Real-time Particle-based Method for Simulating Fluid Flows on Surfaces

Abstract

Physically based fluid simulation is one of the most important research topics in computer graphics.Although many methods have been developed that use 3D or 2D grids to simulate fluids,there are few methods for simulating fluid flows on surfaces.We present a real-time particle-based simulation method for the flows on surfaces.The surfaces are parameterized in a 2D parameter domain and physical quantities of particles are calculated in the parameter domain.The flows are simulated by updating the physical quantities of the particles,and the simulation is accelerated with a GPU.Our method simulates the fluid flows of 30,000 particles in real-time.
