Ahh well I saw crystal eyes in your mail and assumed you wanted shutter
glasses. I have used the twinview stereo mode successfully for a
prototype projector which took 2 dvi inputs (left and right). No
changes to SCIRun are required. If your setup can give us a stereo
capable context we use it, and the stereo option becomes selectable.
What version of SCIRun are you running? I would like to verify that we
haven't introduced a bug with some version, wrt stereo.
