Abstract: According to the principle of particle system, this paper uses texture mapping, color blending and display list technology to control motion curve of fireworks particle. Refered to three-leaf parametric equation, it makes fireworks particle appear three-leaf form. The size, color and location of three-leaf rose dynamic fireworks renews with time. The particles die, and three-leaf rose dynamic fireworks disappear until the color of fireworks particle is the same as night background. Simulation result shows that three-leaf rose dynamic fireworks can create vivid images and comes up to the real-time requirements.

Key words: particle system, color blending, texture mapping, display list

摘要： 根据粒子系统原理，采用纹理映射、色彩混合、显示列表技术控制烟花粒子的运动轨迹。参照三叶玫瑰参数方程，使爆炸后的烟花粒子在空中呈现三叶玫瑰状，产生的三叶玫瑰动态烟花的大小、颜色、位置随着时间推移不断更新，直至烟花粒子与夜色背景颜色一致时，粒子死亡，三叶玫瑰烟花消失。实验结果表明，三叶玫瑰动态烟花形态逼真，实时性好。
