Stereogram

Illustration for Stereogram in low resolution Illustration for Stereogram

Autostereograms (aka Magic Eye images) were very popular in the '90s. They look random, but actually contain a detailed 3D scene, which can only be seen by looking at the image a certain way. Such images work by using repeated patterns to trick the brain into seeing depth.

This project can generate such images. It runs on GPU and handles moving scenes.
