Using the rules of perception to create an illusion of depth is only one style of painting. In both medieval and modern paintings in Western art tradition, for instances, artists have presented their subjects without this, in a much flatter, unnaturalistic or unrealistic manner.

But let's bounce the in-depth analysis of perspective and the use of the picture plane, to rather focus on my key point: using perspective to create an illusion of depth in a painting is but one option available to you. You don't have to divide a painting into a foreground, middle ground, and background if you don't want to. You can adapt and change it as you like.

In these optical illusions, the brain interprets what the eye sees in a way that differs from measurable certainity.
