Neither digital 2D animation nor traditional 2D animation has a change in perspective right?

No matter how strong the three-dimensionality of the picture is in two-dimensional animation, it only simulates three-dimensional effects in two-dimensional space, and only the position of the objects in the same picture moves and changes shape, without the change of perspective.

Two-dimensional is in a plane of content, two-dimensional that is, left and right, before and after the two directions, there is no up and down. The content on a piece of paper can be seen as two-dimensional. That is, there is only area, no volume. Two-dimensional is a kind of plane technology, such as ordinary plane animation, called two-dimensional animation, referred to as two-dimensional.
