Good question, but I assume it's one that was already discussed and rejected
there that can handle refraction and true reflection in real time.
(I want to be wrong about that, so solione please let me know if I am).
(such as bump mapping, for example) would be worth having. Why? Because
I might want to write a VRML to POV translatar, for example, so that I
can tell my browser to save "snapshot" of the scene for later "developing"
with a raytracer.

on which OpenInventor is based. Of course, that shouldn't limit what
we specify in VRML, since VRML != OpenInventor.

but it's solithing like aR + bG + cB where a, b, and c sum to 1.00
and their ratio reflects the relative "importance" of each color.
