摘    要:喷泉效果可以增强三维场景的真实感。论文用粒子系统作为喷泉建模的方法,通过动力学原理模拟水流的运动,对水流中粒子的运动采用循环式的重复使用,从而大大提高程序运行效率。利用Direct3D对粒子绘制的支持,通过Shader编程充分挖掘GPU的处理能力,并对水珠粒子进行多样化的高效绘制。通过CPU与GPU相互结合的方式,既保证了喷泉效果的真实感,又有较高的运行效率,也能满足系统实时性的速度需求。

关 键 词:GPU  粒子系统  喷泉  实时绘制

Abstract:The effect of fountain can consumedly enhance the realistic characteristic of three dimension scenes.We construct our fountain model based on particle system,simulate the fountain streams based on motivity theories,and consumedly improve the running efficiency of the program through cyclic using the moving stream particles.We make use of the ability of Direet3D for the particle rendering,deeply explore the computation ability of GPU through shader programmlng,and effectively render the water droplets in many ways.Combined with GPU and CPU,realistic characteristic of fountain and efficiency of program are achieved and also satisfy the real time running requirement of the system.
Keywords:GPU
