A projection plane, or plane of projection, is a type of view in which graphical projections from an object intersect.

With perspective drawing, the lines of sight, or projection lines, between an object and a picture plane return to a vanishing point and are not parallel. With parallel projection the lines of sight from the object to the projection plane are parallel.

  Simulated rays of light travel from the object, through the projection plane, and to the viewer's eye or camera. This is the basis for graphical perspective.
