Some notes about code status: * The Blender modifications were fairly quickly put together, much more code polish and work is needed to get this to a state where it can be committed to trunk. Files created with this version may not work in future versions. * Only simple path tracing is supported currently, but we intend to provide finer control, and more options where it makes sense. * For GPU rendering, only CUDA works currently. The intention is to have the same kernel code compile for C++/OpenCL/CUDA, some more work is needed to get OpenCL functional. * There are two shading backends: GPU compatible and Open Shading Language. Unfortunately, OSL only runs on the CPU currently, getting this to run on the GPU would be a major undertaking, and is unlikely to be supported soon. Additionally, it's not possible yet to write custom OSL shaders. * There is some code for adaptive subdivision and displacement, but it's far from finished. The intention is to eventually have a nice unified bump and displacement system. * The code currently has a number of fairly heavy dependencies: Boost, OpenImageIO, GLEW, GLUT, and optionally OSL, Partio. This makes it difficult to compile, we'll try to eliminate some, it may take a while before it becomes easy to compile this.
