Developments in Equipment and Techniques: Microcomputer Graphics Environments

Abstract

Publisher Summary Computer graphics, whereby an image is constructed under computer control and displayed on a cathode ray tube (CRT), provides a familiar and useful way to display computer output. Computer graphics are particularly useful for the presentation of complex data and in that context are universally used for the preparation and presentation of geographical and other information that is naturally graphical or pictorial in nature. Computer graphics are as old as computers themselves. This chapter focuses on microcomputer graphics, particularly on those associated with the IBM PC and compatibles. It presents a review of the principles behind microcomputer graphics in general and a description of current trends in personal computer and workstation graphics hardware and software. The chapter also presents a historical review that introduces the various categories of computer graphics systems and defines their capabilities in terms of graphics controllers and processors, personal computer standards, add-in graphics and video cards, and graphics workstations and systems.
