一种基于改进的粒子系统的烟花模拟

粒子系统是用来模拟不规则运动物体的一种比较有效的方法。该文首先阐述了粒子系统的基本原理，对烟花粒子系统的基本模型和燃放原理进行了分析。然后利用粒子系统的基本原理，结合烟花燃放的具体特点，建立了基于粒子系统与纹理映射的烟花动态模型．模拟了烟花从上升到爆炸，再到消失的过程。在已建好的模型中对烟花模型进行了改进，使得单个烟花在绽放后再次绽放成其他形状．从而提高了用粒子系统模拟烟花的灵活性。

Fireworks Simulator Based on the Particle System Improved

Particle system is an effective method in simulating irregular moving object. First,This pape introduces the principle of particle system and makes a further study on the basic model of firework particle system and the principle of letting off fireworks.Then set up a model based on the particle system and texture mapping, making use of the basic idea of particle systems, combined with the specifci characteristics of fireworks,simulating the fireworks from up to an explosion,then the process of disappearing. Then we modify the model already built to make the firewok blooming into other shapes again. It can improve the flexibility of simulated fireworks.
