document: A hybrid model for smoke simulation A smoke simulation approach based on the integration of traditional particle systems and density functions is presented in this paper . By attaching a density function to each particle as its attribute , the diffusion of smoke can be described by the variation of particles ' density functions , along with the effect on airflow by controlling particles ' movement and fragmentation . In addition , a continuous density field for realistic rendering can be generated quickly through the look-up tables of particle 's density functions . Compared with traditional particle systems , this approach can describe smoke diffusion , and provide a continuous density field for realistic rendering with much less computation . A quick rendering scheme is also presented in this paper as a useful preview tool for tuning appropriate parameters in the smoke model
