摘要
提出了一种将视在光线法(Light Of Sight,LOS)与OpenGL软件接口相结合的方法。该方法利用OpenGL软件接口的深度测试与遮挡查询功能,确定了复杂外形目标在某探测方向上的有效发射面元及其辐射在介质中的传输路径。然后采用LOS法获得了大气层内目标在探测方向上的辐射特性。仿真结果表明,本文方法行之有效,且计算效率高。
An algorithm combining Light of Sight （LOS） with the OpenGL software interface is proposed, The method uses the depth measuring and occlusion query functions of the OpenGL software interface to determine the effective emission surface in the detection direction and the transfer path of its radiation in mediums. Then, it uses LOS to obtain the radiation characteristics of the target in atmosphere in the detection direction. The simulation result shows that this algorithm is effective and has high computation efficiency.
