Abstract

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 ontologically 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.

11. A method according to claim 1, further comprising:

displaying the selected data on the video display.

12. A method according to claim 11, further comprising:

displaying on the video display data in the dataset that is not selected, wherein displaying the selected data includes displaying the selected data according to a display mode that visually distinguishes it from the non-selected data.

13. A method according to claim 12, wherein each visual indicium has a user-selectable color, and according to the display mode, data associated with the attribute of each visual indicium are displayed in the color of that visual indicium.

14. An apparatus for displaying representations of three-dimensional objects on a graphics display device, the apparatus comprising:

a filtering processor, coupled to the database and the storage device, configured to receive a selection of at least one of the plurality of data filters, and filter the data in the dataset according to the meanings associated with the selected data filters to produce a display dataset; and

a display processor, coupled to the graphics display device and the filtering processor, the display processor being configured to receive the display dataset from the filtering processor, and to cause the graphics display device to display the display dataset.

15. An apparatus according to claim 14, wherein the storage device is further configured to store a plurality of ontological filters, each ontological filter being associated with one or more of the data stored in the database, and wherein the filtering processor is further configured to filter the data in the dataset according to the one or more data associated with a selected ontological filter to produce the display dataset.
