Lambertian BSDF¶
Description¶

Example of lambertian 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.
