A method is presented that takes as an input a 2D microfacet orientation distribution and produces a 4D bidirectional reflectance distribution function (BRDF). This method differs from previous microfacet-based BRDF models in that it uses a simple shadowing term which allows it to handle very general microfacet distributions while maintaining reciprocity and energy conservation. The generator is shown on a variety of material types.

• A physically-based model for retrieving foliar biochemistry and leaf orientation using close-range imaging spectroscopy (2016, neutral): “…composed of an upper wax layer and a bottom leaf mesophyll layer), one should also consider the fraction of light that is re fl ected by the fi rst wax layer and that does not reach the bottom layer (Ashikmin, Premo ž e, & Shirley, 2000; Stuckens, Somers, Delalieux, Verstraeten, & Coppin, 2009).”
