摘　　要：提出基于限制四叉树的不同分辨率网络模型之间的网格递进方法,实现了在模型误差控制下视点相关的多分辨网格的实时正确构网。实验证明,该方法对于实时控制大规模地形模型的细节层次,增强大规模地形模型的绘制效率是非常有效的。Proposes a method of progressive meshes based on restricted quadtree between blocks of different resolution, and the real-time dynamic triangulation controlled by giving view dependent error come true. The experiments show that this algorithm is very. good of the real-time LoD controlling for large scale terrain visualization and also for the real-time rendering.
