Formal topological description of three-dimensional topological entities based on k-dimensional pseudo-manifold
Xiaoli Zhao
Abstract:This paper clarifies the necessity of studying three-dimensional spatial data models, analyzes the research progress and existing problems of topological spatial relationship description methods, and proposes a complete and formal description framework of three-dimensional topological spatial relations based on point set topological theory and dimension expansion method. On this basis, the topological spatial relations existing in three-dimensional spatial objects are classified, and five fundamental topologic… Show more
