So we simulate point light sources by manipulating the normals of objects
in
relation to a parallel light source which is pretending to be a point light
source.
(I guess thats what you mean).

Hmmm....

While this works it is potentially processor intensive for complex scenes
and moving lights, plus you can't mix a point light source with a flat
light source.

Is there any other way of doing it, or do I have the totally wrong idea?

Thanks,
