| * DescriptorSetLayoutDef/DescriptorSetLayout classes |
| * |
| * Overview - These two classes encapsulate the Vulkan VkDescriptorSetLayout data (layout). |
| * A layout consists of some number of bindings, each of which has a binding#, a |
| * type, descriptor count, stage flags, and pImmutableSamplers. |
| |
| * The DescriptorSetLayoutDef represents a canonicalization of the input data and contains |
| * neither per handle or per device state. It is possible for different handles on |
| * different devices to share a common def. This is used and useful for quick compatibiltiy |
| * validation. The DescriptorSetLayout refers to a DescriptorSetLayoutDef and contains |
| * all per handle state. |
| * |
| * Index vs Binding - A layout is created with an array of VkDescriptorSetLayoutBinding |
| * where each array index will have a corresponding binding# that is defined in that struct. |
| * The binding#, then, is decoupled from VkDescriptorSetLayoutBinding index, which allows |
| * bindings to be defined out-of-order. This DescriptorSetLayout class, however, stores |
| * the bindings internally in-order. This is useful for operations which may "roll over" |
| * from a single binding to the next consecutive binding. |
| * |
| * Note that although the bindings are stored in-order, there still may be "gaps" in the |
| * binding#. For example, if the binding creation order is 8, 7, 10, 3, 4, then the |
| * internal binding array will have five entries stored in binding order 3, 4, 7, 8, 10. |
| * To process all of the bindings in a layout you can iterate from 0 to GetBindingCount() |
| * and use the Get*FromIndex() functions for each index. To just process a single binding, |
| * use the Get*FromBinding() functions. |
| * |
| * Global Index - The binding vector index has as many indices as there are bindings. |
| * This class also has the concept of a Global Index. For the global index functions, |
| * there are as many global indices as there are descriptors in the layout. |
| * For the global index, consider all of the bindings to be a flat array where |
| * descriptor 0 of of the lowest binding# is index 0 and each descriptor in the layout |
| * increments from there. So if the lowest binding# in this example had descriptorCount of |
| * 10, then the GlobalStartIndex of the 2nd lowest binding# will be 10 where 0-9 are the |
| * global indices for the lowest binding#. |
