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.

WebCook-Torrance Reflectance Model. General form of the Cook-Torrance shading model: r = k a + ∑ i = 0 n l c ∗ ( n → ⋅ l →) ∗ ( d ∗ r d + s ∗ r s) s + d = 1. s in this equation is the metallic material property. Diffuse reflection is often modelled using Lambertian: r d = k d. There are other options, however, including Oren-Neyer.
