摘　　要：W.T.Reeves提出的粒子系统模型是模拟不规则模糊物体最成功的一种图形生成方法。为了模拟出效果逼真的烟花,文中采用了粒子系统模型对烟花进行动画设计。在深入研究粒子系统的基本理论和对烟花燃放细节的分析的基础上,建立了基于粒子系统的烟花模拟模型,设计了一种五彩缤纷的烟花动画算法。在编程上,结合了VC++编程语言和OpenGL的纹理映射技术,降低了渲染粒子的复杂度。实验结果表明,该算法快速、简单,视觉效果逼真,可以方便地应用到游戏和影视动画中。In the methods of irregular object modeling,the particle system model which was proposed by William T.Reeves is recognized as the most successful in the graphics generation algorithms.In order to simulate realistic fireworks effects,use the particle system model to design animation of fireworks.Establish a fireworks simulation model based a particle system in-depth study of the basic theory of particle system and the analysis of the fireworks booming details,and design an animation algorithm of multicolored fireworks.In the programming,combines VC ＋ ＋ programming language and OpenGL texture-mapping technology to reduce the complexity of rendering particles.Examples illustrate that algorithm is fast,simple,and has good reality,so can be applied conveniently to games,film and television animation.
