Constructing muti-level TIN with voronoi diagrams
利用Voronoi图构建多级TIN

To study the LOD techniques for large scale terrain visualization, this paper focused on the design of muhiresolution TIN. First, a new approach of constructing multiresolution TIN that represents terrain well was given based on Voronoi diagrams and Delaunay triangulation networks. Second, multiresolution TIN was incorporated, thus making the management and load of it even more easily. The results show that the response speed and display effect are very satisfying. It can make real time and seamless walkthrough in large scale 3D visualization.
