Vanishing Points and the View Point--2
Lines AB and CD (this time with A and C behind the projection plane) projected on XY plane: A'B and C'D.
Note: A'B not parallel to C'D.
Projectors from eye to A'B and C'D define two planes which meet in a line which contains the view point.
This line does intersect the projection plane.
Point of intersection is the vanishing point.
