Abstract
GPU-based fluid animation is a hot topic in many applications such as films, cartoons and games. As the flow phenomena contain highly complex behaviors and rich visual details, it is necessary to explore the intrinsic multi-scale property in fluid animation. In this paper, we present a multi-scale fluid animation method on GPU. Our method is designed to animate fluid details of grid and sub-grid scale with high efficiency. In our method, the motion of liquid surface is obtained by solving Navier-Stokes equations and Level Set equation while the dynamics of fluid sprays are dominated by SPH solution. The interaction between liquid surface and sprays is modeled by a two-way coupling algorithm which can be executed efficiently on GPU. From the results of the experiments, we can reach the conclusion that the proposed GPU based acceleration method can improve the processing speed of the multi-scale fluid animation significantly while getting interesting details.
