Gads.. my apologies to those people who haven't seen stereogram images
before. I've gotten a few mail inquiries as to how to read those 3-d
pics I posted. Hopefully, I can help a few people here...
Generally, the x's at the top of the gibberish you see are your guides
for finding the background (usually) layer. If you look 'past' the
X's, trying to get two of the x's to overlap each other, then get your
eyes to focus on the lettering so they don't look so blurry, you may
be able to see the images that are hidden in the gibberish below.
This is the best trick I can think of to explain what you need to do..
they are not uuencoded files, and they are not set to any
super-special format that requres another machine or program to see.
You just need to figure out how to view them.. and that can take a
little while, training your eyes to do weird stuff.
Someone else asked me how I did these things...
Someone uploaded a uuencoded file here that contained mk3d.zip.
Unfortunately, mk3d.zip held an executable that works on an MS-DOS
machine .. and I'm using an Amiga 500. Fortunately, the person also
included the source code for the program. Unfortunately, the source
code was written in C, and I don't have a C compilor handy.
Fortunately, I'm a fairly bright person, and can convert C code to E
code, if I have to (E being the language I've been working with the
most on the Amiga.. it's really nice, although it has a few
limitations at the moment). Unfortunately, the differences between
the languages made the job sorta hard, and it took me almost 2 full
days of debugging and screwing around to get my own version of mk3d
work for the Amiga. Fortunately, when I was done, I came up with an
executable that was less than half the size of the MS-DOS executable,
and had a few extra functions it could do over the original.
So.. if you own an Amiga, and you have access to ftp, look Real Soon
Now (c) by Some Other Person, Inc. for mk3d.lha to appear at the
aminet sights... you'll be able to make these yourself.
mk3d for Amiga... another fine product of the Cheese Olfactory Workshop.

Must admit that I really like those 3D pics. The planet in particular
looks really cool. And since I'm the lucky owner of an Amiga, sounds
like I'll be able to have a go soon too 8).
Just a little hint for the people trying to make sence of them, you
CANNOT do it by simply crossing your eyes. You need to change focus
instead which is a very different thing as far as your eyes are concerned.

GAMES magazine had an issue on these stereograms a few years back. You
might find it easier to practice on them. They are amazing.

The technique that works best for me is to pretend to focus on the BACK
of your terminal. Pretend that you can see completely through to the
electron gun at the back of your tube. As you do that you'll see the
picture start to "swim" around & then you'll see shapes that "jump out"
at you.
Good luck,
Ron
P.S. My intro to Internet news was thru alt.3d which would post some
EXCELLENT SIRDS (single image random dot stereograms).

I'm glad you liked them... the planet one, if you haven't looked
carefully, has another planet set under the 'background' (without a
ring). This other planet (meant to be a sort of large 'moon') is to
the left of the other planet (your left, that is).
The amiga archive is apparently available now at wuarchive.wustl.edu
at systems/amiga/aminet/text/misc/mk3d.lha. Hurry and grab it now,
while you still can <grin>.
Enjoy!

COOL. Um, just for the record, was I right about the naked woman
being the body with arms stretched out?

OK, so now how do one eyed people, like myself view them???
Does anyone really think these qualify as ascii art? Being as I can't make
anything out, I guess I can't really judge.

Same here, I keep having the idea that I'm being fooled, and that
it's just a lot of gibberish. I'm not totally one-eyed (one sees
20% the other 120% of normal), but apparently enough not to be able
to see any sense in these pics.
And it's not that I can't do the focussing right, cause I'm very
good at forcing my eyes into unusual focusses (is that a word?)
and I'm sure I'm doing everything correctly.
Or is there anybody else out there with a 'lazy' eye, who has some
advice as to how to view these pics.

