3D rendering.
(2) (
3Dimensional) Objects that are rendered visually on paper, film or on screen in three planes representing width, height and depth (X, Y and Z). In the computer, a 2D drawing program can be used to illustrate a 3D object; however, in order to interactively rotate an object in all axes, it must be created as a 3D drawing in a 3D drawing program.

3D animation and
