2017-02-05OpenGL: use GL4 on Linux when availableMike Erwin
Minimum target is still 3.3 On AMD pro driver, asking for a 3.3 context gives us *exactly* 3.3, not 3.3+ as desired. Have not tested proprietary NV or Intel drivers, but this fix should work on all vendors.

2017-01-27Cycles: Add option to replace GI with AO approximation after certain amount ↵Sergey Sharybin
of bounces This is a speed up option which is mainly useful for viewport. Gives nice speedup in the barbershop scene of 2x when replacing GI with AO after 2nd bounce without loosing too much details.

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

2017-01-25Fix T49405: Crash when baking with adaptive subdivisionMai 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.

2017-01-23Cycles: Split ShaderData object and shader flagsSergey 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).

2017-01-22Fix 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).

2017-01-20Cycles: Cleanup, split one gigantic function into two smaller onesSergey Sharybin
2017-01-20Cycles: Store time in BVH nodesSergey 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.
2017-01-20Cycles: Add option to split triangle motion primitives by time stepsSergey 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.
2017-01-20Cycles: Add option to split curve motion primitives by time stepsSergey 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.
2017-01-20Cycles: Add utility function to calculate curve boundbox from given 4 keysSergey 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.

2017-01-20Cycles: Move motion triangle intersection functions to own fileSergey 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.

2017-01-19Cycles: Don't use fast math for the host codeSergey 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.

Currently unused, but might become really handy in the future.
2017-01-19Cycles: Remove using namespace hellSergey 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.
