【摘要】 通过对钻孔线状数据进行有效的分层,直接根据各个层面的标高,应用不规则三角网(TIN)表面法和克里格(kriging)内插算法构建三维体数据,从而实现地质三维重构。并基于IDL开发环境,采用光线投射法和z_buffer相结合的直接体绘制算法,实现地质三维分析和可视化。同时研发了福州市地热田热储结构系统,实现了地质真三维交互式切割分析、显示和查询。更多还原

【Abstract】 The borehole data are linear interpolated on geological characters, then are divided into sections on levels. Based on the triangulation (Delaunay) and Kriging interpolation, the geological layer and triangular grid are constructed. According to grid data structure, 3D data are generated. Direct Volume Rendering is employed,which includes ray_casting and z_buffer arithmetic. Visualization is realized with programmable data analysis and visualization environment IDL. At the same time , we have developed Fuzhou geothermal field three-dimension visualization system。It has realized three-dimensional interactive incision, analysis and query successfully.更多还原
