               Large scale urban visualization or outdoor game environments
               set highest demands on the visual complexity of the virtual
               world. The frame rate on the other hand has to stay above 60
               frames per seconds, otherwise movements and animations are
               not perceived smoothly anymore. Even though hardware gets
               faster every year, geometry simplification is essential to
               distribute the resources for optimal quality and
               performance.  This thesis gives an overview of geometry
               simplification algorithms based on the billboard cloud
               principle. The problematic of the summarized algorithms are
               discussed and several improvements and possible
               modifications are described. The focus is on reducing
               simplification artifacts and improving the performance
               without affecting the visual quality. Finally, the results
               will be presented in an extensive evaluation. From the
               gained insight rules and parameters for an automatic
               geometry simplification process will be derived.",
