Abstract
A polygonal image-drawing processor has a device for providing a direction of a linear vector on each of sides constituting a polygon based on information about two end points X and Y and side information of the polygon; a device for dividing each of the polygonal sides into two groups of right-handed and left-handed sides in accordance with the provided direction of the linear vector; a device for calculating an X address of each of dots between the two end points by a digital differential analysis with respect to a direction of a Y-coordinate; a device for controlling the operation of an image memory in a writing region thereof corresponding to each of the divided groups to write X and Y addresses at left-handed and right-handed intersection points of the polygon to the image memory; and an image-drawing processing device for performing a coloring operation between the respective right-handed and left-handed sides based on the X and Y addresses written to the image memory so as to draw an image. Another polygonal image-drawing processor is also shown.
