	Stereogram - Wikipedia, the free encyclopedia
		A stereogram is an optical illusion of depth usually observed by allowing the eyes to focus behind an image (diverge), but also sometimes in front of the image (converge).
		Stereograms had been created for years before being re-popularized by the creation of random-dot stereograms on computers.
		Stereograms cards are frequently used by orthoptists and vision therapists in the treatment of many binocular vision and accommodative disorders [1].

	Stereograms and Teaching Mathematics (Site not responding. Last check: 2007-10-08)
		In a stereogram (like in a hologram, which is much more expensive and difficult to produce), we can actually see a curve or a surface embedded in $\RR^3$, and not only its projection onto a plane.
		On the other hand, every stereogram is a kind of a puzzle, and for a student (or anybody else) who is attracted to solving puzzles, they will represent a challenge, and even entertainment.
		Our suggestion is, to make stereograms of mathematical constructions available to students (where they could be helpful) as an optional additional possibility, some students will find them useful and amusing and will use them, others will avoid them and use other means for visualization and better understanding.

	First repeating-stripe random dot stereogram
		This stereogram has six repetitions of the pattern and is designed to give a radically different image at the second degree of eye cross (or spread) than it does at the first.
		This stereogram was was tediously typed on a typewriter.
		The purpose of this stereogram was to illustrate a kind of "fourth dimension" in a visual object.

		We hypothesized that giving one group accurate information about what they should see in the upcoming stereogram would have a significant facilitatory effect on the average time taken to perceive the three-dimensional pop-out image.
		Group 1, those given no indication what they were viewing in the stereogram, had a mean reaction time of 8.5605 seconds and a median of 6.9000 seconds.
		Group 2, those told what they were viewing in the stereogram, had a mean reaction time of 5.5514 seconds and a median of 3.6000 seconds.

	Seeing 3D: Stereographic Carpeting? (Site not responding. Last check: 2007-10-08)
		The first step to viewing a stereogram is to have stereo vision-in other words, two eyes that function as a team (1).
		This is probably because those people are unable to perfect the viewing technique-most stereograms are drawn so that in order to see the hidden image, you have to focus your eyes on a point about twice as far away from you as the picture itself.
		Another way of focusing on stereogram pictures is "cross viewing," in which the lines of sight of the eyes are crossed about halfway between the viewer and the picture.

		You may change program settings including interocular distance, desired viewing distance, coding pattern scaling factor, stereogram size, resolution of display media, background distance, etc. And the settings are remembered when the program starts next time.
		To create a stereogram hardcopy, it is recommended to print the stereogram directly from Stereogram Maker.

	Stereogram Software > Make a Stereogram on Mac and PC
		During the 1960s, a stereogram researcher named Bela Julesz was the first to use computer-generated 3-D images made up of randomly placed dots to study depth perception in human beings.
		In the years that followed, other people continued using random dot stereogram pictures in their work; many of them were graduate students who studied with Julesz.
		Since Julesz, in 1960, was the first to employ a computer to generate random dot stereograms, many would consider him the person most responsible for their popularity today....

	Software for Creation Stereograms / SIRDS / Hollusion - Stereogram FAQ
		Most Stereogram pictures are usually generated so that if you look at (converge your eyes on) a position twice as far away as the picture, and focus on the picture, generally after a few minutes you see a surprising 3D image!
		In a "normal" stereogram the constraints are only in the horizontal direction, but by assigning constraints in 2-dimensions instead of linearly across the image, it is possible.
		To see a stereogram you must converge your eyes in such a fashion that each eye is looking at the corresponding pixel/dot required to get the 3D effect.

	[ The Sunny Spot ] ASCII-Art - Single Image Random Dot Stereogram (Site not responding. Last check: 2007-10-08)
		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.
		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 is the kind of autostereogram where a hidden image appears within a random pattern of dots, either fl and white, monotone, or multicolored.
		If you've ever wondered about the peculiar sharpness possessed by stereograms, it is because the deepest and highest planes of the image are all in focus at once.
		Not only do some shaped stereogram elements retain a sense of volume, but using subtle manipulations is more like sculpting than the usual folding.

		I prefer crosseyed stereograms because they can be larger, thus more detailed (matters more in the digital realm), and requires no extra gear to view.
