CHARGE Interactive Graphics System Terminal: Theory of Operation.

摘要

This report documents the CHARGE Interactive Graphics System terminal. Designed initially for use in instructional systems, the CHARGE terminal can provide considerable and versatile graphics display for many applications (including equipment design, trouble-shooting, etc.). While being cost-competitive, the CHARGE terminal system can achieve color, gray level, 3-D perspectives, and rapid updating. Perspective views can be simply, rapidly, and economically generated from a (3-D) xyz-coordinate, dynamically changing, 'real world' description. In this report, the terminal's image encoding and hardware architecture are described from a theoretical and detailed logic point of view.
