A user-oriented computer graphics system

Abstract

A user-oriented Computer Graphics System (CGS) is described, which primarily has been designed to aid the application programmer, and not just the sophisticated computer graphics user. The system has been designed to provide a very simple interaction capability, where the interaction is based on a variety of input devices and a simple input/output graphics command language. The result of this system has been an increase in programming efficiency, reduction in span time from creations of design to actual implementation. Typical application developments have included such system as flowcharting systems, Computer Aided Architectural Space Planning, Animation, Vehicle-Pedestrian Interactions, Computer-aided designs, and the simulation of the NASA Space Shuttle.
