Robert- I'm glad this topic was brought up. I am doing some work with non-linear distortion correction and have taken the code in osgViewer for doing the spherical distortion and made it more generic to accept a grid of points that represent the distortion mesh. This is just what the spherical distortion routines are doing in osgViewer, except rather than computing the points, it takes a rectangular grid.
What I would like to do is integrate this distortion code into osgViewer to allow for more generic distortion grids to be used. The existing spherical distortion routines could use this by computing the appropriate distortion grid and supplying that grid to this more general distortion generator. The result would be that the existing spherical distortion would still work, and more general distortion patterns can be given too. If you think this would be useful, let me know and I'll integrate the changes and make a patch.
