Once upon a time I was cerious about Non Photorealistic Rendering (NPR,
or better known as Cel-shading or Toon-shading) in Povray. I was pointed
to some nice examples that used a three-pass system of lighting and edge
detection. I was wondering where I can find that example again and if it
has been improved any? Any help will be... umm... helpful.
