This is a bundle of two plugins for doing Fast Fourier
Transforms and Inverse Fast Fourier Transforms. If you're not familiar
with FFTs it's probably best to read up a bit on the pages I link to
below to better understand it's possible uses before starting to use
the plugins. The Fourier plugin will create either a "real" part or an
"imaginary" part depending on the "mode" parameter. It will also
conform the output to float and resize it to be the nearest power of
two square resolution since that is needed by the inverse algorithm.
You will need both the real part and the imaginary part of the "fourier
domain" to be able to convert back to the "spatial domain" again. The
images on the left are from the top a standard color wheel, it's real
part in the fourier domain and then it's imaginary part (all of them
have been cropped to fit the page nicely though, and are actually in a
square aspect ratio in Shake).
