摘　　要：对三维地形可视化地形图开发中的几个关健技术进行了分析和研究。利用VC++和OpenGL作为开发工具,通过建立位图的灰度值与地形高程之间的映射关系,快速生成三维地形,然后再经过纹理贴图与种植随机树,产生具有较强真实感的三维可视化地形图。Analysis and research several key technologies in development of 3d visualization terrain map. Adopt VC＋＋ and OpenGL as the development tool, establish the mapping relation between gray-number of bitmap and terrain altitude, generation three-dimensional terrain quickly. Then, through texture-pasting and planting random trees, creates three-dimensional visualization terrain map with strong truthfulness.

关 键 词：OPENGL 可视化 纹理贴图 随机树
