基于物理的流体模拟近年来成为计算机动画领域的一个研究热点．回顾了该领域中基于物理的流体模拟的发展情况，总结了该研究方向所采用的各类方法，并结合各种现象的特点分门别类地详细展开其方法总体上可

以分为欧拉法和拉格朗日法，涉及的现象包括烟雾、火焰、爆炸、波浪、气泡以及*界面等．最后展望了未来发

展的3个重点：细节策略、加速策略和控制策略，以使整个模拟能够更好地满足人们对真实感、实时性以及灵活性的

需求．-This paper presents a survey on the development of physically based fluid simulation in

computer animation，with a detail introduction to the classification of the topic as well as the methods

employed in the field．The methods applied mainly include Euler method and Lagrangian method，for

simulating the fluid phenomena such as smoke，fire，explosion，wave，bubble，free surface etc．Future

work is als0 discussed．including detail techniques．acceleration techniques and control techniques used to

meet the demands of reality，real—time production，and flexibility．
