2017-01-20	Cycles: Cleanup, indentation within preprocessor	Sergey Sharybin

2017-01-20	Cycles: Implement AVX2 path for curve intersection functions	Sergey Sharybin
	Gives little performance improvement on Linux and gives up to 2% speedup on koro.blend on Windows. Inspired by Maxym Dmytrychenko, thanks!
2016-10-19	Fix Cycles CUDA performance on CUDA 8.0.	Brecht Van Lommel
	Mostly this is making inlining match CUDA 7.5 in a few performance critical places. The end result is that performance is now better than before, possibly due to less register spilling or other CUDA 8.0 compiler improvements. On benchmarks scenes, there are 3% to 35% render time reductions. Stack memory usage is reduced a little too. Reviewed By: sergey Differential Revision: https://developer.blender.org/D2269
2016-08-06	Cycles: Add AttributeDescriptor	Mai Lavelle
	Adds a descriptor for attributes that can easily be passed around and extended to contain more data. Will be used for attributes on subdivision meshes. Reviewed By: brecht Differential Revision: https://developer.blender.org/D2110
2016-07-02	Cleanup: comment blocks	Campbell Barton

2016-03-25	Cycles: Cleanup, indent nested preprocessor directives	Sergey Sharybin
	Quite straightforward, main trick is happening in path_source_replace_includes(). Reviewers: brecht, dingto, lukasstockner97, juicyfruit Differential Revision: https://developer.blender.org/D1794
2015-05-14	Cycles: Enable hair for split kernels when using Intel or NVidia drivers	Sergey Sharybin
	Apart from simply enabling this features needed changes to the code were done. Technical change, replacing SD access from "simple" structure to SOA.
2015-04-27	Cycles: Use native saturate function for CUDA	Sergey Sharybin
	This more a workaround for CUDA optimizer which can't optimize clamp(x, 0, 1) into a single instruction and uses 4 instructions instead. Original patch by @lockal with own modification: Don't make changes outside of the kernel. They don't make any difference anyway and term saturate() has a bit different meaning outside of kernel. This gives around 2% of speedup in Barcelona file, but in more complex shader setups with lots of math nodes with clamping speedup could be much nicer.

2015-03-27	Cycles: Code cleanup, spaces around keywords	Sergey Sharybin
	This inconsistency drove me totally crazy, it's really confusing when it's inconsistent especially when you work on both Cycles and Blender sides. Shouldn;t cause merge PITA, it's whitespace changes only, Git should be able to merge it nicely.
2015-03-07	Fix T41066: An actual fix for curve intersection on FMA-enabled CPUs	Sv. Lockal

2015-01-16	Cycles: Cleanup and optimization comment update	Sergey Sharybin

2014-10-11	Cycles: set hit values in-order	Campbell Barton

2014-07-27	Fix T41139: Cycles Hair BSDF roughness problem	Sergey Sharybin

2014-06-13	Cycles Refactor: Add SSE Utility code from Embree for cleaner SSE code.	Thomas Dinges
	This makes the code a bit easier to understand, and might come in handy if we want to reuse more Embree code. Differential Revision: https://developer.blender.org/D482 Code by Brecht, with fixes by Lockal, Sergey and myself.
2014-06-01	Code cleanup, unused variables and comments.	Thomas Dinges

2014-05-09	Fix cycles motion pass for hair curves showing a bit of motion when there ↵	Brecht Van Lommel

2014-05-03	Code cleanup: Add -Werror=float-conversion to Cycles	Campbell Barton

2014-04-27	Code cleanup: style, unused import	Campbell Barton

2014-04-23	Cycles: some tiny hair intersection optimizations that help maybe 2%.	Brecht Van Lommel

2014-04-23	Fix occasional wrong normal for curves with minimum width.	Brecht Van Lommel
	This caused a couple of fireflies in koro_final.blend. The wrong normal would cause the shading point to be set as backfacing, which triggered another bug with hair BSDFs on the backface of hair curves. That one is not fixed yet but there's a comment in the code about it now.
2014-04-03	Cycles: avoid 1.0f/(1.0f/x) divisions, which msvc (only) can't optimize.	Sv. Lockal
	This makes bmw scene in msvc 12 builds 6% faster. It also gives a minor speedup for SSE hair in all compilers.
