到目前为止，一些CG研究人员已经模拟出了令人印象深刻的海浪。最近，其他研究人员成功地利用大量粒子模拟了瀑布。然而，具有复杂表面的水流的视觉模拟，例如山溪和湍流，由于其复杂的行为模式，仍然是一个具有挑战性的问题。有效的水流模拟方法，预计有能力代表以下显着的行为视觉特征的水：一个池的外观，避障流，流畅的流，流入一个开放的空间，碰撞和汇合的流动和飞溅的发生。
在本文中，我们提出了一种新的类型的基于粒子的模拟方法，复杂的水流，这不是基于严格的流体动力学，而是归类为“准物理为基础的”模拟方法的基础上构建的算法方法。我们首先提出了一个简单的行为模型的“水粒子”。接下来，我们提出了一种方法，用于生成CG图像的水流从一组水粒子。最后，我们展示了我们的方法的能力，通过模拟的几个例子。
Several CG researchers have simulated impressive ocean waves so far. Recently, other researchers have succeeded in simulating waterfalls by employing a mass of particles. However, visual simulation of water currents having complex surfaces, such as mountain streams and turbulent water, still remains a challenging problem thanks to their complicated patterns of behaviour. Effective simulation methods for water currents are expected to have abilities to represent the following remarkable behavioural visual features of water: the appearance of a pool, an obstacle avoidance flow, a fluent flow, a flow into an open space, the collision and the confluence of flows and the occurrence of splashes.
In this paper, we present a new type of particle-based simulation method for complex water currents which is not based on strict fluid dynamics but rather classified into a ‘quasi-physically-based’ simulation method constructed on the basis of algorithmic approaches. We first present a simple behavioural model of a ‘water-particle’. Next, we propose a method for generating CG images of water currents from a set of water-particles. Finally, we demonstrate the ability of our method by showing several examples of the simulation.
