## A study of the fast solution of the occluded radiosity equation

Kendall Atkinson and David Chien

### Abstract

Consider the numerical solution of the radiosity equation over an occluded surface $S$ using a collocation method based on piecewise polynomial interpolation. Hackbusch and Nowak [Numer. Math., 54 (1989) pp. 463–491] proposed a fast method of solution for boundary integral equations, and we consider the application of their method to the collocation solution of the radiosity equation. We give a combined analytical and experimental study of the ‘clustering method’ of Hackbusch and Nowak, yielding further insight into the method.
