Perspective (graphical)

Graphical perspective attempts to approximate on a planar surface an image as it is perceived by the eye. An exact replication is only possible on a spherical surface. (See perspective projection distortion.)

This approximation is either executed intuitively by freehand sketching or else by employing certain geometric protocols with drawing instruments. In the former case it is generally referred to as artistic, spatial foreshortening; in the latter case it is referred to as perspective projection or if calculated using matrix multiplication (usually by a computer) as a perspective transform.
