+[https://github.com/syoyo/tinyobjloader](https://github.com/syoyo/tinyobjloader)
+
+Tiny but powerful single file wavefront obj loader written in C++. No dependency except for C++ STL. It can parse over 10M polygons with moderate memory and time.
+
+`tinyobjloader` is good for embedding .obj loader to your (global illumination) renderer ;-)
+
+If you are looking for C89 version, please see https://github.com/syoyo/tinyobjloader-c .
+
+Notice!
+-------
+
+We have released new version v1.0.0 on 20 Aug, 2016.

+
+## Usage
+
+### Data format
+
+`attrib_t` contains single and linear array of vertex data(position, normal and texcoord).
+
+```
+attrib_t::vertices => 3 floats per vertex
+
+ v[0] v[1] v[2] v[3] v[n-1]
+ +-----------+-----------+-----------+-----------+ +-----------+
+ | x | y | z | x | y | z | x | y | z | x | y | z | .... | x | y | z |
+ +-----------+-----------+-----------+-----------+ +-----------+
+
+attrib_t::normals => 3 floats per vertex
+
+ n[0] n[1] n[2] n[3] n[n-1]
+ +-----------+-----------+-----------+-----------+ +-----------+
+ | x | y | z | x | y | z | x | y | z | x | y | z | .... | x | y | z |
+ +-----------+-----------+-----------+-----------+ +-----------+
+
+attrib_t::texcoords => 2 floats per vertex
+
+ t[0] t[1] t[2] t[3] t[n-1]
+ +-----------+-----------+-----------+-----------+ +-----------+
+ | u | v | u | v | u | v | u | v | .... | u | v |
+ +-----------+-----------+-----------+-----------+ +-----------+
+
+attrib_t::colors => 3 floats per vertex(vertex color. optional)
+
+ c[0] c[1] c[2] c[3] c[n-1]
+ +-----------+-----------+-----------+-----------+ +-----------+
+ | x | y | z | x | y | z | x | y | z | x | y | z | .... | x | y | z |
+ +-----------+-----------+-----------+-----------+ +-----------+
+
+```
+
+Each `shape_t::mesh_t` does not contain vertex data but contains array index to `attrib_t`.
+See `loader_example.cc` for more details.
+
+
+```
+
+mesh_t::indices => array of vertex indices.
+
+ +----+----+----+----+----+----+----+----+----+----+ +--------+
+ | i0 | i1 | i2 | i3 | i4 | i5 | i6 | i7 | i8 | i9 | ... | i(n-1) |
+ +----+----+----+----+----+----+----+----+----+----+ +--------+
+
+Each index has an array index to attrib_t::vertices, attrib_t::normals and attrib_t::texcoords.
+
+mesh_t::num_face_vertices => array of the number of vertices per face(e.g. 3 = triangle, 4 = quad , 5 or more = N-gons).
+
+
+ +---+---+---+ +---+
+ | 3 | 4 | 3 | ...... | 3 |
+ +---+---+---+ +---+
+ | | | |
+ | | | +-----------------------------------------+
+ | | | |
+ | | +------------------------------+ |
+ | | | |
+ | +------------------+ | |
+ | | | |
+ |/ |/ |/ |/
+
+ mesh_t::indices
+
+ | face[0] | face[1] | face[2] | | face[n-1] |
+ +----+----+----+----+----+----+----+----+----+----+ +--------+--------+--------+
+ | i0 | i1 | i2 | i3 | i4 | i5 | i6 | i7 | i8 | i9 | ... | i(n-3) | i(n-2) | i(n-1) |
+ +----+----+----+----+----+----+----+----+----+----+ +--------+--------+--------+
+
+```
+
+Note that when `triangulate` flas is true in `tinyobj::LoadObj()` argument, `num_face_vertices` are all filled with 3(triangle).
+
+### float data type
+
+TinyObjLoader now use `real_t` for floating point data type.
+Default is `float(32bit)`.
