OSG will work out of the box in QUAD_BUFFER mode. The only thing you'll have to do is to declare some parameters to adjust stereo with the geometry of your projector : See : http://www.openscenegraph.org/projects/osg/wiki/Support/UserGuides/StereoSettings OSG_STEREO ON Turn stereo on OSG_STEREO_MODE QUAD_BUFFER Use quad buffered stereo when in stereo. OSG_SCREEN_DISTANCE 0.50 Set the distance the viewer is from screen in metres (default shown) OSG_SCREEN_HEIGHT 0.26 Set the height of image on the screen in metres (default shown) OSG_SCREEN_WIDTH 0.325 Set the width of image on the screen in metres (default shown) OSG_EYE_SEPARATION 0.06 Set the eye separation - interoccular distance (default shown.) And that should be ok for the OSG side. On the hardware side, you'll have to connect cables :D and check the stereo enable box in the nvidia settings panel. You should have the same result than with anaglyphic stereo (a better result in fact). Luc > Now, I think this setup requires (and supports) quad-buffer > stereo.
