ABSTRACT:
The invention relates to a graphic display device. The main object of the invention is a screen display device using a combination of directed-beam scanning for drawings of patterns and frame-scanning display for surface coloring. The device of the invention comprises a microprocessor which makes real-time calculations, for each line displayed, of the starting and finishing abscissae of the various colors to be used. Real-time computing by the microprocessor makes it possible to use video memories instead of the habitually used page memories and to replace a very bulky and expensive graphic processor with a fast microporocessor. The invention can be applied chiefly to the display of three-dimensional perspective views on color screens.