[about how to focus the 3D pics...]
Ok, I've been viewing these types of things for years, so I guess it's
a bit easier for me, but here's how to do it:
Start by working on the X's at the top only. The best pic would
be one with the X's closer together (the man/woman have them far
apart so they're harder).
Cross your eyes so that the X's in the middle come together in the middle:
X X (this is on the screen)
X (this is what you get when you cross your eyes)
Now adjust your head orientation so that the two X's perfectly line
up. You now have to try and focus on this ONE object. This is exactly
how REAL 3 dimentionality works, so it's not too hard.
When you get that focused, you should realise that it actually looks like
it is sitting /out/ of the page. Once you have this, practice shifting
focus between the X and something in the background (but not in the main
pic). This shifting abilty is neseccary to get the right effect with the pics.
Ok, now yo have that down, move down to the main pic. If you have a
look at it, you'll see large repeasting patterns the same distance apart
as the X's.
So go into cross eye'd focus again and try to get one part in focus.
The pics are made from several layers and the idea is to try and separate
these layers in your mind.
If it helps, here's some quite ideas of what the pics look like:
the naked woman::
-oo-
)(
||
The arms, body and legs ar in one plane (the object is actually located
over on the right of the mess) with the "area between the legs" being
into the screen with the background, and the breasts are actually two
more layers in front.
the naked man::
\i/
oo
Hmm, looks like two legs sticking up in the air with the penii in the middle
facing upwards and the balls (for lack of a different term) sitting out
another plane.
Planet::
_
<(_)>
I big slightly oval object in the center (one plane) witha ring going
around it (like saturn) which sits out another level.
the bat and ball thing::
o
o \ o
A bat going up at an angle with three balls around it at different levels.
All these are just SHAPES, not a shaded ascii pic or anything like
that. Once you get the hang of it, they do look really cool and you
can actually view them with very little effort at all.
Hope that helps,
Row.

You can't; all these images are are depths, so without stereoscopic
vision it's impossible to see them. You could write a program
that could crank out a page of depths based on what's in the image,
having it search out matching points and generate the depths from
them, but it would be a royal pain...

Unfortunately, SIRDS (or ASCII Stereograms as these are) take into
account the way each eye sees something in the distance. Points that
are close have a greater divergence than points that are distant (or is
it the other way around). Having only one eye deprives you of viewing
these just as it deprives you of depth perception in the "real" world.
Here's another example of an ascii stereogram which is viewed in the
same way as the SIRDS. This shows the word far as away from you and
the word near as close to you. Note that there are more "n"s than
there are "f"s which will make the "n"s look closer.
Subject: A genuine ASCII stereogram!
Here's an ASCII single image random dot stereogram for your enjoyment.
To get the 3d effect, you need to diverge (unfocus) your eyes
such that two adjacent letters in the same row come together.
To help you focus, try to make the two capital O's at the top
look like three. Once you've done that, the rest of the image
should jump out of the screen at you!
O O
n n n n n n n n n n n n n n n n n
f f f f f f f f f f f f f f
e e e e e e e e e e e e e e e e e
a a a a a a a a a a a a a a
a a a a a a a a a a a a a a a a a
r r r r r r r r r r r r r r
r r r r r r r r r r r r r r r r r
The other example I really like is this "room".
Try moving your head back from the screen and moving it about a bit
once you have focused on the image to increase the stereo effect even
more. Have fun! Perhaps we can have a whole series of these!

I take no credit for these stereo pics other than the fact that I saved
them. Sorry but attributes have been deleted.

no. i think that the monitor glows and that it is under glass has a lot
to do with how easy it is to view these things on a computer.
i think if you print them out and want to view them, do it in strong
light, (backlit might be best) and under glass, so you can focus
on the reflections. try to print them out on a good printer so
the letters are DARK.
i've printed them out, and haven't been able to view them either.
those are my ideas on how you might be able to do it.
don't forget to get really close to the picture. you should probably
hang the picture or prop it up so it isn't lying flat, but is vertical.
oh well. those are my ideas.

I thought that the 3-D pics were really amazing. The technique that I used to
figure them out was to pick a spot on my reflection in the monitor. Focus on
this one spot. ( Works especially well when wearing a light colored shirt ).
Let your eyes gradually go out of focus. The picture gradually appears. Hope
that this helps.
