Fast Fourier Transforms and the GVX

[Tom Wolf]

In reading through the literature on the latest Graphics machines(I believe
they are called GVX's), I see that they use Fast Fourier Transform chips in
the graphics pipeline. 

As I have an application that requires thousand's of Fourier Transforms, 
I am curious as to whether you can use the FEEDBACK function to help
crunch the FT's? Does anyone know if this is possible?


Several of us have been trying to figure out what Fourier Transforms are used
for in graphics processing? Any ideas?



Thanks,

Tom
