| 摘 要： | 在分析粒子系统实现原理的基础上,基于Vega提出了一种在大型场景漫游系统中实时模拟雨、雪的方法.基本思想是基于Vega特效模块粒子属性的设置,采用一种始终面向视点的多边形来表示雨、雪粒子模型.试验结果表明,该方法交互性强,能够有效地再现三维场景中的降雨、降雪景象,在实时交互漫游的前提下表现出较强的真实感.

| Abstract: | A method for simulating real-time rain or snow in a big scene was presented based on special effects module of Vega software.The rain and snow models were simulated by viewport-oriented polygons.The results of experimentation have proved that this method is more effective in the representation of rain and snow in 3D scene,and is realistic on the premise of satisfying basic needs of real-time interactive navigation. |
