![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](/Images/godic/202502/01/Camera_focal_length_distance_house_animation1231.gif")

Parallel projections have lines of projection that are parallel both in reality and in the projection plane.
Parallel projection corresponds to a perspective projection with an infinite focal length (the distance from the image plane to the projection point), or "zoom".
