Orthographic projection is a means of representing a three-dimensional (3D) object in two dimensions (2D).
It is a form of parallel projection, where the view direction is orthogonal to the projection plane. It is further divided into multiview orthographic projections and axonometric projections.
Orthographic projection corresponds to a perspective projection with a hypothetical viewpoint; e.g., one where the camera lies at an infinite distance away from the object and has an infinite focal length, or "zoom".
