At the Sun Users Group show last week (Dec 7-10, San Jose, CA),
called SUGshow'92, I saw something that may be of great interest
to Mma users. It certainly excites me. It is a 3-D viewing system.

I have seen various pervious attempts to achieve 3-D for computer
displays, but this is the first I have seen that is convincing
and looks like it might become a standard approach.

The system was first shown at Siggraph'92. It utilizes special
glasses with LCD lenses that alternately become opaque or
transparent at the rate of 120 cycles per second. The glasses
are synced to the crt display, which alternates right and left
eye images, also at the rate of 120 cycles per second. Sync is
maintained using an infrared link, consisting of a small box
usually placed on top of the video display, that must be in line
of sight with the glasses to maintain the link, but there is
no other connection between the glasses and the video display.

we have been using this technology for a few years here at merck for
molecular modeling on silicon graphics workstations and are very
pleased with it. speaking about 3D graphics in Mathematica, though,
recalls to mind my desire for even simple stereo pair rendering of 3D
objects in Mathematica. the color and shading model that is used works
fine for the front end (a macintosh in my case), but for reports that
are to be photocopied, a line drawing as a stereo pair works much
better. here is one more suggestion for graphics enhancement for wri to
