PERSPECTIVE GEOMETRY
DUE-1140113 (SU)DUE-1140135 (F&M)
THE VIEWPOINTS PROJECT2000–2008

THE VIEWPOINT ISALL-IMPORTANT…
If a collection of parallel lines in the real world is parallel to the window (picture plane), then their images on the window are parallel.
If a collection of parallel lines in the real world is NOT parallel to the window, then their images on the window meet at a common point, which we call the vanishing point.
A single line in the real world not parallel to the window has a vanishing point.
