WebResearchers have proposed many BRDF models to describe different scenes. One of the classical models is the Cook-Torrance model , which assumes that the surface of the medium is composed of a series of plane elements whose direction vectors satisfy Gaussian distribution. The Cook-Torrance model can be expressed as http://www.tc.faa.gov/its/worldpac/techrpt/ac65-13w.pdf WebThe BRDF. The Cook-Torrance BRDF consists of two terms, a diffuse Lambert term and a specular Cook-Torrance term f(l,v) = k d f lambert + k s f cook-torrance. The coefficients k d and k s have to add up to 1 to obey the law of conservation of energy. Here the coefficents are vectors, so they have to add up 1 componentwise. Diffuse Term dont starve rawling

The multiplication by $2\pi$ at the end, then, can be seen as the division by the pdf, factored out of the sum because it's constant. The constant pdf is $1/2\pi$ (as opposed to some other number ...
