....has genus six. tex pair collapses during progressive mesh [17] construction, sacrificing the manifold property to better deal with many connected components. A fully general treatment was given by Popovi c and Hoppe [30] Topology reduction as an explicit goal was pursued by El Sana and Varshney [9]. None of these algorithms attempt to maintain the 2 manifold property as we do. Figure 2: A remesh of the bunny head: the left ear uses a standard semi regular mesh, while the right ear uses a hybrid mesh. Starting from a single quad extra skin is provided for the right ear after three regular ....

.... persistence of non bounding cycles is based on the incremental Betti number algorithm of Delfinado and Edelsbrunner [2] Three dimensional alpha shapes and complexes may be found in Edelsbrunner and Mucke [4] The problem of topological simplification was also approached by El Sana and Varshney [5] using alpha shape inspired ideas of geometric growth. There is a large body of parallel work on iso surfaces or level sets of 3 dimensional density functions. We refer to Milnor [8] for the mathematics and to Sethian [11] for a numerical view. A density function is a map F : R R and an ....

....Thus, LOD management is sometimes referred to as contribution culling. Several level of detail approaches have been used in the various walkthrough systems. Some systems use several static levels of detail, usually 3 10, which are constructed off line using various simplification techniques [25,36,44,70,81]. Then at real time, an appropriate level of detail is selected based on various criteria such as distance from the user s viewpoint and screen space projection. Other systems use a multi resolution hierarchy, which encodes all the levels of detail, and is constructed off line [31, 37,50,51,64, ....
