New product announcement seen in IEEE Computer, May 1984:
CUBIC SPREADSHEET FOR IBM PC ANNOUNCED
Datamension Corporation has introduced Report Manager,
an advanced version of their 3-D spreadsheet for the
IBM PC....

Do they send the special glasses or do I have to furnish my own?ab3@stat-l (Rsk the Wombat) (05/18/84)
Hey, wait a minute!! I worked on that when the company was
"The Image Producers", and I don't remember them issuing 3-D glasses...
hmm...maybe that's why I couldn't ever quite get the pseudo-curses package
to work correctly.

No, No, No... You don't understand... IBM supplies the glasses - its a new invention - VIRTUAL spread (sh*t!)

Glasses? Don't be silly, you need two monitors, and you look at one with one eye and one with the other (whatever you do, don't get them backwards....) -- Randwulf (Randy Haskins); Path= genrad!mit-eddie!rh

Oh yeah? RCA developed a tricolour CRT which (through some screwy design
of the faceplate) achieved compatible 3-D images in NTSC without any glasses
at all. This was in the 70's. Also, there is currently active research at
University of South Carolina at Columbia in the 3-D area (again, without
glasses.) They have a product which, if you don't watch it on a teeny-weenie
9" RCA (like I did the first time it was aired by local TV WSOC) is very
realistic. Like mindblowing....
Pseudo-3D displays are also being used in diagnostic radiology for showing
MR images of working living hearts as well as reconstruction from CT series
to determine bone contour in those cases where faces are obliterated in auto
accidents/birth defects. This work is truly outstanding. (Radiology: April 84)
3-D spreadsheet. Why not ?

I've heard about this 3-D TV at U of So. C., but have never seen any explanation of how it works without glasses. Anyone out there know?
Kyle.wbst@XEROX.ARPA (05/26/84)
It sounds like you've seen a demo of this thing. If so, how did it look to you in terms of realistic 3D effect? Also was it in color, or black & white? Earle.

I have heard of two ways of producing 3-d color TV without
glasses. The first creates a "virtual image" of a CRT with mirrors
or lenses, which vibrate to make the image move in the 3rd dimension.
This creates an fake image the same way concave mirrors do (you might
remember it from high-school physics) - the three-d effect is not very
good unless you're "used" to seeing three-d this way.
The other method is to make the glass front surface of the
CRT with many narrow, vertical ridges - like long, thin prisms running
up and down the front of the screen. For each ridge there should be
several (four to eight will do) columns of pixels displayed on the
screen. The ridges make each of the eight columns of pixels visible from
only one angle. Typically, your left eye will see only the first
column of each group of eight and your right eye will see the fourth.
The left-eye image is made different from the right-eye image by the
computer, and you have three-d. Some of you might have seen three-d
postcards or pictures with this type of surface sold as novelties.

I hate to bring Mickey Mouse stuff like this up on a high class network like this but I was in Epcot center last week and they have the finest 3D movie I've ever seen. No sex or monsters, and you needed glasses, but it was quality stuff. Has anyone else seen this?
