2021-10-14	Cycles: Kernel address space changes for MSL	Michael Jones
	This is the first of a sequence of changes to support compiling Cycles kernels as MSL (Metal Shading Language) in preparation for a Metal GPU device implementation. MSL requires that all pointer types be declared with explicit address space attributes (device, thread, etc...). There is already precedent for this with Cycles' address space macros (ccl_global, ccl_private, etc...), therefore the first step of MSL-enablement is to apply these consistently. Line-for-line this represents the largest change required to enable MSL. Applying this change first will simplify future patches as well as offering the emergent benefit of enhanced descriptiveness. The vast majority of deltas in this patch fall into one of two cases: - Ensuring ccl_private is specified for thread-local pointer types - Ensuring ccl_global is specified for device-wide pointer types Additionally, the ccl_addr_space qualifier can be removed. Prior to Cycles X, ccl_addr_space was used as a context-dependent address space qualifier, but now it is either redundant (e.g. in struct typedefs), or can be replaced by ccl_global in the case of pointer types. Associated function variants (e.g. lcg_step_float_addrspace) are also redundant. In cases where address space qualifiers are chained with "const", this patch places the address space qualifier first. The rationale for this is that the choice of address space is likely to have the greater impact on runtime performance and overall architecture. The final part of this patch is the addition of a metal/compat.h header. This is partially complete and will be extended in future patches, paving the way for the full Metal implementation.

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
2019-05-28	Fix T65212: Cycles SSS failing on 32 bit	Brecht Van Lommel

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
2018-11-09	Cycles: Cleanup, spacing after preprocessor	Sergey Sharybin
	It is supposed to be two spaces before comment stating which if else/endif statements corresponds to. Was mainly violated in the header guards.

2017-05-07	Cycles: Implement denoising option for reducing noise in the rendered image	Lukas Stockner
	This commit contains the first part of the new Cycles denoising option, which filters the resulting image using information gathered during rendering to get rid of noise while preserving visual features as well as possible. To use the option, enable it in the render layer options. The default settings fit a wide range of scenes, but the user can tweak individual settings to control the tradeoff between a noise-free image, image details, and calculation time. Note that the denoiser may still change in the future and that some features are not implemented yet. The most important missing feature is animation denoising, which uses information from multiple frames at once to produce a flicker-free and smoother result. These features will be added in the future. Finally, thanks to all the people who supported this project: - Google (through the GSoC) and Theory Studios for sponsoring the development - The authors of the papers I used for implementing the denoiser (more details on them will be included in the technical docs) - The other Cycles devs for feedback on the code, especially Sergey for mentoring the GSoC project and Brecht for the code review! - And of course the users who helped with testing, reported bugs and things that could and/or should work better!
2016-07-31	Cycles: refactor kernel closure storage to use structs per closure type.	Brecht Van Lommel
	Reviewed By: dingto, sergey Differential Revision: https://developer.blender.org/D2127
2015-04-26	Cleanup: Code style.	Thomas Dinges

2015-04-06	Cycles: Cleanup, spaces around assignment operator	Sergey Sharybin
	Did some bad spacing in recent commits, better to get rid of those so they does not confuse those who're working on sources.
2015-03-25	Fix T44123: Cycles SSS renders black in recent builds	Sergey Sharybin
	Issue was introduced in 01ee21f where i didn't notice *_setup() function only doing partial initialization, and some of parameters are expected to be initialized by callee function. This was hitting only some setups, so tests with benchmark scenes didn't unleash issues. Now it should all be fine. This is to go to the 2.74 branch and we actually might re-AHOY.
2015-03-23	Fix T43926: Volume scatter: intersecting objects GPU rendering artifacts	Sergey Sharybin
	Fix T44007: Cycles Volumetrics: block artifacts with overlapping volumes The issue was caused by uninitialized parameters of some closures, which lead to unpredictable behavior of shader_merge_closures().
2015-02-17	Cycles: Remove empty closure blur code and the corresponding entries in the ↵	Thomas Dinges
	switch. Most compilers will probably optimize that out, but I still don't see a reason to keep it.
2013-11-18	Cycles: change __device and similar qualifiers to ccl_device in kernel code.	Brecht Van Lommel
	This to avoids build conflicts with libc++ on FreeBSD, these __ prefixed values are reserved for compilers. I apologize to anyone who has patches or branches and has to go through the pain of merging this change, it may be easiest to do these same replacements in your code and then apply/merge the patch. Ref T37477.
2013-05-16	Code cleanup / Cycles:	Thomas Dinges
	* Some simplification of closure code (Velvet and Toon).
2012-12-12	Cycles: disable scaling up of ray differentials after diffuse/glossy bounce, ↵	Brecht Van Lommel
	this isn't working well for OSL texture filtering and wasn't very helpful to begin with, a better solution should be possible.
2012-10-20	Cycles OSL: most closure code is now shared between OSL and SVM. Also fix	Brecht Van Lommel
	transmission pass and filter glossy option. The BSDF closure class is now more similar to the SVM closures, and includes some flags and labels that are needed to properly categorize the BSDF's for render passes. Phong closure is gone for the moment, needs to be adapated to the new structure still.
