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
2018-07-06	Cleanup: strip trailing space for cycles	Campbell Barton

2018-06-14	Cycles: Query XYZ to/from Scene Linear conversion from OCIO instead of ↵	Lukas Stockner
	assuming sRGB I've limited it to just the RGB<->XYZ stuff for now, correct image handling is the next step. Reviewers: brecht, sergey Differential Revision: https://developer.blender.org/D3478
2016-04-05	Revert "Cycles: Remove the Preetham Sky model."	Thomas Dinges
	This reverts commit d91316dc672dc1ee69fbd24d2f00124a24b75c6b.
2016-04-03	Cycles: Remove the Preetham Sky model.	Thomas Dinges
	The improved Hosek / Wilkie model was added during my GSoC 2013 and the default since then. The older model was kinda kept for compatibility, but after more than 2 years it's time to remove it. The Hosek / Wilkie model is more realistic anyway, and people who really want a day / night transition can mix the Sky Shader with another one (e.g. color) and fade between the two.
2016-02-03	Cycles: Cleanup, indentation and braces	Sergey Sharybin

2014-12-25	Cleanup: Fix Cycles Apache header.	Thomas Dinges
	This was already mixed a bit, but the dot belongs there.
2014-05-03	Code cleanup: Add -Werror=float-conversion to Cycles	Campbell Barton

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.
2013-08-28	Cycles / OpenCL:	Thomas Dinges
	* Some fixes for OpenCL, was broken after recent changes.
2013-08-28	Cycles / Sky Texture:	Thomas Dinges
	* Added a new sky model by Hosek and Wilkie: "An Analytic Model for Full Spectral Sky-Dome Radiance" http://cgg.mff.cuni.cz/projects/SkylightModelling/ Example render: http://archive.dingto.org/2013/blender/code/new_sky_model.png Documentation: http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/Textures#Sky_Texture Details: * User can choose between the older Preetham and the new Hosek / Wilkie model via a dropdown. For older files, backwards compatibility is preserved. When we add a new Sky texture, it defaults to the new model though. * For the new model, you can specify the ground albedo (see documentation for details). * Turbidity now has a UI soft range between 1 and 10, higher values (up to 30) are still possible, but can result in weird colors or black. * Removed the limitation of 1 sky texture per SVM stack. (Patch by Lukas Tönne, thanks!) Thanks to Brecht for code review and some help! This is part of my GSoC 2013 project, SVN merge of r59214, r59220, r59251 and r59601.
2013-08-18	Cycles: relicense GNU GPL source code to Apache version 2.0.	Brecht Van Lommel
	More information in this post: http://code.blender.org/ Thanks to all contributes for giving their permission!
2013-08-17	Cycles / Sky Model:	Thomas Dinges
	* Replaced the Preetham model with the newer Hosek / Wilkie model: "An Analytic Model for Full Spectral Sky-Dome Radiance" http://cgg.mff.cuni.cz/projects/SkylightModelling/ * We use the sample code data, which comes with the paper, but removed some unnecessary parts, we only need the xyz version. * New "Albedo" UI paraemeter, to control the ground albedo (between 0 and 1). * Works with SVM only atm (CPU and CUDA). Example render: http://www.pasteall.org/pic/show.php?id=57635 ToDo / Open Questions: * OSL still uses the old model, will be done later. In the meantime it's useful to compare the two models this way. * The new model needs a much weaker Strength value (0.01), otherwise it's white. Can this be fixed? * Code cleanup.
2013-06-11	Cycles / Wavelength to RGB node:	Thomas Dinges
	* Added a node to convert wavelength (in nanometers, from 380nm to 780nm) to RGB values. This can be useful to match real world colors easier. * Code cleanup: Moved color functions (xyz and hsv) into dedicated utility files. Remove svm_lerp(), use interp() instead. Documentation: http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/More#Wavelength Example render: http://www.pasteall.org/pic/show.php?id=53202 This is part of my GSoC 2013. (revisions 57322, 57326, 57335 and 57367 from soc-2013-dingto).
2013-06-10	Cycles / Code cleanup:	Thomas Dinges
	* Move hsv and xyz color functions into the dedicated util files (util_color.h and node_color.h). * svm_lerp moved into util_math.h and renamed to lerp_interp, as it's used for the wavelength node now as well.
2011-05-20	Cycles: some steps to getting OpenCL backend to compile.	Brecht Van Lommel

2011-04-27	Cycles render engine, initial commit. This is the engine itself, blender ↵	Ton Roosendaal
	modifications and build instructions will follow later. Cycles uses code from some great open source projects, many thanks them: * BVH building and traversal code from NVidia's "Understanding the Efficiency of Ray Traversal on GPUs": http://code.google.com/p/understanding-the-efficiency-of-ray-traversal-on-gpus/ * Open Shading Language for a large part of the shading system: http://code.google.com/p/openshadinglanguage/ * Blender for procedural textures and a few other nodes. * Approximate Catmull Clark subdivision from NVidia Mesh tools: http://code.google.com/p/nvidia-mesh-tools/ * Sobol direction vectors from: http://web.maths.unsw.edu.au/~fkuo/sobol/ * Film response functions from: http://www.cs.columbia.edu/CAVE/software/softlib/dorf.php
