摘要：This paper establishes tree model based on L system, and builds the wind field mathematical model added noise disturbance; focusing on the leaves dancing in the branches with the wind and leaves fall in motion; and it avoids the occurrence of the penetration phenomena in the leaf movement process because of using bounding sphere method in combination with the convex polyhedron detection method for collision detection. The whole system is developed by VC++ 6.0 environment combined with OpenGL tool, the simulation process is real and natural, which can meet the requirements of real-time. The proposed algorithm is applied to the leaves motion simulation when wind speed is not too large, the wind model should be improved for the more detailed research in the future, considering the condition of the branch breaking caused by wind speed and the complexity of the tree model structure.
