Abstract

In this talk we present an ensemble of common visibility algorithms found in modern video games. We consider both offline and online visibility algorithms and discuss the tradeoffs between different methods from a video game perspective. The widespread availability of hardware occlusion queries has lead to increased interest in online occlusion culling and together with and overview of an hierarchical occlusion query algorithm we will consider some common pitfalls related to hardware occlusion queries in depth.
