Cycles render engine, initial commit. This is the engine itself, blender 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

Cycles: procedural texture nodes reorganization. This will break existing files using them, but rather do it now that I have the chance still. Highlights: * Wood and Marble merged into a single Wave texture * Clouds + Distorted Noise merged into new Noise node * Blend renamed to Gradient * Stucci removed, was mostly useful for old bump * Noise removed, will come back later, didn't actually work yet * Depth setting is now Detail socket, which accepts float values * Scale socket instead of Size socket http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/Textures
