摘 要:
利用粒子系统的基本原理，将飞机水汽尾迹定义为一系列具有生命周期的不规则、随机分布的粒子，给出相应的动力学模型和算法，实现飞机水汽尾迹的仿真。针对仿真过程中色彩转换相对困难的问题，采用查询预先存储的RGB颜色分量的各级强度值的方式，结合DirectDraw的换页技术，加快了算法的运行速度。[著者文摘]

Abstract:
To realize the simulation effect of plane vapor wake,this paper defines it as a series of anomalous and random distributing particle with lifecycle based on the basic principle of particle system, presents corresponding dynamics model and arithmetic. To resolve the problem of color transformation in simulation process, this paper improves the speed of arithmetic by the way of query all level intensity of RGB color quantity stored in advance and in the terms of DirectDraw page flipping.[著者文摘]
