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.Additional Files and Images
