摘　　要：针对烟雾建模方法无法应用于复杂环境的现状,提出一种在复杂环境中实时模拟烟雾扩散的方法,即对于在烟雾建模阶段采用基于粒子系统建模方法的情况,在烟雾可视化阶段利用Java3D独有的碰撞检测功能,对烟雾与障碍物进行碰撞检测和处理,解决了烟雾建模方法无法应用于复杂环境的问题.实验证明,该方法可与基于粒子系统的烟雾建模方法结合使用,实时表现烟雾在复杂场景中的扩散现象.与不规则物体建模方法相结合,可以近似模拟这些物体在复杂环境中的扩散现象.Aiming at the situation that the smoke modeling methods can＇t be applied to complex environment, a real-time simulation approach of smoke pervasion in complex environment was proposed. The particle system modeling method was adopted in the stage of smoke modeling, and the particle collision detecting function of Java3D was used to deal with the collision detecting between smoke and barrier in the stage of smoke visualization. The experimental results show that this approach can be combined with smoke modeling method based on particle system to show real-time smoke pervasion in complex environment. The present approach combined with the irregular object modeling method can be used for simulating approximately the pervasion phenomenon of the object in complex environment.
