In this paper, we propose a novel method of interactive fluid simulating based on SPH, and implement it on CUDA (Compute Unified Device Architecture). Firstly we use SPH (Smoothed Particle Hydrodynamics) theory to simulate the motion of fluids. Secondly we propose an interactive method between fluid and rigid objects. We treat the rigid objects as two different types, static one and dynamic one. We deal with the two types in separately suitable ways in order to enforce their motion similar to the real world. By taking advantages of CUDA which are greatly effective for large scale numeric computation in parallel, our simulation achieves real time with low cost.
