摘　　要：针对三维态势图中实时态势标绘的要求,首先建立标准的态势标绘箭头网格模型,然后利用网格形变使其能被实时地改变形状以满足不同场合的需求;为提高绘制效率,将网格的形变过程约束在二维环境中内进行,同时引入了LOD技术。最后,运用VC++6.0和OpenGL开发工具,实现了三维场景中的态势标绘箭头的实时形变仿真。实验证明该算法实现的三维态势标绘箭头满足实时性和逼真性的要求,可直接运用于各种三维态势标绘系统中。A new algorithm for the real-time constrained deformation of the arrow in three-dimensional common operational picture marking is presented. The standard mesh model of the plotting arrow is given. By suing the mesh deformation the arrow is deformed arbitrarily and by using the LOD technology the arrow can be used in different kinds of situation. By using the tools VC ＋ ＋ 6.0 and OpenGL the simulation of the arrow deformation in {hree-dimension- al scene is accomplished. The result of the simulation shows that the method can meet the real-time and reality requirements and it can be applied to many kinds of 3D plotting system.
