Linear or point-projection perspective (from Latin perspicere 'to see
through') is one of two types of graphical projection perspective in the
graphic arts; the other is parallel projection. Linear perspective is an
approximate representation, generally on a flat surface, of an image as it is
seen by the eye. Perspective drawing is useful for representing a three-
dimensional scene in a two-dimensional medium, like paper.
The most characteristic features of linear perspective are that objects appear
smaller as their distance from the observer increases, and that they are
subject to foreshortening , meaning that an object's dimensions along the
line of sight appear shorter than its dimensions across the line of sight.
