二维地图与三维虚拟场景交互技术的研究与应用

Research and Application of Interactive Technology Based on Two-dimensional Map and Three-dimensional Scene

在研究了国内外地理信息系统软件的应用与发展、地图可视化的基础上,利用二维地图和三维虚拟场景交互的思想来解决二维地图和三维虚拟场景各自存在的不足,并采用可视化开发工具VisualC++6.0、实时三维视景仿真工具Vega和GIS控件MapObject进行集成,开发了二维地图和三维虚拟场景交互的林火蔓延仿真系统。系统运行稳定,效果良好。

The deficiencies of two-dimensional map and three-dimensional virtual scene were solved by interactively using both of them based on the application and development of GIS software at home and abroad as well as the cartographic visualization. A forest-fire spread simulation system was developed by integrating two-dimensional map with three-dimensional virtu- al scene with the help of visual development tools （Visual C＋＋ 6.0）, real-time 3D visual simulation tools （Vega） and MapObject. Result proved that the system was stable and effective.
