Anaglyph is a picture that can be used to create a stereoscopic image.'Stereopsis' (originally) means solid sight and refers to the multitude of sources of information that may be used to determine the structure and layout of the three-dimensional world.A picture with diffrent colours can be presented to each eye because Anaglyph uses two colours with corresponding colour filters which is in practice red and green, or sometimes red and blue.
