3-D

3-D or 3D abbreviates three-dimensional and is often related to a stereoscopic display that exploits binocular vision.

Three-dimensional objects have volume and may be measured and described using three orthogonal directions.

In animation, 3-D sometimes refers to shaded, modeled shapes that have an appearance of depth, as opposed to the "flat" rendering of conventional cel animation. An example of this was seen in a particular episode of the animated video cartoon The Simpsons, where Homer escapes his flatland-like world and enters a universe of higher dimensionality. The figure renderings and visual effects in this episode were accomplished using 3D computer graphics.

In literary criticism rounded three dimensional characters are contrasted to cardboard cutouts.
