2017-02-27	Cycles: Experiment with replacing Sharp Glossy with GGX when Filter Glossy ↵	Sergey Sharybin
	is used The idea is to make it simpler to remove noise from scenes when some prop uses Sharp glossy closure and causes noise in certain cases. Previously Sharp Glossy was not affected by Filter Glossy at all, which was quite confusing. Here is a file which demonstrates the issue: {F417797} After applying the patch all the noise from the scene is gone. This change also solves fireflies reported in T50700.

2017-02-22	Cycles: Fix shading with autosmooth and custom normals	Sergey Sharybin
	New logic of split_faces was leaving mesh in a proper state from Blender's point of view, but Cycles wanted loop normals to be "flushed" to vertex normals. Now we do such a flush from Cycles side again, so we don't leave bad meshes behind. Thanks Bastien for assistance here!
2017-02-22	Cycles: Additionally report all OpenCL cflags	Sergey Sharybin
	This way we can control exact spaces and such added to the cflags which is crucial to troubleshoot certain drivers.
2017-02-21	Cycles: Speedup by avoiding extra calculations in noise texture when unneeded	Mai Lavelle
	Noise texture is now faster when the color socket is unused. Potential for speedup spotted by @nutel.

2017-02-20	Fix T50718: Regression: Split Normals Render Problem with Cycles	Sergey Sharybin
	The issue seems to be caused by vertex normal being re-calculated to something else than loop normal, which also caused wrong loop normals after re-calculation. For now issue is solved by preserving CD_NORMAL for loops after split_faces() is finished, so render engine can access original proper value.

2017-02-16	Faces split: Don't leave CD_NORMAL after split	Sergey Sharybin
	This is supposed to be a temporary layer. If someone needs loop normals after split it should explicitly ask for that.

2017-02-15	Cycles: Fix CUDA compilation error after recent changes	Sergey Sharybin

2017-02-15	Cycles: Don't calculate primitive time if BVH motion steps are not used	Sergey Sharybin
	Solves memory regression by the default configuration.
2017-02-15	Cycles: Pass special flag whether BVH motion steps are used	Sergey Sharybin
	Doesn't currently change anything, but would need for some future work here. It uses existing padding in kernel BVH structure, so there is nothing changed memory-wise.
2017-02-15	Cycles: Fix wrong hair render results when using BVH motion steps	Sergey Sharybin
	The issue here was mainly coming from minimal pixel width feature which is quite commonly enabled in production shots. This feature will use some probabilistic heuristic in the curve intersection function to check whether we need to return intersection or not. This probability is calculated for every intersection check. Now, when we use multiple BVH nodes for curve primitives we increase probability of that primitive to be considered a good intersection for us. This is similar to increasing minimal width of curve. What is worst here is that change in the intersection probability fully depends on exact layout of BVH, meaning probability might change differently depending on a view angle, the way how builder binned the primitives and such. This makes it impossible to do simple check like dividing probability by number of BVH steps. Other solution might have been to split BVH into fully independent trees, but that will increase memory usage of all the static objects in the scenes, which is also not something desirable. For now used most simple but robust approach: store BVH primitives time and test it in curve intersection functions. This solves the regression, but has two downsides: - Uses more memory. which isn't surprising, and ANY solution to this problem will use more memory. What we still have to do is to avoid this memory increase for cases when we don't use BVH motion steps. - Reduces number of maximum available textures on pre-kepler cards. There is not much we can do here, hardware gets old but we need to move forward on more modern hardware..
2017-02-15	Cycles: Fix missing initialization of triangle BVH steps	Sergey Sharybin
	Likely was harmless for Blender, but better be safe here.
2017-02-15	Cycles: Fix wrong pointiness caused by precision issues	Sergey Sharybin

2017-02-13	Cycles: Optimize sorting of transparent intersections on CUDA	Sergey Sharybin

2017-02-13	Cycles: Fix wrong transparent shadows with CUDA	Sergey Sharybin
	Was a bug in recent optimization commit.
2017-02-13	Cycles: Fix wrong shading on GPU when background has NaN pixels and MIS enabled	Sergey Sharybin
	Quite simple fix for now which only deals with this case. Maybe we want to do some "clipping" on image load time so regular textures wouldn't give NaN as well.
2017-02-13	Cycles: Use fast math without finite optimization	Sergey Sharybin
	This allows us to use faster math and still have reliable isnan/isfinite tests. Only do it for host side, kernels stays unchanged. Thanks Lukas Stockner for the tip!
2017-02-13	Fix T50655: Pointiness is too slow to calculate	Sergey Sharybin
	Optimize vertex de-duplication the same way as we do doe Remove Doubles.
2017-02-13	Cycles: Use Cycles-side mesh instead of C++ RNA	Sergey Sharybin
	Those are now matching and it's faster to skip C++ RNA to calculate pointiness.
2017-02-12	Cycles: Don't use built-in API for image sequences in preview mode	Sergey Sharybin
	Our Python API is not ready for such things at all. Better be slower but more correct for until we improve our API.
2017-02-10	Cycles: Cleanup, move EdgeMap to blender_util	Sergey Sharybin
	it's better place for such an utility structure. Still not fully ideal tho.

	Simplifies some logic.
2017-02-10	Cycles: Fix pointiness attribute giving wrong results with autosplit	Sergey Sharybin

2017-02-08	Cycles: Split shadow functions to avoid some duplicated calculations	Sergey Sharybin

2017-02-08	Cycles: Store shadow intersections in the kernel globals	Sergey Sharybin
	Seems CUDA failed to de-duplicate the array across multiple inlined versions of the shadow_blocked(). Helped it a bit with that now. Gives about 100MB memory improvement on a scenes after previous commit and brings up memory "regression" to only 100MB comparing to the master branch now.
2017-02-08	Cycles: Speedup transparent shadows on CUDA	Sergey Sharybin
	This commit enables record-all behavior of transparent shadows rays. Render times difference goes as following: GTX 1080 render time BMW -0.5% Fishy Cat -0.0% Pabellon Barcelona -11.6% Classroom +1.2% Koro -58.6% Kernel will now use some extra VRAM memory to store the intersection array (200MB on my configuration). This we can optimize out with some further commits.
2017-02-08	Cycles: Implement record-all transparent shadow function for GPU	Sergey Sharybin
	The idea is to record all possible transparent intersections when shooting transparent ray on GPU (similar to what we were doing on CPU already). This avoids need of doing whole ray-to-scene intersections queries for each intersection and speeds up a lot cases like transparent hair in the cost of extra memory. This commit is a base ground for now and this feature is kept disabled for until some further tweaks.
