摘　　要：烟花的仿真对于烟花燃放编排、动画游戏、影视特效等有着非常重要的应用.基于粒子系统可以进行烟花的模拟,但粒子数较多时常常绘制速度较慢.引进最新发展的图形硬件加速绘制技术,提出了一种基于GPU(GraphicProcess Unit)粒子系统的烟花绘制技术,并构架实现了一个实时的烟花仿真系统,实现了不同烟花燃放场景的真实感仿真.The simulation of fireworks has many applications in firework choreography, game animation, special effects in movies, etc. Firework can be simulated by particle systems, but the rendering speed is often slow since the number of particles is too large. The latest graphic hardware-accelarated rendering technology was introduced to accelerate rendering process, and a GPU-based particle system for firework rendering was presented, and a real-time firework simulation system was implemented. The results of simulation show that realistic simulations of different firework scenarios can be achieved.
