We use a custom, parallel rasterization pipeline for creation and evaluation of the beams. In this paper we present a method which integrates diffraction, on top of the usual effects related to global illumination like reflection, into our beam tracing algorithm. At such frequencies, waves that bend around corners due to diffraction are becoming an important propagation effect. However, their wavelengths are of proportions similar to that of the environment. The simulation of radio waves is conceptually analogous to the problem of light transport. This allows us to apply the algorithm in a novel way to the problem of radio wave propagation. It is an efficient algorithm, and performs very well when implemented on the GPU. Beam tracing can be used for solving global illumination problems.
