AAAAhhh. I see where the question is coming from, now. Those numbers are based on real-world numbers called the Index of Refraction, which is pretty unique for almost all subtances. A complete discussion of the mathematics can be found at: http://www.rockhounds.com/rockshop/gem_designs/refractive_index/ And a listing of the most common RI's for various transparent materials at, (as well as a Bryce rendered set of pics showing the effects of those settings): http://www.3dlapidary.com/HTML/Materials3.htm (You happened to hit one of my hobby points with this: I run 3D Lapidary.com -- in my sarcasm alert abundant free time.)
