Brecht Van Lommel	2d0a586c29	Cycles OpenCL: keep the opencl context and program around for quicker rendering ... the second time, as for example Intel CPU startup time is 9 seconds. * Adds an cache for contexts and programs for each platform and device pair, which also ensure now no two threads try to compile and write the binary cache file at the same time. * Change clFinish to clFlush so we don't block until the result is done, instead it will block at the moment we copy back memory. * Fix error in Cycles time_sleep implementation, does not affect any active code though. * Adds some (disabled) debugging code in the task scheduler.

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