+You can enable `double(64bit)` precision by using `TINYOBJLOADER_USE_DOUBLE` define.
+
+#### Example code
+
+```c++
+#define TINYOBJLOADER_IMPLEMENTATION // define this in only *one* .cc
+#include "tiny_obj_loader.h"
+
+std::string inputfile = "cornell_box.obj";
+tinyobj::attrib_t attrib;
+std::vector<tinyobj::shape_t> shapes;
+std::vector<tinyobj::material_t> materials;
+
+std::string err;
+bool ret = tinyobj::LoadObj(&attrib, &shapes, &materials, &err, inputfile.c_str());
+
+if (!err.empty()) { // `err` may contain warning message.
+ std::cerr << err << std::endl;
+}
+
+if (!ret) {
+ exit(1);
+}
+
+// Loop over shapes
+for (size_t s = 0; s < shapes.size(); s++) {
+ // Loop over faces(polygon)
+ size_t index_offset = 0;
+ for (size_t f = 0; f < shapes[s].mesh.num_face_vertices.size(); f++) {
+ int fv = shapes[s].mesh.num_face_vertices[f];
+
+ // Loop over vertices in the face.
+ for (size_t v = 0; v < fv; v++) {
+ // access to vertex
+ tinyobj::index_t idx = shapes[s].mesh.indices[index_offset + v];
+ tinyobj::real_t vx = attrib.vertices[3*idx.vertex_index+0];
+ tinyobj::real_t vy = attrib.vertices[3*idx.vertex_index+1];
+ tinyobj::real_t vz = attrib.vertices[3*idx.vertex_index+2];

+## Optimized loader
+
+Optimized multi-threaded .obj loader is available at `experimental/` directory.
+If you want absolute performance to load .obj data, this optimized loader will fit your purpose.
+Note that the optimized loader uses C++11 thread and it does less error checks but may work most .obj data.
+
+Here is some benchmark result. Time are measured on MacBook 12(Early 2016, Core m5 1.2GHz).
+
+* Rungholt scene(6M triangles)
+ * old version(v0.9.x): 15500 msecs.
+ * baseline(v1.0.x): 6800 msecs(2.3x faster than old version)
+ * optimised: 1500 msecs(10x faster than old version, 4.5x faster than baseline)
+
+
+## Tests
+
+Unit tests are provided in `tests` directory. See `tests/README.md` for details.

+attempt to find all problems, or to ensure that everything it does
+find is legitimately a problem.
+
+In particular, we can get very confused by /* and // inside strings!
+We do a small hack, which is to ignore //'s with "'s after them on the

+Syntax: cpplint.py [--verbose=#] [--output=vs7] [--filter=-x,+y,...]
+ [--counting=total|toplevel|detailed] [--root=subdir]
+ [--linelength=digits]
+ <file> [file] ...
+
+ The style guidelines this tries to follow are those in
+ http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml
+
+ Every problem is given a confidence score from 1-5, with 5 meaning we are
+ certain of the problem, and 1 meaning it could be a legitimate construct.
+ This will miss some errors, and is not a substitute for a code review.
+
+ To suppress false-positive errors of a certain category, add a
+ 'NOLINT(category)' comment to the line. NOLINT or NOLINT(*)
+ suppresses errors of all categories on that line.
+
+ The files passed in will be linted; at least one file must be provided.
+ Default linted extensions are .cc, .cpp, .cu, .cuh and .h. Change the
+ extensions with the --extensions flag.
+
+ Flags:
+
+ output=vs7
+ By default, the output is formatted to ease emacs parsing. Visual Studio
+ compatible output (vs7) may also be used. Other formats are unsupported.
+
+ verbose=#
+ Specify a number 0-5 to restrict errors to certain verbosity levels.
+
+ filter=-x,+y,...
+ Specify a comma-separated list of category-filters to apply: only
+ error messages whose category names pass the filters will be printed.
+ (Category names are printed with the message and look like
+ "[whitespace/indent]".) Filters are evaluated left to right.
