In computers, 3-D (three-dimensional) describes an image that provides the perception of depth in a two-dimensional space.

A 3-D image creation can be viewed as a three-phase process of tessellation, geometry, and rendering.

Popular products for creating 3-D effects include Extreme 3D, LightWave 3D, Ray Dream Studio, 3D Studio MAX, Softimage 3D, and Visual Reality. The Virtual Reality Modeling Language allows the creator to specify images and the rules for their display and interaction using textual language statements.
