我们提出了一个算法，在三维场景中的流体模拟与障碍物表示为隐式表面。基于光滑粒子流体动力学方法进行流体模拟，通过引入一种新的粒子运动模型来定义流体粒子在障碍物附近的行为，该模型专用于隐式表示。为了在图形处理单元上实现有效的并行化，我们采用网格多项式方法来表示隐式定义的障碍。该方法充分利用了隐式表示的平滑性、形状建模和变形对象的表达等特性。
We propose an algorithm for fluid simulation in three-dimensional scenes with obstacles represented as implicit surfaces. The fluid simulation is performed based on the smoothed particle hydrodynamics method and the behavior of fluid particles in the vicinity of obstacles is defined by introducing a new model of particle motion specific to implicitly representation. For effective parallelization on the graphics processing units, we apply the grid of polynomial method to express the implicitly defined obstacles. The proposed method takes advantage of the properties of implicit representation such as smoothness, shape modelling and the expression of deforming objects.