+ "-FOO" and "FOO" means "do not print categories that start with FOO".
+ "+FOO" means "do print categories that start with FOO".
+
+ Examples: --filter=-whitespace,+whitespace/braces
+ --filter=whitespace,runtime/printf,+runtime/printf_format
+ --filter=-,+build/include_what_you_use
+
+ To see a list of all the categories used in cpplint, pass no arg:
+ --filter=
+
+ counting=total|toplevel|detailed
+ The total number of errors found is always printed. If
+ 'toplevel' is provided, then the count of errors in each of
+ the top-level categories like 'build' and 'whitespace' will
+ also be printed. If 'detailed' is provided, then a count
+ is provided for each category like 'build/class'.
+
+ root=subdir
+ The root directory used for deriving header guard CPP variable.
+ By default, the header guard CPP variable is calculated as the relative
+ path to the directory that contains .git, .hg, or .svn. When this flag
+ is specified, the relative path is calculated from the specified
+ directory. If the specified directory does not exist, this flag is
+ ignored.
+
+ Examples:
+ Assuming that src/.git exists, the header guard CPP variables for
+ src/chrome/browser/ui/browser.h are:
+
+ No flag => CHROME_BROWSER_UI_BROWSER_H_
+ --root=chrome => BROWSER_UI_BROWSER_H_
+ --root=chrome/browser => UI_BROWSER_H_
+
+ linelength=digits
+ This is the allowed line length for the project. The default value is
+ 80 characters.
+
+ Examples:
+ --linelength=120
+
+ extensions=extension,extension,...
+ The allowed file extensions that cpplint will check
+
+ Examples:
+ --extensions=hpp,cpp
+
+ cpplint.py supports per-directory configurations specified in CPPLINT.cfg
+ files. CPPLINT.cfg file can contain a number of key=value pairs.
+ Currently the following options are supported:
+
+ set noparent
+ filter=+filter1,-filter2,...
+ exclude_files=regex
+ linelength=80
+
+ "set noparent" option prevents cpplint from traversing directory tree
+ upwards looking for more .cfg files in parent directories. This option
+ is usually placed in the top-level project directory.
+
+ The "filter" option is similar in function to --filter flag. It specifies
+ message filters in addition to the |_DEFAULT_FILTERS| and those specified
+ through --filter command-line flag.
+
+ "exclude_files" allows to specify a regular expression to be matched against
+ a file name. If the expression matches, the file is skipped and not run
+ through liner.
+
+ "linelength" allows to specify the allowed line length for the project.
+
+ CPPLINT.cfg has an effect on files in the same directory and all
+ sub-directories, unless overridden by a nested configuration file.
+
+ Example file:
+ filter=-build/include_order,+build/include_alpha
+ exclude_files=.*\.cc
+
+ The above example disables build/include_order warning and enables
+ build/include_alpha as well as excludes all .cc from being
+ processed by linter, in the current directory (where the .cfg
+ file is located) and all sub-directories.
+"""

+
+
+ QUICK NOTES:
+ Primarily of interest to game developers and other people who can
+ avoid problematic images and only need the trivial interface
+
+ JPEG baseline & progressive (12 bpc/arithmetic not supported, same as stock IJG lib)
+ PNG 1/2/4/8-bit-per-channel (16 bpc not supported)
+
+ TGA (not sure what subset, if a subset)
+ BMP non-1bpp, non-RLE
+ PSD (composited view only, no extra channels, 8/16 bit-per-channel)
+
+ GIF (*comp always reports as 4-channel)
+ HDR (radiance rgbE format)
+ PIC (Softimage PIC)
+ PNM (PPM and PGM binary only)
+
+ Animated GIF still needs a proper API, but here's one way to do it:
+ http://gist.github.com/urraka/685d9a6340b26b830d49
+
+ - decode from memory or through FILE (define STBI_NO_STDIO to remove code)
+ - decode from arbitrary I/O callbacks
+ - SIMD acceleration on x86/x64 (SSE2) and ARM (NEON)
+
+ Full documentation under "DOCUMENTATION" below.
