OPENGL喷泉效果的演示，主要是复杂粒子运动轨迹计算及粒子生命周期计算同时还有3D场景的角度变换-OpenGL fountain effect of the display, is a complex calculation of particle trajectories and calculating particle life cycle along with 3D scenes perspective transform

四阶龙格－库塔法模拟粒子三维空间轨迹，需给出立场函数,3D simulation of particle dynamic trajectories by Fourth-order Runge- Kutta method

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
