Subject: Marc Stamminger,Hans-peter Seidel A Comparison of Different Refiners for Hierarchical Radiosity

Description: Hierarchical methods have proven to be a very powerful tool for computations of global illumination solutions in virtual worlds. Since the introduction of the hierarchical radiosity algorithm, many improvements on the method have been made, but the general structure of the algorithm remained unchanged. The complete computation is steered by a refiner method (often called oracle) , which decides on the resolution level of the hierarchical computations. In this paper we show several possibilities for such refiners, discuss their advantages and disadvantages and show first results measuring the computation error for some test scenes. 1 Introduction Global illumination computations, in particular the simplification of radiosity simulations, have been a field of research for many years. One big step forward was the introduction of the hierarchical radiosity method [4]. The aim of that algorithm is to find an approximation for the radiosity transport between two patches p and q. If in a vir...
