【摘要】针对常规的纹理映射方法制作三维地球时存在的颜色数据量大、对硬件图形显示要求较高及立体感不强的弊端,运用Matlab提供的专业的地球高程数据颜色映射表,提出了一种基于地球高程数据的三维地球模型制作方法,并通过坐标变化将弹道位置参数转化为地心大地直角坐标,从而在三维彩色地球的基础上,绘制出了三维弹道曲线,仿真试验表明,所制作的三维弹道模型立体感及真实感较强,为弹道仿真提供了一种有效手段。%As the traditional texture mapping method of drawing Earth has the shortcoming of great amount of color data, high requirement of hardware graphical display and the weak stereo perception, this paper proposed a method of modeling three-di?mensional Earth based on DEM data and the colormap provided by Matlab. It also draws the three-dimensional trajectory by transforming coordinates based on the Earth model above. The simulation results show that the model proposed by this paper has good three-dimensional effect and this paper provides an effective method of trajectory simulation.
