When a picture is drawn on an interactive graphics screen, the basic objects are organized into a hierarchy and a replica of the structure together with drawing instructions for the objects is stored. This enables subsequent selection of basic objects, sub-groups or whole groups of the hierarchy for manipulation by a cursor. In an interactive graphics application the picture being manipulated commonly has within it hierarchically organized objects. When interacting with the picture, using, for example, a graphics input device, it is necessary to allow the user to select within this hierarchy and operate on the data so selected. See the IBM Technical Disclosure Bulletin 28, 3305-3307 (January 1986). Basic objects in a picture can be organized into hierarchies.
