Abstract: 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 3D military 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.
