| Abstract: | Discusse an algorithm of real-time dynamic triangulation based on restricted quadtree for large scale terrain visualization. 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. |
