3D is a motion picture that enhances the illusion of depth perception. Derived from stereoscopic photography, a special motion picture camera system is used to record the images as seen from two perspectives (or computer-generated imagery generates the two perspectives), and special projection hardware and/or eyewear are used to provide the illusion of depth when viewing the film.

3D technology takes us closer 3D films have existed in some form since the 1950s, but had been largely relegated to a niche in the motion picture industry because of the costly hardware and processes required to produce and display a 3-D film, and the lack of a standardized format for all segments of the entertainment business. 3-D films were prominently featured in the 1950s in American cinema, and later experienced a worldwide resurgence in the 1980s and '90s driven by IMAX high-end theatres and Disney themed-venues. 3-D films became more and more successful throughout 2000–10, culminating in the unprecedented success of 3-D presentations of Avatar in December 2009 and January 2010
