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模拟方法。首先，我们提出了一种新的基于自适应采样粒子方法的流体层保存算法。这种方法是扩展的Flip(流体隐式粒子)模型，通过各向异性位置校正来改善粒子间距。接下来，我们提出了一种通过使用目标形状来控制流体行为的交互方法。为了实现所需的运动，我们使用控制粒子来定义附加力，该控制粒子使用Navier-Stokes方程。从用户选择的流体区域产生控制粒子，并且通过使用参照目标形状的形状匹配方法来顺序地确定它们的行为。我们的方法使得人们能够交互地模拟流体动画，这些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.
