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.

Web7 mei 2024 · In optics, the refractive index (or refraction index) of an optical medium is a dimensionless number that gives the indication of the light bending ability of that medium. The refractive index determines how much the path of light is bent, or refracted, when entering a material. This is described by Snell's law of refraction, n1 sin θ1 = n2 ...
