Diffuse reflection is a mode of light behavior obeying Lambert's Law. This law states that light striking a surface is scattered with equal intensity in all directions, with an intensity that is proportional to the angle of the incident light. Generally this is not sufficient to model how most materials appear when illuminated by a particular light source. Rather a diffuse term is taken into account in more general illumination models. Surfaces where the diffuse term is dominant have a matte appearance.
