Abstract

The analog graphics display is one of the most fascinating devices that computer technology has produced. The fluidity and complexity of motion possible with line-drawing displays is quite captivating and has initiated many interesting and fruitful software endeavors. Unlike their analog counterparts, the majority of raster-scan display systems have been capable of producing only text or static imagery. Dynamic graphics on raster displays has yet to be explored thoroughly in either the hardware or software area. This paper describes a digital video display system architecture with dynamic graphics capabilities. The hardware design and implementation derives from the author's thesis work at the University of Illinois.
