Well, since it seems that no-one is going to guess the right
answer, I'll have to post it... 

There _is_ a method for generating a hologram from a series of
still images.  (Hasn't anyone ever seen the "Kiss" hologram?
how do you think that was made?)  Basically the method involves
taking a series of still images (from all around the object, or
in the case of the "Kiss" hologram, from around it and also
over time/movement), and printing holograms of the still images
as "slit" holograms (terminology may be off there, don't have the
big holography book handy here at the office).  Basicaly what
this means is that over the width of the final hologram sheet,
one prints many vertical stripe holograms, each one from a 
single frame of the still images.  (If one has any intelligence,
one prints them in a logical order such that they are in
sequence in time, and in sequence as the camera moves...)  When
viewed, the eye sees these sort of like one sees lenticular
prints, each eye receives the image of a different vertical stripe,
and puts the 2 images together to see 3D.

I can post further information, and suggest a great book on
the subject, if I can remember to look on the bookshelf
when I get home.

...and even some who get news don't get alt.3d.  The last message posted
to the old mailing list was from me, so a lot of people contacted me to ask
where the list went.  I told them about alt.3d, and they said it was not
available to them.  It'd be a shame to exclude those folks, if you're
willing and able to set up a mailing list.

The idea of also forwarding notes to alt.3d is a good one, since I know for
a fact that some readers who were interested in other aspects of 3D became
interested in stereo photography just from happening to see postings about
it here.  (By golly, if enough people get hooked, maybe somebody out there
will start making stereo cameras again! :-)  

I just hope you can get a copy of the address list from the old moderator,
or else how will the non-alt.3d-ers know the new mailing list exists?

I've seen it.  Near as I could tell, it is all on a regular old
videodisc played on a regular old video screen, with mirrors to give the
illusion of an upright image floating on top of the game.  I wasn't too

I've written a small C program to output random-dot stereograms as PostScript
files.  It works quite well for me, but I have one small question pertaining
to the images.

How much is the the percieved depth change per pixel shift?  Like, if I have
my focusing trianges 90 pixels apart, and I make a 5 pixel shift, how much
will I perceive the change in depth to be?

If anyone wants this program, they are welcome to it.  However, it's not
very robust .... most of the constants are hard coded, for example :-)  I
plan on making the program more general eventually.

Thanks for any replies.

There is a process where you can render stills of the various  views of a 3D
object and those are put together to form a hologram.  This technique was used
to create some images of the Siggraph logo a few years back (the hologram was
displayed at the entrance to the registration hall).  I cannot remember the
company that did it right now, but it can be done.

The process of synthesizing a hologram from 3D computer graphics is possible
and has been done. The process is basically the same used to produce the
Michael Jordan hologram cover for Sports Illustrated last year. A short segment
of film is shot of a subject as it (either the camera or the subject) rotates.
Frames frome the film are then arranged as slit holograms that produce many
sets of stereo pairs when viewed. In 1988 IEEE's journal had a cover that
had a computer synthesized hologram from "Tin-Toy", a Pixar produced short.
Both the IEEE journal and the Siggraph hologram claimed to be the first
computer generated animated embossed hologram. I believe the Siggraph one came
first in 1987. At Siggraph this year the Lazzerus Co. had some of the
holograms mentioned. I believe that they produced the original. I was lucky
enough to get a few before they ran out.
If you see anything in this post that is grossly incorrect, please post to

Has anyone else seen the hologram video game at the arcades?  It is of the same
type as Cliff Hanger, Space Ace, and Dragons Lair.  Its called Time Traveller,
and you play a cowboy that somehow got chosen as the DefenderOfTheUniverse(tm),
and you go through a bunch of scenes where every once in a while you have to
make a decision as to what to do, like fire your gun, or jump over a laser beam.
It was filmed with live actors and has real voices in it.  It even has special
effects, so someone knows how to manipulate the 3D film.

We seem to have lost our photo 3D mailing list.  Should we start another?
Alt.3d is great but it seems to be serving other, equally valid, purposes.
Those few  posts on the photographic aspects of 3D seem to get lost in the
large number of posts on other subjects.  This discourages further photo 3D
posts.  Also, some 3Ders can't get news and they would like to be involved
with a list they can access.

On the other hand, for many photo 3Ders, this one group is great because it
covers all of their areas of interest.  For them, the proposed mailing list
could be configured to forward all posts to alt.3d.

Since this proposal is for something akin to splitting the group, I'd like
to see some discussion.

Why do I bring all of this up?  We have a local guru who has graciously
offered to set us up with a list if that is our desire.

but I am sure that the new Amiga 4000 would blow that away.
Don't have one myself, but I would like to have some info on them...

	As far as I can tell, they use a curved mirror to project the image
into space.  It's reflecting a tv monitor. . .I've seen a similar effect
in magic/trick shops.  They have a black ovalur thing that looks like a
flying saucer with a hole in the top.  Floating in the hole is a penny
that looks real, but the penny is actually at the bottom of the object. 
That's SORT OF how Sega's Time Traveller and Holoseum games work.
