....a stereoscope. It might seem that stereopsis necessarily requires two separate pictures, or at least some method of splitting a single picture into two to give each eye a separate view (using, for instance, red green filters, polarized light, or interference, as in holograms) Recently, however, Tyler and Clarke (1990) realized that a pair of random dot stereograms can be combined together, the result being called a single image random dot stereogram (SIRDS) or, more generally, an autostereogram. Essentially, one overlays the two separate random dot patterns, carefully placing the dots so that each one serves ....

....out that very convincing images with vivid depth can be constructed in this way, and the advantage of this ingenious approach is that no special viewing equipment is required. It does take a little practice to see depth in the pictures, but the experience is very satisfying when first achieved. Tyler and Clarke (1990) described a simple but asymmetric algorithm, which meant, for example, that some people can only see the intended effect when the picture is held upside down. This paper presents a new, simple, and symmetric algorithm for generating single image stereograms from any solid model. It also avoids ....
