A View dependent Dynamic Multi Resolution Terrain Model of TIN

A "hui" structure LOD(level of detail) model TIN based is presented in this paper. The algorithm achieves the experiment effect: the nearer the terrain is away from the viewpoint, the clearer it is. It avoids the triangles crossing or overlapping, and creating some thin triangles. The experiment shows that with this algorithm, the dynamic continuous terrain multi-resolution model will come true.
