【摘要】 本文给出一个基于流体物理模型和粒子系统的快速卡通烟雾模型。通过 Navier-Stokes 方程建立烟雾流体场的物理模型,以保证运动轨迹的真实感。为粒子属性引入了浓度函数和作用半径,从而只需少量粒子就能快速获得浓度场分布。为了实现卡通化效果,使用卡通图元进行纹理贴图。试验证明该系统高效快速,能实时生成自然生动的卡通烟雾效果。更多还原

【Abstract】 This paper presents a fast cartoon smoke simulation model based on fluid dynamics and particle system.The smoke path is controlled by the Navier-Stokes equation to get an impressive effect.The density function and working radium are added to the particle properties,thus much less panicles are needed to show the smoke density filed.Cartoon primitives are mapped to the scene during the rendering process,and then we get the cartoon style effect.Experiment results show that our system achieves real-time cartoon smoke simulation effectively.更多还原
