Cycles: remove prefix from source code file names Remove prefix of filenames that is the same as the folder name. This used to help when #includes were using individual files, but now they are always relative to the cycles root directory and so the prefixes are redundant. For patches and branches, git merge and rebase should be able to detect the renames and move over code to the right file.

Cycles: add animation denoising Python operator. This adds a cycles.denoise_animation operator, which denoises an animation sequence or individual file. Renders must be saved as multilayer EXR files with denoising data passes. By default file path and frame range come from the current scene, and EXR files are denoised in-place. Alternatively, a different input and/or output file path can be provided. Denoising settings come from the current view layer. Renders can be denoised again with different settings, as the original noisy image is preserved along with other passes and metadata. There is no user interface yet for this feature, that comes later. Code by Lukas with modifications by Brecht. This feature was originally developed for Tangent Animation, thanks for the support!

Cycles: some warning fixes, cpu device task tweaks, avoid unnecessary tonemap in non-viewport render, and some utility functions.

int system_cpu_bits();
Fix cycles intersection issue with overlapping faces on windows 32 bit and CPU without SSE3 support, due to 80 bit precision float register being used for one bounding box but not the one next to it.

Cycles: test code for sse 4.1 kernel and alignment for some vector types. This is mostly work towards enabling the __KERNEL_SSE__ option to start using SIMD operations for vector math operations. This 4.1 kernel performes about 8% faster with that option but overall is still slower than without the option. WITH_CYCLES_OPTIMIZED_KERNEL_SSE41 is the cmake flag for testing this kernel. Alignment of int3, int4, float3, float4 to 16 bytes seems to give a slight 1-2% speedup on tested systems with the current kernel already, so is enabled now.

Cycles: Add an AVX kernel for CPU rendering. * AVX is available on Intel Sandy Bridge and newer and AMD Bulldozer and newer. * We don't use dedicated AVX intrinsics yet, but gcc auto vectorization gives a 3% performance improvement for Caminandes. Tested on an i5-3570, Linux x64. * No change for Windows yet, MSVC 2008 does not support AVX. Reviewed by: brecht Differential Revision: https://developer.blender.org/D216

bool system_cpu_support_avx();
Cycles: Add an AVX2 CPU kernel. This kernel is compiled with AVX2, FMA3, and BMI compiler flags. At the moment only Intel Haswell benefits from this, but future AMD CPUs will have these instructions as well. Makes rendering on Haswell CPUs a few percent faster, only benchmarked with clang on OS X though. Part of my GSoC 2014.

Cycles: CUDA support for rendering scenes that don't fit on GPU. In that case it can now fall back to CPU memory, at the cost of reduced performance. For scenes that fit in GPU memory, this commit should not cause any noticeable slowdowns. We don't use all physical system RAM, since that can cause OS instability. We leave at least half of system RAM or 4GB to other software, whichever is smaller. For image textures in host memory, performance was maybe 20-30% slower in our tests (although this is highly hardware and scene dependent). Once other type of data doesn't fit on the GPU, performance can be e.g. 10x slower, and at that point it's probably better to just render on the CPU.

Cycles: Support multithreaded compilation of kernels This patch implements a workaround to get the multithreaded compilation from D2231 working. So far, it only works for Blender, not for Cycles Standalone. Also, I have only tested the Linux codepath in the helper function. Depends on D2231.

Cycles: merge of cycles-x branch, a major update to the renderer This includes much improved GPU rendering performance, viewport interactivity, new shadow catcher, revamped sampling settings, subsurface scattering anisotropy, new GPU volume sampling, improved PMJ sampling pattern, and more. Some features have also been removed or changed, breaking backwards compatibility. Including the removal of the OpenCL backend, for which alternatives are under development. Release notes and code docs: https://wiki.blender.org/wiki/Reference/Release_Notes/3.0/Cycles https://wiki.blender.org/wiki/Source/Render/Cycles Credits: * Sergey Sharybin * Brecht Van Lommel * Patrick Mours (OptiX backend) * Christophe Hery (subsurface scattering anisotropy) * William Leeson (PMJ sampling pattern) * Alaska (various fixes and tweaks) * Thomas Dinges (various fixes) For the full commit history, see the cycles-x branch. This squashes together all the changes since intermediate changes would often fail building or tests. Ref T87839, T87837, T87836 Fixes T90734, T89353, T80267, T80267, T77185, T69800
