[vtkusers] Real-Time Image Warping

[David Gobbi]

Hi Jorge,

For real-time image warping in VTK, you would probably have to go with
256x256 images in order to achieve the 10Hz goal that you are aiming
for.  For warping a 512x512x100 volume in real time, I think your only
option would be to use the GPU.
