摘　　要：为了有效地在空间场景中表现各种类型传感器的侦察探测能力,提出了一种通用的可视化方法。根据传感器类型定义其探测范围表面;由于描述传感器探测范围的曲面具有公共顶点,因此将其离散为可以利用射线进行描述的三角形;解决了这种可视化方式涉及到的关键技术,包括离散射线与地球球面交点和切点的计算、不同显示类型下绘制策略的设计、基于一维纹理的脉冲效果实现等。按组件对象模型规范设计实现了传感器组件,并成功应用到空间场景可视化控件中。To representing detection ability of sensor in space scene,a general visualization algorithm is put forward.A surface of detection ability based on sensor＇s type is defined.The surface is tessellated to triangles,which are described by radial because of the common vertex on the surface.The key technologies within the method are solved,which includes calculation of intersection point and tangent point between radial from sensor and spherical surface of earth,design of render strategy for different display type,implementation of pulse effect based on one dimension texture,etc.The component implemented is applied successfully in visualization of space scene.
