AN IMPROVED PROCEDURE FOR GENERATION OF HALF TONE COMPUTER GRAPHICS PRESENTATIONS,

Abstract

The function of the LINESCAN algorithm is to process the projected image of the three-space structure on the viewing plane and deliver the 'key squares' of the scanned picture to the output routine which will construct the final photographic half-tone image. The 'key squares' are the locations of the hardware scanning beam where the intensity function will change. These beam intensity change points are located on the viewing plane within the 'window' near one of two places: (1) intersections between projected edges and the scanline and (2) intersection of the scanline and the projection of the intersection between two polygons ('implicitly defined line').
