What's the difference between traditional animation and computer animation?

Animation was invented before film, and it came into being in19th century. The first animation device was invented by an Englishman in 1820. It is tied to both ends of a disk with pictures on both sides with a rope. When the disc rotates around the central axis of the rope, you can see the dynamic effect of the fusion of two pictures. A real animation device consists of a slit and a turntable. There are small pictures on the turntable, and each picture is a frame. When the disc rotates at a faster speed, the effect of complete action can be seen from the slit. Film animation was born in 1902. The animation at this stage is called traditional animation.

(2) Computer animation.

Computer animation refers to the animation made by computer image processing technology. Computer animation is mainly divided into two categories: 2D animation and 3D animation.

Two-dimensional animation is based on two-dimensional plane animation, also known as computer-aided animation. Its basic production process is: hand-drawn pictures are input into the computer frame by frame, and the computer completes drawing and coloring, and then the computer controls the recording of animation. The advantages of two-dimensional animation are as follows: the interpolation rules of key frames and frames are given, and the intermediate picture can be calculated by computer; Easy to color and modify. However, the disadvantage is that computers can only play an auxiliary role and cannot replace the initial picture generation of creativity.

Three-dimensional animation is an animation based on three-dimensional space, also known as computer-generated animation. The basic production process is as follows: first, create 3D data of animated characters and scenes to generate object shapes, then give these shapes materials and maps, and make the characters move in 3D space through interpolation calculation; Then set virtual lights and cameras in the scene and render them; Finally, a complete animation is generated by synthesizing the sequence.
