摘　　要：提出了一种三维箭标绘制的新方法，在完成控制点输入和生成，并进行地形匹配的基础上，通过利用OpenGL的Bezier曲面绘制函数直接生成箭标上、下曲面和各个侧面，最终实现具有一定厚度的三维箭标的绘制。相较于传统的三角剖分法，该方法计算量小，程序简洁，可有效实现三维箭标的实时标绘。The paper puts forward a new method to plotting 3D arrowhead. Based on completing the input and generation of control points and match of the terrain, it realizes to plot 3 D arrowhead with a given thickness by using OpenGL＇ s Bezier curve function to produce each surface of the arrowhead directly. Compared to traditional triangle analysis method, this method has a small amount of calculation and compact program, could realize real -time plotting of 3D arrowhead effectively.
