“…For particle-based fluid animation, most of the research work focuses on avoiding the loss of details in fluid deformation, such as [15][16][17]. Wang et al [18] proposed a new method combined with the Marching Cubes and free surface algorithm to extract the fluid surface and used adaptive surface tension combining the wave-particle equation to show the details of fluid surface. For grid-based fluid animation, Thürey et al [19] also focuses on fluid control technique instead of detail preserving of fluid surface and proposes a new fluid control technique that used scale-dependent force control to preserve small-scale fluid detail.…”

In digital production environments, high-quality visual effects play a key role in our mobile device such as game and film. The simulation of fluid animation with free surface is an important area in computer graphic. However, the tracking of fluid surface is a challenging problem because of its instability. In this paper, a coupled grid-particle method for fluid animation surface tracking and detail preserving is proposed. Firstly, based on the nonequilibrium extrapolation method, we design a novel method for reconstructing distribution functions (DFs) of interface grids of lattice Boltzmann method (LBM) and couple the reconstruction method with LBM and volume of fluid (VOF) to track the free surface, which can obtain the accurate surface. Secondly, in order to avoid the loss of details caused by weaknesses in the traditional LBM-VOF method, we design a coupled grid-particle method that not only makes full use of the advantages of the coupled grid-particle method but also realizes the two-way coupling between grid method and particle method. Furthermore, for achieving the real-time requirements of fluid animation, we use GPU parallel computing to accelerate the simulation and use an improved screen space fluid (SSF) rendering method for realistic rendering. The various experiments show that this work can track the fluid surface with high precision and preserve the details of the fluid surface, and it also achieves good real-time performance in large-scale fluid simulation.

Abstract-Re-simulating a 3D fluid result from video while retaining and rendering details is significant in practice, which still remains a difficult task in spite of rapid advancements in this field during the last two decades. Physically driven models can be easily extended to handle fluid, yet they are unable to preserve surface details like breaking waves without the expense of increasing particle densities. This paper proposes a hybrid particle Lattice Boltzmann Model for Shallow Waters (LBMSW) coupling method to simulate fluid with finer details real-time from video. To preserve re-simulation surface details, we couple the detail particles with the distribution function of the LBMSW model. To improve the time performance, we use only surface to re-simulate. Experiments show that the proposed approach can obtain a realistic re-simulation products from video example in several challenging scenarios and we provide qualitative evaluation to the method.
