THE VIEWPOINT IS
ALL-IMPORTANT…
1. 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.
2. 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.
3. A single line in the real world not parallel to the
window has a vanishing point.
