摘要
三维拓扑关系是三维空间关系中最重要的空间关系,是三维空间数据表达、查询、分析与应用的理论基础,是目前拓扑关系研究的热点。本文从三维空间实体的定义和描述、三维拓扑关系描述、表达与应用等方面回顾了国内外学术界所取得的研究进展,同时分析了存在的一些基本问题。
3D topological relationship is one of the most important study issues of spatial relationship. It is the theory of fundamental for the representation, query analysis and application of three dimensional spatial data. The research activities and developments in the area of the definition and description of 3D entity, 3D topological relationship description, representation and application are reviewed in this paper. Finally, some basic problems are analysed.
