Fast fourier transform plugin

Hi Everyone,

This is one for the math nuts: A plugin to generate the real and imaginary components of the fourier transform of the heightfield. The plugin is available from:

http://www.bundysoft.com/wiki/doku.php?id=plugins:calc:atcalc_fft

This plugin uses the FFT algorithm, so it's limited to square power of two sizes. Note also that you can apply the reverse transform to recover the heightfield.

Is it useful? Probably not, but I thought it might be fun to try. Perhaps someone might find a deeper meaning to these patterns...

Cheerio,
Aaron

Hi All,

The FFT plugin has been updated with a number of improvements (see plugin page for details). I'm idly considering using it for terrain synthesis and/or filtering algorithms.

Cheerio,
Aaron.
