Crystal Eyes Stereo

Crystal Eyes stereo refers to a special hardware option available on Silicon Graphics workstations that allows one to view three-dimensional objects through the use of a special display monitor mode and special stereo viewing glasses. Stereographics Corp. is one such supplier of these glasses. This mode also requires special infrared emitters to synchronize the stereo glasses with the display monitor.

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:

Stereo in a window (aka new-style stereo):

Available on workstations equipped with Reality Engine2-style graphics subsystems only (such as Onyx or Power Onyx machines), this mode provides separate left and right eye frame buffers. It allows the user to have a window display in stereo, and the other windows appear as normal. Using this mode, however, requires the monitor to be in a lower-resolution 960 by 680 display mode. The monitor must be set in this mode before starting VMD. To do so, do one of the following:

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.

Regular stereo mode:

All stereo-equipped workstations can use this display mode, including Reality Engine 2 workstations. VMD uses OpenGL code to acquire a stereo-in-a-window capable video display mode or visual, using built-in code.
