Executive Summary

There are many relations between 3D spatial objects, such as metric relations, order relations and topological relations. The most important relation is topological relation, which represents the inherent features of spatial objects that do not change with the observing angle or zooming transformation. The typical topological relations include inside and disjoint. Topological relations have important application value in spatial information query and can improve the accuracy of the input of spatial information. Nowadays the researches mostly focus on the topological analysis between connected region objects in 2D plane. However, the researches on 3D spatial objects especially the body objects with holes are really insufficient.
