摘要: 基于过程法建立河流流体运动模型,并利用有限差分的方法解算,从而获取视景系统中河流运动的速度场;利用Multigen Creator建模软件创建视景系统中的场景模型,并运用细节层 次技术提升视景系统仿真的效率;最后采用相关的可视化技术,实现了内河船舶操纵模拟器中视景系统的实时仿真。仿真结果表明:建立的河流流体速度场模型可较真实地体现河流流动性, 视景系统可增强内河船舶操纵模拟器的环境真实感,并且视景系统的效率远超过仿真实时性要求。

Abstract: Based on the procedural method, a fluid motion model of river was established and solved by the finite difference method.Thus, the velocity field of river motion in visual system was obtained.The scene model of visual system was built by modeling software Multigen Creator,and LOD technology was applied to improve the simulation efficiency of visual system.The relative visualization technologies were utilized to realize the real time simulation of visual system in inland river ship handling simulator. The simulation results show that the established fluid velocity field model of river can reflect the fluidity of river more truly, and the visual system can improve the environment reality in inland river ship handling simulator, moreover, the efficiency of visual system is much higher than the requirement of real time simulation.

Key words: traffic and transportation engineering, inland river, ship handling simulator, visual simulation system, procedural method, real time
