Simulation method of water and underwater body interaction with smoothed particle Hydrodynamics

A real-time simulating method based on smoothed particle Hydrodynamics (SPH) for water and underwater body interaction is proposed in this paper. The force analysis and state update models are established for underwater body and water particles, and a collision detecting method between particles and obstacles is also proposed. The water surface is extracted from water particles based on Marching Cubes for final rendering. Experimental results showed that our method is feasible to simulate interaction of underwater body and water.
