摘要
在航海操纵模拟器的视景可视化建模中,冰区场景需要的海冰面积非常大,大量海冰模型在视景场中动态创建模型和底层数据管理需要科学高效的方法,否则会耗费大量时间和空间资源,影响整个程序的实时性以及可视化效果。将四叉树空间索引算法应用于航海模拟器视景系统中海冰模型的动态创建和管理,可以较大程度上减少时间和空间资源的消耗,提升整个视景系统的流畅性,优化海冰场景的可视化效果,为航海模拟器海冰视景场的实时仿真提供了创建和管理基础,也为冰区模拟器系统后续的船冰交互过程提供了科学高效的数据基础。
In the process of modeling for scene visualization in marine simulator, ice region scene needs plenty of sea ice. Because of the numerous sea ice models, it may cause huge waste of time and space then make the whole simulation system in a poor real-time visualization situation, if there is no scientific or effective method. Applying quad-tree spatial index algorithm to sea ice dynamic modeling and management in ice region scene system of marine simulator, it could reduce consumption of time and space resources, improve the whole system fluency, and optimize the visualization of sea ice scene. And it also provides a foundation which could simulate the ice region scene real-time and the ship-ice interaction effectively.
