航海模拟器中冰区视景的研究

冰区航行在实际航海活动中越来越受到人们的关注。实用性强且具有逼真仿真度的冰区航行模拟器的应用,对船员培训与航运评估等航海科学应用领域都有着很重要的实际意义。将冰区航行模拟器为整体设想框架,以冰区视景仿真为基本研究内容,在理论与具体实现上对冰区中海冰的模型建立与其可视化方法进行了初步的探索和研究。参考了Koch分形曲线的思想,分析和建立了基本的海冰模型,实现了浮冰破碎以及随波漂动效果,并借鉴了Cohen-Sutherland等相关计算机图形学算法,实现了船舶冰区航行时海冰与船间的快速碰撞检测。

Research on Visualization of Ice Navigation in Marine Simulator

Ice navigation,which is paid close attention in the actual navigation lately,becomes more and more significant activity increasingly.So an effective ice navigation simulator will make great sense for seaman training and shipping assessment.Referring to the Koch Curve from the fractal algorithm,an analysis and a simple model of the sea ice were made fundamentally,and the visual of broken ice was actualized which floated in the ice area channel.Based on the Cohen-Sutherland Algorithm,collision detection between ship and sea ice in the visual view of the ice navigation were actualized.
