Quick questions on Perspective and proportion explained: N(A)-Level Art

In one-point perspective there is a single vanishing point. You use it when an object or scene faces you straight on. The front face stays flat, with truly vertical and horizontal edges, while the edges that run away from you all angle toward the one vanishing point and shrink as they go. A corridor or a straight road seen head-on is the classic case: the walls or kerbs seem to meet at a single point in the distance.

In two-point perspective there are two vanishing points, both on the horizon line. You use it when you see an object from a corner, like a building viewed from its edge. The vertical edges stay vertical, but the two sets of horizontal edges run off to two different vanishing points. This gives a more natural, three-dimensional view of boxes and buildings.

Perspective also keeps sizes believable: objects of the same real size must be drawn smaller the further back they are. A row of identical lamp posts should shrink steadily toward the vanishing point. Checking that distant things are smaller in the right amount keeps the depth convincing.

When an object faces you, its front edges stay vertical and horizontal; only the receding edges angle to the vanishing point.

Identical objects must shrink with distance. A far lamp post the same size as a near one kills the depth.
