Lens Correction
But this looks like it is only for pincushion distortion.
I need to specify an "arbitrary" warping. The warping is specifyed by the pixel displacement. Instead for pixel (i, j) going to (i, j) it needs to go to (m, n). I have this correspondence for every pixel in the display. The warping is not symmetrical. Any way to specify this in the vizlens?
Cheers,
Bob Gray
