FFT

[Gavin Tabor]

Dear All,

This is probably a no-brainer, but:

I have a 2d array of data in the form of a vtkStructuredPoints
object. I want to do an FFT on this (actually, I want to convolve
it with various types of filter, but the FFT will do to start with).
VTK has various types of FFT algorithm, but they all seem to
operate on images - vtkImageFFT for example. Can I input (and output) 
other forms of structured data for this?
