Abstract

To improve the reality of river visual in inlandriver ship simulator and meet real time of rendering, a method was introduced based on concept and property of steam function for solving velocity field of river surface. The method generated values of stream function with real bank of river by using the algorithm of inverse distance weighted. The velocity can be generated effectively, and the algorithm can be suitable to solve velocity field of river branch channel. Simulation results show that the proposed method can reflect the real distribution of river velocity, and satisfy the demand of real time,which improves the environment reality of river visual in inlandriver ship simulator.

Key words： ship simulator; inland-river; stream function; simulation
