基于气体动力学和粒子系统理论，本文给出了一种实时生成动态浓烟的方法。算法以球为基本粒子对烟进行造型，采用动态纹理映射技术和透明度扰动方法，来模拟烟的浓淡变化，采用简化物理方法，来描述浓烟的运动。与传统的粒子系统和随机湍流运动模型相比，该算法既正确模拟了烟的行为，又降低了计算复杂性，真实再现了动态浓烟的视觉效果。%The paper presents a method on real-time generation of dynamic dense smoke based on aerodynamics and the particle system theory.It simulates the smoke's shade using dynamic texture mapping and transparency disturbance.In addition,it describes the smoke's movement using simple physical equations.Compared with the traditional particle system and the stochastic turbulence model,it can generate realistic visual effect of dynamic dense smoke,which both accurately simulates the smoke's behavior and reduces the computing complexity.
