| 2017-11-11 | Cycles: Set error if a split kernel fails to load | Mai Lavelle | |
| To help catch cases where adding a new kernel is missed for one of the device implementations. | |||
| 2017-11-10 | Cycles: Fix compilation error with latest OIIO | Sergey Sharybin | |
| There was some changes about namespaces, which causes ambiguities. Replaces using namespace with an explicit symbols we need. Is good idea to NOT pull in the whole namespace anyway! | |||
| 2017-11-10 | Cycles: better distance sampling for chromatic volume extinction. | Brecht Van Lommel | |
| Previously we picked one of the RGB channels with equal probability, but this works poorly in a dense volume after many bounces. Now we take into account the throughput and single scattering albedo. This makes it a little more practical to do brute force SSS with volumes, but is still very inefficient because we do direct light sampling at every volume bounce even when inside an opaque mesh. In theory there could be a light inside the mesh so we can't automatically disable direct lighting. | |||
| 2017-11-09 | Fix T53270: crash with multiscatter GGX after recent refactoring. | Brecht Van Lommel | |
| In fact this was an existing issue when exceeding the number of available closure, but it's more common now that we set the number to 0 for shadows and emission | |||
| 2017-11-09 | Fix (harmless) valgrind warning. | Brecht Van Lommel | |
| 2017-11-09 | Cycles: avoid reallocating tile denoising memory many times during render. | Brecht Van Lommel | |
| 2017-11-09 | Cycles: Silence warning when building without OSL | Dalai Felinto | |
| 2017-11-09 | Cycles: Replace __MAX_CLOSURE__ build option with runtime integrator variable | Mai Lavelle | |
| Goal is to reduce OpenCL kernel recompilations. Currently viewport renders are still set to use 64 closures as this seems to be faster and we don't want to cause a performance regression there. Needs to be investigated. Reviewed By: brecht Differential Revision: https://developer.blender.org/D2775 | |||
| 2017-11-08 | Cycles: add bevel shader, for raytrace based rounded edges. | Brecht Van Lommel | |
| The algorithm averages normals from nearby surfaces. It uses the same sampling strategy as BSSRDFs, casting rays along the normal and two orthogonal axes, and combining the samples with MIS. The main concern here is that we are introducing raytracing inside shader evaluation, which could be quite bad for GPU performance and stack memory usage. In practice it doesn't seem so bad though. Note that using this feature can easily slow down renders 20%, and that if you care about performance then it's better to use a bevel modifier. Mainly this is useful for baking, and for cases where the mesh topology makes it difficult for the bevel modifier to work well. Differential Revision: https://developer.blender.org/D2803 | |||
| 2017-11-08 | Code refactor: rename subsurface to local traversal, for reuse. | Brecht Van Lommel | |
| 2017-11-08 | Cycles: antialias normal baking if the mesh has a bump map. | Brecht Van Lommel | |
| 2017-11-08 | Cycles: add an extra CUDA synchronize before rendering. | Brecht Van Lommel | |
| It should not be needed as far as I know, but just in case it fixes any of the recent issues like T52572. | |||
| 2017-11-08 | Fix incorrect MIS weights in Cycles with multiple lights. | Brecht Van Lommel | |
| This causes some difference in the classroom scene, where ray visibility tricks are used and break the MIS balance. Otherwise there doesn't seem to be much effect, but better to use the right formulas. Problem originally identified by Lukas. | |||

| 2017-11-05 | Cycles: reduce closure memory usage for emission/shadow shader data. | Brecht Van Lommel | |
| With a Titan Xp, reduces path trace local memory from 1092MB to 840MB. Benchmark performance was within 1% with both RX 480 and Titan Xp. Original patch was implemented by Sergey. Differential Revision: https://developer.blender.org/D2249 | |||
| 2017-11-05 | Code refactor: sum transparent and absorption weights outside closures. | Brecht Van Lommel | |

| 2017-11-05 | Cycles: reserve CUDA local memory ahead of time. | Brecht Van Lommel | |
| This way we can log the amount of memory used, and it will be important for host mapped memory support. | |||
| 2017-11-04 | Code refactor: replace CUDA array with linear memory for 1D and 2D textures. | Brecht Van Lommel | |
| This is a prequisite for getting host memory allocation to work. There appears to be no support for 3D textures using host memory. The original version of this code was written by Stefan Werner for D2056. | |||

| 2017-11-02 | Cycles: Add another limit to OpenCL memory usage | Mai Lavelle | |
| Some drivers may report very large allocation sizes, which could cause unnecessary memory usage. This is now limited to 2gb which should still be enough to get the needed performance benefits without waste. | |||

| 2017-10-31 | Experiment with adding output file meta data from render engine | Sergey Sharybin | |
| The idea is to make it possible to report extra meta data from render engine to the file writing. This way we can provide additional information such as number of samples rendered by resumable Cycles rendering so we can easily combine files back. Currently only report number of samples from Cycles when rendering a single render-layer scene. This is something what was required here at the studio. We can easily extend that further. Ideally we would also need to support non-string metadata, but that's for later.
