How to Add Coating and Scattering Functions to Non-Sequential Objects

no@spam.com (Mark Nicholson) — Mon, 03 Apr 2006 00:00:00 PDT

Non-sequential objects are 3D volumes. Thin-film coatings, and scattering functions, are surface properties of these 3D volumes. This article explains:

The concept of the "face number" of an object
How thin-film coatings and scattering functions are applied to the various faces of an object
Special issues involved in applying these properties to CAD objects
