
- style="font-weight: bold;">glViewport</span> command does not define a
-clipping region.<br>
-<br>
-Clipping occurs in <span style="font-style: italic;">clip coordinate
-space - </span>the coordinates produced after applying the projection
-matrix.<br>
-<br>
-<h2>3.3 Current Raster Position</h2>
-The current raster position specifies the location for drawing images
-with <span style="font-weight: bold;">glBitmap.</span> The current
-raster position is set with the commands:<br>
-<br>
-<div style="margin-left: 40px;">void <span style="font-weight: bold;">glRasterPos2f</span>(GLfloat<span
- style="font-style: italic;">x</span>, GLfloat <span
- style="font-style: italic;">y</span>)<br>
-void <span style="font-weight: bold;">glRasterPos2fv</span>(const
-GLfloat *<span style="font-style: italic;">v</span>)<br>
-void <span style="font-weight: bold;">glRasterPos2i</span>(GLint <span
- style="font-style: italic;">x</span>, GLint <span
- style="font-style: italic;">y</span>)<br>
-void <span style="font-weight: bold;">glRasterPos2iv</span>(const
-GLint *<span style="font-style: italic;">v</span>)<br>
-</div>
-<br>
-<span style="font-weight: bold;">glRasterPos</span> specifies a
-4-component coordinate (x, y, 0, 1). The coordinate is processed
-like a vertex; it is transformed by the modelview matrix, the projection
-matrix and mapped to the viewport. The resulting window coordinate
-is stored as the current raster position. The coordinate is
-clipped-tested against the frustum like a vertex. If the
-coordinate is clipped, then the current raster position becomes invalid
-and subsequent <span style="font-weight: bold;">glBitmap</span> commands
-have no effect.<br>
-<br>

-<h1>4. Rasterization</h1>
-This section describes the commands and options for drawing points,
-lines, triangles and bitmaps. <span style="font-style: italic;">Rasterization</span>
-is the term for the process which produces fragments from the geometric
-description of a primitive (a point, line, polygon or bitmap). For
-example, given the two coordinates for the end-points of a line segment,
-rasterization determines which pixels in the frame buffer are modified
-to <span style="font-style: italic;">draw</span> the line. A
-fragment is a tuple which consists of a window coordinate, colors and
-texture coordinates. The fragments produced by rasterization are
-subsequently processed by the per-fragment operations described later.<br>
-<br>
-<h2>4.1 Point Rasterization</h2>
-Points are rendered with the command sequence <span
- style="font-weight: bold;">glBegin</span>(GL_POINTS), <span
- style="font-weight: bold;">glVertex</span>, ... <span
- style="font-weight: bold;">glEnd</span>. The window coordinate (x<sub>w</sub>,
-y<sub>w</sub>, z<sub>w</sub>) is truncated to rasterize the point.
- The truncated coordinate with its associated color and texture
-coordinate is sent as a single fragment to the per-fragment processing
-stages.<br>
-<br>
-The <span style="font-weight: bold;">glPointSize</span> command is not
-supported; only 1-pixel points are supported.<br>
-<br>
-Point smoothing (antialiasing) is also not supported.<br>
-<br>
-<h2>4.2 Line Rasterization</h2>
-Lines are rendered with the command sequence <span
- style="font-weight: bold;">glBegin</span>(<span
- style="font-style: italic;">mode</span>), <span
- style="font-weight: bold;">glVertex</span>, <span
- style="font-weight: bold;">glVertex</span>, ... <span
- style="font-weight: bold;">glEnd</span> where <span
- style="font-style: italic;">mode</span> is one of GL_LINES,
-GL_LINE_STRIP or GL_LINE_LOOP. Lines are rasterized as described
-in the OpenGL specification. Note that OpenGL specifies the <span
- style="font-style: italic;">half-open</span> convention for drawing
-lines: the last fragment in a line segment is omitted so that endpoint
-pixels shared by two line segments will only be drawn once instead of
-twice.<br>
-<br>
-<h3>4.2.1 Line Width</h3>
-The width of lines can be controlled by<br>
-<br>
-<div style="margin-left: 40px;">void <span style="font-weight: bold;">glLineWidth</span>(GLfloat<span
- style="font-style: italic;">width</span>)<br>
-</div>
-<br>
-where <span style="font-style: italic;">width</span> is the line width
-in pixels. The width defaults to 1.0. Attempting to set the
-width to a value less than or equal to zero will raise the error
-GL_INVALID_VALUE.<br>
-<br>
-<h3>4.2.2 Line Stipple<br>
-</h3>
-Lines may be stippled (i.e. dashed) with the command<br>
-<br>
-<div style="margin-left: 40px;"><span style="font-weight: bold;">glLineStipple</span>(GLint<span
- style="font-style: italic;">factor</span>, GLushort <span
- style="font-style: italic;">pattern</span>)<br>
-</div>
-<br>
-<span style="font-style: italic;">pattern</span> describes an on/off
-pattern for the fragments produced by rasterization and <span
- style="font-style: italic;">factor</span> specifies how many subsequent
-fragments are kept or culled for each pattern bit. Line stippling
-can be enabled or disabled by the commands <span
- style="font-weight: bold;">glEnable</span>(GL_LINE_STIPPLE) and <span
- style="font-weight: bold;">glDisable</span>(GL_LINE_STIPPLE).<br>
-<br>
-<h3>4.2.3 Line Antialiasing</h3>
-Lines may be antialiased. For antialiased lines, each fragment
-produced by rasterization is assigned a <span
- style="font-style: italic;">coverage value</span> which describes how
-much of the fragment's area is considered to be <span
- style="font-style: italic;">inside</span> the line. Later, the
-alpha value of each fragment is multiplied by the coverage value.
- By blending the fragments into the frame buffer, the edges of
-lines appear smoothed.<br>
-<br>
-Line antialiasing can be enabled or disabled with the commands <span
- style="font-weight: bold;">glEnable</span>(GL_LINE_SMOOTH) and <span
- style="font-weight: bold;">glDisable</span>(GL_LINE_SMOOTH).<br>
-<br>
-<h2>4.3 Polygon Rasterization</h2>
-Polygons, quadrilaterals and triangles share the same polygon
-rasterization options. <br>
-<br>
-Triangles are rendered by the command sequence <span
- style="font-weight: bold;">glBegin</span><span
- style="font-style: italic;"><span style="font-style: italic;">(mode</span></span>),<span
- style="font-weight: bold;">glVertex</span>, <span
- style="font-weight: bold;">glVertex</span>, ... <span
- style="font-weight: bold;">glEnd</span> where <span
- style="font-style: italic;">mode</span> may be one of GL_TRIANGLES,
-GL_TRIANGLE_STRIP or GL_TRIANGLE_FAN.<span style="font-weight: bold;"></span>
- For GL_TRIANGLES mode, the number of vertices should be a multiple
-of three - extra vertices will be ignored. For GL_TRIANGLE_STRIP
-and GL_TRIANGLE_FAN, at least three vertices should be specified.
- If less than three are specified, nothing is drawn. <br>
-<br>
-Quadrilaterals are <span style="font-weight: bold;"></span>rendered by
-the command sequence <span style="font-weight: bold;">glBegin</span>(<span
- style="font-style: italic;"><span style="font-style: italic;">mode</span></span>),<span
- style="font-weight: bold;">glVertex</span>, <span
- style="font-weight: bold;">glVertex</span>, ... <span
- style="font-weight: bold;">glEnd</span> where <span
- style="font-style: italic;">mode</span> may be one of GL_QUADS or
-GL_QUAD_STRIP.<span style="font-weight: bold;"></span> For
-GL_QUADS, the number of vertices should be a multiple of four - extra
-vertices will be ignored. For GL_QUAD_STRIP, the number of
-vertices should be even and at least four. Extra vertices (one)
-will be ignored.<br>
-<br>
-Convex polygons are <span style="font-weight: bold;"></span>rendered
-by the command sequence <span style="font-weight: bold;">glBegin</span><span
- style="font-style: italic;"><span style="font-style: italic;"></span></span>(GL_POLYGON),<span
- style="font-weight: bold;">glVertex</span>, <span
- style="font-weight: bold;">glVertex</span>, ... <span
- style="font-weight: bold;">glEnd</span>.<span
- style="font-style: italic;"></span><span style="font-weight: bold;"></span>
- If less than three vertices are specified, nothing is drawn.<br>
-<br>
-<h3>4.3.1 Polygon Orientation</h3>
-The <span style="font-style: italic;">winding order</span> of vertices
-(clockwise or counter-clockwise) is significant. It is used to
-determine the <span style="font-style: italic;">front-facing</span> or <span
- style="font-style: italic;">back-facing</span> orientation of polygons.
- By default, a front-facing polygon's vertices are in
-counter-clockwise order (in window coordinates). Figures 2.4 and
-2.5 of the OpenGL 1.2.1 specification illustrate the winding order for
-front-facing triangles and quadrilaterals, respectively.<br>
-<br>
-The command<br>
-<br>
-<div style="margin-left: 40px;">void <span style="font-weight: bold;">glFrontFace</span>(GLenum<span
- style="font-style: italic;"> mode</span>)<br>
-</div>
-<br>
-specifies whether clockwise or counter-clockwise winding indicates a
-front-facing polygon. If <span style="font-style: italic;">mode</span>
-is GL_CW then polygons with clockwise winding are front-facing. If <span
- style="font-style: italic;">mode</span> is GL_CCW then polygons with
-counter-clockwise winding are front-facing. The default value is
-GL_CCW. If <span style="font-style: italic;">mode</span> is not
-GL_CCW or GL_CW then the error GL_INVALID_ENUM will be raised.<span
- style="font-style: italic;"></span><span style="font-style: italic;"></span><br>
-<br>
-<h3>4.3.2 Polygon Culling</h3>
-Polygons may be culled (discarded) depending on whether they are
-front-facing or back-facing. The command<br>
-<br>
-<div style="margin-left: 40px;">void<span style="font-weight: bold;">
-glCullFace</span>(GLenum <span style="font-style: italic;">mode</span>)<br>
-</div>
-<br>
-specifies whether front-facing, back-facing or all polygons should be
-culled. If <span style="font-style: italic;">mode</span> is
-GL_FRONT then front-facing polygons will be culled. If <span
- style="font-style: italic;">mode</span> is GL_BACK then back-facing
-polygons will be culled. Otherwise, if <span style="font-style: italic;">mode</span>
-is GL_FRONT_AND_BACK then all polygons will be culled. Any other
-value for <span style="font-style: italic;">mode</span> will raise the
-error GL_INVALID_ENUM.<br>
-<br>
-Polygon culling is enabled and disabled with the commands <span
- style="font-weight: bold;">glEnable</span>(GL_CULL_FACE) and <span
- style="font-weight: bold;">glDisable</span>(GL_CULL_FACE),
-respectively.<br>
-<br>
-<h3>4.3.3 Polygon Antialiasing</h3>
-Polygons may be antialiased in order to smooth their edges.
- Polygon antialiasing is enabled and disabled with the commands <span
- style="font-weight: bold;">glEnable</span>(GL_POLYGON_SMOOTH) and <span
- style="font-weight: bold;">glDisable</span>(GL_POLYGON_SMOOTH).<br>
-<br>
-When polygon antialiasing is enabled each fragment produced by polygon,
-triangle and quadrilateral rasterization will be given a <span
- style="font-style: italic;">coverage</span> value which indicates how
-much of the fragment is covered by the polygon. Fragments
-completely inside the polygon have coverage 1.0. Fragments
-completely outside the polygon have zero coverage (in theory).
- Fragments which intersect the polygon's edge have a coverage value
-in the range (0, 1).<br>
-<br>
-The fragment's alpha value is multiplied by the coverage value.
- By enabling the appropriate blending mode, polygon edges will
-appear smoothed.<br>
-<br>
-<h2>4.4 Shading</h2>
-The command<br>
-<br>
-<div style="margin-left: 40px;"> void <span style="font-weight: bold;">glShadeModel</span>(GLenum<span
- style="font-style: italic;">mode</span>)<br>
-</div>
-<br>
-determines whether colors are interpolated between vertices during
-rasterization. If <span style="font-style: italic;">mode</span> is
-GL_FLAT then vertex colors are not interpolated. The color used
-for drawing lines, triangles and quadrilaterals is that of the last
-vertex used to specify each primitive. For polygons, the color of
-the first vertex specifies the color for the entire polygon. If <span
- style="font-style: italic;">mode</span> is GL_SMOOTH then vertex colors
-are linearly interpolated to produce the fragment colors.<br>
-<br>
-<h2>4.5 Bitmap Rasterization</h2>
-A bitmap is a monochromatic, binary image in which each image element
-(or pixel) is represented by one bit. Fragments are only generated
-for the bits (pixels) which are set. Bitmaps are commonly used to
-draw text (glyphs) and markers.<br>
-<br>
-A bitmap is drawn with the command<br>
-<br>
-<div style="margin-left: 40px;">void <span style="font-weight: bold;">glBitmap</span>(GLsizei<span
- style="font-style: italic;">width</span>, GLsizei <span
- style="font-style: italic;">height</span>, GLfloat <span
- style="font-style: italic;">xOrig</span>, GLfloat <span
- style="font-style: italic;">yOrig</span>, GLfloat <span
- style="font-style: italic;">xMove</span>, GLfloat <span
- style="font-style: italic;">yMove</span>, const GLubyte *<span
- style="font-style: italic;">image</span>)<br>
-</div>
-<br>
-<span style="font-style: italic;">width </span>and <span
- style="font-style: italic;">height</span> specify the image size in
-pixels. <span style="font-style: italic;">xOrig</span> and <span
- style="font-style: italic;">yOrig</span> specify the bitmap origin.
- <span style="font-style: italic;">xMove</span> and <span
- style="font-style: italic;">yMove</span> are added to the current
-raster position after the bitmap is rasterized. <span
- style="font-style: italic;">image</span> is a pointer to the bitmap
-data.<br>
-<br>
-If the current raster position is not valid, <span
- style="font-weight: bold;">glBitmap</span> has no effect.<br>
-<br>
-<h3>4.5.1 Bitmap Unpacking</h3>
-The first step in bitmap rendering is <span style="font-style: italic;">unpacking.
- </span>Unpacking is the process of extracting image data from
-client memory subject to byte swapping, non-default row strides, etc.
- The unpacking parameters are specified with the command<br>
-<br>
-<div style="margin-left: 40px;">void<span style="font-weight: bold;">
-glPixelStorei</span>(GLenum pname, GLint value)<br>
-</div>
-<span style="font-style: italic;"></span><br>
-The following unpacking parameters may be set:<br>

