Titel
A Dynamical Quadtree Hierarchical Radiosity Algorithm in Thermal Radiation Modelling
Abstract
We introduce a new approach for the computation of thermal radiation problems in complex scenes based on a dynamical hierarchial concept. In thermal radiation research this is the first approach including the concept of hierarchical radiosity, while in computer graphics the application of radiosity to no-linear problems, as occur in thermal radiation due to the T4 dependency of the emissive flux, is also a matter of interest. In this paper thermal radiation (TR) and computer graphics (CG) research concerning radiosity are reviewed, with special emphasis on nogrey surfaces and hierarchical methods. The proposed method allows a faster convergence of the energy equation. Benefits are quantified in a test case in relation to the traditional regular mesh discretization algorithm
