3D projection

A 3D projection is a way of showing a three-dimensional environment on a two-dimensional flat surface or screen.

A projection is usually calculated using complex mathematical equations.

  Parallel projection corresponds to a perspective projection with a hypothetical viewpoint; i.e. one where the camera lies an infinite distance away from the object and has an infinite focal length, or "zoom".
