LODManager: a framework for rendering multiresolution models in real-time applications

Abstract

Many papers have addressed the problem of achieving real time visualization in interactive applications where millions of polygons are rendered and many objects are visualized. Multiresolution modeling has proven to be a good solution, as it diminishes the quantity of geometry to render. But this solution is not widely used because it presents inefficient level of detail update routines that lower the overall performance. We are introducing a set of techniques to adapt the level of detail while meeting time constraints and maintaining image quality. In order to fulfil the requirements of current game engines, the LODManager considers exploiting graphics hardware and reuses as possible those levels of detail already calculated. Finally, we will show the integration of our LODManager in a game engine and we will prove the validity of our solution in an interactive application.