- <td style="vertical-align: top;">GL_FALSE<br>
- </td>
- </tr>
- </tbody>
-</table>
-<br>
-<br>
-The GL_UNPACK_ROW_LENGTH specifies the stride (in pixels) for advancing
-from one row of the image to the next. If it's zero, the <span
- style="font-style: italic;">width</span> parameter to <span
- style="font-weight: bold;">glBitmap</span> specifies the width of the
-image in memory.<br>
-<br>
-GL_UNPACK_LSB_FIRST determines whether the least significant or most
-significant bit in each byte is unpacked first. Unpacking occurs
-in left to right order (in image space).<br>
-<br>
-The value of bit (i, j) of the image (where i is the image row and j is
-the image column) is found as follows:<br>
-<br>
-<div style="margin-left: 40px;">rowLength = (GL_UNPACK_ROW_LENGTH != 0)
-? GL_UNPACK_ROW_LENGTH : <span style="font-style: italic;">width</span>;<br>

-byte = <span style="font-style: italic;">image</span>[((rowLength + 7)
-/ 8) * i + j / 8];<br>
-<br>
-if (GL_UNPACK_LSB_FIRST != 0)<br>
- bitMask = 1 << (j % 8);<br>
-else<br>
- bitMask = 128 >> (j % 8);<br>
-<br>
-if (byte & bitMask)<br>
- bit = 1;<br>
-else<br>
- bit = 0;<br>
-<br>
-</div>
-<span style="font-style: italic;"><span style="font-style: italic;"></span></span>
-<h3>4.5.2 Rasterization</h3>
-If the current raster position is (x<sub>rp</sub>, y<sub>rp</sub>, z<sub>rp</sub>,
-w<sub>rp</sub>), then the bitmap is rasterized according to the
-following algorithm:<br>
-<br>
-for (j = 0; j < <span style="font-style: italic;">height</span>;
-j++) {<br>
- for (i = 0; i < <span style="font-style: italic;">width</span>;
-i++) {<br>
- if (bit(i,j)) {<br>
- fragment.x =

-
-fragment.texture = GL_CURRENT_RASTER_TEXTURE_COORDS;<br>
-
-ProcessFragment(fragment)<br>
- }<br>
- }<br>
-}<br>
-<br>
-After the bitmap has been rendered the current raster position is
-updated as follows:<br>
-<br>
-<div style="margin-left: 40px;">x<sub>rp</sub> = x<sub>rp</sub> + <span
- style="font-style: italic;">xMove</span><br>

-<h1>5. Texture Mapping<br>
-</h1>
-There are four elements to texture mapping: texture coordinate
-specification, texture image specification, texture sampling and texture
-application.<br>
-<br>
-Texture mapping is enabled and disabled with the commands <span
- style="font-weight: bold;">glEnable</span>(GL_TEXTURE_2D) and <span
- style="font-weight: bold;">glDisable</span>(GL_TEXTURE_2D).<br>
-<br>
-<h2>5.1 Texture Image Specification</h2>
-A texture image is specified with the command:<br>
-<br>
-<div style="margin-left: 40px;">void <span style="font-weight: bold;">glTexImage2D</span>(GLenum<span
- style="font-style: italic;"> target</span>, GLint <span

- style="font-style: italic;">pixels</span> )<br>
-</div>
-<br>
-<span style="font-style: italic;">target</span> must be GL_TEXTURE_2D.
- <span style="font-style: italic;">level </span>indicates the
-mipmap level for mipmap textures. <span style="font-style: italic;">internalFormat</span>
-is a hint to indicate the preferred internal storage format for the
-texture. <span style="font-style: italic;">width</span> and <span
- style="font-style: italic;">height </span>indicate the image size in
-pixels (or texels). <span style="font-style: italic;">border </span>must
-be zero. <span style="font-style: italic;">format</span> and <span
- style="font-style: italic;">type</span> describe the pixel format and
-data type for the incoming image. <span style="font-style: italic;">pixels</span>
-points to the incoming texture image. These parameters are
-described in more detail below.<br>
-<br>
-<h3>5.1.1 Texture Image Size and Mipmaps</h3>
-<h3><span style="font-style: italic;"></span></h3>
-Texture images must have dimensions (width and height) that are powers
-of two. For example: 256 x 256, 32 x 1024, 1 x 8, etc. That is, it
-must be the case that <span style="font-style: italic;">width </span>=
-2<sup>n</sup> and <span style="font-style: italic;">height</span> = 2<sup>m</sup>
-for some positive integers n and m.<br>
-<br>
-Mipmapping is a method of antialiasing or filtering textures to improve
-their appearance. A mipmap is a set of images consisting of a base
-image and a set of filtered, reduced-resolution images. If the
-base image (<span style="font-style: italic;">level</span>=0) is of
-width 2<sup>n</sup> and height 2<sup>m</sup> then the level 1 image must
-be of width 2<sup>n-1</sup> and height 2<sup>m-1</sup>. Each mipmap
-level is half the width and height of the previous level, or at least
-one. The last mipmap level has a width and height of one.<br>
-<br>
-The following is an example of a mipmap's image levels:<br>

