基于粒子系统的流体交互应用

Fluid simulation for interactive applications based on particle system

为模拟水流的真实交互行为,采用基于光滑粒子流体动力学方法的粒子系统进行水流的物理仿真。给出利用八叉树建立有序树并进行最近相邻粒子搜索的方法,采用两种虚粒子结合的方法处理边界条件。在三维虚拟场景中模拟了水流与障碍物交互的过程,证明了该方法的实时性和可行性。

In order to simulate the real interactive behavior of flow, this paper presented a method for physical fluid simulation using particle system based on the smooth particle hydrodynamics method. This method introduced a nearest neighbor particle searching method with the octree and adopted double virtual particle to build the boundary condition. At last,implemented an interaction between fluid and obstruction in real-time three-dimensional virtual scene. This method is completely effective and feasibly for fluid simulation.
