There are presently two types of Crystal Eyes stereo modes available on SGI machines; which one is used depends on the available graphics hardware (see the man page stereo(7)). Follow the outline below for the relevant graphics option:
This will change the display characteristics to the lower resolution mode, with a higher display frequency (108 Hz), but will not change the managed size of the X-Window display screen. To change back to the normal mode (after running VMD), execute the command:
When the computer is in the lower resolution mode, run VMD as normal, but note that the lower resolution means the windows will appear larger and may end up sometimes positioned off-screen. If this is a problem, a system superuser should set the video mode permanently with the commands listed in the next item.
Once set in the proper display mode, start VMD as normal, and select `Crystal Eyes stereo' from the Display form. The image should switch to two images nearly superimposed, but slightly offset.
