Abstract:

This paper presents a highly effective method of modeling and rendering based on LBM (Lattice Boltzmann method).Firstly,the LBM model based on shallow water equations is adopted to model the fluid volume and calculate the surface height field,and we simulate the Dam Break successfully.In addition,the Velocity field Equations are reduced and Denseness field Equations are added to improve the model of smoke,after which the GPU acceleration technology is adopted to achieve realistic rendering of smoke.

Key words: Lattice Boltzmann method;shallow water equation;free surface;fluid simulation
