摘  要

 自然界中的大多数景物的外形是随机变化的，如云彩、爆炸、浪花、雨和雪等，很难用常规的建模方法及模拟技术来描述。因此自然景物的模拟一直以来都是计算机图形学领域研究的热点和难点。就爆炸模拟而言，因其形状与性质在时间上和空间上的多变性，而更具有挑战性。
 本论文选择爆炸作为模拟的对象，首先分析了粒子产生效果的原理以及介绍基于3dmax软件中的粒子系统制作的过程。然后，分析了爆炸的整个过程和外观特征，初始化新的爆炸粒子的位置属性以及新的粒子产生的位置属性。在整个过程加入重力，风力和阻力以模拟真实场景效果。在毕业设计中完成了爆炸效果以及对此效果进行优化。最后论文对粒子系统制作特效过程进行了总结，以及粒子系统在未来各个领域的展望。

ABSTRACT

Most features of the natural world in the form of random changes, such as: clouds, explosions, spray, rain and snow, and so on, it is difficult to use conventional method of modeling and simulation techniques to describe. Therefore  the simulated computer graphics of the nature has been a hot and difficult area of research . On the simulated explosion, because of their shape and nature in terms of time and space on the variability, and more challenging.
Papers chosen the simulated explosion as the object. First, analysising the effect of particulates on the principle and based on 3dmax particulates in the system software produced by the process. Then, the particle system in accordance with the principles of particle effect of the explosion of the whole process and appearance characteristics, the initial explosion of new particles and the location of the new particle attribute the location attribute. Dynamically change the movement of explosive particles, And give full consideration to the authenticity of the explosion, in the process by adding gravity, wind and obstacles to simulate the real scene effect. Finally, Papers will be conclude for the particle system effects production process : that the general law and the particle system in the future prospects in various fields.

Key words: particle systems, special effects, explosions, simulated
