Brecht Van Lommel	db8024f4b5	Fix #29259: cycles issues on certain processors. Now two versions of the kernel ... are compiled, one SSE optimized and the other not, and it will choose between them at runtime.	2011-11-15 15:13:38 +00:00
Brecht Van Lommel	5fd67a3ba5	Cycles: enable multi closure sampling and transparent shadows only on CPU and ... CUDA cards with shader model >= 2 for now (GTX 4xx, 5xx, ..). The CUDA compiler can't handle the increased kernel size currently.	2011-10-16 18:54:27 +00:00
Brecht Van Lommel	66b1dfae89	Cycles: tweaks to properties and nodes ... * Passes renamed to samples * Camera lens radius renamed to aperature size/blades/rotation * Glass and fresnel nodes input is now index of refraction * Glossy and velvet fresnel socket removed * Mix/add closure node renamed to mix/add shader node * Blend weight node added for shader mixing weights There is some version patching code for reading existing files, but it's not perfect, so shaders may work a bit different.	2011-09-16 13:14:02 +00:00
Brecht Van Lommel	9b31cba74e	Cycles: some warning fixes, cpu device task tweaks, avoid unnecessary ... tonemap in non-viewport render, and some utility functions.	2011-09-08 18:58:07 +00:00
Brecht Van Lommel	48b4de3152	Cycles: ... * auto/fixed threads option is used now, patch by Thomas. * remove unused CUDA_LIBRARIES, library is dynamically loaded * fix mesh XML export operator for API update	2011-08-24 10:44:04 +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
