Difference Between Parallel Projection Perspective Projection

Definition : perspective projection

If COP[ Centre Of Projection] is located at a finite point in 3 space , the result is a perspective projection.

Definition : Parallel projection

If COP [ Centre Of Projection] is located at infinity, all the projectors are parallel and the result is a parallel projection.

less realistic view.Coordinate are transferred to viewing plane along parallel lines. Preserves Relative size of object’s portions.

PERSPECTIVE PROJECTION

visual effect is similar to human visual system.Projection lines converge in a point behind viewing plane. Doesn’t preserve relative size but looks more realistic.
