First of all, great work on bring CUDA to the OSG! I'm just getting schooled
up on it right now with the main goal being to duplicate what the PostProcessGL
example in the sdk is doing. According to their comments, this requires the
following:
1 - render the scene to the framebuffer
2 - copy the image to a PBO (pixel buffer object)
3 - map this PBO so that its memory is accessible from CUDA
4 - run CUDA to process the image, writing to memory mapped from a second
PBO
6 - copy from result PBO to a texture
7 - display the texture
I've mainly struggling with steps 1,2, and 3. What's the best way to do this?
