摘要
数字高程模型是当今地理信息产业的主要产品之一,是地形环境仿真的基础。在系统介绍三维技术的发展现状、基于OpenGL的地形三维可视化实现的基础上,提出了以数字高程模型为数据基础的三维可视化的方法,探讨了其实现中的关键技术问题,并指出了基于OpenGL的地形三维可视化、地形仿真的前景和发展趋势。
The digital elevated model is one of the main products of the geography information industry ,is the foundation of landform emulation. This paper introduces the present development of three dimension technology,based on the reality of three dimensional visualization of OpenGL, and put forward the digital elevated model based on the three dimensional method, inquired the key technique problem in the process of realization, and pointed out the true foreground and the development trends of three dimensional visualization of OpenGL and landform emulation.
