Abstract: This paper introduces the rendering to texture technology, based on the analysis of the existing fireworks simulation methods. It renders the tail flame in the fireworks movement process through drawing the screen texture repeatedly, and combines with the method of particle system. All these make the fireworks simulation speed has been effectively promoted. Finally the paper simulates the tree, dolphin in the shape of fireworks with this method and mathematical model of the curve. Experimental results show that when simulating the fireworks with more number of cases, this method can reflect better real-time performance comparing with the traditional one.

摘要： 在分析现有的烟花模拟方法的基础上，引入渲染到纹理技术。以多次绘制屏幕纹理的方式，渲染烟花运动过程中产生的尾焰，结合粒子系统方法，使得烟花的模拟速度得到了有效提升；用该方法以及曲线数学模型模拟出了树形、海豚形状的新型烟花。实验结果证明，该方法在模拟烟花数量较多的情况下，较传统方法能够体现出更好的实时性。
