Abstract: A graphics data management system that includes control tables for quickly accessing information about the display structures to be drawn. A series of control tables and hashed indexes to graphics descriptors allow structure storage editing commands to quickly and effectively edit structure details. A hierarchical graphics data language results in a hierarchical network of structure elements and associated graphic primitive commands. The editor provides a method to preserve the hierarchy while efficiently accomplishing editing tasks. Hashing tables to the structure I.D., pick I.D., label I.D. and a chained list of execute structures are maintained to rapidly access and control those elements. Structure storage is maintained in local memory with certain portions shared with the graphics control processor.
