摘　　要：提出一种基于SPH的运动物体与水交互的仿真建模方法。该方法以坠落物体为例,对物体和水进行粒子化,建立物体粒子与水粒子的受力分析模型和状态更新方法,以及粒子与障碍物的碰撞检测方法,并基于MarchingCubes算法从水粒子的数据中抽取出水的自由运动表面,完成水面绘制。实验结果表明,该方法能获得比较真实的仿真效果,且当粒子数量低于6000个时,可达到实时仿真的速率。A real-time simulating method based on SPH for interaction between motorial solid and water was proposed.This method took falling solid as an example,and particlelized it as well as water.The force analysis and state update models were established for solid and water particles,and a collision detecting method between particles and obstacles was proposed also.The water surface was extracted from water particles based on Marching Cubes for final rendering.Experimental results show that the method is realistic,and can achieve real-time frame rate when particle amount is less than 6000.
