----- How Stereograms Work --------------------------------------------
-----------------------------------------------------------------------
Let's start with a simple repeating pattern. First we'll examine viewing
stereograms wall-eyed (focusing beyond the picture).
Adam
Adam Adam <-- PERCEIVED IMAGE (3D)
\
\ \
\ \
Adam Adam Adam Adam <-- ACTUAL PICTURE (Flat, 2D)
\ \
\ \ <-- LINES OF SIGHT FROM EACH EYE
\ \
(*) (*) <-- EYES
As shown in the above graphic, the lines of sight go through different
(but identical) words. The eyes must be directed to just the right level
behind the picture to get the two "Adams" to line up. When they do line
up, a single "Adam" appears at the level shown behind the picture.
This is why it is easiest for some people to look at stereograms behind
glass. You simply look at your reflection, which appears to be behind
the glass at about the same level as the 3d stereogram image. More on
this later.
So, why is the second "Adam" in the above image "deeper" than the other
two? Since the next two "Adams" that line up are FARTHER apart than the
first two, your eyes must diverge a little more to get them to line up.
away.
This causes the next "Adam" to appear deeper in the image.
Adam
Adam | Adam <-- PERCEIVED IMAGE (3D)
/ \
/ \
/ \
Adam Adam Adam Adam <-- ACTUAL PICTURE (Flat, 2D)
/ \
/ \ <-- LINES OF SIGHT FROM EACH EYE
/ \
(*) (*) <-- EYES
The above graphic was crammed into 10 lines of text. If we moved the
eyes back (to a more realistic distance), the whole 3d image would
appear deeper, and not so spread out.
Cross-eyed viewing follows the same principles, but brings the focal point
up front of the picture and inverts the image. I'll use the same eyes and
picture, but move the eyes back for room to illustrate.
Adam Adam Adam Adam <-- ACTUAL PICTURE (Flat, 2D)
\ |
\|
Adam <-- PERCEIVED IMAGE (3D)
| \
| \
| \ <-- LINES OF SIGHT FROM EACH EYE
| \
(*) (*) <-- EYES
Now for the inverse part. Since the next two "Adams" are farther apart,
you must cross your eyes MORE (converge instead of diverge your eyes) to
get the "Adams" to overlap. This causes the next "Adam" in the image to
appear closer than the first one.
Adam Adam Adam Adam <-- ACTUAL PICTURE (Flat, 2D)
\ /
\ /
Adam\ / Adam <-- PERCEIVED IMAGE (3D)
Adam
/ \
/ \ <-- LINES OF SIGHT FROM EACH EYE
/ \
(*) (*) <-- EYES
Whew. Ascii graphics are a bit too tight to be very technical. By the
way, each letter (or pixel) in the 3D image comes from two letters in
the picture. Stereograms have blurry edges (right and left edges)
because the line of sight from the one eye passes through the picture,
but the line of sight from the other eye is off the picture. Examine
the wall-eyed example below.
Adam
Adam Adam <-- PERCEIVED IMAGE (3D)
\
\ \
\ \
\ Adam Adam Adam Adam <-- ACTUAL PICTURE (Flat, 2D)
\ \
\ \ <-- LINES OF SIGHT
\ \
(*) (*) <-- EYES
Here, the line of sight for the right eye goes through first "Adam"
in the picture, and the line of sight for the left eye is off the
picture. (Everything to the left of the first "Adam" in the IMAGE
is blurry.)
HOW TO GENERATE STEREOGRAMS
Random stereograms work the same way; they simple repeat random text or
pixels, instead of words like the "Adam" used above. Below, the pattern,
"ASDFGHJK", is repeated four times in each line. (I duplicated it for
easier viewing.)
ASDFGHJKASDFGHJKASDFGHJKASDFGHJK
ASDFGHJKASDFGHJKASDFGHJKASDFGHJK
ASDFGHJKASDFGHJKASDFGHJKASDFGHJK
As you might guess, the image consists of THREE repetitions of the
pattern, set back behind the picture (wall-eyed). To add some varying
depth to the image, we can simple add a space in the middle; or better,
we'll add a different letter, the letter Q. I've also dropped the K
off the end to keep it suitable for framing. :-)
ASDFGHJKASDFGHJKASDFGHJKASDFGHJK
ASDFGHJKASDFGHJKASQDFGHJKASDFGHJ
ASDFGHJKASDFGHJKASDFGHJKASDFGHJK
Adding the Q has the same effect as adding the space between "Adams"
in the previous example. Here it is again for comparison.
Adam Adam Adam Adam Adam Adam
Adam Adam Adam Adam Adam Ada
Adam Adam Adam Adam Adam Adam
These two stereograms demonstrate going down a level (deeper, for wall-
eyed viewers) by adding a new letter where you want to go down. The
image returns back to the original level because the added letter was
not repeated down the line; it was essentially deleted again. Hence,
deleting a letter causes the image to come forward one level. Lets
look at this by deleting a letter before adding any.
ASDFGHJKASDFGHJKASDFGHJKASDFGHJK
ASDFGHJKASDFGJKASDFGHJKASDFGHJKA
ASDFGHJKASDFGHJKASDFGHJKASDFGHJK
I deleted an H from the middle row, and added an A on the end to make
it flush again. This causes the image to come up a level where the H
was deleted, then go back down where the H returns to the pattern.
To fully control the ups and downs of stereogram generation, you simply
keep track of what's repeating and add and delete letters when needed.
For example, start with the pattern ASDFGHJK. If the input for the 3D
stereogram image is 00000000000011111222221111111110000, where the
numbers represent the levels of the 3D image, you simply delete a letter
from the pattern when you go up a level (0 to 1, or 1 to 2), and add a
letter to the pattern when you go down a level (2 to 1, or 1 to 0).
If you want to go up multiple levels, e.g., from level 1 to 3, delete
2 letters from your pattern. Adding two letters to the pattern likewise
causes a two-level drop in the image.
Start each line of the image by dumping the whole pattern. Recall that
in the examples above, four "Adams" in the picture creates three "Adams"
in the image. By dumping the pattern to start, we are simple providing
the first "Adam" to build the 3D image from. Now, we start building the
3D image.
ASDFGHJK
Since the first 12 levels are at level 0, we do no adding nor deleting;
just dump 12 more letters from the pattern in order.
ASDFGHJKASDFGHJKASDF
^image starts here
We now have our first transition, from level 0 to 1. Which letter do we
delete? Delete the next one in the pattern.
ASDFGHJK
^the next letter in the pattern
Since G is next, we delete it. Our new pattern is ASDFHJK, and H is the
next letter to be used in the image.
ASDFHJK
^the next letter to use in the image
Forget about the G. Consider it gone forever. The input now indicates
five letters at level 1. Since we made the transition to level one by
deleting the G, we simply copy the next 5 letters from the pattern into
the image. The next 5 letters in the pattern are HJKAS. (You've noticed
by now that we wrap around when we get to the end of the pattern.) I'll
lay the input next to our image to make it easier to see where we're at.

