Perspective (graphical)

Form of graphical projection where the projection lines converge to one or more points

Perspective (from Latin perspicere 'to see through') is the representation of objects on the basis of how they may appear in real-life. Perspective is an approximate representation, generally on a flat surface, of an object as it is seen by the eye. Perspective is useful for representing a three-dimensional scene in a two-dimensional medium, like paper.
