Raytracing of dispersion effects in transparent materials

In this paper we present a stochastic add–on extension to standard raytracing which makes it possible to render dispersion effectsmore efficiently than hitherto possible. Our method incurs less overhead than previous proposals, is physically accurate and is applicable to most of the currently feasible spectral representations.
