3D(1) For stereoscopic 3D concepts, see 3D visualization and 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. See 3D modeling, 3D animation and 3D graphics. Contrast with 2D.