-If the <span style="font-style: italic;">width</span> or <span

-two, the error GL_INVALID_VALUE is raised. If the image levels in

-considered to be <span style="font-style: italic;">inconsistent</span>
-and the system will behave as if the texturing is disabled.<br>
-<br>
-<h3>5.1.2 Texture Image Formats and Unpacking</h3>
-The <span style="font-weight: bold;">glTexImage2D</span> command's <span
- style="font-style: italic;"><span style="font-weight: bold;"></span></span><span
- style="font-style: italic;">format</span> and <span
- style="font-style: italic;">type</span> parameters describe the format
-of the incoming texture image. Accepted values for <span
- style="font-style: italic;">format</span> are GL_INTENSITY, GL_RGB and
-GL_RGBA. The <span style="font-style: italic;">type</span>
-parameter must be GL_UNSIGNED_BYTE. Pixel component values are
-thus in the range 0 through 255.<br>
-<br>
-If <span style="font-style: italic;">format</span> is GL_INTENSITY then
-the image has one byte per pixel which specifies the pixel's red, green,
-blue and alpha values.<span style="font-style: italic;"></span><br>
-<br>
-If <span style="font-style: italic;">format</span> is GL_RGB then the
-image has three bytes per pixel which specify the pixel's red, green and
-blue values (in that order). The alpha value defaults to 255.<br>
-<br>
-If <span style="font-style: italic;">format</span> is GL_RGBA then the
-image has four bytes per pixel which specify the pixel's red, green,
-blue and alpha values (in that order).<br>
-<br>
-The command<br>
-<br>
-<div style="margin-left: 40px;">void<span style="font-weight: bold;">
-glPixelStorei</span>(GLenum <span style="font-style: italic;">pname</span>,
-GLint <span style="font-style: italic;">value</span>)<br>
-</div>
-<br>
-controls the unpacking of texture image data from client memory. <span
- style="font-style: italic;">pname</span> may be GL_UNPACK_ROW_LENGTH to
-indicate the stride, in pixels, between subsequent rows of the image in
-client memory. If GL_UNPACK_ROW_LENGTH is zero (the default) then
-the <span style="font-style: italic;">width</span> parameter to <span
- style="font-weight: bold;">glTexImage2D </span>determines the stride.<span
- style="font-style: italic;"></span><br>
-<br>
-<h3>5.1.3 Internal Texture Format</h3>
-<span style="font-weight: bold;">glTexImage2D<span
- style="font-style: italic;"> </span></span>converts the incoming
-texture image to one of the supported internal texture formats.<br>
-<br>
-The <span style="font-style: italic;">internalFormat</span> parameter
-indicates the desired internal format for the texture and may be either
-GL_INTENSITY8, GL_RGB5 or GL_RGBA8.<br>
-<br>
-If <span style="font-style: italic;">internalFormat</span> is
-GL_INTENSITY8 then the texture has one byte per texel (texture element)
-which indicates the texel's intensity (or brightness). The
-intensity is obtained from the incoming image's red channel.<br>
-<br>
-If <span style="font-style: italic;">internalFormat</span> is GL_RGB5
-then the texture is stored with two bytes per texel: 5 bits per
-red value, 5 bits per green value and 5 bits per blue value.<br>
-<br>
-If <span style="font-style: italic;">internalFormat </span>is
-GL_RGBA8 then the texture is stored with four bytes per texel: 8
-bits for each of the red, green, blue and alpha values.<br>
-<br>
-The internal format is also significant to texture application (see
-section 5.4).<br>
-<br>
-<h2>5.2 Texture Coordinates</h2>
-Texture coordinates control the mapping from local polygon space to
-texture image space. Texture coordinates are set for each vertex
-with the <span style="font-weight: bold;">glTexCoord</span> commands.
- During line and polygon rasterization the vertex's texture
-coordinates are interpolated across the primitive to produce a texture
-coordinate for each fragment. The fragment texture coordinates are
-used to sample the current texture image.<br>
-<br>
-Texture coordinates are normally in the range [0, 1]. Values
-outside that range are processed according to the <span
- style="font-style: italic;">texture wrap mode</span>. The
-texture wrap mode is set with the command<br>
-<br>
-<div style="margin-left: 40px;">void <span style="font-weight: bold;">glTexParameteri</span>(GLenum<span
- style="font-style: italic;"> target</span>, GLenum <span
- style="font-style: italic;">pname</span>, GLint <span
- style="font-style: italic;">value</span>)<br>
-<br>
-</div>
-<span style="font-style: italic;">target</span> must be GL_TEXTURE_2D.
- If <span style="font-style: italic;">pname</span> is
-GL_TEXTURE_WRAP_S or GL_TEXTURE_WRAP_T then <span
- style="font-style: italic;">value</span> must be either
-GL_CLAMP_TO_EDGE or GL_REPEAT.<br>
-<br>
-For GL_CLAMP_TO_EDGE, texture coordinates are effectively clamped to
-the interval [0, 1].<br>
-<br>
-For GL_REPEAT, the integer part of texture coordinates is ignored; only
-the fractional part of the texture coordinates is used. This
-allows texture images to repeated or tiled across an object.<br>
-<br>
-<h2>5.3 Texture Sampling</h2>
-Texture sampling is the process of using texture coordinates to extract
-a color from the texture image. Multiple, weighted samples may be
-taken from the texture and combined during the filtering step.<br>
-<br>
-During texture coordinate interpolation a <span
- style="font-style: italic;">level of detail</span> value (lambda) is
-computed for each fragment. For a mipmapped texture, lambda
-determines which level (or levels) of the mipmap will be sampled to
-obtain the texture color.<br>
-<br>
-If lambda indicates that multiple texels map to a single screen pixel,
-then the texture <span style="font-style: italic;">minification</span>
-filter will be used. Otherwise, if lambda indicates that a single
-texel maps to multiple screen pixels, then the texture <span
- style="font-style: italic;">magnification</span> filter will be used.<br>
-<span style="font-weight: bold;"></span><span
- style="font-style: italic;"></span><br>
-<h3>5.3.1 Texture Minification</h3>
-The texture minification filter is set with the <span
- style="font-weight: bold;">glTexParameteri </span><span
- style="font-style: italic;"></span><span style="font-weight: bold;"></span><span
- style="font-style: italic;"></span> command by setting <span
- style="font-style: italic;">target</span> to GL_TEXTURE_2D, setting <span
- style="font-style: italic;">pname</span> to GL_TEXTURE_MIN_FILTER and
-setting <span style="font-style: italic;">value</span> to GL_NEAREST,
-GL_LINEAR, GL_NEAREST_MIPMAP_NEAREST,
-GL_NEAREST_MIPMAP_LINEAR, GL_LINEAR_MIPMAP_NEAREST or
-GL_LINEAR_MIPMAP_LINEAR.<br>
-<br>
-GL_NEAREST samples the texel nearest the texture coordinate in the
-level 0 texture image.<br>
-<br>
-GL_LINEAR samples the four texels around the texture coordinate in the
-level 0 texture image. The four texels are linearly weighted to
-compute the final texel value.<br>
-<br>
-GL_NEAREST_MIPMAP_NEAREST samples the texel nearest the texture
-coordinate in the level N texture image. N is the level of detail
-and is computed by the partial derivatives of the texture coordinates
-with respect to the window coordinates.<br>
-<br>
-GL_NEAREST_MIPMAP_LINEAR samples two texels nearest the texture
-coordinates in the level N and N+1 texture images. The two texels
-are linearly weighted to compute the final texel value. N is the
-level of detail and is computed by the partial derivatives of the
-texture coordinates with respect to the window coordinates.<br>
-<br>
-GL_LINEAR_MIPMAP_NEAREST samples four texels around the texture
-coordinate in the level N texture image. The four texels are
-linearly weighted to compute the final texel value. N is the level
-of detail and is computed by the partial derivatives of the texture
-coordinates with respect to the window coordinates.<br>
-<br>
-GL_LINEAR_MIPMAP_LINEAR samples four texels around the texture
-coordinate in the level N texture image and four texels around the
-texture coordinate in the level N+1 texture image. The eight
-texels are linearly weighted to compute the final texel value. N
-is the level of detail and is computed by the partial derivatives of the
-texture coordinates with respect to the window coordinates.<br>
-<br>
-Filter modes other than GL_LINEAR and GL_NEAREST requires that the
-texture have a complete set of mipmaps. If the mipmap is
-incomplete, it is as if texturing is disabled.<br>
- <br>
-<h3>5.3.2 Texture Magnification</h3>
-The texture magnification filter is set with the <span
- style="font-weight: bold;">glTexParameteri </span><span
- style="font-style: italic;"></span><span style="font-weight: bold;"></span>command
-by setting <span style="font-style: italic;">target</span> to
-GL_TEXTURE_2D, setting <span style="font-style: italic;">pname</span> to
-GL_TEXTURE_MAG_FILTER and setting <span style="font-style: italic;">value</span>
-to GL_NEAREST or GL_LINEAR.<br>
-<br>
-GL_NEAREST samples the texel nearest the texture coordinate in the
-level 0 texture image.<br>
-<br>
-GL_LINEAR samples the four texels around the texture coordinate in the
-level 0 texture image. The four texels are linearly weighted to
-compute the final texel value.<br>
-<br>
-<h2>5.4 Texture Application</h2>
-The sampled texture value is combined with the incoming fragment color
-to produce a new fragment color. The fragment and texture colors
-are combined according to the texture environment mode and the current
-texture's base internal format. The texture environment mode is
-set with the command<br>
-<br>
-<div style="margin-left: 40px;">void<span style="font-weight: bold;">
-glTexEnvi</span>(GLenum <span style="font-style: italic;">target</span>,
-GLenum <span style="font-style: italic;">pname</span>, GLint <span
- style="font-style: italic;">value</span>)<br>
-</div>
-<br>
-<span style="font-style: italic;">target</span> must be GL_TEXTURE_ENV.
- If <span style="font-style: italic;">pname</span> is
-GL_TEXTURE_ENV_MODE then <span style="font-style: italic;">value</span>
-must be one of GL_REPLACE, GL_MODULATE, GL_DECAL, or GL_BLEND.<br>
-<br>
-There is also a <span style="font-style: italic;">texture environment
-color</span> that can factor into texture application. The texture
-environment color can be set with the command<br>
-<br>
-<div style="margin-left: 40px;">void<span style="font-weight: bold;">
-glTexEnvfv</span>(GLenum <span style="font-style: italic;">target</span>,
-GLenum <span style="font-style: italic;">pname</span>, const GLfloat *<span
- style="font-style: italic;">value</span>)<br>
-</div>
-<span style="font-style: italic;"></span><br>
-<span style="font-style: italic;">target</span> must be GL_TEXTURE_ENV.
- If <span style="font-style: italic;">pname</span> is
-GL_TEXTURE_ENV_COLOR then <span style="font-style: italic;">value </span>must
-point to an array of four values which specify the red, green, blue,
-and alpha values of the texture environment color. The values are
-clamped to the range [0, 1]. The default color is (0, 0, 0, 0).<br>
-<span style="font-style: italic;"></span><br>
-The following table describes the arithmetic used for each combination
-of environment mode and base internal format. (Rf, Gf, Bf, Af) is
-the incoming fragment color. (Rt, Gt, Bt, At) is the sampled
-texture color. Lt is the sampled texture luminance. <span
- style="font-style: italic;"></span>'It' is the sampled texture
-intensity. (Rc, Gc, Bc, Ac) is the texture environment color.
- (Rv, Gv, Bv, Av) is the resulting value.<br>

