| 摘 要： | INTRODUCTIONTornado is one of the most terrible natural phe- nomena in the world. It causes incredible amounts of damage and destroys significant numbers of facilities every year. No wonder it receives great attention as a major research topic in many fields. Realistic simu- lation of tornado is also a great challenge for com- puter graphics researchers. It provides useful infor- mation for natural disaster prevention and can be integrated into entertainment, computer games, etc. Most to…

| Abstract: | Realistic modeling and rendering of dynamic tornado scene is recognized as a challenging task for researchers of computer graphics. In this paper a new physically based method for simulating and animating tornado scene is presented. We first propose a Two-Fluid model based on the physical theory of tornado, then we simulate the flow of tornado and its interaction with surrounding objects such as debris, etc. Taking the scattering and absorption of light by the participating media into account, the illumination effects of the tornado scene can be generated realistically. With the support of graphics hardware, various kinds of dynamic tornado scenes can be rendered at interactive rates. |
