MEMORY-EFFICIENT VIEW-DEPENDENT LEVEL OF DETAIL OF HIGH-DETAILED MESHES

Abstract

In this paper we propose an effective and efficient out-of-core LOD framework for arbitrary irregular high-detailed triangular meshes and scenes. We modify and extend the standard Multi-Triangulation framework to reduce CPU load and to increase RAM efficiency by paging. To reduce the number of IO-operations we propose a novel partitioning scheme well suitable for view-dependant LOD. In addition a fast but very effective caching strategy is proposed, which bases on a LOD prediction for future frames. The efficiency of our framework is shown by results.
