Returns the refraction vector for the given Ray Direction vector, surface defined by the Normal vector and the Refraction Index.
The Refraction Index is the ratio of indices of refraction for two transparent environments. If you want to get a refraction vector for a material with IOR 1.6, pass 1 / 1.6 value to the input.
