How do stereograms work?
A depth map defines the shape, while a texture supplies repeating details. The generator changes their horizontal spacing according to depth. When your eyes fuse the corresponding patterns, the flat image can reveal a hidden 3D shape.
Stereogram or autostereogram?
A stereogram is the broader category, which also includes pairs of images for the left and right eyes. An autostereogram encodes depth in repeating patterns within one image. The examples here use that single-image form, with a depth map you can inspect alongside the result.

Start with the viewing mode chosen for the image. These examples use parallel viewing: relax your gaze as if looking beyond the picture and try to fuse the repeating pattern. Cross-eyed images use a different focus direction; the two methods are not interchangeable.
Stereograms can work on a computer screen. Open the full-size result to inspect its detail: thumbnails are useful for browsing, but scaling changes the spacing of the pattern and may change the viewing experience.
