In this paper, a new simulation model that rapidly generates dynamic open waves on a computer is proposed. We derive an efficient equation for simulating sea and swell waves and their composites. A composite wave system which can simulate swells in deep and shallow water is first derived. Trial results are given to show the feasibility and effectiveness of the proposed model.

Keywords: geometric modeling, wave simulation, long-crested wave theory, small-amplitude wave theory
