[vtkusers] Problems with reslice, transforms

[Jim Morash]

Hi folks,
I'm using vtkImageReslice in a first-approximation attempt to implement
Fourier volume rendering
(ref. http://graphics.stanford.edu/papers/fourier,
http://graphics.stanford.edu/papers/fvr)
and I've run into some interesting bugginess (or at least rounding
errors, or something) while trying to create a user interface that sets
up a few control sliders to rotate the slice plane around in the data
volume. I'm putting my code and the test data up at

http://web.mit.edu/jmorash/www/vtk/

so that I don't have to bomb the whole list with it, but if any of you
could take a look I'd very much appreciate it.
thanks
