摘要
模拟飞机飞行喷射尾焰的过程能提高虚拟战场场景的逼真性。粒子系统是迄今为止模拟火焰、尾焰这类不规则模糊物体最为成功的一种算法。首先介绍了粒子系统的基本思想,然后根据其原理对飞机尾焰进行了建模,给出了尾焰的定义,分析了尾焰粒子的初始化、活动及消亡的情况,并在最后给出了实验结果。
Simulating the process of plane's tail fire can improve the virtual scene fidelity. Particle system is deemed to one of the most successful arithmetics, which simulats a class of irregular and fuzzy object by far. Firstly, this paper introduces the general theory of the particle system. Then, it constructs models of a plane tail fire based on the particle system, presents the tail fire's definition, and analyzes the partide's initialization,motion and fade. Finally, it gives the simulation result.
