With regard to some past experiments:

How difficult would it be to implement a fast Fourier transform as an internal
POV-Ray / UberPOV / MegaPov function?

I'm assuming not doing this in SDL would be a whole lot faster.

It looks like everything's all set up to 'just' plug it in - the code is
available and free:
