ParticleEngine_demo.rar - 粒子系统的源码，在图形学中用处很大
Particle System可以说是一种基于物理模型来解决问题的方法
子运动（变化）的规则可以很简单也可以很复杂，这取决你所模拟的对象。举例来说，在对FireWorks（烟火）的模拟中，我们可以让烟火由上百个小的粒子组成，每个粒子都具有以下一些属性及其规则（对各个属性施加不同的规则，就可以获得不同形态的烟火）：

ParticleEngine_src.rar - The concept of particle effects is very simple. Particle effects can be used to simulate fire, fireworks, water fountains, snow, rain, explosions and many other things. The effects are created by creating a definite number of particles. Depending on the need for performance and realistic appearance, the number of particles can range from 50 to thousands. Each particle has its own location, size, velocity, color, life and image. The particle engine controls the particles and makes them react according to the rules of the particle .,2008-09-24 22:40:52,下载18次
