Real-Time Simulation of Fluid Scenes by Smoothed Particle Hydrodynamics and Marching Cubes

Abstract EN

Simulating fluid scenes in 3DGIS is of great value in both theoretical research and practical applications.

To achieve this goal, we present an algorithm for simulation of fluid scenes based on smoothed particle hydrodynamics.

A 3D spatial grid partition algorithm is proposed to increase the speed for searching neighboring particles.

We also propose a real-time interactive algorithm about particle and surface topography.

We use Marching Cubes algorithm to extract the surface of free moving fluids from particles data.

Experiments show that the algorithms improve the rate of rendering frame in realtime, reduce the computing time, and extract good real effects of fluid surface.
