A Note on Shadows
Paul Haeberli
Oct 1994
Introduction
Shadows provide very important visual cues in the images
we see. They clearly show the physical relationship and
proximity of different objects. Rendering a 3D scene with shadows can
provide almost as much information as a pair of stereo images.
Carlos Castaneda had this to say about shadows in one of his
books about Don Juan.
Shadows
Don Juan pointed directly to a boulder in front of us.
"Look at the shadow of that boulder," he said. "The shadow is
the boulder, and yet it isn't. To observe the boulder in order
to know what the boulder is, is doing, but to observe its shadow
is not-doing."
"Shadows are like doors, the doors of not-doing. You may
say that there is movement in them, or you may say that the lines
of the world are shown in them, or you may say that feelings
come from them."
-Carlos Castaneda
