WebThe BRDF (Bidirectional Reflectance Distribution Function) gives the reflectance of a target as a function of illumination geometry and viewing geometry. The BRDF depends on wavelength and is determined by the structural and optical properties of the surface, such as shadow-casting, multiple scattering, mutual shadowing, transmission, reflection, … WebA BRDF, bi-directional reflectance distribution function, is a tool for describing the distribution of reflected light at a surface. Given an incoming light ray at a point on a surface, the BRDF is used to calculate how much …

Note that while the BRDF is constant, there is a cosine falloﬀ of intensity toward graz-ing incident angles with respect to the light source. While not physically realizable, the Lambertian surface is often a good ﬁrst-order approximation and is a widely used foxy symbol
