Perspective 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.
