It's certainly possible to write a ray tracing rendering path for the OSG, others have already done work like this using the CPU based raytracing. Other OSG groups have also worked on CUDA integration. The thing to look for is examples of doing raytracing with CUDA. > 2. does only osgViewer need to be replaced or other modules do as well? You can integrate OpenGL contexts with CUDA contexts so you can use the CUDA results in your OpenGL (osgViewer) GraphicsWindow. For instance osgCompute that integrates OSG with CUDA integrates can work with osgViewer so it's not an either/or decision, you can mix the two. The NVidia diagram doesn't show this type of integration though, but perhaps their diagram doesn't quite reflect that actual implementation, or perhaps they don't integrate them. Robert.
