Hi Rahul. Toe-In stereo is not proper stereo, rather its just a hack that kinda works OK as long as you don't need accurate stereo, but frankly its a pretty amateurish hack, suggesting that one doesn't really know or care what stereo actual means, or that one doesn't understand the maths required to properly manage the projection and view matrices when in stereo. The only time when Toe-In might be acceptable is in certain head-mounted displays when the projection matrix is identical for both eyes.
The stereo that's inbuilt into the OSG does a translate of view matrix and the projection matrix to provide proper accounting of the eye offset, screen distance and screen height. However, the built in support does assume a power wall setup, and doesn't have any built in head tracking. Robert.
