Method for dynamically maintaining multiple structural interpretations in graphics system

摘要

An object oriented graphic input and display system for graphical abstract objects, responsive to user selected manipulation functions, having a data structure (70; Fig. 3A) including input means, display means and function selection means, the input means being user manipulable for entering graphical objects onto the display and for selecting functions on the function selection means for manipulating the graphical objects, a lattice data structure (100) responsive to data signals from the data structure representing objects entered on the display for decomposing the abstract objects into elemental objects, means (108,110) for organizing elemental objects into groups of elemental objects, and means for re-organizing the groups of elemental objects into a further group of elemental objects, the graphical data structure and function selection means coordinating the reorganization in accordance with user selection of functions to be performed on all or on portions of the objects.