+
+
+ Revision 2.00 release notes:
+
+ - Progressive JPEG is now supported.
+
+ - PPM and PGM binary formats are now supported, thanks to Ken Miller.
+
+ - x86 platforms now make use of SSE2 SIMD instructions for
+ JPEG decoding, and ARM platforms can use NEON SIMD if requested.
+ This work was done by Fabian "ryg" Giesen. SSE2 is used by
+ default, but NEON must be enabled explicitly; see docs.
+
+ With other JPEG optimizations included in this version, we see
+ 2x speedup on a JPEG on an x86 machine, and a 1.5x speedup
+ on a JPEG on an ARM machine, relative to previous versions of this
+ library. The same results will not obtain for all JPGs and for all
+ x86/ARM machines. (Note that progressive JPEGs are significantly
+ slower to decode than regular JPEGs.) This doesn't mean that this
+ is the fastest JPEG decoder in the land; rather, it brings it
+ closer to parity with standard libraries. If you want the fastest
+ decode, look elsewhere. (See "Philosophy" section of docs below.)
+
+ See final bullet items below for more info on SIMD.
+
+ - Added STBI_MALLOC, STBI_REALLOC, and STBI_FREE macros for replacing
+ the memory allocator. Unlike other STBI libraries, these macros don't
+ support a context parameter, so if you need to pass a context in to
+ the allocator, you'll have to store it in a global or a thread-local
+ variable.
+
+ - Split existing STBI_NO_HDR flag into two flags, STBI_NO_HDR and
+ STBI_NO_LINEAR.
+ STBI_NO_HDR: suppress implementation of .hdr reader format
+ STBI_NO_LINEAR: suppress high-dynamic-range light-linear float API
+
+ - You can suppress implementation of any of the decoders to reduce
+ your code footprint by #defining one or more of the following
+ symbols before creating the implementation.
+
+ STBI_NO_JPEG
+ STBI_NO_PNG
+ STBI_NO_BMP
+ STBI_NO_PSD
+ STBI_NO_TGA
+ STBI_NO_GIF
+ STBI_NO_HDR
+ STBI_NO_PIC
+ STBI_NO_PNM (.ppm and .pgm)
+
+ - You can request *only* certain decoders and suppress all other ones
+ (this will be more forward-compatible, as addition of new decoders
+ doesn't require you to disable them explicitly):
+
+ STBI_ONLY_JPEG
+ STBI_ONLY_PNG
+ STBI_ONLY_BMP
+ STBI_ONLY_PSD
+ STBI_ONLY_TGA
+ STBI_ONLY_GIF
+ STBI_ONLY_HDR
+ STBI_ONLY_PIC
+ STBI_ONLY_PNM (.ppm and .pgm)
+
+ Note that you can define multiples of these, and you will get all
+ of them ("only x" and "only y" is interpreted to mean "only x&y").
+
+ - If you use STBI_NO_PNG (or _ONLY_ without PNG), and you still
+ want the zlib decoder to be available, #define STBI_SUPPORT_ZLIB
+
+ - Compilation of all SIMD code can be suppressed with
+ #define STBI_NO_SIMD
+ It should not be necessary to disable SIMD unless you have issues
+ compiling (e.g. using an x86 compiler which doesn't support SSE
+ intrinsics or that doesn't support the method used to detect
+ SSE2 support at run-time), and even those can be reported as
+ bugs so I can refine the built-in compile-time checking to be
+ smarter.
+
+ - The old STBI_SIMD system which allowed installing a user-defined
+ IDCT etc. has been removed. If you need this, don't upgrade. My
+ assumption is that almost nobody was doing this, and those who
+ were will find the built-in SIMD more satisfactory anyway.
