【摘要】 文章设计了粒子系统火焰模型,详细讨论了模型中粒子的属性及其变化,实现了具有较强真实感的颜色变化和动态摇曳等火焰特性,采用纹理映射和视线跟踪技术进行三维火焰渲染;同时,采用了层次化的编程结构,用以提供简单实用的交互性火焰模拟。最后提供了篝火、烛火、火箭尾焰以及战场火焰模拟的效果图。更多还原

【Abstract】 A fire model based on particle system is proposed in this paper.It firstly discusses in detail paticle’s at-tributes and their evolvements,then emphasizes the color variation and dynamic wavering of the fire.Secondly,texture mapping technique and sight-tracing strategy are used when rendering the fire.Thirdly,a two-level program structure is designed to provide a simple interactive fire model.Lastly,images of several fire models,such as campfire,candle fire,missile trail fire and battlefield flame ,are provided in section5.更多还原
