Brecht Van Lommel	72d2d05770	Cycles: border rendering support, includes some refactoring in how pixels are ... accessed on devices.	2011-12-20 12:25:37 +00:00
Brecht Van Lommel	eb2baf9abc	Fix #29274: problem compiling cycles opencl kernel from directory with spaces. ... Some drivers don't support passing include paths with spaces in them, nor does the opencl spec specify anything about how to quote/escape such paths, so for now we just resolved #includes ourselves. Alternative would have been to use c preprocessor, but this also resolves all #ifdefs, which we do not want.	2011-11-22 16:38:58 +00:00
Brecht Van Lommel	47853bf6f6	Cycles: OpenCL tweaks ... * Reduce kernel arguments size, helps compile for apple nvidia. * Fix use of unitialized variable in displace kernel. * Use build flags in opencl kernel md5 hash. * Reorganize code for kernel feature #defines a bit.	2011-11-22 13:15:19 +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

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
