| 摘 要： | 地形三维可视化一直以来是地理信息系统、数字摄影测量、虚拟现实等领域的研究热点。本文基于地形三维可视化的重要性和徐州龟山汉墓虚拟重建研究的需要,提出了应用ArcView辅助Creator生成三维地形的方法,以ArcView中生成的Raster专题层作为Creator生成三维地形的高程数据源,通过地形细节层次的创建、高程模型的投影变换、地形转换算法的选择和地形纹理的映射,生成了大面积精确地形,在龟山汉墓虚拟重建系统中取得了良好的实时显示效果。

| Abstract: | Three-dimension terrain visualization has become the key research field in the GIS,Ditital Photogrammetry and Virtual Realization.Based on the essentiality of the three-dimension terrain visualization and requirement of the Guishan tomb vitual reconstruction in xuzhou,a method for creating three-dimension terrain in Creator with the help of ArcView is introduced.the raster data from ArcView as the original elevation data,through setting of terrain LOD,projection transformation of the elevation model,selection of the terrain transition arithmetic and mapping of the terrain texture,a large accurate terrain is generated in Creator.In the 3D virtual reality system of Guishan tomb, a real time effect can be acquired. |
