This is something I would really like to see in OSG. An easy way to do stereo asymmetric displays. Particularly for a head-tracked display. I have never done it, but I have spent some time digging through source code, doxygen files, and the mailing list and I know all the blocks are there. OSG easily supports stereo, has a way to specify skewed projection matrices, and supports camera callbacks for continuous head-tracking, but nothing puts it all together.
It would be nice if there was an interface to initially specify the location of the display(s), then at each time-step pass it the 6DOF location of the eye. The code would automatically compute and update the cameras with the proper projections. Just wishing out loud... :) PaulB Jean-Sébastien Guay wrote: > Hi Bob, > >> My goal here is to create .cfg files that describe orientation of the >> display surfaces.
