2017-01-25	[Cycles/MSVC/Testing] Fix broken test code.	lazydodo
	Currently the tests don't run on windows for the following reasons 1) render_graph_finalize has an linking issue due missing a bunch of libraries (not sure why this is not an issue for linux) 2) This one is more interesting, in test/python/cmakelists.txt ${TEST_BLENDER_EXE_BARE} and ${TEST_BLENDER_EXE} are flat out wrong, but for some reason this doesn't matter for most tests, cause ctest will actually go out and look for the executable and fix the path for you BUT only for the command, if you use them in any of the parameters it'll happily pass on the wrong path. 3) on linux you can just run a .py file, windows is not as awesome and needs to be told to run it with pyton. 4) had to use the NAME/COMMAND long form of add_test otherwise $<TARGET_FILE:blender> doesn't get expanded, why? beats me. 5) missing idiff.exe for msvc2015/x64 in the libs folder. This patch addresses 1-4 , but given I have no working Linux build environment, I'm unsure if it'll break anything there 5 has been fixed in rBL61751 Reviewers: juicyfruit, brecht, sergey Reviewed By: sergey Subscribers: Blendify Tags: #cycles, #automated_testing Differential Revision: https://developer.blender.org/D2367

2017-01-25	Fix T49405: Crash when baking with adaptive subdivision	Mai Lavelle
	Blenders baking system currently doesn't support the topology used by adaptive subdivision and primitive ids will be wrong or out of range leading to crashes. Updating the baking system to support other topologies would be a bit involved, so for now we simply disable subdivision while baking to avoid crashes.

2017-01-23	Cycles: Split ShaderData object and shader flags	Sergey Sharybin
	We started to run out of bits there, so now we separate flags which came from __object_flags and which are either runtime or coming from __shader_flags. Rule now is: SD_OBJECT_* flags are to be tested against new object_flags field of ShaderData, all the rest flags are to be tested against flags field of ShaderData. There should be no user-visible changes, and time difference should be minimal. In fact, from tests here can only see hardly measurable difference and sometimes the new code is somewhat faster (all within a noise floor, so hard to tell for sure).

2017-01-23	Cycles: Make object flag names more obvious that hey are object and not shader	Sergey Sharybin

2017-01-23	Cycles: Fix typo in the panel name	Sergey Sharybin
	No user visible changes, it was a typo in the name of the class. Spotted by povmaniac in IRC, thanks!
2017-01-23	Cycles: Update current Cycles version	Sergey Sharybin

2017-01-22	Fix T50491: Cycles UI breaks when pushing F8.	Bastien Montagne
	Cycles add-on did not actually support reloading correctly. When you want to correctly reload sub-modules (i.e. modules of an add-on which is a package), you need to use importlib, a mere import will do nothing with already loaded modules (RNA classes are sort of pre-registered when they are evaluated, through the meta-class system).
2017-01-20	Cycles: Use more const qualifiers to avoid possible issues	Sergey Sharybin

2017-01-20	Cycles: Cleanup, split one gigantic function into two smaller ones	Sergey Sharybin

