  abstract =   "The paper introduces a method, called the albedo pumping-up,
               to derive new, physically plausible BRDFs from an existing
               one or from any symmetric function. This operation can be
               applied recursively by 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.",
