anaglyph
[map display] A stereo image made by superimposing two images of the same area. The images are displayed in complementary colors, usually red and blue or green.
Anaglyphic stereoplotters pass each image through separate colored filters (red and blue-green) so that both images can be displayed on a single monitor. The operator is required to wear special colored glasses to view the 3 dimensional image.
Anaglyph images have seen a recent resurgence due to the presentation of images on the internet.
For black and white photos, we do this by the anaglyph method, in which we project one photo through a red filter and the other a cyan filter and then view them through eyeglasses with corresponding color filters.
The apparent shift in an object's position when it is viewed from two different angles. Referenced by: Anaglyph image; Celestial pole; Declination; Celestial sphere; Alidade; Aliasing; Triangulation; Orthophoto; Analytical Stereoplotter.
