摘要: 采用动态分页调度算法结合LOD技术实现了海量三维地形数据的加载与显示,研究三维军标绘制技术,提出了一种基于可视范围动态计算投影区域的方法,解决了三维线、面标号纹理模糊不清问题。采用MVC设计模式搭建二三维联动战场可视化系统框架,实现了二三维在视域范围、态势标号、地理信息查询之间的联动。

Abstract: With paged arithmetic and LOD technology, large numbers of 3D terrain data can be loaded and displayed. Studying the method of protracting 3D symbol, the paper proposes a valid solution to increase texture resolution of 3D symbol based on calculating projection region dynamically. With MVC architecture, it designs and implements a battlefield visualization system based on interactive 2D&3D GIS.

Key words: interactive 2D&3D, battlefield situation, visualization, 3D military symbol
