Hi-- A week or two ago I said I would post code for making the disparity change in stereo viewing. If you do not have a card that supports stereo then this won't work.
Compile BasicRecipeJ3D and DisparityBehavior. Make sure you run with the option -Dj3d.stereo=REQUIRED Be careful when you run this because changing the disparity too much or too fast can make you sick in a hurry! Alex
