Paper Abstract

The bidirectional reflectance distribution function (BRDF) for a surface is an important quantity in simulation and prediction of ultraviolet, visible and infrared signatures from objects. In this paper we briefly give some background for modelling of rough surface scattering and present a selection of models for scattering of light from rough surfaces. Emphasis is placed on some analytical (approximate), physics-based methods, through which the BRDF can be calculated from surface topography and material optical data. Ranges of validity and limitations of the models are discussed. We also touch upon the relation between these analytical models and some more empirical, parametric, models for BRDF which are sometimes used in computer programs for three-dimensional visualization and scene simulation. Some examples from calculations using rough surface scattering models are presented.
