雷达三维场景显示中的地球大气圈渲染方法

Method of earth atmosphere's rendering in 3D scene display of radar

针对雷达三维场景显示系统需要用尽可能少的资源实现地球大气圈渲染的需求,提出了一种基于公告板技术实现模拟地球大气圈的渲染方法.该方法使用渐变色圆环模拟地球大气圈,并使用公告板调整渐变色圆环的位置,可以简单、高效地实现模拟大气圈的绘制.仿真结果表明,该方法渲染效率高,真实感强,可用于雷达三维场景显示.

Considering that the radar＇s 3D scene display system is on demand of implementing the earth atmosphere＇s rendering with resources as little as possible, this paper comes up with a method of implementing and simulating the earth atmosphere＇s rendering based on the billboard technique. In this scheme, the gradient annulus are employed for simulating the earth atmosphere, and the billboard is used for adjusting the position of the gradient annulus, which may implement and simulating the drawing of atmosphere simply and efficiently.Simulation results show that this method is of higher rendering efficiency and stronger third dimension, which can be used as the 3D scene display of radar.
