查询词典 topology structure

Finally, the integration of RP technology and RE is deep investigated. Some problems related with surface model and RP technology is pointed out. The method and data structure of reconsfructing the topology information of STL file are proposed. Also addressed in the paper are issues of the mistake check methods and repairing techniques of STL file. Then an experimental procedure of creating interface file and making the seat prototype of a bike is summarized in detail. The result testifies the feasibility and practicability of the technical line presented in this paper. All of the above-mentioned measures, impact the development for realizing the integration of RE/RPM.

最后，对反求技术和快速原型技术的集成问题进行了深入研究；指出了表面模型用于RP＆M中存在的问题；给出了STL文件拓扑重建的方法和数据结构；讨论了STL文件的错误校验和修复技术；在此基础上，进行了快速成型机的接口文件生成和实体成型加工实验，验证了本文所提技术路线的正确性和科学性，为实现RE/RPM的一体化起到了积极地推动作用。

The Geographic Information System theory as a guide, point-set topology theory as basis, this paper uses object-oriented method to study on profile-based three-dimensional topological data model and data structure. By use of computational geometry, GIS, computer graphics images, 3DGM, the construction and dynamic updating methods of 3DGM are researched on the basis of amended OO-Solid data model.
