Yes, that is an excellent thought. I was considering this possibility
for speeding up common interpolation, image transformation and
resampling, as well.
Kriging in realtime, anyone? ;)
Of course, this would have to be implemented in a GPU-specific library.
NVidia has the CUDA SDK, which is not open source at the moment, but
the pressure is on:
ATI already seems to have their stuff (CTM) opened up.
Maybe a proof-of-concept GPGPU module would make a nice little SoC
