Right on the heels of the NVidia OptiX announcement, a new tutorial from the Alexandra Institute shows how to build your own CUDA accelerated ray-tracing system.
This little tutorial will not state that the GPU thing is the only way to go or try to preach something. But it will hopefully help you to get started using CUDA to accelerate ray tracing. I have been writing a lot of shaders for other applications so it was very natural for me to experiment with a GPU implementation. So the natural choice would be to use Nvidia’s CG or glsl. But i decided to try Cuda, because i wanted to learn what kind of beast it is and second it should be easier to code.
