2013-06-04	Cycles:	Thomas Dinges
	* Revert r57203 (len() renaming) There seems to be a problem with nVidia OpenCL after this and I haven't figured out the real cause yet. Better to selectively enable native length() later, after figuring out what's wrong. This fixes [#35612].
2013-06-03	Cycles / Math functions:	Thomas Dinges
	* Rename some math functions: len -> length len_squared -> length_squared normalize_len -> normalize_length * This way OpenCL uses its inbuilt length() function, rather than our own. The other two functions have been renamed for consistency. * Tested CPU, CUDA and OpenCL compile, should be no functional changes.
2013-05-20	Math Node:	Thomas Dinges
	* Added a Modulo operation to the math node, available in Compositor, Shader and Texture Nodes.
2012-12-20	Cycles OSL: diffuse_toon and specular_toon closures. These are toon shaders with	Brecht Van Lommel
	a size parameter between 0.0 and 1.0 that gives a angle of reflection between 0° and 90°, and a smooth parameter that gives and angle over which a smooth transition from full to no reflection happens. These work with global illumination and do importance sampling of the area within the angle. Note that unlike most other BSDF's these are not energy conserving in general, in particular if their weight is 1.0 and size > 2/3 (or 60°) they will add more energy in each bounce.

2012-11-23	Fix #33267: cycles math node power gave different results for CPU and GPU. The	Brecht Van Lommel
	GPU variants do not support pow(-1, 2), it doesn't check for even exponents, do manually now.
2012-08-29	Cycles bugfix: [32431] Cycles Math Node : Clamp does not work	Dalai Felinto
	the OSL solution is slightly different than the svm, but I think it's fine. thanks Lukas Toenne for helping with a fix on the original patch
2011-08-10	Cycles: amd opencl compatibility fixes.	Brecht Van Lommel

2011-05-16	Cycles: fix vector math subtract not working correct, patch by Sanne.	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
