2022-06-22	Cleanup: remove redundant GPU headers	Campbell Barton

2022-02-11	File headers: SPDX License migration	Campbell Barton
	Use a shorter/simpler license convention, stops the header taking so much space. Follow the SPDX license specification: https://spdx.org/licenses - C/C++/objc/objc++ - Python - Shell Scripts - CMake, GNUmakefile While most of the source tree has been included - `./extern/` was left out. - `./intern/cycles` & `./intern/atomic` are also excluded because they use different header conventions. doc/license/SPDX-license-identifiers.txt has been added to list SPDX all used identifiers. See P2788 for the script that automated these edits. Reviewed By: brecht, mont29, sergey Ref D14069
2021-12-27	OpenSubDiv: add support for an OpenGL evaluator	Kévin Dietrich
	This evaluator is used in order to evaluate subdivision at render time, allowing for faster renders of meshes with a subdivision surface modifier placed at the last position in the modifier list. When evaluating the subsurf modifier, we detect whether we can delegate evaluation to the draw code. If so, the subdivision is first evaluated on the GPU using our own custom evaluator (only the coarse data needs to be initially sent to the GPU), then, buffers for the final `MeshBufferCache` are filled on the GPU using a set of compute shaders. However, some buffers are still filled on the CPU side, if doing so on the GPU is impractical (e.g. the line adjacency buffer used for x-ray, whose logic is hardly GPU compatible). This is done at the mesh buffer extraction level so that the result can be readily used in the various OpenGL engines, without having to write custom geometry or tesselation shaders. We use our own subdivision evaluation shaders, instead of OpenSubDiv's vanilla one, in order to control the data layout, and interpolation. For example, we store vertex colors as compressed 16-bit integers, while OpenSubDiv's default evaluator only work for float types. In order to still access the modified geometry on the CPU side, for use in modifiers or transform operators, a dedicated wrapper type is added `MESH_WRAPPER_TYPE_SUBD`. Subdivision will be lazily evaluated via `BKE_object_get_evaluated_mesh` which will create such a wrapper if possible. If the final subdivision surface is not needed on the CPU side, `BKE_object_get_evaluated_mesh_no_subsurf` should be used. Enabling or disabling GPU subdivision can be done through the user preferences (under Viewport -> Subdivision). See patch description for benchmarks.

2021-05-26	GPU: Compute Pipeline.	Jeroen Bakker
	With the compute pipeline calculation can be offloaded to the GPU. This patch only adds the framework for compute. So no changes for users at this moment. NOTE: As this is an OpenGL4.3 feature it must always have a fallback. Use `GPU_compute_shader_support` to check if compute pipeline can be used. Check `gpu_shader_compute*` test cases for usage. This patch also adds support for shader storage buffer objects and device only vertex/index buffers. An alternative that had been discussed was adding this to the `GPUBatch`, this was eventually not chosen as it would lead to more code when used as part of a shading group. The idea is that we add an `eDRWCommandType` in the near future. Reviewed By: fclem Differential Revision: https://developer.blender.org/D10913

2020-09-07	Cleanup: GLBackend: Move buf_free and tex_free to GLContext	Clément Foucault
	This makes it easier to follow. Also removes the GL related functions inside gpu_context.cc.
2020-09-06	GPUIndexBuf: GL backend Isolation	Clément Foucault
	This is part of the Vulkan backend task T68990. There is no real change, only making some code re-organisation. This also make the IndexBuf completely abstract from outside the GPU module.
