What is anaglyph?

anaglyph meaning in Information Science terminology / glossary / dictionary is:
A composite stereographic image produced by printing the same image twice, in complementary colors slightly displaced laterally, rather than superimposed exactly. In cartography, red is normally used for the right component and green or blue for the left. Although the image appears to be out of register when seen with the naked eye, a three-dimensional effect is produced by viewing it through a pair of eyeglasses equipped with filters of corresponding colors.
