Vanishing point of multipoint perspective, and historian Kirsti Andersen compiled these observations. She notes, in terms of projective geometry, the vanishing point is the image of the point at infinity associated with , as the sightline from through the vanishing point is parallel to . As a vanishing point originates in a line, so a vanishing line originates in a plane that is not parallel to the picture . Given the eye point , and the plane parallel to and lying on , then the vanishing line of is . For example, when is the ground plane and is the horizon plane,
The Parallel was sent out in. Gaines is summoned to examine the capsule, but when he approaches it he is gradually returned to the point at which he left his own universe. He lands his craft safely and reports what happened to his superiors. They are prepared to write it off as a nightmare, but controllers on the ground subsequently receive another transmission—from "Colonel" Robert Gaines. The transmission cuts out a few seconds later, and the Colonel disappears from radar. The Major returns home and happily confirms that his daughter now recognizes him and the white picket fence is absent. The Parallel
