What's the difference between 2D and 3D animation?

The word dimension is a basic concept in geometry and space theory. Every element that constitutes a space, such as length, width and height, is called a dimension. Two-dimensional space refers to a plane space composed of two elements: length and width (X axis and Y axis in geometry). Three-dimensional space refers to a three-dimensional space composed of three elements: length, width and height (X axis, Y axis and Z axis in geometry). At present, there is no clear conclusion about the definition of two-dimensional animation and three-dimensional animation, because the existing animation playback forms are projected on a plane or surface, and the real three-dimensional display technology is not used. What we usually call "two-dimensional animation" and "three-dimensional animation" refer to the creative space of animation. Two-dimensional animation and three-dimensional animation are divided according to whether the camera or virtual camera can rotate at will during the production process. Two-dimensional animation includes traditional hand-drawn animation, two-dimensional software animation and plane material animation, and three-dimensional animation includes three-dimensional material animation and three-dimensional software animation. With the popularization of computer technology, more and more animations are made by computer technology, and there are many kinds of software.

Two-dimensional animation software mainly includes ANIMO, RETASPRO, TOONZ, Flash, TOOBBOOM and so on. Three-dimensional animation software mainly includes Maya, SoftimageXSI, 3dsmax, LightWave, Houdini, CINEMA4D and so on. Apart from the differences between 2D animation and 3D animation according to whether the camera or virtual camera can rotate at will, mainstream 2D animation (excluding plane material animation) and 3D animation (excluding 3D material animation) mainly have the following differences: the production process is different: it is caused by different production methods. Two-dimensional animation: script writing → role and scene setting → color design and color distribution → lens script design → early dubbing → storyboard production → design sketch drawing → background drawing → original painting → animation drawing → coloring → special effects production → photo film filling → shooting → dubbing soundtrack → final output. Three-dimensional animation: writing a script → setting roles and scenes → designing story board → pre-dubbing → making storyboards → making models → drawing textures → setting material lighting → making animations → making special effects → adjusting material lighting → layered rendering output → post-synthesis → dubbing soundtrack → final output.
