I am trying to figure out the FFT of selection over time filter. My user is trying to use it on a velocity point vector field (in 2d, no less). So, a few questions: * This filter doesn't work on point data, but only cell data. Shouldn't it work on point data? * This filter doesn't create magnitudes of vectors. Shouldn't it if needed? * Since an FFT spans some array of data, shouldn't this span be changeable? For instance, 16 or 32 or 128? * Does this filter even work correctly? Has anyone ever used it? * Can anyone create a simple example using this filter?
Thanks, Alan
