Hi, I know that povray enables several kinds of image processing, if you load an
image as a pigment pattern. I'm listening to some advanced lectures on
microscopy, and they are talking about doing a Fourier transform on an image.
Q: How easy is it to do this in povray? TIA

I don't know, but, if you save as a .JPG, then, there is a Fourier
transform performed while encoding the image.

I haven't been able to do it - yet.
But I've been getting better at implementing stuff like this.
I'm thinking that if you need it any time soon - use a 3rd party package.
It's been a while since I've wrestled with the FFT.
