Abstract
Abstract The virtual reality imaging system takes a multidimensional space that contains real world objects and phenomena, be they static or dynamic in nature, and enables a user to define a point and/or a path through this multidimensional space. The apparatus then displays the view to the user that would be seen from the point and/or path through the multidimensional space. This view is filtered through user definable characteristics that refine the real world phenomena and objects to a perspective that is of interest to the user. This filtered view presents the user with a virtual view of the reality contained within this multidimensional space, which virtual reality presents data to the user of only objects, views and phenomena that are of particular interest to the user.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
145 words
Apparatus for presenting a user with a virtual image of phenomena located in a predefined multidimensional space, comprising: means for generating data indicative of at least one phenomena extant in a multidimensional space, which multidimensional space has predefined extent in a plurality of dimensions; means for converting said generated data to a compact data representation of said at least one phenomena; means for storing data defining a plurality of characteristics of said phenomena that are to be displayed to a user; means for extracting data, that satisfies said plurality of characteristics defined by said stored data, from said compact data representation; and means, responsive to said extracted data, for producing an image representative of a three dimensional view of at least a portion of said multidimensional space to display said phenomena, substantially temporally concurrent with the generation of said data used to produce said image.
Claim 2
Dependent Claim
145 words
Apparatus for presenting a user with a virtual image of phenomena located in a predefined multidimensional space, comprising: means for generating data indicative of at least one phenomena extant in a multidimensional space, which multidimensional space has predefined extent in a plurality of dimensions; means for converting said generated data to a compact data representation of said at least one phenomena; means for storing data defining a plurality of characteristics of said phenomena that are to be displayed to a user; means for extracting data, that satisfies said plurality of characteristics defined by said stored data, from said compact data representation; and means, responsive to said extracted data, for producing an image representative of a three dimensional view of at least a portion of said multidimensional space to display said phenomena, substantially temporally concurrent with the generation of said data used to produce said image.
Claim 3
Dependent Claim
32 words
The apparatus of claim 1 wherein said converting means generates data for said compact data representation indicative of a presence and locus of said at least one phenomena in said multidimensional space.
Claim 4
Dependent Claim
32 words
The apparatus of claim 2 wherein said converting means generates data indicative of an extent of said phenomena in said multidimensional space, said compact data representation defining exterior surfaces of said phenomena.
Claim 5
Dependent Claim
56 words
The apparatus of claim 3 further comprising: means for storing data representative of at least one texture map, which texture map is indicative of features of a surface of said phenomena; and wherein said image producing means accesses data in said storing means corresponding to a selected one of said texture maps to produce said image.
Claim 6
Dependent Claim
46 words
The apparatus of claim 4 wherein said image producing means retrieves said data indicative of exterior surfaces of said phenomena concurrent with accessing data in said storing means corresponding to said selected texture map; means for altering said surface to incorporate features of said texture map.
Claim 7
Dependent Claim
34 words
The apparatus of claim 5 wherein said image generation means converts said compact data representation data indicative of said exterior surfaces to a pixel by pixel image of said exterior surface of said phenomena.
Claim 8
Dependent Claim
34 words
The apparatus of claim 3 wherein said image generation means retrieves locus information of said phenomena from said compact data representation to define position of exterior surfaces of said phenomena in said multidimensional space.
Claim 9
Dependent Claim
41 words
The apparatus of claim 7 wherein said image producing means arbitrates among a plurality of phenomena to identify segments of exterior surfaces of ones of said phenomena to be represented in a foreground of a field of view from a user.
Claim 10
Dependent Claim
27 words
The apparatus of claim 8 wherein said image producing means combines said identified segments of exterior surfaces to present an inter-object spatial relationship view to said user.