-<h2>5.5 Texture Objects</h2>
-Texture objects encapsulate a set of texture images (mipmap) and
-related state into a named object. This facilitates use of
-multiple textures in an application. Texture objects are named
-with GLuints (unsigned integers). There is a default texture
-object with the name/identifier zero which can never be deleted.<br>
-<br>
-<h3>5.5.1 Creating Texture Objects</h3>
-A texture object is created by binding a new GLuint identifier to the
-GL_TEXTURE_2D target with the command:<br>
-<br>
-<div style="margin-left: 40px;">void <span style="font-weight: bold;">glBindTexture</span>(GLenum<span
- style="font-style: italic;"> target</span>, GLuint <span
- style="font-style: italic;">textureID</span>)<br>
-</div>
-<br>
-<span style="font-style: italic;">target</span> must be GL_TEXTURE_2D.
- <span style="font-style: italic;">textureID</span> may be any
-unsigned integer. If <span style="font-style: italic;">textureID</span>
-does not name an existing texture object, a new texture object with that
-ID will be created, initialized to the default state. Whether the
-ID is new or existed previously, that named texture object is bound as
-the <span style="font-style: italic;">current texture object</span>.
- Subsequent <span style="font-weight: bold;">glTexParameter </span>and<span
- style="font-weight: bold;">glTexImage2D<span
- style="font-style: italic;"> </span></span>calls will effect the
-current texture object.<br>
-<span style="font-style: italic;"></span><span
- style="font-weight: bold;"><span style="font-style: italic;"> </span></span><br>
-<h3>5.5.2 Deleting Texture Objects</h3>
-One or more texture objects may be deleted with the command:<br>
-<br>
-<div style="margin-left: 40px;">void <span style="font-weight: bold;">glDeleteTextures</span>(GLsizei<span
- style="font-style: italic;">n</span>, const GLuint *<span
- style="font-style: italic;">textureIDs</span>)<br>
-</div>
-<br>
-<span style="font-style: italic;">textureIDs</span> is an array of <span
- style="font-style: italic;">n</span> texture IDs. The named
-texture objects will be deleted. If the current texture object is
-deleted the default texture object (number 0) will be bound as the
-current texture object.<br>
-<br>
-<h3>5.5.3 Allocating Texture Object Identifiers</h3>
-A list of new, unused texture IDs can be obtained by calling the command<br>
-<br>
-<div style="margin-left: 40px;">void <span style="font-weight: bold;">glGenTextures</span>(GLsizei<span
- style="font-style: italic;"> n</span>, GLuint *<span
- style="font-style: italic;">textureIDs</span>)<br>
-</div>
-<br>
-An array of <span style="font-style: italic;">n</span> unused texture
-IDs will be returned in the <span style="font-style: italic;">textureIDs</span>
-array.<br>
-<br>
-<br>
-<h1>6. Per-fragment Operations</h1>
-The fragments produced by rasterization are subjected to a number of
-operations which either modify the fragment or test the fragment
-(discarding the fragment if the test fails.) This chapter
-describes the per-fragment operations. They are presented in the
-order in which they're performed. If a fragment fails a test it is
-discarded and not subjected to subsequent tests or modifications.<br>
-<br>
-<h2>6.1 Scissor Test</h2>
-The scissor test limits rendering to a 2-D rectangular region of the
-framebuffer. The command<br>
-<br>
-<div style="margin-left: 40px;">void <span style="font-weight: bold;">glScissor</span>(GLint<span
- style="font-style: italic;">x</span>, GLint <span
- style="font-style: italic;">y</span>, GLsizei <span
- style="font-style: italic;">width</span>, GLsizei<span
- style="font-style: italic;"> height</span>)<br>
-</div>
-<br>
-defines a clipping region with the lower-left corner at (<span
- style="font-style: italic;">x, y</span>) and the given <span
- style="font-style: italic;">width</span> and <span
- style="font-style: italic;">height</span>. The scissor test is
-enabled and disabled with the command <span style="font-weight: bold;">glEnable</span>(GL_SCISSOR_TEST)
-and <span style="font-weight: bold;">glDisable</span>(GL_SCISSOR_TEST).<br>
-<br>
-If the incoming fragment's position is (x<sub>f</sub>, y<sub>f</sub>)
-then the fragment will pass the test if <span
- style="font-style: italic;">x</span> <= x<sub>f</sub> < <span
- style="font-style: italic;">x</span> + <span
- style="font-style: italic;">width</span> and <span
- style="font-style: italic;">y</span> <= y<sub>f</sub> < <span
- style="font-style: italic;">y</span> + <span
- style="font-style: italic;">height. </span>Otherwise, the
-fragment is discarded.<br>
-<br>
-If <span style="font-style: italic;">width</span> or <span
- style="font-style: italic;">height</span> is less than zero the error
-GL_INVALID_VALUE is raised. The default scissor rectangle bounds
-are (0, 0, w, h) where w is the initial window width and h is the
-initial window height. The scissor test is disabled by default.<br>
-<br>
-<h2>6.2 Alpha Test</h2>
-The alpha test compares the fragment's alpha value against a reference
-value and discards the fragment if the comparison fails. The test
-is specified by the command<br>
-<br>
-<div style="margin-left: 40px;">void <span style="font-weight: bold;">glAlphaFunc</span>(GLenum<span
- style="font-style: italic;">mode</span>, GLclampf <span

-The default mode is GL_ALWAYS and the default reference value is 0.<br>
-<br>
-<h2>6.3 Stencil Test</h2>
-The stencil buffer stores an N-bit integer value for each pixel in the
-frame buffer. The stencil test compares the stencil buffer value
-at the fragment's position to a reference value and possibly discards
-the fragment based on the outcome. Furthermore, the stencil buffer
-value may be updated or modified depending on the outcome. If
-there is no stencil buffer the stencil test is bypassed.<br>

-<h1>7. Frame Buffer Operations</h1>
-The frame buffer is considered to be a two-dimensional array of pixels.
- The frame buffer is also organized into layers or logical buffers.
- There may be a front color buffer, back color buffer and stencil
-buffer. A double-buffered frame buffer has both a front color
-buffer and back color buffer. A single-buffered framebuffer only
-has a front color buffer. Each pixel in a color buffer has a red,
-green and blue value and an optional alpha value.<br>
-<br>
-<h2>7.1 Clearing Buffers</h2>
-Buffers are cleared (set to uniform values) with the command<br>
-<br>
-<div style="margin-left: 40px;">void <span style="font-weight: bold;">glClear</span>(GLbitfield<span
- style="font-style: italic;">buffers</span>)<br>
-</div>
-<br>
-<span style="font-style: italic;">buffers</span> is a bitmask for which
-the value may be the bitwise-OR of the values GL_COLOR_BUFFER_BIT and
-GL_STENCIL_BUFFER_BIT. If the GL_COLOR_BUFFER_BIT bit is
-specified, the current color buffer will be cleared. If the
-GL_STENCIL_BUFFER_BIT bit is specified, the stencil buffer will be
-cleared.<br>
-<br>
-The current color buffer is specified with the command<br>
-<br>
-<div style="margin-left: 40px;">void <span style="font-weight: bold;">glDrawBuffer</span>(GLenum<span
- style="font-style: italic;"> buffer</span>)<br>
-</div>
-<br>
-<span style="font-style: italic;">buffer</span> may be either GL_FRONT,
-GL_BACK or GL_NONE. GL_FRONT indicates that the front color buffer
-will be modified by <span style="font-weight: bold;">glClear</span> and
-any drawing command. GL_BACK indicates that the back color buffer
-will be modified by <span style="font-weight: bold;">glClear</span> and
-any drawing command. GL_NONE indicates that neither color buffer
-will be modified by <span style="font-weight: bold;">glClear</span> or
-any drawing command. GL_BACK is only valid for double-buffered
-frame buffers.<br>
-<br>
-The current scissor rectangle, set by the <span
- style="font-weight: bold;">glScissor</span> command, effects <span
- style="font-weight: bold;">glClear</span><span
- style="font-style: italic;">,</span><span style="font-style: italic;"> </span>limiting
-the clear to the scissor rectangle, if it's enabled. Furthermore, <span
- style="font-weight: bold;"></span>only the color channels enabled by <span
- style="font-weight: bold;">glColorMask</span> will be effected by <span
- style="font-weight: bold;">glClear</span>(GL_COLOR_BUFFER_BIT).
- Likewise, only the stencil bits enabled by <span
- style="font-weight: bold;">glStencilMask</span> will be effected by <span
- style="font-weight: bold;">glClear</span>(GL_STENCIL_BUFFER_BIT).<br>
-<br>
-The current clear color is set with the command<br>
-<br>
-<div style="margin-left: 40px;">void <span style="font-weight: bold;">glClearColor</span>(GLclampf<span
- style="font-style: italic;">red</span>, GLclampf <span

- style="font-style: italic;">alpha</span>)<br>
-</div>
-<br>
-Subsequent calls to <span style="font-weight: bold;">glClear</span>
-will use the color (<span style="font-style: italic;">red, green, blue,
-alpha</span>) to clear the front or back color buffers.<br>
-<span style="font-style: italic;"></span><br>
-The current stencil clear value is set with the command<br>
-<br>
-<div style="margin-left: 40px;">void <span style="font-weight: bold;">glClearStencil</span>(GLint<span
- style="font-style: italic;">clearValue</span>)<br>
-</div>
-<br>
-If the stencil buffer is N bits deep, the least significant N bits of <span

-<h1>8. Other Features</h1>
-<h2>8.1 Frame Buffer Readback</h2>
-A rectangular region of pixels can be read from the frame buffer and
-placed in client memory with the command<br>
-<br>
-<div style="margin-left: 40px;">void <span style="font-weight: bold;">glReadPixels</span>(GLint<span

- style="font-style: italic;">type</span>, GLvoid *<span
- style="font-style: italic;">data</span>)<br>
-</div>
-<br>
-<span style="font-style: italic;">x</span> and <span
- style="font-style: italic;">y</span> specify the coordinate of the
-lower-left corner of the region to read and <span
- style="font-style: italic;">width</span> and <span
- style="font-style: italic;">height</span> specify the size of the
-rectangular region to read. <span style="font-style: italic;">format</span>
-specifies the format of image data and must be either GL_RGB or
-GL_RGBA. <span style="font-style: italic;">type</span> specify the
-data type of the image data and must be either GL_UNSIGNED_BYTE or
-GL_FLOAT. Other values for <span style="font-style: italic;">format</span>
-or <span style="font-style: italic;">type</span> will cause the error
-GL_INVALID_ENUM to be raised.<br>
-<br>
-The framebuffer may contain 3-component colors (red, green, blue) or
-4-component colors (red, green, blue, alpha). If an alpha channel
-is not present, alpha values default to 1.0.<br>
-<br>
-The frame buffer color components (red, green, blue, alpha) are either
-converted to 8-bit unsigned integers in the range[0, 255] if <span
- style="font-style: italic;">type </span>is GL_UNSIGNED_BYTE or
-converted to floating point values in the range [0, 1] if <span
- style="font-style: italic;">type</span> is GL_FLOAT. The (red,
-green, blue, alpha) tuples are then stored as GL_RGB triplets (by
-dropping the alpha component) or GL_RGBA quadruples in client memory.<br>
-<br>
-Image data is <span style="font-style: italic;">packed</span> into
-client memory according to the pixel packing parameters which are set by
-the command<br>

