is the interpupillary distance of the viewer. By slightly varying the repetition width

: At Bell Labs, neuroscientist Béla Julesz invented the Random-Dot Stereogram (RDS) . He proved that depth perception occurs in the brain, not the eyes, by generating two separate random dot patterns that formed a 3D shape only when viewed through a stereoscope. MAGICEYE

be the horizontal repetition width of the background pattern. is the interpupillary distance of the viewer

: Hold the center of the image right up to your face until it becomes completely blurry. Without blinking or trying to focus, slowly move the image away. Your eyes will naturally attempt to maintain their unfocused state, locking onto the hidden 3D plane as it pulls into perspective. be the horizontal repetition width of the background pattern

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

Generating a custom Magic Eye image requires a base background pattern and a corresponding "depth map" (a grayscale image where white represents the foreground and black represents the background). Step 1: Initialize the Canvas
