| 中文摘要: |
| 不可压缩流体的模拟作为计算机图形学的重要研究领域之一，为增强现实、丰富虚拟环境等提供了重要的技术支持，然而如何实时模拟真实感强、更复杂的流体流动效果一直是计算机图形学的难点。以不可压流体仿真领域常用的方法为主线，对近些年来国内外学者在该研究领域取得的成果进行了系统性分析。首先介绍求解不可压缩流体纳维-斯托克斯方程(N-S)的具体步骤。其次根据现有流体仿真方法的特点，分别对基于物理的Lagrange粒子法、Eular网格法、粒子-网格混合法进行了综述，并对各个方法进行对比分析。最后，总结并展望了该领域在未来研究中的重要研究方向。 |

| As one of the important research fields of computer graphics, simulation of incompressible fluid provides important technical support for augmented reality and rich virtual environment. However, how to simulate realistic and more complex fluid flow effects in real time has always been a difficulty in computer graphics.Based on the methods commonly used in the field of incompressible fluid simulation, the achievements made by domestic and foreign scholars in this field in recent years are systematically analyzed.First, the specific steps of solving Navier-Stokes equation (N-S) for incompressible fluid are introduced.Secondly, according to the characteristics of existing fluid simulation methods, the physics-based Lagrange particle method, Eular grid method and particle-grid hybrid method are respectively reviewed. Finally, the important research directions in this field in the future are summarized and prospected. |
