Detailed Description

Interaction model for analytic dielectric-dielectric and dielectric-metal surface interactions.

Uses the refractive indices of two materials in Fresnel equations to determine the reflectivity of a photon incident on the physical surface. The reflectivity is sampled to determine whether the photon refracts into the next material or reflects. Reflection follows the UNIFIED model (see ReflectionFormSampler). Refracted waves fall into two cases:

1. dielectric-metal: the photon is immediately absorbed.
2. dielectric-dielectric: refracted direction and polarization are calculate from Fresnel equations.
