A Hybrid Model for Smoke Simulation

A smoke simulation approach based onthe integration of traditional particle systems and density functions ispresented in this paper. By attaching a density function to eachparticle as its attribute, the diffusion of smoke can be described bythe variation of particles' density functions, along with the effecton airflow by controlling particles' movement and fragmentation. Inaddition, a continuous density field for realistic rendering can begenerated quickly through the look-up tables of particle's density functions.Compared with traditional particle systems, this approach can describesmoke diffusion, and provide a continuous density field for realisticrendering with much less computation. A quick rendering scheme is alsopresented in this paper as a useful preview tool for tuning appropriateparameters in the smoke model.
