Thomas Dinges	9020df976c	Cycles / Wavelength to RGB node: ... * 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 21:55:41 +00:00
Dalai Felinto	ded5e9cd23	clamp for Mix node ... the implementation was following my early commit for Math node I haven't had a chance to run those through Brecht, but would like to do eventually. (they work fine though)	2012-08-30 06:31:02 +00:00

Dalai Felinto	4fd2736487	HSV Color Node for Cycles ... ......................... note, the OSL code has a problem. In the original node the input and output nodes have the same name (Color). So this will be fixed here once Brecht come up with a nice autorenaming (or we do a doversion patch) for that.	2011-12-02 16:57:37 +00:00

Ton Roosendaal	da376e0237	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	2011-04-27 11:58:34 +00:00
