Hybrid Expression in Fluid Animation
Liu Youqua · Computer and Digital Engineering · 2013
The physically based fluid animation is one of the hottest topics in computer graphics.However,no matter Euler method,SPH or LBM method are time consuming since they always need to solve the complex nonlinear equations.Because each method holds its own advantages and disadvantages on fluid details catching or performance,in recent years many researchers turn to hybrid methods to balance the efficiency and detail expression.This paper tries to summarize the available different hybrid methods.As we point out that for different forms within the fluid simulation,different strategies should be used for some very specific purpose.And the difficulty of hybrid expression is how to maintain the consistency across the interface of these different methods to avoid computation problems.Further research will focus on the fusion of different methods with conservation satisfied across the interface.
