【摘要】 本文紧紧围绕露天矿矿床三维模型的建立与可视化这一主题，将矿床模型分为地质表面模型和矿床实体模型，地质表面模型由地质界面和地表面组成，用边界和断层的上下盘多边形对地质界面的插值曲面进行裁剪，生成地质界面的裁剪曲面，以地质界面的裁剪曲面和地表面的三角形剖分面按空间组合矿床实体模型。以伊敏露天矿为实例，用VC++6． 0和OpenGL开发了矿床模型三维可视化系统，实现了矿床模型的三维可视化与任意角度显示，以及矿床模型图形数据库的建立、模型的修改与实时动态更新、绘制任意剖面等功能。更多还原

【Abstract】 The article centers on the development of open pit mine’s 3D visualization deposit model. The deposit model includes geological surface model and body model. The geological surface model is composed by the geological interface and the earth’s surface. The interpolation face of geological interface is trimmed by boundary and the closed polygons of up and down faulted blocks to form the trimmed surface. The body deposit model is composed by the trimmed surface of geological interface and the triangulation earth’s surface according to spatial relationship of these elements. Yimin open pit mine is taken for example, the 3D deposit model visualization system has been developed on VC++6.0 and OpenGL. The system can display the 3D deposit model in any direction, found graphics data of deposit model, modify and update the deposit model and draw any direction section.更多还原
