How do 3D eye illusions 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.

How do those 3D images work?

3D imaging relies on stereography, which we can observe from a familiar source: The human vision system. Humans see things with two eyes set slightly apart. … Two lenses are used in every 3D shot – each captures an image slightly offset from the other. As a result, 3D images contain twice as much information as 2D ones.
