基于强约束Delaunay-TIN的三维地学模拟与可视化
3D-Geosciences Modeling and Visualization Based on Strongly Constrained Delaunay TIN
【摘要】 该文以煤层为例,在分析地层底板空间信息特征的基础上,以地层底板等高线为数据源,基于强约束Delaunay三角形研究含断层约束的三维地学模拟的数据组织方法,设计地层底板要素的数据结构,并讨论底板各要素的拓扑关系。进而以Delphi和OPGL编程,在GeoMo3D系统中开发插件,实现了地层底板的3D可视化和基于Voronoi图的地层体积与矿层储量计算。
【Abstract】 The features of the spatial information of stratum floor is analyzed, and the contours of strata are taken as data sources for 3D geosciences modeling. The data organization for the 3D modeling of stratum with faults are studied based on strongly constrained delaunay triangles. The data structures of the contour’s primitives are designed and the topological relations between the primitives are also discussed. With Delphi and OPGL, a plug-in software for the 3D geosciences modeling system, GeoMo3D, is developed. The 3D visualization for a serial of coal beds and the volume as well as the storage calculation are realized.
