I spent last weekend porting my SW-only renderer to CUDA. I blogged about my results here, where I also share my code in GPL. Note that this is not about “doing graphics with CUDA instead of OpenGL” - it was just an exercise to port some algorithms (that happen to be graphics algorithms) to CUDA, and my experience in doing so.
Feel free to comment on my efforts:
any positive feedback and/or algorithmic suggestions most welcome.
please refrain from bashing, I tried to be objective :-)
