We introduce a multiresolution scheme whose data structure allows us to separately re- store the geometry and topology of a mesh during the refinement process. Additionally, we use a topological criterion (not a geometric criterion, as usual in the literature) to quickly simplify a mesh, what seems to make the corresponding simplification algorithm adequate for real-time appli- cations such as, for example, on-line computer games.engMultiresolutionMeshesjournal article
