Abstract

This paper presents a new method for animating particles on an arbitrary triangular mesh starting from a fluid flow velocity field. The velocity field visualization with particles allows for the production of new special effects. An attraction constraint is introduced to correct a particle's velocity so its trajectory remains near the surface. A repulsion constraint is also used to ensure a better distribution of particles on the surface. Our velocity field is obtained by physically-based heuristics, implemented with a chain model. Our method is robust and yields good results, in particular for interactive simulations, even for systems with several thousand particles.
网格上基于颗粒的流体流动可视化
本文从流体流速场出发,提出了一种在任意三角形网格上绘制粒子动画的新方法。速度场可视化与粒子允许生产新的特殊效果。引入引力约束来修正粒子的速度,使其轨迹保持在表面附近。排斥力约束也用于确保颗粒在表面上的更好分布。我们的速度场是通过基于物理的启发式算法获得的,用链式模型实现。我们的方法是鲁棒的,并且产生了很好的结果,特别是对于交互模拟,甚至对于有几千个粒子的系统。
