摘　　要：在总结传统粒子系统理论的基础上,提出了一种基于粒子系统的尾焰实时模拟方法.该方法在渲染过程中使用透明混合技术和billboard技术,并利用GPU的并行处理能力和高速运算能力,在GPU中实现billboard视向变换和透明混合.最后基于DirectX平台,利用VC++进行编程实现了本文提出的尾焰模拟方法.模拟结果表明,此仿真方法具有很高的逼真度和实时性.By researching and summing up traditional particle system theory, a simulation method of trail flame based on particle system is provided. This method applies alpha-blend technology and billboard technology, and also makes use of parallel operation ability and high-speed operation ability of GPU, and realizes view transform of billboard in GPU. At last, based on the DirectX platform, the simulation method of trail flame which is provided in this paper is realized by VC＋＋, and simulation results show that the simulation method in this paper is of high fidelity and real-time performance.
