3D means three-dimensional, i.e. something that has width, height and depth (length). Our physical environment is three-dimensional and we move around in 3D every day. Humans are able to perceive the spatial relationship between objects just by looking at them because we have that perception, also known as depth perception. As we look around, the retina in each eye forms a two-dimensional image of our surroundings and our brain processes these two images into a three-dimensional visual experience.
People who can only see with one eye (monocular vision) can still perceive the world in three dimensions, and may even be unaware that they are stereo blind. They are simply missing one of the tools to see in 3D, so they rely on others without thinking about it.
In order to represent the 3D world on a flat (2D) surface such as a display screen, it's desirable to simulate as many of these perception tools as possible. Although there is currently no way to simulate all of them at the same time video does use a combination. For example, aerial perspective and size familiarity are automatically captured by the video camera. In CGI scenes, aerial perspective must be added so that distant objects appear less clearly (this is called distance fog).
Of course the addition of stereoscopic images (a separate image for each eye) is a significant improvement—so much so that most people think of stereoscopic films as being three-dimensional, and all others as being 2D.
