Brecht Van Lommel	7d9d9fa976	Cycles: use workgroup size from opencl, attempt to fix issue with apple opencl.	2011-09-05 12:24:28 +00:00
Brecht Van Lommel	f3ee10ce5c	Cycles: remove -Werror from opencl compile options, apple opencl on lion ... seems to give "no previous prototype for function" warning, but it doens't make much sense in opencl, seems like a compiler bug?	2011-09-05 08:23:01 +00:00
Brecht Van Lommel	db1664ed4c	Cycles: ... * Compute MD5 hash to deal with nvidia opencl compiler cache not recognizing changes in #included files, makes it possible to do kernel compile only once and remember it for the next time blender is started. * Kernel tweak to compile with ATI/linux. Enabling any more functionality than simple clay render still chokes the compiler though, without a specific error message ..	2011-09-03 10:49:54 +00:00
Brecht Van Lommel	67030aaf84	Cycles: optimizations for instances in scene updates before render starts, ... should load a non-trivial mesh instanced many times quite a bit faster now.	2011-09-02 16:15:18 +00:00
Brecht Van Lommel	1135875ab1	Cycles: ... * Fix crash in light path node * Fix struct alignment issue for cuda * Fix issue with instances taking up too much memory * Fix issue with ray visibility working incorrect on some objects * Enable OpenCL always and remove option, it has no dependencies so may as well * Refuse to load kernel if OpenCL version < 1.1, recent drivers are needed * Better error handling for OpenCL device * 3D views with rendered draw mode will now revert to wireframe on file load	2011-09-02 14:55:06 +00:00
Brecht Van Lommel	3c7dcd7a47	Cycles: compile opencl kernels in non-blocking thread, and don't crash on ... build failure but show error message in status text.	2011-09-02 00:10:03 +00:00
Brecht Van Lommel	1f7ac51c36	Cycles: fix opencl device bug that crashed on windows. Now shows diffuse ... meshes here on windows/nvidia.	2011-09-01 22:40:52 +00:00
Brecht Van Lommel	27102bfec4	Cycles: OpenCL library is now dynamically loaded so that blender doesn't crash ... if it's not installed on the system. Code copied from clew.h/clew.c in CLCC: http://clcc.sourceforge.net/	2011-09-01 19:00:23 +00:00
Brecht Van Lommel	6686f18948	Cycles: more opencl tweaks, status is: ... * kernel has shading nodes / textures disabled, amd/nvidia opencl compilers choke on these, need to figure out how to avoid this * works in cycles_test, not available as option in blender yet * kernel compiles and runs with opencl 1.1 from intel/amd/nvidia	2011-08-11 12:36:08 +00:00
Brecht Van Lommel	63d4bafff5	Cycles: some steps to getting OpenCL backend to compile.	2011-05-20 12:26:01 +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
