SIRDS FAQ: NEWBIES, READ ME
Todd D. Hale
it to say: run the generator in a Windows DOS box, get the SIRDS
on the screen, press ALT-PRTSCRN (copies current window to the
clipboard), paste into your favorite word processor or paint program,
and print!
We need an ftp site for the FAQ and all substantial SIRDS stuff!
Any ideas??
THE FAQ:
The following is just a bunch of info I've collected about SIRDS. It is not

----- C CODE TO GENERATE TEXT STEREOGRAMS -----------------------------
-----------------------------------------------------------------------
Also from Dave Thomas [slightly modified]:
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:
22222222222222222 11111111111111111111111
2222222222222222222 11111111111111111111111
22222222222222222222 11111111111111111111111

2222222222222222222 11111

You'll get output like this:

----- HOPE FOR THE HOPELESS :-) ---------------------------------------
-----------------------------------------------------------------------
From: wch...@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.
Later they were making jokes about teaching old dogs new tricks.

----- COMMERCIAL SIRDS Posters ----------------------------------------
-----------------------------------------------------------------------
From: th...@novell.com (Todd D. Hale)
For those who do not have a local SIRDS distributor (i.e., the poster
cart at the mall), here is one company you can order them from. 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.
Address:Axis Corp.
1732 S. 790 W.
Salt Lake City, UT 84104
USA
Phone: (801)977-8816
You must include $5 for shipping and a poster tube. (The guy quoted me
that price for shipping to Australia.) Or, you can pay $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.
Since I'm writing from the U.S., all currency mentioned here is in U.S.
dollars.
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.)
ANOTHER SUPPLIER:
Infix Technologies
PO Box 381
Orem, UT 84057-0381
(801) 221-9233
Shipping now:
18x24 Earth (mercator projection of the Earth's altitudes)
18x24 Salt Lake LDS Temple Centennial
Under development:
18x24 Beethoven (Oct 93)
(others are coming soon, too.)
Retail price for the 18x24 inch prints is $20 plus $3 s/h. Utah residents
add 6.25% sales tax. Wholesale and distributor discounts are available.
Quotes for custom work are also available. Cost and minimum order varies,
based on content.
