Traditional 2D and 3D animation

One dimension actually refers to a line, which is understood as the left and right direction (such as time). It can also be understood as a point moving into the line, which refers to an object without area and volume.

Two-dimensional is a kind of plane technology, such as ordinary plane animation, which is called two-dimensional animation. Three-dimensional is three-dimensional. In the study of mathematics and physics, one dimension is too simple and three dimensions are too complicated. The two-dimensional "plain" just gives researchers enough space to play their talents. But two-dimensional is not only a virtual space on draft paper, but also has great value in reality.

Three-dimensional animation, also known as 3D animation, is a new technology with the development of computer software and hardware technology in recent years.