ASDFGHJKASDFGHJKASDFHJKAS

To jump up to level 2 from level 1, we delete the next letter in the
pattern, the letter D. The new pattern is shown below.
ASFHJK
^the next letter to use
We have 5 letters at level 2, so we copy the next 5 letters from the
pattern, FHJKA, to the image.

We must now move down a level, from 2 to 1, by ADDING a letter to our
pattern. Where do we add it? Add it as the next letter to use. Let's
add an X (randomly chosen letters work better than previously used
letters). Since A was the last letter used, S is the next to be used.
ASFHJK
^add X here
AXSFHJK
^next letter to use
Since there are nine letters at level 1, we must copy nine letters
from the pattern to the image (XSFHJKAXS).

to make it easier to view.

For each new line in the image, start with a new random pattern, and
follow the steps above. So, how are graphics stereograms made? The
same way, using colored pixel values for input. 3drandot uses RED as
the color deepest in the image, with GREEN in the middle, and BLUE as
the highest color.
The pseudocode below follows this algorithm. If you have any questions,
post them in the newsgroup. Let me know if you are interested in C code
that follows this algorithm. (The C code here in the FAQ follows a
different algorithm, the "lookback" algorithm.)
Enjoy!!

-----------------------------------------------------------------------
----- STEREOGRAM ALGORITHM --------------------------------------------
-----------------------------------------------------------------------
The following is an algorithm I developed for SIRDS generation. It is
functionally equivalent to the look back algorithms, without looking back.
It can be used for graphic stereograms, as well as the text stereograms.
It simply stores in PATTERN the values we would look back at. The input
file is depth data, or a z-buffer (see example input below). The levels
available in a picture are the maximum pattern size divided by two minus
one. Maximum pattern size should be equivalent to half the distance
between the eyes (for easy viewing), which is about 1 1/4 inches. So, for
typical text stereograms on an 80 char display, that's about 10 characters
for the maximum pattern size and 4 or 5 levels available. However, since
4 or 5 levels is unreasonable, we push the max pattern size to 16 (still
less that the 20 character distance between the eyes). This gives us about
7 or 8 levels.
If we do allow more than 7 levels when the max pattern size is 16, the
repeating pattern (of size max pattern - current level) grows so small that
four of them in a row (e.g., of size 7) would also create two double
patterns in a row (of size 14), causing floaties (aliasing).
I hope I'm making some sense. I'll try to spend some time rewriting this.
In addition, I'll integrate answers to any questions that come as a result
of this mess! In addition to the information here, we need to add a good
description of how they work (that is not covered here).
PL : Previous Level value
NL : Next Level value
INITIAL LEVEL SETTING
PL = 0
OPEN INPUT FILE FOR READING
WHILE NOT EOF (Y DIMENSION: FOR EACH LINE)
GENERATE NEW PATTERN
SET PATTERN PTR TO BEGINNING OF PATTERN
OUTPUT FULL PATTERN
WHILE NOT EOL (X DIMENSION: FOR EACH POSITION)
NL = NEXT INPUT LEVEL VALUE
IF NL != PL (IF WE'RE CHANGING LEVELS)
IF NL > PL (IF WE'RE MOVING UP)
DELETE NEXT NL-PL BITS IN PATTERN FROM PTR FORWARD
(IF GOING FROM LEVEL 0 TO 2, DELETE 2 BITS IN PATTERN)
ELSE (IF MOVING DOWN, AWAY)
INSERT PL-NL RANDOM BITS INTO PATTERN AT PTR POSITION
(IF GOING FROM LEVEL 3 TO 2, INSERT 1 BIT INTO PATTERN)
PL = NL (UPDATE PL)
OUTPUT NEXT VALUE IN PATTERN
ELSE
OUTPUT NEXT VALUE IN PATTERN
ADVANCE PATTERN PTR (CIRCULAR PATTERN)
ADVANCE INPUT PTR
(Redundancy exists to simplify readability.)
Assuming spaces translate to level 0, input like this (thanks, Dave
Thomas):

