I understand that stereo configure renders two times with different rojection/view matrices.
Actually, my question was how to compute different projection/view matrices for left and right eyes. OpenGL routine by a user has only one project/view matrix for a single view, and sometimes the project/view matrices are mixed with model transform matrices - which means that we cannot correctly infer viewing parameters. Even worse if we use shaders. So what is equalizer's technique to correctly infer viewing parameters? Or do users have to provide viewing parameters explicitly using some sort of API? Thanks in advance. On Wed, May 20, 2009 at 2:20 AM, Stefan Eilemann <[email protected]> wrote: > Hi Won, > > On 19.
