Abstract: Todays graphics hardware is capable of performing a large number of operations at very high rates. Since most of the graphics chips are designed in a pipelined fashion, e.g. similar to the OpenGL rendering pipeline, it is necessary to utilize as many processing units as possible to achieve high-quality results while keeping the number of rendering passes needed at a minimum. In this paper we present an algorithm that combines two well known algorithms in a very efficient manner. One is the \textit{shadow mapping} technique that is used to compute a shadow mask to determine lit and shadowed pixels. The second algorithm is called \textit{light mapping} and is a common approach for rendering complex light effects. These two are combined into a single texture map which we call an \textit{extended light map}. The benefit of this approach is that nearly all stages of the graphics pipeline can be used during the shadow map generation phase, which results in better image quality and a reduced number of rendering passes.
