| 摘 要： | 针对目前三维GIS领域缺少城市海量三维场景的快速裁剪算法,方便城市三维数据的分发与应用,本文在对三维场景进行分区组织以及动态调度的基础上,提出了一种层-区-块-模型四层次由粗到精的快速真三维裁剪算法。数个城市的应用实践证明,该算法准确、高效,适用于城市海量三维场景的快速裁剪。

| Abstract: | As there is little study in the clip algorithm of massive urban 3D scene in 3D GIS fields to realize convenient distribution and application of 3D urban data,a fast clip algorithm is proposed in this paper.Being applied in several cities,it has been proved that this algorithm is accurate,efficient and can be applicable to the clipping in massive urban 3D scene. |