2017-01-20	Cycles: Store time in BVH nodes	Sergey Sharybin
	This way we can stop traversing BVH node early on. Gives about 2-2.5x times render time improvement with 3 BVH steps. Hopefully this gives no measurable performance loss for scenes with single BVH step. Traversal is currently only implemented for QBVH, meaning old CPUs and GPU do not benefit from this change.
2017-01-20	Cycles: Add option to split triangle motion primitives by time steps	Sergey Sharybin
	Similar to the previous commit, the statistics goes as: BVH Steps Render time (sec) Memory usage (MB) 0 46 260 1 27 373 2 18 598 3 15 826 Scene used for the tests is the agent's body from one of the barber shop scenes (no textures or anything, just a diffuse material). Once again this is limited to regular (non-spatial split) BVH, Support of spatial split to this feature will come later.
2017-01-20	Cycles: Add option to split curve motion primitives by time steps	Sergey Sharybin
	The idea is to create several smaller BVH nodes for each of the motion curve primitives. This acts as a forced spatial split for the single primitive. This gives up render time speedup of motion blurred hair in the cost of extra memory usage. The numbers goes as: BVH Steps Render time (sec) Memory usage (MB) 0 258 191 1 123 278 2 69 453 3 43 627 Scene used for the tests is the agent's hair from one of the barber shop scenes. Currently it's only limited to scenes without spatial split enabled, since the spatial split builder requires some changes to work properly with motion steps coordinates.
2017-01-20	Cycles: Add utility function to calculate curve boundbox from given 4 keys	Sergey Sharybin
	Also fixed some issues with motion keys calculation: - Clamp lower and upper limits of curves so we can safely call those functions for the very first and very last curve segment. - Fixed wrong indexing for the curve radius array. - Fixed wrong motion attribute offset calculation.

2017-01-20	Cycles: Move motion triangle intersection functions to own file	Sergey Sharybin
	Mimics how regular triangles are working and makes it more clear where the stuff is located in the kernel. Needed to have some forward declarations because of the current placement of things in the kernel.

2017-01-19	Cycles: Don't use fast math for the host code	Sergey Sharybin
	This is important for the reliable behavior or isnan/isfinite/min/max functions to work with nan and non-finite values. Some of the issues with fast math are possible to work around, but didn't find a way to have reliable min/max implementation yet.
2017-01-19	Cycles: Add fast-math safe isnan and isfinite	Sergey Sharybin
	Currently unused, but might become really handy in the future.
2017-01-19	Cycles: Remove using namespace hell	Sergey Sharybin
	Please NEVER EVER use such a statement, it's only causing HUGE issues. What is even worse: it's not always possible to immediately see that the hell is coming from such a statement. There is still some statements in the existing code, will leave those for a later cleanup.

	Run into some nasty bugs while trying various things here. Wouldn't mind enabling -Wshadow for Cycles actually..
2017-01-12	Cycles: Allow up to 4 motion curve primitives per BVH node	Sergey Sharybin
	This avoids intersection AABB of different curve primitives which makes it less ray-to-primitive intersections. This gives about 30% speedup of hair rendering in the barber shop scenes here. There is still some work to be done on those files to solve major speed issues on certain frames.

2017-01-12	Cycles: Use separate limit for motion primitives for BVH node limits	Sergey Sharybin
	This way we can have different limits for regular and motion curves which we'll do in one of the upcoming commits in order to gain some percents of speedup. The reasoning here is that motion curves are usually intersecting lots of others bounding boxes, which makes it inefficient to have single primitive in the leaf node.
2017-01-12	Cycles: Change confusing logic of max leaf size check	Sergey Sharybin
	Maximal number of elements is supposed to be inclusive. That is what it was always meant in this file and what @brecht considered still the case in 6974b69c6172. In fact, the commit message to that change mentions that we allowed up to 2 curve primitives per leaf while in fact it was doing up to 1 curve primitive. Making it real 2 primitives at a max gives about 5% slowdown for the koro.blend scene. This is a reason why BVHParams.max_curve_leaf_size was changed to 1 by this change.
2017-01-12	Cycles: Cleanup, space prior to semicolon	Sergey Sharybin
	We don't have that in Blender style, no reason to violate it here.
2017-01-12	Cycles: Cleanup, make curve functions private	Sergey Sharybin
	Not only they don't really follow naming convention (we don't use camel case) but also was not necessary to keep them in the global symbol table.
2017-01-12	Cycles: Make it more clear message why curve motion attribute was removed	Sergey Sharybin

2017-01-12	Cycles: Use dedicated debug passes for traversed nodes and intersection tests	Sergey Sharybin
	This way it's more clear whether some issue is caused by lots of geometry in the node or by lots of "transparent" BVH nodes.
