An on-line two-dimensional computation system
Thomas G. Williams · 1972
The role of graphics in interactive man-computer systems is to extend the capability of the computer for communication in a visual mode so that men can communicate with the computer directly in the figurative notations and graphics conventions that they have developed for communication among themselves. A large number of computer-graphics systems have been developed, most of them directed toward drawing lines, curves, or shapes, as in schematic drawing, solid and half-tone drawing, and computer animation. Considerable work has also been done in computer output of drawings and graphs.
