Zusammenfassung
Hierarchical approaches are the best means to compute global illumination solutions with finite elements for scenes of high complexity. Most of these methods are based on Hierarchical Radiosity and on its idea of a local refiner, which decides about the level of interaction looking at a single pair of sender and receiver at a moment. Such local refiners are easy to implement, but the neglect of global properties of the entire solution often focuses the computation on details, which are not visible anymore in the final solution. In this paper we propose an extension for \mbox{Hierarchical} Radiosity which introduces the concept of global refinement. This method can be used to better focus the computations on only those details, which are of interest for the global solution.
