Hi
I'm a student just learning VRML, and I had soli questions about the Material
field in VRML 1.0 as described in the spec. -
hope soli of the more experienced user of VRML can help me:
1. How would one model essractive index and reflectivity of a material
2. Why is the transparency defined as a single float - whereas normally
one has an RGB triplet representing the transparency of the material
to each of those colors. How can one convert between an RGB triplet
representation and a single index as VRML requires ?
And finally : why isn't there a VRML newsgroup ?
Thanks for your help
