Parallel projection facts for kids
The transformation P is the orthogonal projection onto the line m.
In linear algebra and functional analysis, a projection is a linear transformation P from a vector space to itself such that P2 = P. Projections map the whole vector space to a subspace and leave the points in that subspace unchanged.

A 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".

Comparison of several types of graphical projection. The presence of one or more 90° angles is usually a good indication that the perspective is oblique.
