2021-09-21	Cycles: merge of cycles-x branch, a major update to the renderer	Brecht Van Lommel
	This includes much improved GPU rendering performance, viewport interactivity, new shadow catcher, revamped sampling settings, subsurface scattering anisotropy, new GPU volume sampling, improved PMJ sampling pattern, and more. Some features have also been removed or changed, breaking backwards compatibility. Including the removal of the OpenCL backend, for which alternatives are under development. Release notes and code docs: https://wiki.blender.org/wiki/Reference/Release_Notes/3.0/Cycles https://wiki.blender.org/wiki/Source/Render/Cycles Credits: * Sergey Sharybin * Brecht Van Lommel * Patrick Mours (OptiX backend) * Christophe Hery (subsurface scattering anisotropy) * William Leeson (PMJ sampling pattern) * Alaska (various fixes and tweaks) * Thomas Dinges (various fixes) For the full commit history, see the cycles-x branch. This squashes together all the changes since intermediate changes would often fail building or tests. Ref T87839, T87837, T87836 Fixes T90734, T89353, T80267, T80267, T77185, T69800
2020-03-06	Cleanup: tweak Cycles #includes in preparation for clang-format sorting	Brecht Van Lommel

2019-04-17	ClangFormat: apply to source, most of intern	Campbell Barton
	Apply clang format as proposed in T53211. For details on usage and instructions for migrating branches without conflicts, see: https://wiki.blender.org/wiki/Tools/ClangFormat
2018-11-09	Cycles: Cleanup, space after (void)	Sergey Sharybin
	It was used in like 95% of places.
2017-11-16	Cycles: Fix crash with split branched path tracing	Mai Lavelle
	ShaderData memory was getting clobbered in the branched path code paths. Was caused by 087331c495b04ebd37903c0dc0e46262354cf026
2017-11-09	Cycles: Replace __MAX_CLOSURE__ build option with runtime integrator variable	Mai Lavelle
	Goal is to reduce OpenCL kernel recompilations. Currently viewport renders are still set to use 64 closures as this seems to be faster and we don't want to cause a performance regression there. Needs to be investigated. Reviewed By: brecht Differential Revision: https://developer.blender.org/D2775

2017-03-29	Cycles: Make all #include statements relative to cycles source directory	Sergey Sharybin
	The idea is to make include statements more explicit and obvious where the file is coming from, additionally reducing chance of wrong header being picked up. For example, it was not obvious whether bvh.h was refferring to builder or traversal, whenter node.h is a generic graph node or a shader node and cases like that. Surely this might look obvious for the active developers, but after some time of not touching the code it becomes less obvious where file is coming from. This was briefly mentioned in T50824 and seems @brecht is fine with such explicitness, but need to agree with all active developers before committing this. Please note that this patch is lacking changes related on GPU/OpenCL support. This will be solved if/when we all agree this is a good idea to move forward.

2017-03-11	Fix T50888: Numeric overflow in split kernel state buffer size calculation	Mai Lavelle
	Overflow led to the state buffer being too small and the split kernel to get stuck doing nothing forever.
2017-03-09	Cycles: SSS and Volume rendering in split kernel	Hristo Gueorguiev
	Decoupled ray marching is not supported yet. Transparent shadows are always enabled for volume rendering. Changes in kernel/bvh and kernel/geom are from Sergey. This simiplifies code significantly, and prepares it for record-all transparent shadow function in split kernel.

2017-03-08	Cycles: Calculate size of split state buffer kernel side	Mai Lavelle
	By calculating the size of the state buffer in the kernel rather than the host less code is needed and the size actually reflects the requested features. Will also be a little faster in some cases because of larger global work size.
2017-03-08	Cycles: Remove sum_all_radiance kernel	Mai Lavelle
	This was only needed for the previous implementation of parallel samples. As we don't have that any more it can be removed. Real reason for removal tho is this: `per_sample_output_buffers` was being calculated too small and artifacts resulted. The tile buffer is already the correct size and calculating the size for `per_sample_output_buffers` is a bit difficult with the current layout of the code. As `per_sample_output_buffers` was only needed for `sum_all_radiance`, removing that kernel and writing output to the tile buffer directly fixes the artifacts.
2017-03-08	Cycles: CUDA implementation of split kernel	Mai Lavelle

2017-03-08	Cycles: OpenCL split kernel refactor	Mai Lavelle
	This does a few things at once: - Refactors host side split kernel logic into a new device agnostic class `DeviceSplitKernel`. - Removes tile splitting, a new work pool implementation takes its place and allows as many threads as will fit in memory regardless of tile size, which can give performance gains. - Refactors split state buffers into one buffer, as well as reduces the number of arguments passed to kernels. Means there's less code to deal with overall. - Moves kernel logic out of OpenCL kernel files so they can later be used by other device types. - Replaced OpenCL specific APIs with new generic versions - Tiles can now be seen updating during rendering
