| 摘 要： | 作为自然场景中特殊效应的一部分,火焰效果有着重要的作用。设计了基于粒子系统的火焰模型,讨论了模型参数变化对显示效果的影响,为了增加粒子系统的灵活性,引入空气速度场模拟火苗跃动现象,采用改进的高级粒子系统思想建立了粒子系统的四层层次结构,实现了具有较强真实感和实时性的火焰效果。

| Abstract: | As an important part of the so-called special effects in the natural sceneries, the fire effects play a key role in the overall performance. A fire model based on particle system was proposed, and the influence of parameters selection on the displayed result was explored. In addition, the air velocity field was designed to exhibit features specific to animated fire. A four-layer hierarchy was designed based on the advanced particle system. A nice effect of real-time fire was got. |
