摘要: <b<目的</b< 文中了说明三维地形的模拟是进行室外可视化系统开发的一个必不可少的工作。 <b<方法</b< 文中提出了一个利用粒子系统的方法来模拟三维地形中瀑布的运动和汹涌直下。 <b<结果</b< 通过粒子作用范围及浓度的变化模拟瀑布的运动,介绍了粒子的表示和粒子系统的一般原理。 <b<结论</b< 给出了一种基于粒子系统的快速绘制三维地形中瀑布的方法。

Abstract: <b<Objective:</b< 3D Terrain simulation is a necessary task in the development of outside visual sysytem. <b<Methods:</b< In this paper, a method of particle system is presented to simulate waterfall movement. <b<Results:</b< Waterfall movement is simulated through the variance of particle effect and density functions.Particle present and particle system theory is described first. <b<Conclusion:</b< This a method based on particle system to draw a fast 3D terrain is introduced.
