Diamond Ring

This diamond ring model was created by Dominic Ventura (dvent@earthlink.net) using the SDRC I-DEAS Master Series CAD modeler. It was imported into NuGraf via the STL converter where various lights and materials were assigned to the scene (red velvet for the background, silver for the ring and a carefully created refractive diamond material for the glass. The diamond was ray traced with the Fresnel algorithm which accurately simulates the correct amount of reflection from glass based on angle of incidence.
