Abstract:
We describe the integration of heterogeneous participating media into our production ray tracer. We specifically focus on the problem of computing the lighting without incurring a quadratic number of shader evaluations. The main difficulty in rendering volumes comes from the inability to analytically importance sample the transmission term: [EQUATION]
