【摘要】 三维地形模型数据库是地形可视化仿真应用的重要数据基础。虚拟地形环境构建技术改变了矿山资源勘查传统方式, 实现了虚拟找矿与勘探。从Creator三维仿真建模系统的技术特点出发探讨了创建矿山资源勘查的虚拟三维地形模型数据库的技术方法和流程,结合实际经验指出了在原始地形数据处理、地形转换算法选择,地形纹理应用以及地形批处理生成等过程中常用方法和技巧。重点讨论了Creator提供的Polymesh、Delaunay、CAT和TCT四种地形转换算法选择。最后给出了阜新某矿区一个矿山区域的地形仿真模型建立的实际例子。更多还原

【Abstract】 The 3D modeling database is an important foundation data in the application of terrain visualization. Virtual geological environment of mine has changed the traditional methods of prospecting for mine. This paper discussed the techniques and flow from the point of view of the characteristics based on Creator simulation platform system. It is based upon practice experiences that pointing out the common methods and techniques cover with dealing with the original terrain data, appropriate choice of terrain conversion arithmetic, application of terrain texture and terrain file batch generation. The emphases is discussing Polymesh, Delaunay, CAT and TCT terrain conversion arithmetic which are provided by Creator. In the end, giving a practical terrain simulation modeling example of a mine region in Fuxin diggings.更多还原
