摘　　要：基于粒子系统方法,在Vega Prime平台上模拟了火箭飞行过程中的尾焰特效及推进剂泄漏事故烟雾特效,重点介绍了粒子的生成、属性和运动,并以某火工品测试厂房火灾扑救情况为例,探讨了粒子系统的控制技术。试验结果表明,场景逼真度高,实时性强,取得了较好的渲染效果。Based on the particle system,special effects of space launch such as the rocket plume and the propellant smoke are simulated,focusing on the generation,properties and motion analysis of the particle. Moreover,the control technology of particle system is discussed by the example of a fire fighting case inside the pyrotechnics test building. The result shows that the system has a high fidelity and realtime performance.
