We present an integral equation which generalizes a variety of known rendering algorithms. In the course of discussing a Monte Carlo solution we also present a new form of variance reduction, called Hierarchical sampling and give a number of elaborations shows that it may be an efficient new technique for a wide variety of Monte Carlo procedures. The resulting rendering algorithm extends the range of optical phenomena which can be effectively simulated.