+
+ - RGB values computed for JPEG images are slightly different from
+ previous versions of stb_image. (This is due to using less
+ integer precision in SIMD.) The C code has been adjusted so
+ that the same RGB values will be computed regardless of whether
+ SIMD support is available, so your app should always produce
+ consistent results. But these results are slightly different from
+ previous versions. (Specifically, about 3% of available YCbCr values
+ will compute different RGB results from pre-1.49 versions by +-1;
+ most of the deviating values are one smaller in the G channel.)
+
+ - If you must produce consistent results with previous versions of
+ stb_image, #define STBI_JPEG_OLD and you will get the same results
+ you used to; however, you will not get the SIMD speedups for
+ the YCbCr-to-RGB conversion step (although you should still see
+ significant JPEG speedup from the other changes).
+
+ Please note that STBI_JPEG_OLD is a temporary feature; it will be
+ removed in future versions of the library. It is only intended for
+ near-term back-compatibility use.

+// Basic usage (see HDR discussion below for HDR usage):
+// int x,y,n;
+// unsigned char *data = stbi_load(filename, &x, &y, &n, 0);
+// // ... process data if not NULL ...
+// // ... x = width, y = height, n = # 8-bit components per pixel ...
+// // ... replace '0' with '1'..'4' to force that many components per pixel
+// // ... but 'n' will always be the number that it would have been if you said 0
+// stbi_image_free(data)
+//
+// Standard parameters:
+// int *x -- outputs image width in pixels
+// int *y -- outputs image height in pixels
+// int *comp -- outputs # of image components in image file
+// int req_comp -- if non-zero, # of image components requested in result
+//
+// The return value from an image loader is an 'unsigned char *' which points
+// to the pixel data, or NULL on an allocation failure or if the image is
+// corrupt or invalid. The pixel data consists of *y scanlines of *x pixels,
+// with each pixel consisting of N interleaved 8-bit components; the first
+// pixel pointed to is top-left-most in the image. There is no padding between
+// image scanlines or between pixels, regardless of format. The number of
+// components N is 'req_comp' if req_comp is non-zero, or *comp otherwise.
+// If req_comp is non-zero, *comp has the number of components that _would_
+// have been output otherwise. E.g. if you set req_comp to 4, you will always
+// get RGBA output, but you can check *comp to see if it's trivially opaque
+// because e.g. there were only 3 channels in the source image.
+//
+// An output image with N components has the following components interleaved
+// in this order in each pixel:
+//
+// N=#comp components
+// 1 grey
+// 2 grey, alpha
+// 3 red, green, blue
+// 4 red, green, blue, alpha
+//
+// If image loading fails for any reason, the return value will be NULL,
+// and *x, *y, *comp will be unchanged. The function stbi_failure_reason()
+// can be queried for an extremely brief, end-user unfriendly explanation
+// of why the load failed. Define STBI_NO_FAILURE_STRINGS to avoid
+// compiling these strings at all, and STBI_FAILURE_USERMSG to get slightly
+// more user-friendly ones.
+//
+// Paletted PNG, BMP, GIF, and PIC images are automatically depalettized.
+//
+// ===========================================================================
+//
+// Philosophy
+//
+// stb libraries are designed with the following priorities:
+//
+// 1. easy to use
+// 2. easy to maintain
+// 3. good performance
+//
+// Sometimes I let "good performance" creep up in priority over "easy to maintain",
+// and for best performance I may provide less-easy-to-use APIs that give higher
+// performance, in addition to the easy to use ones. Nevertheless, it's important
+// to keep in mind that from the standpoint of you, a client of this library,
+// all you care about is #1 and #3, and stb libraries do not emphasize #3 above all.
+//
+// Some secondary priorities arise directly from the first two, some of which
+// make more explicit reasons why performance can't be emphasized.
+//
+// - Portable ("ease of use")
+// - Small footprint ("easy to maintain")
+// - No dependencies ("ease of use")
+//
+// ===========================================================================
+//
+// I/O callbacks
+//
+// I/O callbacks allow you to read from arbitrary sources, like packaged
+// files or some other source. Data read from callbacks are processed
+// through a small internal buffer (currently 128 bytes) to try to reduce
+// overhead.
