Surface Reconstruction for Particle Simulation Using Level Set Method

A particle-based method is one of the most commonly used methods for fluid simulations. It has certain advantages over other fluid simulation methods; for example, it is easy to simulate irregular and complex fluid motion with topological changes. However, the surface reconstruction for particles remains a challenging problem. In this paper, we propose a surface reconstruction method for moving particles whose motion data are given by a particle-based simulation method. Our method utilizes a level set method to reconstruct a surface because the level set method enables the surface to change its topology free according to the irregular arrangement of particles. Moving particles’ data such as positions and velocities given by a gridless particle-based method are effectively used in the level set method executed on a grid space. As a result, a suitable surface is reconstructed so as to follow the moving particles with topological changes. Besides, our method makes isolated splash particles to appropriately contribute to the surface reconstruction. Some experimental results show the useful performance of our method.