-</div>
-<br>
-The function FrameBuffer(<span style="font-style: italic;">c, r</span>)
-returns the pixel in the frame buffer at column <span
- style="font-style: italic;">c</span> of row <span
- style="font-style: italic;">r. </span><span
- style="font-style: italic;">data</span> is considered to be either a
-GLubyte pointer or a GLfloat pointer, depending on the <span
- style="font-style: italic;">type</span> parameter. Similarly, the
-FrameBuffer function returns either GLubyte values in the range [0, 255]
-or GLfloat values in the range [0,1], depending on the <span
- style="font-style: italic;">type</span> parameter.<br>
-<br>
-Pixels may be read from either the front or back color buffer.
- The command<br>
-<br>
-<div style="margin-left: 40px;">void <span style="font-weight: bold;">glReadBuffer</span>(GLenum<span
- style="font-style: italic;">buffer</span>)<br>
-</div>
-<br>
-specifies the source for reading images with <span
- style="font-weight: bold;">glReadPixels</span>. If <span
- style="font-style: italic;">buffer</span> is GL_FRONT then front color
-buffer is the source. If <span style="font-style: italic;">buffer</span>
-is GL_BACK then the back color buffer is the source. It is illegal
-to specify GL_BACK when the color buffer is not double buffered.
- Any invalid value for <span style="font-style: italic;">buffer</span>
-will raise the error GL_INVALID_ENUM.<br>
-<br>
-The default read source is GL_BACK if the frame buffer is double
-buffered. Otherwise, the default read source is GL_FRONT.<br>
-<br>
-<h2>8.2 Selection Mode</h2>
-Selection mode is typically used to implement <span
- style="font-style: italic;">picking</span>: determining which
-primitive(s) are present at particular window positions. The
-command<br>
-<br>
-<div style="margin-left: 40px;">GLint <span style="font-weight: bold;">glRenderMode</span>(GLenum<span
- style="font-style: italic;">mode</span>)<br>
-</div>
-<br>
-is used to enable selection mode. If <span
- style="font-style: italic;">mode</span> is GL_SELECTION the graphics
-library is put into selection mode. If <span
- style="font-style: italic;">mode</span> is GL_RENDER the graphic
-library is put into normal rendering mode. Any other value for <span
- style="font-style: italic;">mode</span> will raise the error
-GL_INVALID_ENUM.<br>
-<br>
-When in selection mode rendering commands will not effect the
-framebuffer. Instead, a record of the primitives that would have
-been drawn is placed in the <span style="font-style: italic;">selection</span> <span
- style="font-style: italic;">buffer</span>. The selection buffer
-is specified with the command<br>
-<br>
-<div style="margin-left: 40px;">void <span style="font-weight: bold;">glSelectionBuffer</span>(GLsizei<span
- style="font-style: italic;">n</span>, GLuint *<span
- style="font-style: italic;">buffer</span>)<br>
-</div>
-<span style="font-style: italic;"></span><span
- style="font-style: italic;"><br>
-buffer</span> is an array of <span style="font-style: italic;">n</span>
-unsigned integers. No more than <span style="font-style: italic;">n</span>
-values will be placed in the buffer.<br>
-<br>
-The <span style="font-style: italic;">name stack</span> is a stack
-(LIFO) of unsigned integer names. The following commands
-manipulate the name stack:<br>
-<br>
-<div style="margin-left: 40px;">void <span style="font-weight: bold;">glInitNames</span>(void)<br>
-void <span style="font-weight: bold;">glPushName</span>(GLuint <span
- style="font-style: italic;">name</span>)<br>
-void <span style="font-weight: bold;">glPopName</span>(void)<br>
-void <span style="font-weight: bold;">glLoadName</span>(GLuint <span
- style="font-style: italic;">name</span>)<br>
-</div>
-<br>
-<span style="font-weight: bold;">glInitNames</span> resets the name
-stack to an empty state. <span style="font-weight: bold;">glPushName<span
- style="font-style: italic;"> </span></span>pushes the given <span
- style="font-style: italic;">name</span> value onto the stack. <span
- style="font-weight: bold;">glPopName</span> pops the top name from the
-stack. <span style="font-weight: bold;">glLoadName<span
- style="font-style: italic;"> </span></span>replaces the top value on
-the stack with the specified <span style="font-style: italic;">name</span>.
- Stack underflow and overflow conditions cause the errors
-GL_STACK_OVERFLOW and GL_STACK_UNDERFLOW to be raised.<br>
-<br>
-While in selection mode, primitives (points, lines, polygons) are
-transformed and clip-tested normally. Primitives which aren't
-discarded by clipping cause the <span style="font-style: italic;">hit</span> <span
- style="font-style: italic;">data</span> to be updated. The hit
-data consists of three pieces of information: a hit flag, a minimum Z
-value and a maximum Z value. First, the hit flag is set.
- Then, for each of the primitive's vertices, the vertex Z value is
-compared to the minimum and maximum Z values. The minimum Z value
-is updated if the vertex's Z value is less than the minimum Z value.
- The maximum Z value is updated if the vertex's Z value is greater
-than the maximum Z value.<br>
-<br>
-When any of <span style="font-weight: bold;">glInitNames</span><span
- style="font-style: italic;"><span style="font-style: italic;">, </span></span><span
- style="font-weight: bold;">glPushName</span>, <span
- style="font-weight: bold;">glPopName</span>, <span
- style="font-weight: bold;">glLoadName</span> or <span
- style="font-weight: bold;">glRenderMode</span> are called and the hit
-flag is set, a <span style="font-style: italic;">hit record</span> is
-written to the selection buffer.<br>
-<br>
-A hit record consists of a sequence of unsigned integers. The
-first value is the size of the name stack. The second value is the
-minimum Z value multiplied by 2<sup>32</sup>-1. The third value is
-the maximum Z value multiplied by 2<sup>32</sup>-1. The remaining
-values are the values in the name stack, in bottom to top order.
- The hit flag is cleared after a hit record is written to the
-selection buffer. Hit records are places sequentially into the
-selection buffer until it is full or selection mode is terminated.<br>
-<br>
-Selection mode is terminated by calling <span
- style="font-weight: bold;">glRenderMode</span>(GL_RENDER). The
-return value of <span style="font-weight: bold;">glRenderMode</span>
-will be -1 if the selection buffer overflowed. Otherwise, the
-return value will indicate the number of values written into the
-selection buffer.<br>
-<br>
-<h2>8.3 Synchronization</h2>
-The command<br>
-<br>
-<div style="margin-left: 40px;">void <span style="font-weight: bold;">glFlush</span>(void)<br>
-</div>
-<br>
-makes the graphics library to flush all pending graphics commands.
- The command<br>
-<div style="margin-left: 40px;"><br>
-void <span style="font-weight: bold;">glFinish</span>(void)<br>
-</div>
-<br>
-makes the graphics library flush the command queue and wait until those
-commands are completed. <span style="font-weight: bold;">glFlush</span>
-will not return until all previous graphics commands have been fully
-completed.<br>
-<br>
-These commands are typically used to force completion of rendering to
-the front color buffer. Otherwise, rendering to the front color
-buffer may not appear. The <span style="font-style: italic;">swapbuffers</span>
-command (part of the window system binding library) does an implicit
-flush before swapping the front and back color buffers. The <span
- style="font-weight: bold;">glReadPixels</span> command also does an
-implicit flush before reading pixel data from the frame buffer.<br>
-<br>
-<h1>9. State Queries</h1>
-The current value of nearly all library state variables can be queried.
- This chapter describes the commands used for querying the value of
-state variables.<br>
-<br>
-<h2>9.1 General State Queries</h2>
-The command<br>
-<br>
-<div style="margin-left: 40px;">void <span style="font-weight: bold;">glGetFloatv</span>(GLenum<span
- style="font-style: italic;">pname</span>, GLfloat *<span
- style="font-style: italic;">values</span>)<br>
-</div>
-<br>
-returns the value(s) of the state variable specified by <span
- style="font-style: italic;">pname</span>. The following table
-lists all accepted values for <span style="font-style: italic;">pname</span>
-and a description of the value(s). Specifying any other value for <span
- style="font-style: italic;">pname</span> causes the error
-GL_INVALID_ENUM to be raised.<br>

-<br>
-<br>
-<h1>Appendix A: Issues</h1>
-This appendix lists documentation and subset issues with their current
-status. For items which are still open, the documentation (above)
-follows the recommended solution.<br>
-<br>
-<h2>A.1 Vertex Arrays</h2>
-Should vertex arrays be supported? Is there a performance
-advantage?<br>
-<br>
-RESOLUTION: No, there isn't enough of a performance advantage to
-justify them.<br>
-<br>
-<h2>A.2 Polygon Antialiasing and Edge Flags</h2>
-Should edge flags be supported for antialiasing?<br>
-<br>
-Edge flags don't effect antialiasing, at least not normally. A
-number of approaches to antialiasing have been summarized in email.<br>
-<br>
-RECOMMENDATION: don't support edge flags. They don't effect
-polygon antialiasing.<br>
-<br>
-RESOLUTION: closed, as of 26 Feb 2003.<br>
-<br>
-<h2>A.3 glRasterPos vs. glWindowPos</h2>
-Should glRasterPos and/or glWindowPos commands be supported?<br>
-<br>
-RESOLUTION: Closed: implement glRasterPos commands, but not glWindowPos
-commands.<br>
-<br>
-<h2>A.4 GL_IBM_rasterpos_clip extension</h2>
-Should the GL_IBM_rasterpos_clip extension be implemented?<br>
-<br>
-RESOLUTION: No. It's not required.<br>
-<br>
-<h2>A.5 Image Formats and Types</h2>
-Which image formats and types should be supported for <span
- style="font-weight: bold;">glTexImage2D</span> and <span
- style="font-weight: bold;">glReadPixels</span>?<br>
-<br>
-OpenGL specifies a <span style="font-weight: bold;">large</span>
-variety of image formats and data types. Only a few are commonly
-used.<br>
-<br>
-RECOMMENDATION: we propose a subset:<br>
-<br>
-For <span style="font-weight: bold;">glTexImage2D</span> only allow <span
- style="font-style: italic;">type</span>=GL_UNSIGNED_BYTE and <span
- style="font-style: italic;">format</span>=GL_RGBA, GL_RGB,
-GL_INTENSITY. Only allow <span style="font-style: italic;">internalFormat</span>
-to be GL_RGBA, GL_RGB or GL_INTENSITY as well. Basically, only
-support image formats/types that are directly supported by the Radeon
-hardware. This will allow <span style="font-weight: bold;">glTexImage2D</span>
-to basically just use <span style="font-weight: bold;">memcpy</span> to
-copy texture images.<br>
-<br>
-For <span style="font-weight: bold;">glReadPixels</span>, only allow <span
- style="font-style: italic;">type</span> = GL_UNSIGNED_BYTE or GL_FLOAT.
- Only allow <span style="font-style: italic;">format</span> =
-GL_RGB or GL_RGBA. This is just enough to support the OpenGL
-conformance tests.<br>
-<br>
-RESOLUTION: open<br>
-<br>
-<h2>A.6 Texture Environment Modes</h2>
-Which texture environment modes should be supported? OpenGL 1.2
-has GL_REPLACE, GL_MODULATE, GL_DECAL and GL_BLEND. GL_DECAL isn't
-defined for all base internal texture formats. GL_ADD is another
-useful mode. Perhaps drop GL_DECAL mode and add GL_ADD mode.<br>
-<br>
-RECOMMENDATION: implement the standard modes GL_REPLACE, GL_MODULATE,
-GL_DECAL and GL_BLEND.<br>
-<br>
-RESOLUTION: open<br>
-<br>
-<h2>A.7 Truncated Mipmaps and LOD Control</h2>
-Should we support the GL_TEXTURE_BASE_LEVEL, GL_TEXTURE_MAX_LEVEL,
-GL_TEXTURE_MIN_LOD and GL_TEXTURE_MAX_LOD texture parameters?<br>
-<br>
-RECOMMENDATION: We propose omitting these features at this time,
-in the interest of simplifying the driver.<br>
-<br>
-RESOLUTION: open<br>
-<br>
-<h2>A.8 Texture Priorities and Residency</h2>
-Should the subset support texture priorities via <span
- style="font-weight: bold;">glPrioritizeTextures</span> and the <span
- style="font-weight: bold;">glAreTexturesResident</span> command?<br>
-<br>
-RECOMMENDATION: Few applications use these features and
-functions. We propose omitting them to simplify the driver.<br>
-<br>
-RESOLUTION: open<br>
-<br>
-<h2>A.9 Pixel Pack/Unpack Alignment Control</h2>
-Should we support the GL_PACK_ALIGNMENT and GL_UNPACK_ALIGNMENT options?<br>
-<br>
-These are used to align pixel data addresses to 1, 2 and 4-byte
-multiples for <span style="font-weight: bold;">glBitmap, glTexImage2D</span>
-and <span style="font-weight: bold;">glReadPixels</span>. These
-aren't strictly needed since the user can provide a 1, 2 or 4-byte
-aligned address and appropriate GL_PACK_ROW_LENGTH or
-GL_UNPACK_ROW_LENGTH values instead.<br>
-<br>
-RECOMMENDATION: We recommend omitting them to simplify the driver.<br>
-<br>
-RESOLUTION: open<br>
-<br>
-<h2>A.10 Pixel Pack/Unpack Skip Rows/Pixels Control</h2>
-Should we support the GL_UNPACK_SKIP_PIXELS, GL_UNPACK_SKIP_ROWS,
-GL_PACK_SKIP_PIXELS and GL_PACK_SKIP_ROWS options for pixel
-unpacking/packing?<br>
-<br>
-These options aren't really needed since the user can adjust the start
-address and GL_PACK/UNPACK_ROW_LENGTH parameters to achieve the same
-effect.<br>
-<br>
-RECOMMENDATION: omit these parameters.<br>
-<br>
-RESOLUTION: open<br>
-<br>
-<h2>A.11 Texture State Queries</h2>
-Should we support the command <span style="font-weight: bold;">glGetTexEnvi/fv,
-glGetTexParameteri/fv</span> and <span style="font-weight: bold;">glGetTexLevelParameteri/fv</span>?<br>
-<br>
-RECOMMENDATION: No. They're seldom needed and their
-implementation is several hundred lines of code in length.<br>
-<br>
-RESOLUTION: open<br>
-<br>
-<h2>A.12 glGetIntegerv, glGetBooleanv and glGetDoublev</h2>
-Should we support the commands <span style="font-weight: bold;">glGetIntegerv,
-glGetBooleanv </span>and <span style="font-weight: bold;">glGetDoublev</span>
-in addition to <span style="font-weight: bold;">glGetFloatv</span>?<br>
-<br>
-RECOMMENDATION: Omit the boolean, integer and double-valued
-functions. All state values which can be queried by these commands can
-be expressed as floating point values and queried with <span
- style="font-weight: bold;">glGetFloatv</span>. The
-implementation of the other three commands involves many lines of code.<br>
-<br>
-RESOLUTION: open<br>
-<br>
-<h2>A.13 glBitmap and Per-Fragment Operations</h2>
-Should bitmaps rendered with <span style="font-weight: bold;">glBitmap</span>
-be subjected to the per-fragment operations?<br>
-<br>
-If bitmaps are implemented with points it will be easy to implement the
-per-fragment operations. Otherwise, it could be difficult.<br>
-<br>
-RECOMMENDATION: Implement glBitmap by drawing points/pixels with
-the hardware. This will make supporting the per-fragments
-trivially easy. Also, it makes portrait-mode display relatively
-easy.<br>
-<br>
-RESOLUTION: open<br>
-<br>
-<h2>A.14 Reduced gl.h Header File</h2>
-Should we produce a reduced gl.h header file which only defines the
-tokens and functions which are implemented by the subset?<br>
-<br>
-RECOMMENDATION: yes. It would be a useful reference to
-programmers to quickly determine which functions and tokens are
-supported.<br>
-<br>
-RESOLUTION: open<br>
-<br>
-<h2>A.15 glPolygonMode</h2>
-Is <span style="font-weight: bold;">glPolygonMode</span> needed?<br>
-<br>
-RECOMMENDATION: No. Omit it.<br>
-<br>
-RESOLUTION: closed, as of 26 Feb 2003<br>

