Reflectance models by pumping up the albedo function

Neumann L., Neumann A., Szirmay-Kalos L.

Machine Graphics and Vision

1999

Vol. 8, No. 1

3-17

The paper introduces a method, called the albedo pumping-up, to derive new, physically plausible BRDFs from an axisting one or from any symmetric function. This operation can be applied recursively arbitrary number of times. An important application of this operation is the transformation of the Phong and Blinn models in order to make them produce metallic effects. The paper also examines the albedo function of reflectance models and comes to the conclusion that widely used models violate energy balance at grazing angles.
