The special feature of our approach is that it allows an interactive navigation in very large scenes (30 GB/400 million polygons in our benchmark scenes) that cannot be stored in main memory, but only on a local or remote hard disk. Furthermore, it allows interactive rendering of substantially more complex scenes by instantiating objects. For the computation of an approximate image of the scene, a sampling technique is used. In the preprocessing, a so-called sample tree is built whose nodes contain randomly selected polygons from the scene. This tree only uses space that is linear in the number of polygons. In order to produce an image of the scene, the tree is traversed and polygons stored in the visited nodes are rendered. During the interactive walkthrough, parts of the sample tree are loaded from local or remote hard disk. We implemented our algorithm in a prototypical walkthrough system. Analysis and experiments show that the quality of our images is comparable to images computed by the conventional z-buffer algorithm regardless of the scene topology.}}, author = {{Klein, Jan and Krokowski, Jens and Fischer, Matthias and Wand, Michael and Wanka, Rolf and Meyer auf der Heide, Friedhelm}}, booktitle = {{Proceedings of the ACM symposium on Virtual reality software and technology - VRST '02}}, isbn = {{1581135300}}, title = {{{The randomized sample tree: a data structure for interactive walkthroughs in externally stored virtual environments}}}, doi = {{10.1145/585740.585764}}, year = {{2002}}, } @inproceedings{16491, author = {{Meyer auf der Heide, Friedhelm and Schindelhauer, Christian and Volbert, Klaus and Grünewald, Matthias}}, booktitle = {{Proceedings of the fourteenth annual ACM symposium on Parallel algorithms and architectures - SPAA '02}}, isbn = {{1581135297}}, title = {{{Energy, congestion and dilation in radio networks}}}, doi = {{10.1145/564870.564910}}, year = {{2002}}, } @inbook{16538, author = {{Dellnitz, Michael and Junge, Oliver}}, booktitle = {{Handbook of Dynamical Systems}}, isbn = {{9780444501684}}, issn = {{1874-575X}}, title = {{{Set Oriented Numerical Methods for Dynamical Systems}}}, doi = {{10.1016/s1874-575x(02)80026-1}}, year = {{2002}}, } @article{16556, author = {{Dellnitz, M.}}, issn = {{0272-4979}}, journal = {{IMA Journal of Numerical Analysis}}, pages = {{167--185}}, title = {{{Finding zeros by multilevel subdivision techniques}}}, doi = {{10.1093/imanum/22.2.167}}, year = {{2002}}, } @article{16586, author = {{Elsässer, Robert and Monien, Burkhard and Preis, Robert}}, issn = {{1432-4350}}, journal = {{Theory of Computing Systems}}, pages = {{305--320}}, title = {{{Diffusion Schemes for Load Balancing on Heterogeneous Networks}}}, doi = {{10.1007/s00224-002-1056-4}}, year = {{2002}}, } @article{1667, author = {{Krimphove, Dieter}}, journal = {{Neue Zeitschrift für Arbeitsrecht (NZA)}}, number = {{Heft 13}}, pages = {{724 ff.}}, publisher = {{Verlag C.H.
