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，我们开发了一种新的算法保持流体片的自适应采样粒子方法。该方法是对FLIP（Fluid-Implicit Particle，流体隐式粒子）模型的扩展，通过各向异性位置修正来改善粒子间距。接下来，我们提出了一个交互式的方法来控制流体的行为，通过使用一个目标形状。为了实现所需的运动，我们定义的附加力，通过使用控制粒子采用Navier-Stokes方程。从用户选择的流体区域生成控制粒子，并且通过使用参考目标形状的形状匹配方法来顺序地确定它们的行为。我们的方法使一个交互式地模拟流体动画，这是逐渐变形的目标形状的基础上的物理。

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.
