user-controllable fluid simulation model for computer graphics

提出了一种自适应、可控的基于粒子的计算机图形学流体仿真方法。首先，我们提出了一种新的基于自适应采样粒子法的流体片保存算法。该方法是一种扩展的流体隐式粒子（FLIP）模型，采用各向异性位置校正来改善粒子间距。接下来，我们提出了一种利用目标形状来控制流体行为的交互式方法。为了实现期望的运动，我们通过使用使用Navier-Stokes方程的控制粒子来定义附加力。控制粒子是从用户选择的流体区域生成的，并且使用参照目标形状的形状匹配方法依次确定它们的行为。我们的方法使人们能够交互式地模拟流体动画，流体动画根据物理原理逐渐变形为目标形状。

We developed an adaptive and controllable particle-based fluid simulation method for computer graphics. First, we developed a new algorithm for preserving fluid sheets with an adaptively sampled particle method. This method is the extended FLIP(Fluid-Implicit Particle) model with an anisotropic position correction to improve the particle spacing. Next, we propose an interactive method to control fluid behavior by using a target shape. To achieve the desired motion, we define the additional forces by using control particles employing the Navier-Stokes equation. Control particles are generated from a fluid area chosen by the user, and their behavior is sequentially determined by using a shape-matching method referring to the target shape. Our method enables one to interactively simulate fluid animation, which is gradually deformed to the target shape based on physics.
