Abstract

Speed of fluid simulation calculations is an important factor for realizing real-time applications in computer graphics. Position based fluids (PBF), which is an incompressible fluid simulation method, has been suggested as a practical method for real-time simulation. Using this method, it is possible to take large time steps; therefore, the cost of calculation can be reduced. However, method is not practical for applications that require high resolution and frame rate because it is necessary to iteratively calculate the density constraints. In this study, we developed a pressure model that replaces the iterative density calculation in PBF to realize faster simulation. First, we hypothesized that problems with incompressibility caused by a small number of iterations can be solved by considering the influence of pressure. Second, we used an alternative pressure model that uses this hypothesis and verified it using simulation. The pressure interpolation model uses the function relating to the distance and the density. The results confirm that compression of the fluid can be suppressed even with a small number of iterations. Finally, by considering the influence of pressure in PBF, it was possible to substitute the proposed model for iterative calculation of the density constraints.
