Detailed explanation-1: -A vanishing point is a point on the image plane of a perspective rendering where the two-dimensional perspective projections of mutually parallel lines in three-dimensional space appear to converge.
Detailed explanation-2: -Definition. Center of projection is a single 3D point in space where all the light rays sampled by a conventional pinhole camera intersect.
Detailed explanation-3: -Center of Projection – It is a point where lines or projection that are not parallel to projection plane appear to meet.
Detailed explanation-4: -In a perspective projection, the center of projection is at a finite distance from the viewing plane. Parallel lines that are not parallel to the viewing plane, converge to a vanishing point. – A vanishing point is the projection of a point at infinity. There are infinitely many general vanishing points.
Detailed explanation-5: -The edges of objects appear to converge or taper as they recede in the distance to a common point on the eye level or horizon line. In Linear Perspective this is referred to as a Vanishing Point.
