| Abstract: | It is presented a LOD-based algorithm of TIN model, which is quite suitable for terrain rendering in large 3D landscape. The emphasis focuses on issues of transition between TIN models with different resolutions, and generation of these models, such as how to design data structures and how to optimize algorithms when constructing a Delaunay triangulation. |
