Brecht Van Lommel	e6a84eb1b5	Cycles: add light falloff node, with quadratic/linear/constant falloff and a ... smoothing factor to reduce high values near the light. http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/More#Light_Falloff Note that this was already possible to do manually with the Ray Length, but this adds a convenient node for it. This commit also makes the mapping node min/max option work, fixing #31348.	2012-05-07 20:24:38 +00:00
Brecht Van Lommel	93df58160e	Fix #30966: cycles nan mesh vertices got set to (0, 0, 0), now remove them instead.	2012-04-16 08:35:21 +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
