is at finite distance


is at infinite distance


is at same distance of actual object


is near than the actual object

Detailed explanation1: It is an arbitrary point from where the lines are drawn on each point of an object. If the cop is located at infinity, all the lines are parallel and the result is a parallel projection.
Detailed explanation2: In Perspective Projection the center of projection is at finite distance from projection plane. This projection produces realistic views but does not preserve relative proportions of an object dimensions.
Detailed explanation3: If the distance between the Centre of Projection (COP) to the projection plane is finite, the projectors are not parallel to each other. This kind of projections is called perspective projection.
Detailed explanation4: Orthographic Projection: Observer at infinite distance from the object.
Detailed explanation5: In threedimensional geometry, a parallel projection (or axonometric projection) is a projection of an object in threedimensional space onto a fixed plane, known as the projection plane or image plane, where the rays, known as lines of sight or projection lines, are parallel to each other.
