| 2018-05-24 | Cycles Denoising: Don't use atomics in the accumulation kernel on CPUs | Lukas Stockner | |
| The GPU kernel needs to use atomics for accumulation since all offsets are processed in parallel, but on CPUs that's not the case, so we can disable them there for a considerable speedup. | |||
| 2018-05-24 | Cycles/Compositor: Add arctan2 operation to the Math node | Lukas Stockner | |
| The Math node currently has the normal atan() function, but for actual angles this is fairly useless without additional nodes to handle the signs. Since the node has two inputs anyways, it only makes sense to add an arctan2 option. Reviewers: sergey, brecht Differential Revision: https://developer.blender.org/D3430 | |||

| 2018-03-29 | Fix T54455: OpenCL build error after recent changes. | Brecht Van Lommel | |
| 2018-03-29 | Cycles: take into account diffuse roughness for roughness baking. | Matt Heimlich | |
| Roughness baking previously defaulted to 1.0 for all diffuse materials, now we also bake roughness values of Oren-Nayer and Principled Diffuse. Differential Revision: https://developer.blender.org/D3115 | |||
| 2018-03-28 | Cycles: don't require pthreads as dependency on Windows. | Jeff Witthuhn | |
| Use C++11 threads when available, and native critical section on Windows. Later on we can remove pthread code when C+11 becomes required. Differential Revision: https://developer.blender.org/D3116 | |||
| 2018-03-28 | Cycles: Fix bad register cast in sseb | Sergey Sharybin | |
| This is currently unused code, but causes gcc-8 to fail. | |||
| 2018-03-27 | Fix T54420: too much volume render noise with multiple volume objects. | Brecht Van Lommel | |
| Random numbers for step offset were correlated, now use stratified samples which reduces noise as well for some types of volumes, mainly procedural ones where the step size is bigger than the volume features. | |||
| 2018-03-23 | Glog/gflags: Reduce amount of local modifications | Sergey Sharybin | |
| With better directory layout and more proper include statements we can avoid several local modifications, such as changing config.h for Windows Glog and the ones related on pass-through statements in logging headers in Glog. This commit also makes unused functions not-a-warning for external code. | |||
| 2018-03-20 | Fix build error on Windows 32 bit. | Brecht Van Lommel | |
| 2018-03-19 | Fix T54317: overlapping volume render bug after recent changes. | Brecht Van Lommel | |
| Increasing the samplig dimensions like this is not optimal, I'm looking into some deeper changes to reuse the random number and change the RR probabilities, but this should fix the bug for now. | |||
| 2018-03-19 | Fix T54356: volume rendering bug using just color attribute. | Brecht Van Lommel | |
| 2018-03-16 | Code refactor: move OIIO image buffer writing outside session, into callback. | Guillaume Chereau | |

| changes. | |||
| 2018-03-12 | Cycles: add constant folding to displacement nodes. | Brecht Van Lommel | |
| 2018-03-10 | Cycles: add roughness baking support, using squared roughness convention. | Brecht Van Lommel | |
| 2018-03-10 | Cycles: switch to squared roughness convention for all nodes. | Brecht Van Lommel | |
| This was already done for the Principled BSDF to be compatible with typical baked roughness maps in PBR workflows. | |||
| 2018-03-10 | Code cleanup: fix compiler warning. | Brecht Van Lommel | |
| 2018-03-10 | Fix T54279: viewport update bug with volume meshes. | Brecht Van Lommel | |
| Meshes without vertex normals were not handled correctly. | |||
| 2018-03-10 | Code refactor: reduce number of loops over meshes. | Brecht Van Lommel | |
| 2018-03-10 | Fix T54278: volume artifacts with small density and color after recent changes. | Brecht Van Lommel | |
| 2018-03-10 | Code cleanup: use spaces for aligned indentation. | Brecht Van Lommel | |
| 2018-03-10 | Cycles: support arbitrary number of motion blur steps for objects. | Brecht Van Lommel | |
| 2018-03-10 | Cycles: support arbitrary number of motion blur steps for cameras. | Brecht Van Lommel | |
| 2018-03-10 | Code refactor: motion blur cleanups, preparing for next commit. | Brecht Van Lommel | |
| 2018-03-10 | Code refactor: don't expose UpdateObjectTransformState in header. | Brecht Van Lommel | |
| 2018-03-10 | Code refactor: make Transform always affine, dropping last row. | Brecht Van Lommel | |
| This save a little memory and copying in the kernel by storing only a 4x3 matrix instead of a 4x4 matrix. We already did this in a few places, and those don't need to be special exceptions anymore now. | |||
| 2018-03-10 | Code refactor: add DecomposedTransform. | Brecht Van Lommel | |
| This is in preparation of making Transform affine only, and also gives us a little extra type safety so we don't accidentally treat it as a regular 4x4 matrix. | |||
| 2018-03-10 | Code refactor: add ProjectionTransform separate from regular Transform. | Brecht Van Lommel | |
| This is in preparation of making Transform affine only. | |||
| 2018-03-10 | Code refactor: avoid motion transform copy, remove unused curved code. | Brecht Van Lommel | |
| The purpose of the previous code refactoring is to make the code more readable, but combined with this change benchmarks also render about 2-3% faster with an NVIDIA Titan Xp. | |||
| 2018-03-10 | Code refactor: use KernelShader and KernelParticle instead of float arrays. | Stefan Werner | |
| Original patch by Stefan with modifications by Brecht. | |||

| 2018-03-03 | Fix T54202: Cycles crash rendering empty mesh volume after recent optimization. | Brecht Van Lommel | |
| 2018-03-02 | Fix Cycle standalone build. | Brecht Van Lommel | |
| 2018-03-02 | Cycles: Fix building of OpenCL kernels after volume optimization commit | Mai Lavelle | |
| OpenCL is C based, so no support for operators. Related commit: 7377d411b47d50cd943cd | |||
| 2018-03-01 | Cycles volume: fast empty space optimization by generating a tight mesh | Kévin Dietrich | |
| around the volume. We generate a tight mesh around the active voxels of the volume in order to effectively skip empty space, and start volume ray marching as close to interesting volume data as possible. See code comments for details on how the mesh generation algorithm works. This gives up to 2x speedups in some scenes.

| 2018-03-01 | Cycles: don't count volume boundaries as transparent bounces. | Brecht Van Lommel | |
| This is more important now that we will have tigther volume bounds that we hit multiple times. It also avoids some noise due to RR previously affecting these surfaces, which shouldn't have been the case and should eventually be fixed for transparent BSDFs as well. For non-volume scenes I found no performance impact on NVIDIA or AMD. For volume scenes the noise decrease and fixed artifacts are worth the little extra render time, when there is any. | |||
| 2018-02-28 | Cycles: principled absorption color now has more effect at lower values. | Brecht Van Lommel | |
| 2018-02-28 | Code cleanup: refactor Cycles image metadata retrieval to use a struct. | Brecht Van Lommel | |
| 2018-02-23 | Cycles: add Principled Volume shader. | Brecht Van Lommel | |
| Similar to the Principled BSDF, this should make it easier to set up volume materials. Smoke and fire can be rendererd with just a single principled volume node, the appropriate attributes will be used when available. The node also works for simpler homogeneous volumes like water or mist. Differential Revision: https://developer.blender.org/D3033 | |||
| 2018-02-23 | Cycles: change smoke color grid to not include density multiplied in. | Brecht Van Lommel | |
| This breaks backwards compatibility some, making smoke colors brighters than before. But it is also more correct this way. | |||
