Quad-buffered frame-sequential stereo is available on workstations such as SGI InfiniteReality, Sun XVR-1000, XVR-4000, HP SV6, NVidia Quadro FX, and others. This mode provides separate left and right eye frame buffers. It allows the a window display in stereo, while all other windows appear as normal. Quad-buffered stereo modes usually display at lower-resolution since they require twice as much video memory as non-stereo display modes. The display must be set in a stereo-capable mode before starting VMD. On SGI systems, one must use either the setmon or xscreen utilities to configure the display mode. On Sun systems this is done using the fbconfig utility. HP systems use the sam utility for display configuration. Windows machines use the Display Properties tab to control video board display mode settings.
Once set in the proper display mode, start VMD as normal, and select `CrystalEyes stereo' from the Display form. The image should switch to two images nearly superimposed, but slightly offset.
