| 摘 要： | 以OpenGL为工具,在VisualC++程序设计语言为平台上建立一个三维虚拟林相模型。通过坐标系设定、DEM加载、地形纹理设置、树木模型建立、天空建立等过程,说明虚拟林相建立的理论、方法和过程。最终实现了三维虚拟林相的显示、放大缩小和漫游功能。实践证明,所述的原理和方法能所实现的显示效果与ERDAS虚拟现实模块的效果基本相同,可以为林业规划显示系统的开发提供模块和技术支持。

| Abstract: | The aim of this research is to establish a 3D virtual forest visualization system based on OpenGL language on Visual C++ design platform.The functions of display,zooming,and roaming were realized by means of coordinate setting,DEM loading,terrain texture setting,tree model establishment and sky building.Practice proved that the method used in this paper could achieve a desired effect similar to that of the module of ERDAS and could provide technical support and module support for the exploitation of display... |
