Lambertian BSDF

Example of lambertian BSDF

BSDF This BSDF type follows the Lambertian reflectance model. The apparent brightness of such a surface to an observer is the same regardless of the observer’s angle of view. This simple model describes efficiently diffuse surfaces, but more complex models such as Oren-Nayar or Phong will describe better very rough and slightly reflective BSDFs, respectively.
