The definition of the '''BSDF''' ('''Bidirectionalbidirectional scattering distribution function''') is not well standardized. The term was probably introduced in 1980 by Bartell, Dereniak, and Wolfe.<ref name=bartell1980>{{cite web

</ref> Most often it is used to name the general mathematical function which describes the way in which the light is scattered by a surface. However in practice this phenomenon is usually split into the reflected and transmitted components, which are then treated separately as '''BRDF''' ('''[[Bidirectionalbidirectional reflectance distribution function]]''') and '''BTDF''' ('''Bidirectionalbidirectional transmittance distribution function''').
