The internet is full of information...but its not
always comprehensible. For example: wikipedia brings up as nearly a
technical explanation (in a concise form ;P ) as the fftw.org
<http://fftw.org>
FFT is used with periodic waveform interaction to tease out values
--decompose into sine components. (I hope that I'm not mangling the
meaning by trying to cram it down into one sentence) This link does a
better job at explaining it:

There are so many uses for FFT. It is a valuable (arguably critical)
tool for all sorts of signal processing ranging from noise filtering
to 3D tracking. But perhaps a more immediate and
practical application of it in the 3D world is its facilitation of the
deformation calculation of Amaan's aaocean polygonal surface

I hope this helps :)
