Anaglyph images are used to provide a stereoscopic 3D effect, when viewed with 2 colour glasses (each lens a chromatically opposite colour, usually red and cyan).
Images are made up of two colour layers, superimposed, but offset with respect to each other to produce a depth effect.
When viewed through the "colour coded" "anaglyh glasses", they reveal an integrated stereoscopic image. The visual cortex of the brain fuses this into perception of a three dimensional scene or composition. Video games, theatrical films, and DVDs can be shown in the anaglyph 3D process including photos.
In fact this is one of the oldest and best known 3D technologies that are still commonly used nowadays and is a very inexpensive technology. Most often, prolonged visualisation through the filter glasses could cause some unpleasant feeling to some people. The first method to produce anaglyph images was developed 1853 by Wilhelm Rollmann, a German, in Leipzig.
Anaglyph glasses comes with 3D DVD movies such as "SPY KIDS 3D GAME OVER".
