摘要：

The multi-resolution adaptive grids method is proposed to solve the problems of inefficiency in the previous grid-based methods, and it can be used in clouds simulation as well as the interactive simulation between objects and clouds. Oriented bounding box (OBB) hierarchical trees of objects are established, and the resolutions of global and local grids can be selected automatically. The motion equations of fluid dynamics are simplified. Upwind difference is applied to ensure the stability of the simulation process during the discrete process of partial differential equations. To solve the speed problem of existed phase functions, the improved phase function is applied to the illumination calculation of clouds. Experimental results show that the proposed methods can promote the simulation efficiency and meet the need for the simulation of large-scale clouds scene. Real-time rendering of clouds and the interaction between clouds and objects have been realized without preprocessing stage. ©, 2015, Nanjing University of Aeronautics an Astronautics.
