摘要: 为了强化地质体三维模型的空间分析与表达能力,文中基于单纯剖分理论给出了地质体三维建模方法,探讨了基于包容单形的三维地质体特征点、线、面的表达,给出了边界面查询、地质面搜索、地质线追踪等算法。试验结果表明,这种单纯剖分建模方法实现简单,表达丰富,可以完成其它建模方法无法完成的拓扑分析、边界查询等许多功能。作为三维地质模型的基础、关键问题之一,此新的建模思路将促进三维地质模型的深入研究与应用。

Abstract: To strengthen the spatial analysis and representation capacity of 3D geological bodies model, the paper presents a modeling method based on the simple partitioning theory, discusses the representation of 3D characteristic geological point, line, and polygon based on simple container, and put forwards such algorithms as boundary query, geological area search, geological line tracing, etc. Characterized by simple realization and abundant representation, this model can complete the topological analysis and boundary search that other models cannot do.  As one of the basic and key issues, this new modeling idea will speed the research and application of 3D geological model.
