Web27 okt. 2024 · MeshPhysicalMaterial includes some properties that estimate refraction through the transmissible object: thickness, ior (Index-of-refraction) and reflectivity. We’ll mostly ignore ior and reflectivity (which changes ior too, but is mapped to a 0-1 range) as the defaults work great! thickness is the magic here, as we’ll see shortly. Clearcoat Web1 nov. 2024 · For real materials, the IOR is a function of the wavelength λ of light. This property is called dispersion. For example, the IOR of N-BK7 glass, a common glass for laboratory optics, varies between n = 1.53 at a λ = 400 nm, to n = 1.51 at λ = 800 nm. This may not seem a big difference, but it has significant impact on imaging optics.
