Fast Animating of Fluid Simulation

摘要：

Existing grid-based techniques cannot suit for highresolution fluid simulation due to the high computational cost. This paper presents a novel modified linear interpolation(MLI) upsampling method for animating details-abundant fluids quickly. Our method runs on a high-resolution grid while creating a divergence-free velocity field on a coarse grid to speed up the calculation. Different from previous work, we use a novel MLIupsampling operator to reconstruct a fine velocity field from the coarse divergence-free velocity field. The upsampled velocity field is kept divergence-free without solving Poisson equation on the fine grid. We provide several examples to demonstrate that our method is efficient and effective, and it is ideal for CG application where visual detail and speed are essential.
