Brecht Van Lommel	92764260d7	Cycles: add option to cache BVH's between subsequent renders, storing the BVH on ... disk to be reused by the next render. This is useful for rendering animations where only the camera or materials change. Note that saving the BVH to disk only to be removed for the next frame is slower if this is not the case and the meshes do actually change. For a render, it will save bvh files to the cache user directory, and remove all cache files from other renders. The files are named using a MD5 hash based on the mesh, to verify if the meshes are still the same.	2012-01-16 13:13:37 +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
