Title:
GENERATOR FOR ARTIFICIAL HORIZON BETWEEN SKY SHADING AND GROUND SHADING
Document Type and Number:
Japanese Patent JPS58225313
Kind Code:
A
Abstract:
An artificial horizon display generator determines either sky shading or ground shading in real time as each pixel of a raster display is generated. Transition line parameters are specified by a host processor (30), whereupon a display generator (48) computes whether the raster line currently being generated will intersect the horizon boundary line, and if so, at what X-Y transition point. Pixels generated prior to the transition point are of the initial shading; pixels generated subsequent to the transition point are of the opposite shading.
