Abstract
'Shadow profiling' measures shadow durations on an arbitrary scene during several hours of a specific day or even several weeks or months. The result is to be displayed visually. We shortly discuss already known techniques like simplified radiosity or discontinuity meshing with regard to their suitability for this problem. Due to various drawbacks of these techniques, we present our won approach. Especially a pixel-oriented version works very efficiently in connection with fast polygon-oriented shadow algorithms. It can be applied to architectural design, and it can also be used in computer graphics for the computation-inexpensive simulation of complex light sources.
