【摘要】 为满足电磁法三维数值模拟解释对交互建模与可视化网格剖分的需求,利用计算机图形学、人机交互、拓扑关系学等技术,设计了起伏地形下三维矢量交互建模、四面体和六面体网格剖分流程,并开发了软件模块。该软件可提供起伏地形下电磁法三维数值模拟的四面体、六面体网格剖分的实用化工具,提高了电磁法三维在数据模拟与解释方面的可视化程度和计算效率。更多还原

【Abstract】 Using some techniques such as computer graphics,human-computer interaction,and topological relation,the authors designed the process about the three-dimensional vector modeling under undulating topography,tetrahedron mesh generation,and hexahedral mesh generation. Through the study,the corresponding software module was developed. In the software,some tetrahedron mesh generation and hexahedral mesh generation utility tools can be provided to solve some related problems in MT. The efficiency of 3 D electromagnetic method is improved in such fields as data management,model visualization and interpretation integration.更多还原
