Fresnel interface law



Specular material with a glass bulk medium and a Fresnel law

Interface law The Fresnel interface law computes reflection and transmission coefficients from Fresnel equations. For this, it uses the refractive indices of scene media located in front and behind the surface. These media are associated to materials and scene geometry (closed volumes), and not to the interface law itself.

It is especially suited for dielectric materials, such as glass, polymers, water, etc…

For materials with complex refractive index, such as metals or semiconductors, this law is not accurate. Please use Complex Fresnel interface law instead.

The polarization state of light is computed accurately by this law.
