Modeling method of motorial solid-water interaction based on SPH

A real-time simulating method based on SPH for interaction between motorial solid and water was proposed. This method took falling solid as an example, and particlelized it as well as water. The force analysis and state update models were established for solid and water particles, and a collision detecting method between particles and obstacles was proposed also. The water surface was extracted from water particles based on Marching Cubes for final rendering. Experimental results show that the method is realistic, and can achieve real-time frame rate when particle amount is less than 6000.
