The improvement in performance of computers has become possible to display complex 3D graphics. However, when using a uniform mesh, number of polygons increases. In addition, it takes more time to generate and to display the polygon. We propose a real-time landscape simulation system through the fuzzy theory. In this system, we reduce the polygon by using a partition tree. Furthermore, we propose a method of changing the view point moves in real-time based on the altitude.
