Document Summary

The visual world provides many different sources of information about tridimensional spaces, depth cues. There is a body of research trying to explain the ways the visual system processes depth cue information to provide an accurate perception of space. Experimental evidence shows that several depth cues are involved and weighted differently for different perception tasks. Monocular static: linear perspective, size gradient, occlusion, depth of focus, cast shadows. The geometry of linear perspective is obtained by sending a ray from each point in the environment space perception and the display of data in space 261 through a picture plane to a single fixed point. Each point on the picture plane is coloured according to the light emanated from the corresponding region of the environment. The resulting objects vary in size on the picture plane in inverse proportion to their distance from the fixed point. If an image is created according to this principle, the correct viewpoint is determined by similar triangles.
