Abstract

This article describes a method for rapidly drawing vectors on raster displays. Generating straight lines from a set of endpoints and storing the results in a memory map is a basic function of all advanced function displays and printers. When throughput requirements exceed reasonable software techniques, hardware is added to assist the vector generation. This article outlines the concepts of a unique table look- up technique which generates vectors faster than the conventional hardware and software approaches.
