CrystalEyes 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 CrystalEyes 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:
Available on
workstations equipped with quad-buffered stereo graphics subsystems only
(such as SGI InfiniteReality, Sun Expert3D, HP FX-10)
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,
sometimes requires the monitor to be in a lower-resolution display mode
since it requires twice as much video memory over a normal non-stereo
display. The monitor 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.
