Null interface law

Description

Specular material with a smoke medium (n=1.0) and a null law

The Null interface law has always 100% transmission and 0% reflection. It can be used for simulating a perfect anti-reflection filter, or interfaces between various absorbing media having the same refractive index. It could be also a good model for human tissues in the X-Ray wavelength range. The associated surface is fully invisible, but the object can be seen if its enclosed medium is absorbing.

A Fresnel interface law will give the same results if the media on each side have exactly the same value for n. However, the performance will be lower.
