摘　　要：计算机动画是应用计算机技术制作动画的艺术,是计算机图形学和动画的子领域。计算机动画采用连续播放静止图像的方法产生物体运动的效果。基于此,文中采用粒子系统去产生一幅图像所需的各个像素的帧,并将其绘制在屏幕上。文中通过对烟花系统模型的研究,提出将烟花的爆炸效果进行控制的模拟方法。基本原理是对爆炸瞬间烟花粒子属性的控制,并运用纹理映射对烟花粒子进行绘制。达到了对烟花轨迹进行控制的预期效果。Computer animation which is the subfield of computer graphics and animation is the art of the use of the computer technology. Computer animation uses the method of continuous playing static image to produce the effect of movement object. Based on this, use par- ticle system to produce an image which is needed for each pixel of the frame, at last drawn this frame to the screen. Through the research of the fireworks system model, put forward the simulation method of the controllable shape of the fireworks. The basic principle is the control of the attribute of firework particle instantly in the explosion ,using texture mapping to draw the firework particle. And get expec- ted effect of controllable trajectory of fireworks.
