Abstract(in Japanese) (See Japanese page)
Abstract(in English) We propose a unified method to simulate multi-phase fluids, including gases, liquids, and solids in computer graphics. Our method involves introduction of a simple step function called the density function with advection to track the free surface. Although advection of functions that vary abruptly, such as the step function, causes numerical problems, we solve them by the CIP (constrained interpolation profile) method and can track the free surface with sub-cell resolution without the time consuming reinitialization process required for the level set method. Furthermore, by applying the CIP-CUP (combined and unified procedure) method, we can treat both of incompressible and compressible fluids in a unified manner. Our method can simulate the behaviors of gases, liquids, solids, and interactions among them at the same time as well as surface tension. Its implementation is more straightforward than the level set method because it is not necessary to take account of phases differences. We report the results of several demonstrations of fluid simulation with the effects of bubbles produced by our method.
