Question

Aside from the number of vanishing points, what is the difference between a one-point, two-point, and three-point perspective sketch? *

Answer 1

• Three point perspective is great when you wish to render objects or scenes from an abnormally high or low point of view. The distortions that the third vanishing point brings into your composition often has a very artistic effect and makes even the most simple concept more interesting.
• 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.
• The one-point perspective is used to provide a sense of depth to a drawing, as images in the foreground are bigger and appear to be closer than the smaller images in the background.

Answer 2

The correct answer to this open question is the following.

Aside from the number of vanishing points, the difference between a one-point, two-point, and three-point perspective sketch is that these sketches are going to vary in the different points of view they have. What happens is that the vanishing point is the reason why this effect is caused. Let's remember that the vanishing point is the point where parallel lines that are moving away, meet.
