Lambertian shading function

WebbSpecular reflections were among the first deviations from the Lambertian model. These are a few adaptations that have been developed. Many techniques ultimately rely on modelling the reflectance function of the surface, that is, how much light is reflected in each direction. [6] This reflectance function has to be invertible.

It depends on the angle of incidence of the incident flux and the wavelength of this radiation. It also depends on the direction in which the scattered light is measured as well as the wavelength and polarization of the incident and scattered flux.
