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.
