Glossy BSDF



Example of glossy BSDF

BSDF This BSDF type is a generalization of the Phong BSDF for any roughness distribution.

It corresponds to densely diffuse materials, with a surface smooth enough to allow specular reflection, such as smooth paints, laquered or varnished surfaces.

This is a more refined model than Phong BSDF for describing glossy surfaces, as any roughness distribution can be set for modelling the specular reflection component.
