ONTOLOGICAL FILTERING USING SPATIAL BOUNDARY OF 3D OBJECTS

摘要

Methods and apparatus are provided that improve graphical software applications, by filtering the data for display according to techniques for defining and manipulating visual indicia. Data may be filtered according to multiple filters that are combined in a number of ways to form the set of data for display. Data may be filtered onto logically and geometrically according to their relationships with other data. Visual indicia that represent filters may be drag-and-dropped between input areas to facilitate ease of use. Data selected according to a filter may be displayed at the same time as non-selected data by applying visually distinctive characteristics to the selected data. A virtual environment may be shown simultaneously on several different video displays at a single workstation.
