> 中文摘要: 本文讨论了一种用粒子系统模拟喷雾效果的方法.该方法应用于实际电脑动画广告中,制作了喷撒农药的片段.喷雾体是一个粒子系统,每个粒子是一个具有较高透明度的正方形微片.喷雾体随喷口在空间运动.微片的大小、透明度和运动学参数的规定决定了喷雾体的形状和视觉效果.喷雾体所占有的象素的值是和该象素上的视线相交的所有微片的亮度决定的.本文提出的模拟模糊物体的方法,可推广到对其他模糊物体,如烟、水、云等的模拟.
Abstract:A method of simulation of spray using particle systems is presented in this paper. The spray body is a particle system composed of square pieces with high transparency. The spray body moves in space with the spray mouth. The shape and visual effect ofthe spray body are determined by the size, transparency and Kinematic parameters of thesquare pieces. All pieces intersected with one sight ray contribute to corllputing of the pixel value of the sight ray. This method is generally applicable to simulation of other fuzzyobjects sllch as smoke, water and cloud.
