# Simple interface law¶

## Description¶

Specular material with a glass bulk medium and a simple interface law, with r0=0.04

The Simple interface law computes reflection and transmission coefficients from a simple non-physical equation approximating Fresnel coefficients, the Schlick’s approximation. It takes as only parameter r0, the reflection coefficient at normal incidence. The reflection coefficient varies from r0 to 1 from normal to grazing incidence.

Note

This interface law was renamed from “default” to “simple” after Ocean 2015 beta3