-<BODY>
-
-<H1>Xlib Software Driver</H1>
-
-<p>
-Mesa's Xlib driver provides an emulation of the GLX interface so that
-OpenGL programs which use the GLX API can render to any X display, even
-those that don't support the GLX extension.
-Effectively, the Xlib driver converts all OpenGL rendering into Xlib calls.
-</p>
-
-<p>
-The Xlib driver is the oldest Mesa driver and the most mature of Mesa's
-software-only drivers.
-</p>
-
-<p>
-Since the Xlib driver <em>emulates</em> the GLX extension, it's not
-totally conformant with a true GLX implementation.
-The differences are fairly obscure, however.
-</p>
-
-<p>
-The unique features of the Xlib driver follows.
-</p>
-
-
-<H2>X Visual Selection</H2>
-<p>
-Mesa supports RGB(A) rendering into almost any X visual type and depth.
-</p>
-<p>
-The glXChooseVisual function tries to choose the best X visual
-for the given attribute list. However, if this doesn't suit your needs
-you can force Mesa to use any X visual you want (any supported by your
-X server that is) by setting the <b>MESA_RGB_VISUAL</b> and
-<b>MESA_CI_VISUAL</b>
-environment variables.
-When an RGB visual is requested, glXChooseVisual
-will first look if the MESA_RGB_VISUAL variable is defined.
-If so, it will try to use the specified visual.
-Similarly, when a color index visual is requested, glXChooseVisual will
-look for the MESA_CI_VISUAL variable.
-</p>
-
-<p>
-The format of accepted values is: <code>visual-class depth</code>
-</p>
-<p>
-Here are some examples:
-</p>
-<pre>
- using csh:
- % setenv MESA_RGB_VISUAL "TrueColor 8" // 8-bit TrueColor
- % setenv MESA_CI_VISUAL "PseudoColor 12" // 12-bit PseudoColor
- % setenv MESA_RGB_VISUAL "PseudoColor 8" // 8-bit PseudoColor
-
- using bash:
- $ export MESA_RGB_VISUAL="TrueColor 8"
- $ export MESA_CI_VISUAL="PseudoColor 12"
- $ export MESA_RGB_VISUAL="PseudoColor 8"
-</pre>
-
-
-<H2>Double Buffering</H2>
-<p>
-Mesa can use either an X Pixmap or XImage as the back color buffer when in
-double-buffer mode.
-The default is to use an XImage.
-The <b>MESA_BACK_BUFFER</b> environment variable can override this.
-The valid values for <b>MESA_BACK_BUFFER</b> are: <b>Pixmap</b> and
-<b>XImage</b> (only the first letter is checked, case doesn't matter).
-</p>
-
-<p>
-Using XImage is almost always faster than a Pixmap since it resides in
-the application's address space.
-When glXSwapBuffers() is called, XPutImage() or XShmPutImage() is used
-to transfer the XImage to the on-screen window.
-</p>
-<p>
-A Pixmap may be faster when doing remote rendering of a simple scene.
-Some OpenGL features will be very slow with a Pixmap (for example, blending
-will require a round-trip message for pixel readback.)
-</p>
-<p>
-Experiment with the MESA_BACK_BUFFER variable to see which is faster
-for your application.
-</p>
-
-
-<H2>Colormaps</H2>
-<p>
-When using Mesa directly or with GLX, it's up to the application
-writer to create a window with an appropriate colormap. The GLUT
-toolkit tris to minimize colormap <em>flashing</em> by sharing
-colormaps when possible. Specifically, if the visual and depth of the
-window matches that of the root window, the root window's colormap
-will be shared by the Mesa window. Otherwise, a new, private colormap
-will be allocated.
-</p>
-
-<p>
-When sharing the root colormap, Mesa may be unable to allocate the colors
-it needs, resulting in poor color quality. This can happen when a
-large number of colorcells in the root colormap are already allocated.
-To prevent colormap sharing in GLUT, set the
-<b>MESA_PRIVATE_CMAP</b> environment variable. The value isn't
-significant.
-</p>
-
-
-<H2>Gamma Correction</H2>
-<p>
-To compensate for the nonlinear relationship between pixel values
-and displayed intensities, there is a gamma correction feature in
-Mesa. Some systems, such as Silicon Graphics, support gamma
-correction in hardware (man gamma) so you won't need to use Mesa's
-gamma facility. Other systems, however, may need gamma adjustment
-to produce images which look correct. If you believe that
-Mesa's images are too dim, read on.
-</p>
-
-<p>
-Gamma correction is controlled with the <b>MESA_GAMMA</b> environment
-variable. Its value is of the form <b>Gr Gg Gb</b> or just <b>G</b> where
-Gr is the red gamma value, Gg is the green gamma value, Gb is the
-blue gamma value and G is one gamma value to use for all three
-channels. Each value is a positive real number typically in the
-range 1.0 to 2.5.
-The defaults are all 1.0, effectively disabling gamma correction.
-Examples:
-</p>
-<pre>
- % export MESA_GAMMA="2.3 2.2 2.4" // separate R,G,B values
- % export MESA_GAMMA="2.0" // same gamma for R,G,B
-</pre>
-<p>
-The progs/demos/gamma.c program may help you to determine reasonable gamma
-value for your display. With correct gamma values, the color intensities
-displayed in the top row (drawn by dithering) should nearly match those
-in the bottom row (drawn as grays).
-</p>
-
-<p>
-Alex De Bruyn reports that gamma values of 1.6, 1.6 and 1.9 work well
-on HP displays using the HP-ColorRecovery technology.
-</p>
-
-<p>
-Mesa implements gamma correction with a lookup table which translates
-a "linear" pixel value to a gamma-corrected pixel value. There is a
-small performance penalty. Gamma correction only works in RGB mode.
-Also be aware that pixel values read back from the frame buffer will
-not be "un-corrected" so glReadPixels may not return the same data
-drawn with glDrawPixels.
-</p>
-
-<p>
-For more information about gamma correction see:
-<a href="http://www.inforamp.net/~poynton/notes/colour_and_gamma/GammaFAQ.html"
-the Gamma FAQ</a>
-</p>
-
-
-<H2>Overlay Planes</H2>
-<p>
-Hardware overlay planes are supported by the Xlib driver. To
-determine if your X server has overlay support you can test for the
-SERVER_OVERLAY_VISUALS property:
-</p>
-<pre>
- xprop -root | grep SERVER_OVERLAY_VISUALS
-</pre>
-
-
-<H2>HPCR Dithering</H2>
-<p>
-If you set the <b>MESA_HPCR_CLEAR</b> environment variable then dithering
-will be used when clearing the color buffer. This is only applicable
-to HP systems with the HPCR (Color Recovery) feature.
-This incurs a small performance penalty.
-</p>
-
-
-<H2>Extensions</H2>
-<p>
-The following MESA-specific extensions are implemented in the Xlib driver.
-</p>
-
-<h3>GLX_MESA_pixmap_colormap</h3>
-
-<p>
-This extension adds the GLX function:
-</p>
-<pre>
- GLXPixmap glXCreateGLXPixmapMESA( Display *dpy, XVisualInfo *visual,
- Pixmap pixmap, Colormap cmap )
-</pre>
-<p>
-It is an alternative to the standard glXCreateGLXPixmap() function.
-Since Mesa supports RGB rendering into any X visual, not just True-
-Color or DirectColor, Mesa needs colormap information to convert RGB
-values into pixel values. An X window carries this information but a
-pixmap does not. This function associates a colormap to a GLX pixmap.
-See the xdemos/glxpixmap.c file for an example of how to use this
-extension.
-</p>
-<p>
-<a href="MESA_pixmap_colormap.spec">GLX_MESA_pixmap_colormap specification</a>
-</p>
-
-
-<h3>GLX_MESA_release_buffers</h3>
-<p>
-Mesa associates a set of ancillary (depth, accumulation, stencil and
-alpha) buffers with each X window it draws into. These ancillary
-buffers are allocated for each X window the first time the X window
-is passed to glXMakeCurrent(). Mesa, however, can't detect when an
-X window has been destroyed in order to free the ancillary buffers.
-</p>
-<p>
-The best it can do is to check for recently destroyed windows whenever
-the client calls the glXCreateContext() or glXDestroyContext()
-functions. This may not be sufficient in all situations though.
-</p>
-<p>
-The GLX_MESA_release_buffers extension allows a client to explicitly
-deallocate the ancillary buffers by calling glxReleaseBuffersMESA()
-just before an X window is destroyed. For example:
-</p>
-<pre>
- #ifdef GLX_MESA_release_buffers
- glXReleaseBuffersMESA( dpy, window );
- #endif
- XDestroyWindow( dpy, window );
-</pre>
-<p>
-<a href="MESA_release_buffers.spec">GLX_MESA_release_buffers specification</a>
-</p>
-<p>
-This extension was added in Mesa 2.0.
-</p>
-
-<H3>GLX_MESA_copy_sub_buffer</H3>
-<p>
-This extension adds the glXCopySubBufferMESA() function. It works
-like glXSwapBuffers() but only copies a sub-region of the window
-instead of the whole window.
-</p>
-<p>
-<a href="MESA_copy_sub_buffer.spec">GLX_MESA_copy_sub_buffer specification</a>
-</p>
-<p>
-This extension was added in Mesa 2.6
-</p>
-
-<h2>Summary of X-related environment variables</H2>

