本文的主要贡献是以线元为基本造型单位，运用动力学原理模拟瀑布的运动轨迹[9]，结合层次包围盒技术和建立聚类树加速粒子与障碍物之间的碰撞检测，并采用逐渐淡化融合的方法绘制粒子，形成了具有真实感的实时瀑布飞溅的效果。-Contribution of this article is based on the line for basic modeling unit, use the dynamics simulation trajectories of waterfall [9], combined with hierarchical bounding box technology and establishment of clustering trees accelerated collision detection between particles and obstacles, and slowly fading fusion method is used to draw the particles, forming a realistic real-time waterfalls splash effect.
