Thin Glass Material (thnGlss)
- color: normal reflectance (typical real glass is .04)
- color: transmission
Simplistic transparency with attenuated transmission, Fresnel
reflectance, but no refraction (to ease the pain of sampling light
sources). Transmission is constant at all angles.
Two Kronecker delta functions:
- in the incident direction
(i.e. passing right through the surface), attenuated
by the given transmission.
- in the reflection direction, with intensity
scaled by the Fresnel reflectance for a dielectric.
