Web1. If I have an optical transparent slab with refractive index n depending on the distance x from the surface of the slab, the refractive index can be described by: n ( x) = f ( x) where f ( x) is a generic function of x. so, we can write: d n ( x) d x = f ′ ( x) The snell law of refraction states: n 1 sin ( θ 1) = n 2 sin ( θ 2) WebAdding Reflection and Refraction Reading time: 7 mins. The other advantage of ray tracing is that, by extending the idea of ray propagation, we can very easily simulate effects like reflection and refraction, which are handy in simulating glass materials or mirror surfaces.In a 1979 paper entitled "An Improved Illumination Model for Shaded Display", Turner …
