摘　　要：针对战场态势三维场景下标号的生成方法进行了研究,提出以现有的二维标号算法为基础,通过对该算法输出的二维绘制基础图元进行分解和坐标变换,获得标号的三维绘制基础图元,然后在OpenSceneGraph(OSG)中构造出所有的三维绘制基础图元,组合成三维标号;整个构造过程中不需要对点标号及线面标号做区别对待,所有标号都采取统一的矢量生成方法。实验结果表明,使用该方法生成的三维标号能继承原有二维标号的处理算法,达到很好的三维显示效果。The article researches on how to create military symbols in the 3D scene of battlefield situations. It brings on a new method that depends on the existed 2D military symbols＇ algorithm whose results of 2D basic primitives can be analyzed and con verted to 3D basic primitives, after that, OpenSceneGraph （OSG） is used to construct these 3D basic primitives. In the process of this method, all of 3D military symbols are created in the same way. At the end, the experimental result shows that the 3D military symbols not only inherit 2D military symbols＇ algorithm but also display nice effect in the virtualization system.
