To the best of my knowledge, to do stereo rendering, you must expose two parameters, which are known by various names, typically:
1. Eye separation, the distance between the two stereo 'eyes'. This is in OSG as osg::DisplaySettings::setEyeSeparation. 2. Convergence, which is like a horizontal offset between the rendered views, or it can be thought of as the distance from the camera at which the two images converge. I cannot find any setting in SceneView or DisplaySettings for this. As the email below agrees, this is a vital parameter for any real stereo use. Perhaps i am just not finding it, is it in OSG somewhere? I did search the list archive, and found no relevant mention of 'convergence'.

I am afraid convergence is related to the use of rotated cameras (toe in). it produce keystone distortion ... ZPP does not use rotated cameras - it use just OpenGL viewport manipulation ... The result is similar for both approaches ... > Do you know of anyone using OSG-based software who is doing the > kind of stereo needed? Unfortunately i do not ... I cannot imagine anybody uses OSG in stereo without the possibility to adjust the ZPP or at least convergence ... Michal Husak Technical Director GALI-3D, s.r.o.
