Magiceye
is the commercial brand name that popularized single-image random-dot autostereograms (SIRDS) in the 1990s. These optical illusions allow viewers to perceive hidden three-dimensional scenes within a repeating two-dimensional pattern without the need for specialized 3D glasses. This paper explores the fascinating intersection of human neurobiology, binocular vision, and computer science that makes these illusions possible. We detail the history of stereopsis research, break down the physical geometry behind the viewing techniques, and present the algorithmic steps required to generate an original autostereogram. 1. Introduction to Stereopsis
Iterate through the image from left to right. For each pixel at position , calculate its required shift based on the depth map value. You then force the color at to be identical to the color at Step 4: Smooth the Output Because a pixel at position MAGICEYE
across the image, pixel by pixel, a smooth gradient of virtual depth is rendered. 4. Algorithmic Steps to Create an Autostereogram is the commercial brand name that popularized single-image
