Abstract

This paper describes a technique for using a simple shading method, such as the Phong lighting model, to approximate the appearance calculated by a more accurate method. The results are then suitable for rapid display using existing graphics hardware and portable via standard graphics API's. Interactive walkthroughs of view-independent non-diffuse global illumination solutions are explored as the motivating application. You can get a pdf version of this paper here.
