Realization of flood simulation visualization based on OpenGL

With the promotion and quick development of the concept of smart city, based on this concept how to predict and eliminate the nature disaster has been more and more possible. This paper gives a outline of how to use OpenGL to realize a system of flood simulation. First using OSGDEM to make a real terrain scene with texture and coordination. Second, based on OpenGL graphic library to simulate the water and the movement. Third, using MFC to realize the visualization of the flood.
