two point perspective definition

Two-point perspective is a type of linear perspective.  All categories of linear perspective include a horizon line and a stationary point (the position of the observer).  In two-point perspective, there exist two points from which an object’s lines radiate from; the sides of the object vanish to one of two vanishing points on the horizon line. An object’s vertical lines do not relate to the perspective rules of the horizontal lines.  By changing the vanishing points of the object, one can make increase or decrease the size of the object. Two-point perspective is the same as angular perspective.
