摘要
随着煤炭的大量开采,塌陷区逐渐增多,严重地破坏了矿区生态结构,影响了矿区及周边地区人们的生活。因此良好的塌陷区漫游系统成为了治理这些危害的关键。三维地形是可视化系统及虚拟仿真的基本组成部分,也是此次项目至关重要的一部分。针对当前三维地形及其渲染技术的研究现状,该文结合常用图形接口OPENGL,在VC＋＋6.0平台下,运用GIS技术和采煤塌陷区地形数据,对LOD技术和ROAM算法进行研究,更好地实现塌陷区漫游效果。
With mining a large number of coal ,the subsidence area gradually increased, it seriously destroyed the ecological struc- ture of mining area, it affects people＇ s life in mining area and the surrounding areas. So a good subsidence area roaming system becomes the key to control these damages. The 3D terrain is a fundamental part of visualization and virtual simulation, it is also crucial part of this project, it aimed at the current research situation of 3D terrain and rendering techniques, In this paper, we combine with commonly used graphics interface OPENGL, on the platform of VC＋＋6.0,use the GIS technology and the terrain data of coal mining subsidence, we research LOD and ROAM algorithm, then realize the effect of the subsidence area＇ s roaming better.
