摘要
论述了OpenGL技术的特点以及主要工作原理,并针对矿山地质剖面图的绘制,提出了在原始勘探地质数据处理的基础上,应用OpenGL技术建立矿体的三维表面线框模型的理论和方法;通过建立矿体三维实体模型,可以从不同角度全方位地观测矿体的空间态势,从总体上控制矿体的空间形态,实现地质剖面图的任意自动剖切。在此基础上设计并开发了基于OpenGL技术的相应软件。该软件可以用来建立矿体三维模型,实现地质剖面图的任意剖切,大大地提高了地质剖面图的准确性和工作人员效率。
This paper discusses the technical characteristic and primary principles of OpenGL technology. After the crude geological data are processed, This paper puts forward the principles and methods of creating three-dimensional solid model to draw the geological section map using the OpenGL technology. Three-dimensional solid model being established, it is practicable for us to observe the ore body from various angles, control the outline of the ore body as a whole and create geological section map automatically in any orientation. Finally, a suit of software is designed and developed to be used to establish three-dimensional solid model of ore body and create geological section map automatically in any orientation, It has greatly improved the accuracy of geological section map and the efficiency of the geological technicians.
