基于物理的海浪模拟综述

Overview of Physically-based Ocean Waves Simulation

真实感流体的模拟是计算机图形学领域中研究的热点和难点之一,海浪模拟是流体模拟动画的重要组成部分,其真实感、实时性和交互性等直接影响到海面场景逼真的程度。重点回顾了基于物理的海浪模拟研究方法的发展,并对近年来海浪模拟的热点问题如波浪的翻卷和破碎、浪花的飞溅和泡沫、流固耦合、两相流和多相流的模拟进行了详细的分析,最后针对有限的系统资源与随着规模增长的计算资源之间的矛盾,重点讨论了加速策略。未来将结合多种模拟方法的优点,对海浪建模进行合理的简化,改善数据结构,并在此基础上实现GPU并行化,以满足实时仿真的要求,这将是基于物理的海浪模拟的发展方向。

Realistic fluid simulation is one of the hotspots and difficulties in computer graphics. Ocean waves simulation is an important part of the fluid simulation in computer animation, and reality, real time and interaction are the key of the simulation of the ocean wave scene. This paper presented a survey of the development of physically based ocean waves simulation, introduced the hotspots of ocean wave simulation such as advection, overturning, breaking waves, splash, foam,fluid-solid interaction, multi-phase fluid in detail and focused on the acceleration technology because the system resources could not meet the demands of modeling computing. Future research is using various methods to opti- mize reasonably the wave modeling and improve the data structure, and implement on GPU using CUDA in order to meet the demand of real time wave simulation.
