This paper presents a real time cartoon smoke simulation algorithm 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 very little particles are needed to generate the smoke density field.To get the cartoon effect

primitives designed by animators are mapped to the scene according to the smoke density during the rendering process.Experimental results show that the algorithm is simple and effective to achieve real time cartoon smoke simulation.
