quad buffered stereo?

[halley]

I've just been evaluating Vizard with the downloadable trial copy, so I don't know if it is complete or not.

Does Vizard support a frame-alternating stereoscopic mode? OpenGL refers to this as "quad buffered stereo" mode.

The only stereo imaging I've seen in the trial copy is a side-by-side format, where each eye's viewport is half of the screen, and both eyes get the full refresh rate.

Quad buffered stereo modes is important for passive (polarized glasses) or active (shutter glasses) projection screens.
