摘要
自然景物雨的模拟,在计算机游戏、三维动画、影视及广告中有着广泛的应用。粒子系统是模拟雨的一种有效方法。但是粒子系统使用随机生成的粒子以及粒子属性来模拟雨,而真实的雨粒子往往不是随机分布的。概率论与随机过程的理论研究和实际应用表明,类正态分布在实际的自然现象与社会现象中分布最为广泛,云模型是模拟生成类正态分布的有力工具,基于云模型控制粒子系统的粒子生成、属性的改变能够更真实地模拟自然雨的生成,具有更逼真的效果。
The natural scenery rain simulation is widely used in computer games, 3D animation, film TV and advertising. Particle system is an effective method in rain simulation. However, the particle system uses randomly generated particles and particles attribute to simulate the rain, but the real rain particles are often not randomly distributed. The theoretical research on probability theory and random process and the practical applications show that the class normal distribution is most widely distributed in actual natural phenomenon and social phenomenon, cloud model is a powerful toot in simulating class normal distribution, controlling particle generation and particles attribute alternation of the particles system based on the cloud mode will simulate the natural rain more realistically, and has more fidelity effect.
