摘要:
为在流体模拟的细节表现和流体渲染的实时性方面达到平衡,将浅水方程和光滑粒子流体动力学(SPH)方法相结合,提出了一种基于质量守恒和动量守恒原理的流体交互仿真算法。应用并扩展了SPH方法,实现了虚拟流体与虚拟场景中的静态实体和动态实体的交互。验证实验结果显示,当粒子数控制在104以内时,帧速率达到14帧/s,表明该算法既兼顾了水体的表现细节,又满足了渲染速度的实时性要求。
Abstract:
To balance the detailed behaviors of fluid simulation and the real-time of fluid rendering,the shallow water equation(SWE)and the smoothed particle hydrodynamics(SPH)method are combined,a fluid interaction simulation method based on the mass conservation and momentum conservation principle is proposed.The SPH method is applied and extended,the interactions among still entities and dynamical entities in virtual fluid and virtual scenes are realized.Validation experiment results show the frame rate reaches 14 frames /s when the number of particles is less than 104,the proposed method not only emphasizes the detailed behaviors of virtual water,but also satisfies the real-time requirements of rendering speed.
