How does Magic Eye illusion work?

The computer uses a Magic Eye algorithm that takes the image model and the pattern and arranges the repeating patterns to the necessary depth of the hidden image. When someone looks at a Magic Eye, the repeating pattern feeds the brain the depth information encoded into it, and the brain perceives the hidden picture.
