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 3D electromagnetic method is improved in such fields as data management, model visualization and interpretation integration.
