Abstract:OpenGL is soft interface of image display hardware (display card). The hardware driver is called by OpenGL API to interacte with image display hardware directly. In the real-time display application of radar image, the chartlet of image point was drawn with glDrawPixels function. The current raster position was defined with glRasterPos, and chartlet form of image point was controlled with glPixelStore. The factor of proportionality for amplification and reduction in horizontal and vertical was set up with glPixelZoom. The result of simulation test proved that the OpenGL satisfies the need of radar image display.
Keywords:Radar image  Real-time display  OpenGL  Chartlet of image point  Raster Operating
