一种基于三角形递归切分的三维军标绘制方法

Rendering Method for 3D Military Symbols Based on Triangle Recursive Segmentation

针对三维战场仿真环境中三维军标的实时绘制问题,利用Bezier曲线的任意可分性,提出了一种新的基于三角形递归切分的三维动态军标通用绘制方法。首先,通过设置军标控制点自动生成二维军标图形;然后,对二维军标模型进行三角形递归切分并动态控制递归算法调用次数;最后,对每个特征点赋予高程值,从而生成并显示三维动态军标图形。实验结果表明,该算法在不同地形条件下应用于多种基本的三维军标中都能保持良好的匹配速度和匹配效果。该方法在保证通用性前提下可以满足军标标绘系统的实时性需求。

In order to solve the problem of real time rendering of the 3D military symbol in battlefield simulation environment,using the arbitrary separability of Bezier curve,we proposed a new universal rendering method for 3Dmilitary symbol based on triangle recursive segmentation.Firstly,2D military symbols are generated by setting the control points.Secondly,the segmentation graphics are achieved by triangle recursive segmentation.In addition,the recursive calls are dynamiclly controlled.Lastly,each feature point is given a elevation value,as a result,the 3D military symbols are generated.The experimental results denote that the algorithm can maintain good matching speed and matching effect when it is used in a variety of basic 3D military symbols under different terrain conditions.This method can meet the needs of real-time military plotting system on the premise that it is highly general.
