What is Plane?

Plane is a three-dimensional geometric object that can be thought of as a flat surface that extends infinitely in all directions. In other words, a plane is an infinite sheet of paper with no thickness. While this may seem like a strange concept, it’s actually a very useful one in mathematics and physics.

In the field of 3D visualization, planes are often used to represent objects or surfaces. For example, when you look at a building from the outside, you are seeing its facade (a two-dimensional surface) as a plane. Similarly, when you look at a table top from above, you are seeing the top surface of the table as a plane.
