| Abstract: | This article briefly introduces a construction model of large-scale terrain based on quadtree, then a LOD model based on binary triangle trees is presented. Combining with Terrain Blocks Strategy and an algorithm called real_time optimally adapting meshes, the article discusses a model of real_time triangulation controlled by view point error. And a realization method of this LOD model is showed. |
