2017-03-23	Cycles: Use SSE-optimized version of triangle intersection for motion triangles	Sergey Sharybin
	The title says it all actually. Gives up to 10% speedup on test scenes here on i7-6800K. Render times on GPU are unreliable here, but there might be some slowdown caused by watertight nature of intersections.
2017-03-23	Cycles: Move triangle intersection precalc to an util file	Sergey Sharybin
	This is a preparation work for the followup commit which wil l move remaining parts of Woop intersection logic to an utility file. Doing it as a separate commit to keep changes more atomic and easier to bisect when/if needed.
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.
2017-01-13	Cycles: Fix wrong transparent shadows for motion blur hair	Sergey Sharybin
	This was a missing bit from b53ce9a.
2016-09-20	Cycles: Make regular bvh traversal functions close to each other	Sergey Sharybin

2016-09-19	Cycles: Cleanup, sync some comments across different traversal	Sergey Sharybin

2016-09-19	Cycles: Cleanup, always use parenthesis	Sergey Sharybin
	Makes it simpler to compare different traversal algorithms.
2016-09-14	Cycles: Also support the constant emission speedup for mesh lights	Lukas Stockner
	Reviewers: brecht, sergey, dingto, juicyfruit Differential Revision: https://developer.blender.org/D2220
2016-08-01	Cycles: Tweaks to support CUDA 8 toolkit	Sergey Sharybin
	All the changes are mainly giving explicit tips on inlining functions, so they match how inlining worked with previous toolkit. This make kernel compiled by CUDA 8 render in average with same speed as previous kernels. Some scenes are somewhat faster, some of them are somewhat slower. But slowdown is within 1% so far. On a positive side it allows us to enable newer generation cards on buildbots (so GTX 10x0 will be officially supported soon).
2016-07-26	Cycles: Revert previous fixes to intersect_all functions	Sergey Sharybin
	While they prevent legit write past the array boundary error those fixes introduced regression in behavior when having exact max_hits transparent intersections and nothing else. Previous code would have considered such case a totally opaque, but it's not correct. Fixes T48941: Some materials don't get transparent shadows anymore
2016-07-14	Cycles: Fix wrong termination criteria in intersect_all functions	Sergey Sharybin
	It was possible to miss bounces termination criteria in this functions, mainly when max_hits was set to 0. Made the check more robust in traversal functions (which should not affect performance, it's an operation of same complexity AFAIK). Also avoid doing ray-scene intersection from shadow_blocked when limit of transparent bounces was already reached.
2016-07-11	Fix T48824: Crash when having too many ray-to-volume intersections	Sergey Sharybin
	Code might have writing past the array boundaries.
2016-07-11	Cycles: Cleanup, variables name	Sergey Sharybin
	Using camel case for variables is something what didn't came from our original code, but rather from third party libraries. Let's avoid those as much as possible.
2016-07-11	Cycles: Add _all suffix to shadow traversal file	Sergey Sharybin
	Matches better naming of volume traversal files, where we've got optimized versions of a single step of volume intersection and traversal which will gather all volume intersections.