-Welcome to Mesa's GLSL compiler. A brief overview of how things flow:
-
-1) lex and yacc-based preprocessor takes the incoming shader string
-and produces a new string containing the preprocessed shader. This
-takes care of things like #if, #ifdef, #define, and preprocessor macro
-invocations. Note that #version, #extension, and some others are
-passed straight through. See glcpp/*
-
-2) lex and yacc-based parser takes the preprocessed string and
-generates the AST (abstract syntax tree). Almost no checking is
-performed in this stage. See glsl_lexer.lpp and glsl_parser.ypp.
-
-3) The AST is converted to "HIR". This is the intermediate
-representation of the compiler. Constructors are generated, function
-calls are resolved to particular function signatures, and all the
-semantic checking is performed. See ast_*.cpp for the conversion, and
-ir.h for the IR structures.
-
-4) The driver (Mesa, or main.cpp for the standalone binary) performs
-optimizations. These include copy propagation, dead code elimination,
-constant folding, and others. Generally the driver will call
-optimizations in a loop, as each may open up opportunities for other
-optimizations to do additional work. See most files called ir_*.cpp
-
-5) linking is performed. This does checking to ensure that the
-outputs of the vertex shader match the inputs of the fragment shader,
-and assigns locations to uniforms, attributes, and varyings. See
-linker.cpp.
-
-6) The driver may perform additional optimization at this point, as
-for example dead code elimination previously couldn't remove functions
-or global variable usage when we didn't know what other code would be
-linked in.
-
-7) The driver performs code generation out of the IR, taking a linked
-shader program and producing a compiled program for each stage. See
-ir_to_mesa.cpp for Mesa IR code generation.
-
-FAQ:
-
-Q: What is HIR versus IR versus LIR?
-
-A: The idea behind the naming was that ast_to_hir would produce a
-high-level IR ("HIR"), with things like matrix operations, structure
-assignments, etc., present. A series of lowering passes would occur
-that do things like break matrix multiplication into a series of dot
-products/MADs, make structure assignment be a series of assignment of
-components, flatten if statements into conditional moves, and such,
-producing a low level IR ("LIR").
-
-However, it now appears that each driver will have different
-requirements from a LIR. A 915-generation chipset wants all functions
-inlined, all loops unrolled, all ifs flattened, no variable array
-accesses, and matrix multiplication broken down. The Mesa IR backend
-for swrast would like matrices and structure assignment broken down,
-but it can support function calls and dynamic branching. A 965 vertex
-shader IR backend could potentially even handle some matrix operations
-without breaking them down, but the 965 fragment shader IR backend
-would want to break to have (almost) all operations down channel-wise
-and perform optimization on that. As a result, there's no single
-low-level IR that will make everyone happy. So that usage has fallen
-out of favor, and each driver will perform a series of lowering passes
-to take the HIR down to whatever restrictions it wants to impose
-before doing codegen.
-
-Q: How is the IR structured?
-
-A: The best way to get started seeing it would be to run the
-standalone compiler against a shader:
-
-./glsl_compiler --dump-lir \
- ~/src/piglit/tests/shaders/glsl-orangebook-ch06-bump.frag
-
-So for example one of the ir_instructions in main() contains:
-
-(assign (constant bool (1)) (var_ref litColor) (expression vec3 * (var_ref Surf
-aceColor) (var_ref __retval) ) )
-
-Or more visually:
- (assign)
- / | \
- (var_ref) (expression *) (constant bool 1)
- / / \
-(litColor) (var_ref) (var_ref)
- / \
- (SurfaceColor) (__retval)
-
-which came from:
-
-litColor = SurfaceColor * max(dot(normDelta, LightDir), 0.0);
-
-(the max call is not represented in this expression tree, as it was a
-function call that got inlined but not brought into this expression
-tree)
-
-Each of those nodes is a subclass of ir_instruction. A particular
-ir_instruction instance may only appear once in the whole IR tree with
-the exception of ir_variables, which appear once as variable
-declarations:
-
-(declare () vec3 normDelta)
-
-and multiple times as the targets of variable dereferences:
-...
-(assign (constant bool (1)) (var_ref __retval) (expression float dot
- (var_ref normDelta) (var_ref LightDir) ) )
-...
-(assign (constant bool (1)) (var_ref __retval) (expression vec3 -
- (var_ref LightDir) (expression vec3 * (constant float (2.000000))
- (expression vec3 * (expression float dot (var_ref normDelta) (var_ref
- LightDir) ) (var_ref normDelta) ) ) ) )
-...
-
-Each node has a type. Expressions may involve several different types:
-(declare (uniform ) mat4 gl_ModelViewMatrix)
-((assign (constant bool (1)) (var_ref constructor_tmp) (expression
- vec4 * (var_ref gl_ModelViewMatrix) (var_ref gl_Vertex) ) )
-
-An expression tree can be arbitrarily deep, and the compiler tries to
-keep them structured like that so that things like algebraic
-optimizations ((color * 1.0 == color) and ((mat1 * mat2) * vec == mat1
-* (mat2 * vec))) or recognizing operation patterns for code generation
-(vec1 * vec2 + vec3 == mad(vec1, vec2, vec3)) are easier. This comes
-at the expense of additional trickery in implementing some
-optimizations like CSE where one must navigate an expression tree.
-
-Q: Why no SSA representation?
-
-A: Converting an IR tree to SSA form makes dead code elmimination,
-common subexpression elimination, and many other optimizations much
-easier. However, in our primarily vector-based language, there's some
-major questions as to how it would work. Do we do SSA on the scalar
-or vector level? If we do it at the vector level, we're going to end
-up with many different versions of the variable when encountering code
-like:
-
-(assign (constant bool (1)) (swiz x (var_ref __retval) ) (var_ref a) )
-(assign (constant bool (1)) (swiz y (var_ref __retval) ) (var_ref b) )
-(assign (constant bool (1)) (swiz z (var_ref __retval) ) (var_ref c) )
-
-If every masked update of a component relies on the previous value of
-the variable, then we're probably going to be quite limited in our
-dead code elimination wins, and recognizing common expressions may
-just not happen. On the other hand, if we operate channel-wise, then
-we'll be prone to optimizing the operation on one of the channels at
-the expense of making its instruction flow different from the other
-channels, and a vector-based GPU would end up with worse code than if
-we didn't optimize operations on that channel!
-
-Once again, it appears that our optimization requirements are driven
-significantly by the target architecture. For now, targeting the Mesa
-IR backend, SSA does not appear to be that important to producing
-excellent code, but we do expect to do some SSA-based optimizations
-for the 965 fragment shader backend when that is developed.
-
-Q: How should I expand instructions that take multiple backend instructions?
-
-Sometimes you'll have to do the expansion in your code generation --
-see, for example, ir_to_mesa.cpp's handling of ir_unop_sqrt. However,
-in many cases you'll want to do a pass over the IR to convert
-non-native instructions to a series of native instructions. For
-example, for the Mesa backend we have ir_div_to_mul_rcp.cpp because
-Mesa IR (and many hardware backends) only have a reciprocal
-instruction, not a divide. Implementing non-native instructions this
-way gives the chance for constant folding to occur, so (a / 2.0)
-becomes (a * 0.5) after codegen instead of (a * (1.0 / 2.0))
-
-Q: How shoud I handle my special hardware instructions with respect to IR?
-
-Our current theory is that if multiple targets have an instruction for
-some operation, then we should probably be able to represent that in
-the IR. Generally this is in the form of an ir_{bin,un}op expression
-type. For example, we initially implemented fract() using (a -
-floor(a)), but both 945 and 965 have instructions to give that result,
-and it would also simplify the implementation of mod(), so
-ir_unop_fract was added. The following areas need updating to add a
-new expression type:
-
-ir.h (new enum)
-ir.cpp:get_num_operands() (used for ir_reader)
-ir.cpp:operator_strs (used for ir_reader)
-ir_constant_expression.cpp (you probably want to be able to constant fold)
-ir_validate.cpp (check users have the right types)
-
-You may also need to update the backends if they will see the new expr type:
-
-../mesa/shaders/ir_to_mesa.cpp
-
-You can then use the new expression from builtins (if all backends
-would rather see it), or scan the IR and convert to use your new
-expression type (see ir_mod_to_fract, for example).
-
-Q: How is memory management handled in the compiler?
-
-The hierarchical memory allocator "talloc" developed for the Samba
-project is used, so that things like optimization passes don't have to
-worry about their garbage collection so much. It has a few nice
-features, including low performance overhead and good debugging
-support that's trivially available.
-
-Generally, each stage of the compile creates a talloc context and
-allocates its memory out of that or children of it. At the end of the
-stage, the pieces still live are stolen to a new context and the old
-one freed, or the whole context is kept for use by the next stage.
-
-For IR transformations, a temporary context is used, then at the end
-of all transformations, reparent_ir reparents all live nodes under the
-shader's IR list, and the old context full of dead nodes is freed.
-When developing a single IR transformation pass, this means that you
-want to allocate instruction nodes out of the temporary context, so if
-it becomes dead it doesn't live on as the child of a live node. At
-the moment, optimization passes aren't passed that temporary context,
-so they find it by calling talloc_parent() on a nearby IR node. The
-talloc_parent() call is expensive, so many passes will cache the
-result of the first talloc_parent(). Cleaning up all the optimization
-passes to take a context argument and not call talloc_parent() is left
-as an exercise.
-
-Q: What is the file naming convention in this directory?
-
-Initially, there really wasn't one. We have since adopted one:
-
- - Files that implement code lowering passes should be named lower_*
- (e.g., lower_noise.cpp).
- - Files that implement optimization passes should be named opt_*.
- - Files that implement a class that is used throught the code should
- take the name of that class (e.g., ir_hierarchical_visitor.cpp).
- - Files that contain code not fitting in one of the previous
- categories should have a sensible name (e.g., glsl_parser.ypp).

