- Mar 27, 2024 Layered Materials and the Fresnel Coupling Between Coats and Substrates How a clear coat sits on a base material, why the transmitted share at each interface is not simply one minus the reflected share, and how internal reflection traps light inside a layer. computer graphics
- Mar 2, 2023 Fresnel Reflectance for Dielectrics and Conductors Why reflectance rises to one at grazing angles, how the index of refraction and extinction coefficient determine the normal-incidence value, and how Schlick approximation departs from the exact curves. computer graphics
