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

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