-/**
- * \file ast_to_hir.c
- * Convert abstract syntax to to high-level intermediate reprensentation (HIR).
- *
- * During the conversion to HIR, the majority of the symantic checking is
- * preformed on the program. This includes:
- *
- * * Symbol table management
- * * Type checking
- * * Function binding
- *
- * The majority of this work could be done during parsing, and the parser could
- * probably generate HIR directly. However, this results in frequent changes
- * to the parser code. Since we do not assume that every system this complier
- * is built on will have Flex and Bison installed, we have to store the code
- * generated by these tools in our version control system. In other parts of
- * the system we've seen problems where a parser was changed but the generated
- * code was not committed, merge conflicts where created because two developers
- * had slightly different versions of Bison installed, etc.
- *
- * I have also noticed that running Bison generated parsers in GDB is very
- * irritating. When you get a segfault on '$$ = $1->foo', you can't very
- * well 'print $1' in GDB.
- *
- * As a result, my preference is to put as little C code as possible in the
- * parser (and lexer) sources.

-glcpp -- GLSL "C" preprocessor
-
-This is a simple preprocessor designed to provide the preprocessing
-needs of the GLSL language. The requirements for this preprocessor are
-specified in the GLSL 1.30 specification availble from:
-
-http://www.opengl.org/registry/doc/GLSLangSpec.Full.1.30.10.pdf
-
-This specification is not precise on some semantics, (for example,
-#define and #if), defining these merely "as is standard for C++
-preprocessors". To fill in these details, I've been using a draft of
-the C99 standard as available from:
-
-http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1256.pdf
-
-Any downstream compiler accepting output from glcpp should be prepared
-to encounter and deal with the following preprocessor macros:
-
- #line
- #pragma
- #extension
-
-All other macros will be handles according to the GLSL specification
-and will not appear in the output.
-
-Known limitations
------------------
-The __LINE__ and __FILE__ macros are not yet supported.
-
-A file that ends with a function-like macro name as the last
-non-whitespace token will result in a parse error, (where it should be
-passed through as is).
\ No newline at end of file

-/**
- * Base class of hierarchical visitors of IR instruction trees
- *
- * Hierarchical visitors differ from traditional visitors in a couple of
- * important ways. Rather than having a single \c visit method for each
- * subclass in the composite, there are three kinds of visit methods.
- * Leaf-node classes have a traditional \c visit method. Internal-node
- * classes have a \c visit_enter method, which is invoked just before
- * processing child nodes, and a \c visit_leave method which is invoked just
- * after processing child nodes.
- *
- * In addition, each visit method and the \c accept methods in the composite
- * have a return value which guides the navigation. Any of the visit methods
- * can choose to continue visiting the tree as normal (by returning \c
- * visit_continue), terminate visiting any further nodes immediately (by
- * returning \c visit_stop), or stop visiting sibling nodes (by returning \c
- * visit_continue_with_parent).
- *
- * These two changes combine to allow nagivation of children to be implemented
- * in the composite's \c accept method. The \c accept method for a leaf-node
- * class will simply call the \c visit method, as usual, and pass its return
- * value on. The \c accept method for internal-node classes will call the \c
- * visit_enter method, call the \c accpet method of each child node, and,
- * finally, call the \c visit_leave method. If any of these return a value
- * other that \c visit_continue, the correct action must be taken.
- *
- * The final benefit is that the hierarchical visitor base class need not be
- * abstract. Default implementations of every \c visit, \c visit_enter, and
- * \c visit_leave method can be provided. By default each of these methods
- * simply returns \c visit_continue. This allows a significant reduction in
- * derived class code.
- *
- * For more information about hierarchical visitors, see:
- *
- * http://c2.com/cgi/wiki?HierarchicalVisitorPattern

-/**
- * \file linker.cpp
- * GLSL linker implementation
- *
- * Given a set of shaders that are to be linked to generate a final program,
- * there are three distinct stages.
- *
- * In the first stage shaders are partitioned into groups based on the shader
- * type. All shaders of a particular type (e.g., vertex shaders) are linked
- * together.
- *
- * - Undefined references in each shader are resolve to definitions in
- * another shader.
- * - Types and qualifiers of uniforms, outputs, and global variables defined
- * in multiple shaders with the same name are verified to be the same.
- * - Initializers for uniforms and global variables defined
- * in multiple shaders with the same name are verified to be the same.
- *
- * The result, in the terminology of the GLSL spec, is a set of shader
- * executables for each processing unit.
- *
- * After the first stage is complete, a series of semantic checks are performed
- * on each of the shader executables.
- *
- * - Each shader executable must define a \c main function.
- * - Each vertex shader executable must write to \c gl_Position.
- * - Each fragment shader executable must write to either \c gl_FragData or
- * \c gl_FragColor.
- *
- * In the final stage individual shader executables are linked to create a
- * complete exectuable.
- *
- * - Types of uniforms defined in multiple shader stages with the same name
- * are verified to be the same.
- * - Initializers for uniforms defined in multiple shader stages with the
- * same name are verified to be the same.
- * - Types and qualifiers of outputs defined in one stage are verified to
- * be the same as the types and qualifiers of inputs defined with the same
- * name in a later stage.

-/**
- * \file list.h
- * \brief Doubly-linked list abstract container type.
- *
- * Each doubly-linked list has a sentinel head and tail node. These nodes
- * contain no data. The head sentinel can be identified by its \c prev
- * pointer being \c NULL. The tail sentinel can be identified by its
- * \c next pointer being \c NULL.
- *
- * A list is empty if either the head sentinel's \c next pointer points to the
- * tail sentinel or the tail sentinel's \c prev poiner points to the head
- * sentinel.
- *
- * Instead of tracking two separate \c node structures and a \c list structure
- * that points to them, the sentinel nodes are in a single structure. Noting
- * that each sentinel node always has one \c NULL pointer, the \c NULL
- * pointers occupy the same memory location. In the \c list structure
- * contains a the following:
- *
- * - A \c head pointer that represents the \c next pointer of the
- * head sentinel node.
- * - A \c tail pointer that represents the \c prev pointer of the head
- * sentinel node and the \c next pointer of the tail sentinel node. This
- * pointer is \b always \c NULL.
- * - A \c tail_prev pointer that represents the \c prev pointer of the
- * tail sentinel node.
- *
- * Therefore, if \c head->next is \c NULL or \c tail_prev->prev is \c NULL,
- * the list is empty.
- *
- * To anyone familiar with "exec lists" on the Amiga, this structure should
- * be immediately recognizable. See the following link for the original Amiga
- * operating system documentation on the subject.
- *

-/**
- * \file lower_instructions.cpp
- *
- * Many GPUs lack native instructions for certain expression operations, and
- * must replace them with some other expression tree. This pass lowers some
- * of the most common cases, allowing the lowering code to be implemented once
- * rather than in each driver backend.
- *
- * Currently supported transformations:
- * - SUB_TO_ADD_NEG
- * - DIV_TO_MUL_RCP
- * - EXP_TO_EXP2
- * - POW_TO_EXP2
- * - LOG_TO_LOG2
- * - MOD_TO_FRACT
- *
- * SUB_TO_ADD_NEG:
- * ---------------
- * Breaks an ir_binop_sub expression down to add(op0, neg(op1))
- *
- * This simplifies expression reassociation, and for many backends
- * there is no subtract operation separate from adding the negation.
- * For backends with native subtract operations, they will probably
- * want to recognize add(op0, neg(op1)) or the other way around to
- * produce a subtract anyway.
- *
- * DIV_TO_MUL_RCP:
- * ---------------
- * Breaks an ir_unop_div expression down to op0 * (rcp(op1)).
- *
- * Many GPUs don't have a divide instruction (945 and 965 included),
- * but they do have an RCP instruction to compute an approximate
- * reciprocal. By breaking the operation down, constant reciprocals
- * can get constant folded.
- *
- * EXP_TO_EXP2 and LOG_TO_LOG2:
- * ----------------------------
- * Many GPUs don't have a base e log or exponent instruction, but they
- * do have base 2 versions, so this pass converts exp and log to exp2
- * and log2 operations.
- *
- * POW_TO_EXP2:
- * -----------
- * Many older GPUs don't have an x**y instruction. For these GPUs, convert
- * x**y to 2**(y * log2(x)).
- *
- * MOD_TO_FRACT:
- * -------------
- * Breaks an ir_unop_mod expression down to (op1 * fract(op0 / op1))
- *
- * Many GPUs don't have a MOD instruction (945 and 965 included), and
- * if we have to break it down like this anyway, it gives an
- * opportunity to do things like constant fold the (1.0 / op1) easily.

-/**
- * \file lower_jumps.cpp
- *
- * This pass lowers jumps (break, continue, and return) to if/else structures.
- *
- * It can be asked to:
- * 1. Pull jumps out of ifs where possible
- * 2. Remove all "continue"s, replacing them with an "execute flag"
- * 3. Replace all "break" with a single conditional one at the end of the loop
- * 4. Replace all "return"s with a single return at the end of the function,
- * for the main function and/or other functions
- *
- * Applying this pass gives several benefits:
- * 1. All functions can be inlined.
- * 2. nv40 and other pre-DX10 chips without "continue" can be supported
- * 3. nv30 and other pre-DX10 chips with no control flow at all are better
- * supported
- *
- * Continues are lowered by adding a per-loop "execute flag", initialized to
- * true, that when cleared inhibits all execution until the end of the loop.
- *
- * Breaks are lowered to continues, plus setting a "break flag" that is checked
- * at the end of the loop, and trigger the unique "break".
- *
- * Returns are lowered to breaks/continues, plus adding a "return flag" that
- * causes loops to break again out of their enclosing loops until all the
- * loops are exited: then the "execute flag" logic will ignore everything
- * until the end of the function.
- *
- * Note that "continue" and "return" can also be implemented by adding
- * a dummy loop and using break.
- * However, this is bad for hardware with limited nesting depth, and
- * prevents further optimization, and thus is not currently performed.