This uses 16 as the Max pattern size. Notice on the third line of the
output (the first line with level changes), the pattern is "7Z ... &{:".
When we go from level 0 to level 2, we lose two characters (i.e., ":.").
When we go from level 2 back to level 0, we insert two new characters
(i.e., "05" after the "osw5").
Any questions? Or better yet, what did I leave out?? I do hope this helps
someone!?!

Also from Dave Thomas:
Now here's a hack of a hack I found on the net. Basically it generates
stereograms from ascii diagrams. Here's the program first:
#define DEPTH0 16
#define COLS 79
#include <stdio.h>
main()
{
long now;
int col;
char m[COLS+1],s[COLS+1];
int i,e,c;
/* seed random number generator */
time (&now);
srand (now);
/* print fusion X's */
for (col = 0; COLS - col >= DEPTH0; col += DEPTH0)
{
for (i = 0; i < DEPTH0-1; ++i)
putchar (' ');
putchar ('X');
}
putchar ('\n');
/* process input image */
while (memset(m,'\0',COLS+1),fgets (m, COLS+1, stdin))
{
e = 0;
s[COLS] = 0;
for(i=0; i<COLS; )
{
e = 0;
while (i >= DEPTH0 && i < COLS &&
(c = m[i - DEPTH0]) >= '0' && c <= '9')
{
e = 1;
s[i] = s[i-DEPTH0+c-'0'];
++i;
}
s[i++] = (e || i < DEPTH0) ? randasc() : s[i-DEPTH0];
}
puts (s);
}
}
randasc()
{
/* large set of random characters */
return ('!'+rand()%92);
/* lowercase random letters */
/* return ('a'+rand()%26); */
}
Try passing it this file as the standard input:

----- HOPE FOR THE HOPELESS :-) ---------------------------------------
-----------------------------------------------------------------------
From: wchaga@vela.acs.oakland.edu (William C. Haga)
Being one who has used wide-eyed vision on chain link fences ever
since I was a kid, I was able to see the images in SIRDS right
away. But I've had difficulty explaining the technique to friends.
Today I had the latest Games magazine with me at my parents house.
Games is running another contest using SIRDS, so there are three in
the latest issue. This time I thought of the reflection idea. So I
opened mom's china cabinet, put the magazine against the glass in
the door, and told mom to keep looking at her own reflection in the
glass until the image appeared.
It took less than thirty seconds.
When she saw the 3d train engines, I was subjected to a squeal of
delight that I hadn't heard from her for a long time. "EEK! IT'S
COMING OUT AT ME! IS THIS EVER NEAT!". Dad tried for about a minute
but gave up.
About an hour later, mom and I heard a shout. We went to
the dining area, and there was dad with the magazine against the
glass in the door. "Isn't that just the most amazing thing!", said he.

----- COMMERCIAL SIRDS Posters ----------------------------------------
-----------------------------------------------------------------------
For those who do not have a local SIRDS distributor (i.e., the poster
cart at the mall), here are some companies you may be able to order from.
1)
The following posters are all certifiably cool with lots of great details,
and come in nice colors. They are (I believe) designed by NVision, or
something like that, and distributed here by Axis Corp.
Posters:
$25 Dinosaurs
$25 Discovery (Space shuttle and planet)
$25 Lady Liberty (U.S. Statue of Liberty)
$25 B-2 Stealth Bomber
$25 F-117 Bomber
$25 Nature's Majesty (Eagle with fish in talons, pine trees in bkgrd)
$30 Calypso Reef (Ocean Scene--new design, more detail)
Many more now, including small, $15 posters.
Axis Corp.

Salt Lake City, UT 84104 USA
(801)977-8816
Include US$5 for shipping and a poster tube. (The guy quoted me that price
for shipping to Australia.) Or, you can pay US$17 for a tube in a box.
Although they haven't had any problems shipping in the poster tubes, they
only guarantee safe delivery in a well-packed box.
And, by no means am I associated with these guys at all, except I spend a
lot of time enjoying their posters! (i.e., this is not an ad, but a
response to a request for SIRDS access.)
