Real-time 2D fluid simulation on GPU

The real-time 2D fluid simulation on GPU was achieved by using the high-level language for programmable graphics hardware-C for Graphics. The semi-lagrangian method was used in solving Navier-Stokes equation to obtain the stability of fluid simulation. Vortcity confinement was imported to make up the numerical dissipation in the simulation of fluid. Texture was used to store the data used in the computation and vector quantity was stored to the four channel of a texture unit which decreased the amount of computation. The test results demonstrate that thefluid simulation of this paper is of great efficiency.
