dc.description.abstract | Multiresolution representations are becoming more and more important for the visualization, operation and interrogation of very complex scenes. In this paper, an automatic simplification algorithm for general two-manifold polyhedra is presented. The algorithm is based on the generation of an intermediate octree representation of the object and produces a set of valid two-manifold polyhedral approximations of the initial solid ensuring precise distance approximations between the surface of the initial object and the surface of the resulting solids. A restricted non-iterative version of the general algorithm is proposed and implemented for the particular case of isothetic polyhedra. In this case the proposed scheme is specially simple and generates a whole family of isothetic simplifications. |
