Orthographic projection (or orthogonal projection) is a means of representing a three-dimensional object in two dimensions.
Description
It is a form of parallel projection, where all the projection lines are orthogonal to the projection plane, resulting in every plane of the scene appearing in affine transformation on the viewing surface.
A lens providing an orthographic projection is known as an (object-space) telecentric lens.
The term orthographic is also sometimes reserved specifically for depictions of objects where the axis or plane of the object is also parallel with the projection plane, as in multiview orthographic projections.
