The image generator function and author language software support for the CHARGE (Color Halftone Area Graphics Environment) Interactive Graphics System are described. Designed initially for use in computer-assisted instruction (CAI) systems, the CHARGE Interactive Graphics System can provide graphic displays for various applications including equipment design, troubleshooting, and mathematics. It can achieve color, gray level, and three-dimensional (3-D) perspectives. This report describes the system's procedure for representing a complex 3-D world, forming a colored perspective of that world, and then encoding the perspective in a format for tranmission to and display on a CHARGE terminal. Examples of CHARGE inputs and the system's resulting graphic displays together with flowcharts of the process are provided. (Author/DGC)
