摘要: 通过对烟雾力场的分析研究,将局部力场和动态力场相结合,用四边形面片代替粒子,采用与纹理结合的方法,让粒子以一定的角速度自转,模拟了烟雾的漩涡、烟雾与障碍物碰撞等场景。实验表明,该方法达到实时性要求,帧率不低于28。

关键词: 烟雾, 模拟, 粒子系统

Abstract: Through the analysis of the smoke field and combining the local field with the dynamic field,some scences are simulated,such as whirlpools of the smog,collisions between smog and obstacles,by replacing particles with quadrilateral surfaces,adopting a way combining with textures and making particles rotate in a certain angular velocity.The experiments show that this method meets the realtime requirements,with the frame rate not less than 28.

Key words: smoke, simulation, particle system
