Abstract
Abstract Supplemental data, as textured data, for use with geometric data to produce a display image is expanded by relating between display space and model space. A texture map storing supplemental data is enhanced by first applying new texture data as color, to an image in two dimensional display space. The locations for the data in the dimensional model space are determined and transformed into texture map space to receive the applied new texture data. Texture data is placed in the texture map by scan conversion of texels and blending.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
104 words
A method for updating texture maps on a computer system corresponding to a textured, three-dimensional object, the method comprising the steps of: providing a first set of texture naps corresponding to said textures, three-dimensional object; selecting a first orientation of said textured, three-dimensional object; displaying in a first perspective view in a computer display said oriented, three-dimensional object; applying supplemental data to said first perspective view of said oriented, three-dimensional object on said computer display; merging said first set of corresponding texture maps for said three-dimensional object with said supplemental data to provide an second set of corresponding texture maps for said three-dimensional object.
Claim 2
Independent Claim
104 words
A method for updating texture maps on a computer system corresponding to a textured, three-dimensional object, the method comprising the steps of: providing a first set of texture naps corresponding to said textures, three-dimensional object; selecting a first orientation of said textured, three-dimensional object; displaying in a first perspective view in a computer display said oriented, three-dimensional object; applying supplemental data to said first perspective view of said oriented, three-dimensional object on said computer display; merging said first set of corresponding texture maps for said three-dimensional object with said supplemental data to provide an second set of corresponding texture maps for said three-dimensional object.
Claim 3
Dependent Claim
44 words
The method of claim 1 further including the steps of: selecting a second orientation of said textured, three-dimensional object; displaying in a second perspective view on a computer display said second oriented, three-dimensional object including said supplemental data responsive to said second perspective view.
Claim 4
Dependent Claim
94 words
The method of claim 1 further including the steps of: providing three-dimensional model data corresponding to said textured, three-dimensional object, said three-dimensional model data having continuous three dimensional; wherein said displaying in a second perspective view step includes, transforming said three dimensional model data to the space of said second set of texture maps to provide map location data, testing said map location data for image visibility to identify visible map locations in said second perspective view and blending said visible new data at said identified visible map locations of said second perspective view.
Claim 5
Dependent Claim
19 words
The method according to claim 3 wherein said three dimensional model data in the form of a polygonal mesh.
Claim 6
Dependent Claim
21 words
The method according to claim 3 wherein said transforming step includes transforming three dimensional polygons to two dimensional picture elements (pixels).
Claim 7
Dependent Claim
18 words
The method according to claim 1 wherein said applying step includes applying said supplemental data with a brush.
Claim 8
Dependent Claim
13 words
The method according to claim 1 wherein said supplemental data is an image.
Claim 9
Dependent Claim
14 words
The method according to claim 1 wherein said supplemental data is a bump map.
Claim 10
Dependent Claim
106 words
A computer graphic system for updating texture maps on a computer system corresponding to a textured, three-dimensional object and having a first set of texture maps, the method comprising: means for selecting a first orientation of said textured, three-dimensional object; means for displaying in a first perspective view on a computer display said oriented, three-dimensional object; means for applying supplemental data to said first perspective view of said oriented, three-dimensional object on said computer display; means for merging said first set of corresponding texture maps for said three-dimensional object with said supplemental data to provide an second set of corresponding texture maps for said three-dimensional object.
Claim 11
Dependent Claim
106 words
A computer graphic system for updating texture maps on a computer system corresponding to a textured, three-dimensional object and having a first set of texture maps, the method comprising: means for selecting a first orientation of said textured, three-dimensional object; means for displaying in a first perspective view on a computer display said oriented, three-dimensional object; means for applying supplemental data to said first perspective view of said oriented, three-dimensional object on said computer display; means for merging said first set of corresponding texture maps for said three-dimensional object with said supplemental data to provide an second set of corresponding texture maps for said three-dimensional object.
Claim 12
Dependent Claim
45 words
The system of claim 9 further comprising: means for selecting a second orientation of said textured, three-dimensional object; means for displaying in a second perspective view on a computer display said second oriented, three-dimensional object including said supplemental data responsive to said second perspective view.
Claim 13
Dependent Claim
98 words
The system of claim 9 further comprising: means for providing three-dimensional model data corresponding to said textured, three-dimensional object, said three-dimensional model data having continuous three dimensions; wherein said means for display in a second perspective view includes, means for transforming said thee dimensional model data to the space of said second set of texture maps to provide map location data, and means for testing said map location data for image visibility to identify visible map locations in said second perspective view and blending said visible new data at said identified visible map locations of said perspective view.
