Abstract:

A multilevel graphical data structure for an 18-bit digital computer is described. Graphical entities defined by the data structure may be linked together by a ring structure, logically tied coordinates, or other independent parameters. The structure is ideally suited for use with a large, delayed-access, mass-storage device, as the displayed picture representing the graphical entities can be generated independently of their logical linking.
