Most modern PCs have a very powerful 3d video card with a GPU that is
hundreds if not thousands of times faster than the CPU for certain
calculations. I was thinking if some of the POV computations could be
offloaded to the GPU, we could speed up renders by a very large factor. The
big question is one of which routines thouse would be and which chunks of
the GPU could be utilized. Certainly matrix operations could be offloaded at
the very least, although I don't know to what extent that would improve
performance. It's just a shame that there is this uber-powerful floating
point processor sitting in most PCs that can't be used to help things move
along. What do others think?
