摘　　要：为了获取三维地质体任意方向的剖面图,在四面体建模的基础上,利用面与面之间的相切关系以及四面体剖切后拓扑关系的一致性,在三角形自分解基础上完成了三维地质体的任意剖切,并在VC环境下利用OpenGL对该剖切进行了显示。仿真结果表明,该方法实现了三维地质体任意方向的剖切处理,提高了绘制地质剖面图的效率。In order to obtain section of 3D geology model in arbitrary direction,arbitrary sectioning of 3D geology model was finished by use of tangent relation between surfaces and consistency of topological relation after sectioning of tetrahedron based on modeling of tetrahedron and self-decomposition of triangular.The sectioning was showed by OpenGL under VC.The simulation result showed that the method realizes arbitrary sectioning processing of 3D geology model and improves efficiency of draw geological section.
