Embodiment Construction

[0043] Many interactive graphics computer software applications process huge amounts of complex three-dimensional model data for presentation on one or more video displays. Such applications include, for example, computer-aided design (CAD) tools for designing three-dimensional objects, buildings and vehicles for manufacture, and geographic information system (GIS) tools for tracking public transportation systems or communication networks. Various embodiments of the invention improve these applications by filtering data for display according to easy-to-use and understandable techniques for defining and manipulating visual markers on graphical displays.

[0044] For example, how can a design engineer determine that two similar objects, both called "pipes," are actually completely different, and should not really be placed close to each other? One way is to store objects using ontological categories such that their "deep meaning" remains attached to them.

[0045] In general, u...

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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 61 / 185912, filed June 10, 2009, and US Provisional Application No. 61 / 267956, filed December 9, 2009. The contents of these applications are hereby incorporated by reference as if fully set forth herein. technical field [0003] Embodiments of the present invention relate to the graphical display of information on video displays, and more particularly, to improving the usability of interactive graphical modeling software applications whose visual display is supported by large amounts of data. Background technique [0004] People rely heavily on the meanings they attach to certain objects. A "pipe" can go from one side of the room to the other, but if it carries jet fuel, it's called a "fuel line". Another "pipe" could go from the ground to the ceiling of the same room, but since it is used to evacuate the heat from the steam boiler on the lower level,...
