3-D

3-D (3D) is a film that has a three-dimensional, stereoscopic form or appearance, giving a life-like illusion of depth.

It’s often achieved by viewers donning special red/blue (or green) or polarized lens glasses. This is when 3-D images are made interactive so that users feel involved with the scene.

The experience is called virtual reality. 3-D experienced a heyday in the early 1950s; aka 3D, three-D, Stereoscopic 3D, Natural Vision 3D, or three-dimensional.
