Abstract:This paper presents a physically based approach for real time fountain simulation based on fluid dynamics and particle system. Unlike traditional method which need solve complex Navier Stokes equations, the authors adopt a special case of these equations and a simple dynamics equation of particles, the user can see the fountain flow changes in real time by adjusting some parameters.Metaballs are taken as particles and a ray tracing algorithm based on Bezier Clipping is adopted to obtain visually aesthetic fountain flow. The model is very simple and can be easily integrated into commercial 3D animation software systems.
Keywords:Computer animation  fountain  fluid dynamics  particle system  metaball
