摘　　要：笔者选择OGRE 3D作为数字煤矿三维可视化渲染引擎,提出了基于OGRE 3D的煤层三维建模流程方法和煤层精细纹理的制作方法。其中,煤层模型构建的流程是:对于煤层,首先根据煤层底板等值线、断层、陷落柱和边界数据,采用基于线状信息源的分区综合插值法得到煤层底板的GRID文件,再加上煤厚数据,分块生成包含煤层体6个面的XML文件(每个XML文件存储的都是不规则三角网数据),然后生成可供OGRE 3D使用的包含层次细节信息的Mesh模型,最终通过OGRE 3D渲染生成模拟煤层。This paper presented a 3D eoalmine visualization system based on Ogre 3D engine, in which the eoalbeds were modeled through a novel approaeh for rendering and retrieving. For modeling eoalbeds, eoal floors were first seg- mented into bloeks with eollapse eolumns, faults and boundaries, within whieh the interpolation based on floor eon- tours was further performed to obtain the floor elevation grid, and then the Triangulated Irregular Network （TIN） being filled with irregular hexahedrons were generated based on the floor elevation grid and the eoalbed thiekness informarion, and finally the level-of-detail mesh database was prepared for Ogre rendering based on the above TIN. Finally, virtual eoalbeds were generated through Ogre 3D rendering.
