What is the purpose of drawing in one point perspective?

One point perspective is a drawing method that shows how things appear to get smaller as they get further away, converging towards a single ‘vanishing point’ on the horizon line. It is a way of drawing objects upon a flat piece of paper (or other drawing surface) so that they look three-dimensional and realistic.

How do you explain perspective drawing?

Perspective drawing is a technique used to depict spatial depth, or perspective. In other words, it allows you to accurately draw a three dimensional object onto a two dimensional plane. There are typically three types of perspective drawing: one-point perspective, two-point perspective, and three-point perspective.
