2021-10-26	Cycles: changes to source code folders structure	Brecht Van Lommel
	* Split render/ into scene/ and session/. The scene/ folder now contains the scene and its nodes. The session/ folder contains the render session and associated data structures like drivers and render buffers. * Move top level kernel headers into new folders kernel/camera/, kernel/film/, kernel/light/, kernel/sample/, kernel/util/ * Move integrator related kernel headers into kernel/integrator/ * Move OSL shaders from kernel/shaders/ to kernel/osl/shaders/ For patches and branches, git merge and rebase should be able to detect the renames and move over code to the right file.
2021-09-21	Cycles: merge of cycles-x branch, a major update to the renderer	Brecht Van Lommel
	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

2020-06-24	Cycles: add denoising settings to the render properties	Brecht Van Lommel
	Enabling render and viewport denoising is now both done from the render properties. View layers still can individually be enabled/disabled for denoising and have their own denoising parameters. Note that the denoising engine also affects how denoising data passes are output even if no denoising happens on the render itself, to make the passes compatible with the engine. This includes internal refactoring for how denoising parameters are passed along, trying to avoid code duplication and unclear naming. Ref T76259
2020-06-22	Cleanup: minor refactoring around DeviceTask	Brecht Van Lommel

2019-09-30	Fix "denoise_animation" tests with OptiX in Cycles	Patrick Mours
	The OptiX device only loads the denoising kernels when the "use_denoising" feature is active. This was not set by the calling code however and therefore they were never loaded and attempting to launch them failed (see T69801).

2019-06-01	Cycles Denoising: Get rid of halos around bright edges	Lukas Stockner
	Previously, bright edges (e.g. caused by rim lighting) would sometimes get halos around them after denoising. This change introduces a log(1+x) highlight compression step that is performed before denoising and reversed afterwards. That way, the denoising algorithm itself operates in the compressed space and therefore bright edges cause less numerical issues.
2019-05-01	Cleanup: comments (long lines) in cycles	Campbell Barton

2019-04-17	ClangFormat: apply to source, most of intern	Campbell Barton
	Apply clang format as proposed in T53211. For details on usage and instructions for migrating branches without conflicts, see: https://wiki.blender.org/wiki/Tools/ClangFormat
2019-03-04	Fix Cycles animation denoising giving black pixels for some outliers.	Brecht Van Lommel
	The denoising code expects the output buffer to be filled with the noisy image, which was not the case for standalone denoising.
2019-02-28	Fix Cycles animation denoising not working for files on a network drive.	Brecht Van Lommel
	Can't do cross-device renaming, so put temporary file in same folder as output file.
2019-02-14	Fix Cycles build error with OpenImageIO 2.x.	Brecht Van Lommel

2019-02-13	Fix T61457, T61489, T61482: build errors and memory warning in Cycles.	Brecht Van Lommel
	For OIIO 2.x we must use unique_ptr. This also required updating the guarded allocator for std::move to work. Since C++11 construct/destroy have a default implementation that also works this case, so we just leave it out.
2019-02-11	Cycles: add animation denoising Python operator.	Lukas Stockner
	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!
