With the increasing demand for the application of future simulation technology and virtual reality, the virtual environment modeling techniques will become increasingly important. Three dimensional terrain is one of important factors of the natural scenes in virtual environment and it is also a significant composition of view system in virtual simulation field. Firstly, this paper describes the research content and research objectives of the large-scale terrain modeling. Secondly, it systematically analyses research methods and techniques of terrain modeling simplification algorithms in recent years, including static and dynamic simplification algorithm, and compares the advantages and disadvantages of each method. Finally, future research directions are discussed.
