3D animation

3D computer graphics 
are graphics that use a three-dimensional (3d animation) representation of geometric data, that is stored in the computer for the purposes of performing calculations and rendering 2D images. Such images may be stored for viewing later or displayed in real-time.

Despite these differences, 3D computer graphics rely on many of the same algorithms, as 2D (flash) computer vector graphics in the wire-frame model and 2D computer raster graphics in the final rendered display. 

3D computer graphics  (3d animation) are often referred to as 3D models. Apart from the rendered graphic, the model is contained within the graphical data file. . A 3D model is the mathematical representation of any three-dimensional object. A model is not technically a graphic until it is displayed. 

This is all about 3D animation
