摘要: 介绍了二维流体和三维流体动画方法。流体动画制作分为两步:流体表面建模和流体绘制。二维流体建模主要采用参数建模方法,基于傅立叶变换原理,合成波动的二维流体表面。三维流体建模一般基于Navier-Stokes流体方程,利用流体内部的速度建立流体表面的方程。流体绘制主要采用光线跟踪方法。流体动画的挑战和发展方向在于:流体动画控制、实时绘制、细节表现。

Abstract: The fluid animation,including 2-D and 3-D fluid animation,is introduced in this paper.The process of fluid animation producing can be divided into two steps including fluid surface modeling and fluid rendering.2-D fluid modeling mainly adopts the parametric modeling method based on Fourier transform to compose the fluctuant 2-D fluid surface.3-D fluid modeling mainly bases on the Navier-Stokes fluid equation and uses the internal rate of the fluid to establish the equation of fluid surface.Fluid rendering mainly adopts ray-tracing method.The challenges and future works of fluid animation may include the fluid animation control,real-time rendering,detail exhibiting and so on.
