水流动画模拟方法探讨

目前,对于水流动画模拟的研究已经取得了相当丰富的成果。基于物理模型的流体动画模拟的研究,需要计算流体力学和计算机图形学的交叉融合,根据其研究的背景与内容的不同,可分为两种类型。基于物理模型的流体动画模拟中描述流体运动的方法主要有两种,一种是Euler方法,另一种是Lagrange方法。Euler方法的主要缺点是难以处理流体的细节,Lagrange方法的优点就是能很好地表现流体的细节。由于Euler方法和Lagrange方法的这些特点,如果发展这两种方法的综合方法,则可取长补短。

Probe into the Methods on Water Flow Animation

At present,the study on water flow animation has been productive.The study on the simulation of water animation based on phisical model requires the amalgamation of numerical fluid dynamics and computer graphics.It can be classified into two kinds according to the differences between background and content.There are two ways to describe the movement of fluid body in the simulation of fliud animation based on phisical model: one is Euler method,another is Lagrane method.The main disadvantage of Euler method is difficult to deal with the details of the fluid bodies,while that is just the advantage of Lagrane method.Due to their own specific features,they can make up for each other if we find the coupling of the two methods.
