Cartoons use the principle of "what" to make static pictures called natural and continuous dynamic pictures.

Animation is a picture that decomposes the expressions, movements and changes of characters into frames of many moments of action, and then continuously shoots a series of pictures with a camera, resulting in continuous changes in vision.

its basic principle, like movies and television, is the principle of visual persistence. Medicine has proved that human beings have the characteristic of "visual persistence". After seeing a painting or an object, people's eyes will not disappear within .34 seconds. Using this principle, playing the next painting before it disappears will give people a smooth visual change effect.

there are the following categories of animation. According to the technology, it can be divided into plane hand-drawn animation, three-dimensional shooting animation, virtual generation animation, and real-life animation. According to the media, it can be divided into cinema animation, TV animation, advertising animation, science and education animation, and according to the nature of animation, it can be divided into commercial animation and experimental animation.
