GeezerVison is showing mathworld.wolfram.com — Perspective -- from Wolfram MathWorld PerspectivePerspective is the art and mathematics of realistically depicting three-dimensional objects in a two-dimensional plane, sometimes called centric or natural perspective to distinguish it from bicentric perspective. The study of the projection of objects in a plane is called projective geometry. The principles of perspective drawing were elucidated by the Florentine architect F. Brunelleschi (1377-1446). These rules are summarized by Dixon (1991): 1. The horizon appears as a line. 2. Straight lines in space appear as straight lines in the image. 3. Sets of parallel lines meet at a vanishing point. 4. Lines parallel to the picture plane appear parallel and therefore have no vanishing point. There is a graphical method for selecting vanishing points so that a cube or box appears to have the correct dimensions (Dixon 1991).
