Out of Core continuous LoD-Hierarchies for Large Triangle Meshes
Hermann Birkholz · Digital Library (University of West Bohemia) · 2006
In this paper, algorithms for the simplification and reconstruction of large triangle meshes are described. The simplification process creates an edge-collapse hierarchy in external memory, which is used for online reconstruction. The hierarchy indices are renamed after simplification, in order to allow fast reconstructions and the hierarchy is extended with information for view-dependent rendering. The simplification makes no restrictions with the production of the hierarchy, but produces the same hierarchy as In-Core algorithms. The amount of memory, which is used for the simplification is adjustable.
