Diffuse lighting

From Tech Artists Wiki

Diffuse lighting (also called Lambertian), is light that is diffused on a surface. It is a component of direct lighting, specular lighting and sub-surface scattering being the others. Diffuse lighting has fewer variations and shading models than specular- generally diffuse is the dot product of the normal and light vectors, often times used to lookup along a curve for non-linear lighting. Generally, the rougher a surface, the higher the diffuse component (and lower the specular component).
