摘　　要：提出了基于OpenGL ES核心库的机载图形生成算法,可简洁高效地进行图形操作直至在终端屏幕上绘制出二维图形景观。研究了宽度直线、三角形的边、屏幕反走样和矢量文本显示等关键技术。宽度直线反走样实例表明算法有较好效果。电子飞行仪表绘制的实验表明图形生成算法准确高效,可以移植到专用的军工硬件平台,应用于航空图形显示等领域。Graphics generation algorithms based on OpenGL ES Core are proposed for aircraft platform. Some key techniques are discussed, such as specified-width line, triangle＇s edge, full-scene anti-aliasing, and vector text display. The example of anti-aliasing for specified-width lines shows the algorithm achieves good result. The example of the electronic flight instrument shows that the algorithm can be used in aircraft graphics display system on special military hardware platform.
