Graphical projection Perspective projection is a linear projection where three dimensional objects are projected on a "picture plane". This has the effect that distant objects appear smaller than nearer objects. It also means that lines which are parallel in nature (that is, meet at the point at infinity) appear to intersect in the projected image, for example if railways are pictured with perspective projection, they appear to converge towards a single point, called vanishing point. Photographic lenses and the human eye work in the same way, therefore perspective projection looks most realistic. Perspective projection is usually categorized into "one-point", "two-point" and "three-point
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 Major returns home and happily confirms that his daughter now recognizes him and the white picket fence is absent. The Parallel
