Abstract

A continuous surface rendered monocularly by outline and surface contours is interpreted in three dimensions as having a definite shape in depth. A random dot stereogram of the same surface, devoid of monocular cues, usually conveys a more compelling 3-D impression of the surface. The natural viewing condition, of course, is a binocular projection containing redundantly consisent monocular cues.
