  abstract =   "Ambient occlusion is a shading method which takes light
               occluded by geometry into account. Since this technique
               needs to integrate over a hemisphere it was first only used
               in offline rendering tools. However, the increasing
               resources of modern graphics hardware, enable us to render
               ambient occlusion in realtime. The goal of this report is to
               describe the most popular techniques with respect to
               realtime rendering. First we introduce how ambient occlusion
               is defined and then we will explain and categorize the
               presented techniques. ",
