摘要

针对内河船舶模拟器河流视景中河流流动不够真实、要求实时渲染的问题，采用基于流函数概念和性质求解河流表面速度场的方法进行河流建模和实时渲染.该方法利用河道的真实边界数值，采用反比例插值算法求解河流表面各点流函数数值，有效地获取速度场的分布，且算法适用于具有分支河道的河水速度场求解.仿真结果表明：与现有的内河船舶模拟器中河流建模方法相比，该方法能较真实地反映河流速度分布，并能满足河流视景实时性的要求，提升河流视景的环境真实感.

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
