摘　　要：地质钻孔资料是记录地质结构原始信息的载体,其三维可视化是精细化地质研究的基本表现形式和重要技术手段。在分析、对比国内外钻孔三维可视化不同方法的基础上,采用Multipatch模型进行钻孔的三维建模与表达。探讨了钻孔三维可视化的技术流程,三维钻孔表达的几何构建、纹理渲染与自动匹配等关键技术。最后基于Arc GIS Engine开发了测试系统,并与当前常用的地质钻孔软件进行了比较,验证了方法的有效性。The Borehole is so important in geological-related industries for which records the original informations of the geological structure. Their 3D visualization is fundamental to the geological researching. In this paper, we employed a new method named Multipatch which was so efficient to modeling 3D surface features through analyzing contrastively different techniques in boreholes 3D visualization. Then, we gave the technical progress of 3D visualization, explained how to build geometric model and how to render by texture and so on. At last, we developed a prototype system using ArcGIS Engine to verify the effectiveness of the way. The experiment proved the way was advisable using Multipatch to construct the 3D model of boreholes.
