Abstract

A simple modification of Horn's circle drawing procedure yields a disk generator for a class of graphic devices capable of drawing rectangular areas. Another variation produces a disk a scan-line at a time allowing it to be drawn at the refresh rate of the display. The calculations involve only additions and binary shifts.
