class DielectricBSDF

Wavelength-dependent, thin dielectric BSDF defined at a single point on a surface in 3-space. The opacity input controls the transmittance versus reflectance of different wavelengths. A pure specular mirror may be obtained by creating a dielectric BSDF with zero opacity. Conversely, a purely transparent surface may be obtained by creating a dielectric with full opacity. Note that a completely transparent surface will still reflect some light (in proportion to Fresnel's Laws) because refraction is undefined past a critical angle when light is traveling between a lighter and denser medium. When this happens, some light is reflected regardless of the opacity parameter, and this is typically known as total internal reflection. More...
