Stereo buffers which are meant to be used to generate stereoscopic images are not supported by most OpenGL implementations for windows.
A common method to generate stereo images without the use of stereo buffers is to use interlaced left and right images with an interlaced video mode.
Yet, there are now 3D glasses (Elsa revelator, Asus VR 3D) that are used in synchrony with rapidly switching non-interlaced images on the monitor.
How does the video card manage to follow a refresh rate of 100Hz+ without the use of stereo buffers while playing 3D power demanding games (or maybe it does use some kind of stereo buffers) ?
Also, almost any game can be played with those glasses, even if it has no built-in function to generate the left and right images. How are these images generated ? By a special driver ?
Also I think that additionnal transformations are needed to generate these images (translations & rotations).
Thx for your replies
