Research on real time detailed terrain rendering

Three-dimensional terrain generation is one of important factors of the natural scenes in virtual environment. It is also a significant composition of view system in virtual reality field. This paper introduces the necessary of terrain simplification in virtual browse, and concludes the existing algorithm. Then reduces the realtime algorithm of dynamic level of detail terrain rendering and describes its realizing process in detail. At last, this paper also presents the method of removing cracks on the meshes boundary.
