Perspective Projection

See Linear Perspective for a discussion of one-point, two-point and three-point perspectives.

All perspectives on a planar surface have some degree of distortion, similar to the distortion created when portraying the earth's surface on a planar map. See Perspective Projection Distortion for a discussion.

The following terms are basic to understanding the drawing protocols of a perspective projection.

Perspective drawing for a painting. A photograph automatically shows a scene with correct perspective for the location of the camera. It follows that an artist wishing to paint a picture of the scene with true perspective needs only to draw an accurate copy of the photograph. If his painting is to be of a different size from that of the photograph he must accurately scale it up or down. This may easily be done by using a Proportional Divider, sometimes called a Variscaler, set to give the scaling ratio which is required to fit the scene on to his painting support