+//
+// The three functions you must define are "read" (reads some bytes of data),
+// "skip" (skips some bytes of data), "eof" (reports if the stream is at the end).
+//
+// ===========================================================================
+//
+// SIMD support
+//
+// The JPEG decoder will try to automatically use SIMD kernels on x86 when
+// supported by the compiler. For ARM Neon support, you must explicitly
+// request it.
+//
+// (The old do-it-yourself SIMD API is no longer supported in the current
+// code.)
+//
+// On x86, SSE2 will automatically be used when available based on a run-time
+// test; if not, the generic C versions are used as a fall-back. On ARM targets,
+// the typical path is to have separate builds for NEON and non-NEON devices
+// (at least this is true for iOS and Android). Therefore, the NEON support is
+// toggled by a build flag: define STBI_NEON to get NEON loops.
+//
+// The output of the JPEG decoder is slightly different from versions where
+// SIMD support was introduced (that is, for versions before 1.49). The
+// difference is only +-1 in the 8-bit RGB channels, and only on a small
+// fraction of pixels. You can force the pre-1.49 behavior by defining
+// STBI_JPEG_OLD, but this will disable some of the SIMD decoding path
+// and hence cost some performance.
+//
+// If for some reason you do not want to use any of SIMD code, or if
+// you have issues compiling it, you can disable it entirely by
+// defining STBI_NO_SIMD.
+//
+// ===========================================================================
+//
+// HDR image support (disable by defining STBI_NO_HDR)
+//
+// stb_image now supports loading HDR images in general, and currently
+// the Radiance .HDR file format, although the support is provided
+// generically. You can still load any file through the existing interface;
+// if you attempt to load an HDR file, it will be automatically remapped to
+// LDR, assuming gamma 2.2 and an arbitrary scale factor defaulting to 1;
+// both of these constants can be reconfigured through this interface:
+//
+// stbi_hdr_to_ldr_gamma(2.2f);
+// stbi_hdr_to_ldr_scale(1.0f);
+//
+// (note, do not use _inverse_ constants; stbi_image will invert them
+// appropriately).
+//
+// Additionally, there is a new, parallel interface for loading files as
+// (linear) floats to preserve the full dynamic range:
+//
+// float *data = stbi_loadf(filename, &x, &y, &n, 0);
+//
+// If you load LDR images through this interface, those images will
+// be promoted to floating point values, run through the inverse of
+// constants corresponding to the above:
+//
+// stbi_ldr_to_hdr_scale(1.0f);
+// stbi_ldr_to_hdr_gamma(2.2f);
+//
+// Finally, given a filename (or an open file or memory block--see header
+// file for details) containing image data, you can query for the "most
+// appropriate" interface to use (that is, whether the image is HDR or
+// not), using:
+//
+// stbi_is_hdr(char *filename);
+//
+// ===========================================================================
+//
+// iPhone PNG support:
+//
+// By default we convert iphone-formatted PNGs back to RGB, even though
+// they are internally encoded differently. You can disable this conversion
+// by by calling stbi_convert_iphone_png_to_rgb(0), in which case
+// you will always just get the native iphone "format" through (which
+// is BGR stored in RGB).
+//
+// Call stbi_set_unpremultiply_on_load(1) as well to force a divide per
+// pixel to remove any premultiplied alpha *only* if the image file explicitly
+// says there's premultiplied data (currently only happens in iPhone images,
+// and only if iPhone convert-to-rgb processing is on).

+// based on our allocator will share the same stack buffer.
+//
+// This stack buffer implementation is very simple. The first allocation that
+// fits in the stack buffer will use the stack buffer. Any subsequent
+// allocations will not use the stack buffer, even if there is unused room.
+// This makes it appropriate for array-like containers, but the caller should
