2022-05-04	Nodes: Add general Combine/Separate Color nodes	Hallam Roberts
	Inspired by D12936 and D12929, this patch adds general purpose "Combine Color" and "Separate Color" nodes to Geometry, Compositor, Shader and Texture nodes. - Within Geometry Nodes, it replaces the existing "Combine RGB" and "Separate RGB" nodes. - Within Compositor Nodes, it replaces the existing "Combine RGBA/HSVA/YCbCrA/YUVA" and "Separate RGBA/HSVA/YCbCrA/YUVA" nodes. - Within Texture Nodes, it replaces the existing "Combine RGBA" and "Separate RGBA" nodes. - Within Shader Nodes, it replaces the existing "Combine RGB/HSV" and "Separate RGB/HSV" nodes. Python addons have not been updated to the new nodes yet. New shader code In node_color.h, color.h and gpu_shader_material_color_util.glsl, missing methods hsl_to_rgb and rgb_to_hsl are added by directly converting existing C code. They always produce the same result. Old code As requested by T96219, old nodes still exist but are not displayed in the add menu. This means Python scripts can still create them as usual. Otherwise, versioning replaces the old nodes with the new nodes when opening .blend files. Differential Revision: https://developer.blender.org/D14034

2022-03-07	Shader Nodes: add Alpha output to Object Info node	Ethan-Hall
	An alpha component can be specified for an object's color. This adds an alpha socket to the object info shader node allowing for the alpha component of the object's color to be accessed in the shader editor. Differential Revision: https://developer.blender.org/D14141
2022-02-11	Cycles: use SPDX license headers	Brecht Van Lommel
	* Replace license text in headers with SPDX identifiers. * Remove specific license info from outdated readme.txt, instead leave details to the source files. * Add list of SPDX license identifiers used, and corresponding license texts. * Update copyright dates while we're at it. Ref D14069, T95597
2022-02-11	File headers: SPDX License migration	Campbell Barton
	Use a shorter/simpler license convention, stops the header taking so much space. Follow the SPDX license specification: https://spdx.org/licenses - C/C++/objc/objc++ - Python - Shell Scripts - CMake, GNUmakefile While most of the source tree has been included - `./extern/` was left out. - `./intern/cycles` & `./intern/atomic` are also excluded because they use different header conventions. doc/license/SPDX-license-identifiers.txt has been added to list SPDX all used identifiers. See P2788 for the script that automated these edits. Reviewed By: brecht, mont29, sergey Ref D14069
2022-01-25	Cycles: add Point Info node	Brecht Van Lommel
	With (center) position, radius and random value outputs. Eevee does not yet support rendering point clouds, but an untested implementation of this node was added for when it does. Ref T92573
2022-01-13	Fix T94737: Cycles wrong normal map normal with OSL	Brecht Van Lommel
	Ensure valid reflection was moved elsewhere, should not be done in the node anymore.
2021-12-14	Nodes: Add vector support to Map Range node	Charlie Jolly
	This replaces lost functionality from the old GN Attribute Map Range node. This also adds vector support to the shader version of the node. Notes: This breaks forward compatibility as this node now uses data storage. Reviewed By: HooglyBoogly, brecht Differential Revision: https://developer.blender.org/D12760
2021-12-10	Fix T92036: `Magic Texture` in Volumetric World Shaders render differently ↵	William Leeson
	with the CPU and GPU When rendering volume surfaces in unbounded worlds the volume stepping can produce large values. If used with a magic texture node the values can results in a Inf float which when used in a sin or cos produces a NaN. To fix this the input values are mapped into the periodic range of the sin and cos functions (-2PI 2PI) this stops the possibility of a Inf occurring and thus the NaN. It also improves the accuracy and smoothness of the result due to loss of precision when large values are summed with smaller ones effectively removing the parts of the smaller number (i.e. those in the -2PI to 2PI range) that result in variation of the output of sin and cos.

2021-11-02	Fix T77681, T92634: noise texture artifacts with high detail	Brecht Van Lommel
	We run into float precision issues here, clamp the number of octaves to one less, which has little to no visual difference. This was empirically determined to work up to 16 before, but with additional inputs like roughness only 15 appears to work. Also adds misisng clamp for the geometry nodes implementation.
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.
