Abstract
Abstract Methods and apparatus are disclosed for the rapid creation of wire frame representations of 3-dimensional objects using generic wire frames which are prototypical of a class of objects and which are modifiable to correspond to a specific instance of the class. A set of generic wire frames are bundled as a tool kit with software for editing wire frames. A method of morphing from a source 3-dimensional stereo rendered wire frame to a target rendered wire frame is also disclosed and the apparent camera viewpoint can change during morphing.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
122 words
Apparatus for rapidly creating wire frame representations of three dimensional objects comprising: a. computer having an input/output device, a display, a memory and mass storage: b. generic wire frames stored on said mass storage; and c. software, for controlling said computer, permitting a generic wire frame to be oriented so it aligns with a first view of a three dimensional object, modifying, if needed, the location of at least one vertex of the generic wire frame to overlay a feature point in said first view to create a modified wire frame, orienting said modified wire frame so it aligns with a second view of said object, and modifying the location of said vertex to overlay said feature point in said second view.
Claim 2
Dependent Claim
122 words
Apparatus for rapidly creating wire frame representations of three dimensional objects comprising: a. computer having an input/output device, a display, a memory and mass storage: b. generic wire frames stored on said mass storage; and c. software, for controlling said computer, permitting a generic wire frame to be oriented so it aligns with a first view of a three dimensional object, modifying, if needed, the location of at least one vertex of the generic wire frame to overlay a feature point in said first view to create a modified wire frame, orienting said modified wire frame so it aligns with a second view of said object, and modifying the location of said vertex to overlay said feature point in said second view.
Claim 3
Dependent Claim
28 words
Apparatus of claim 1 in which the generic wire frames comprise a tool kit having a plurality of wire frames generic to a respective plurality of different objects.
Claim 4
Dependent Claim
39 words
Apparatus of claim 1 in which the software for editing includes: a. means for selecting a vertex of a generic wire frame and for dragging the position of said vertex from one location on the display to another location.
Claim 5
Dependent Claim
24 words
Apparatus of claim 1 in which the software for editing includes: a. means for adding a vertex between two vertices of a wire frame.
Claim 6
Dependent Claim
24 words
Apparatus of claim 1 in which the software for editing includes: a. means for deleting a vertex between two vertices of a wire frame.
Claim 7
Dependent Claim
20 words
Apparatus of claim 5 in which database entries of predecessor and successor vertices are altered when said vertex is deleted.
Claim 8
Independent Claim
106 words
A method for rapidly creating a custom wire frame of a three dimensional object, comprising: a. orienting so it aligns with a first view of an object; b. modifying, if needed, at least one vertex of said view of said generic wire frame by dragging said vertex from an original position in the generic wire frame and dropping said vertex on a feature point of said view to create a modified wire frame; c. orienting said modified wire frame so it aliens with a second view of said object; and d. modifying the location of said vertex to overlap said feature point in said second view.
Claim 9
Independent Claim
106 words
A method for rapidly creating a custom wire frame of a three dimensional object, comprising: a. orienting so it aligns with a first view of an object; b. modifying, if needed, at least one vertex of said view of said generic wire frame by dragging said vertex from an original position in the generic wire frame and dropping said vertex on a feature point of said view to create a modified wire frame; c. orienting said modified wire frame so it aliens with a second view of said object; and d. modifying the location of said vertex to overlap said feature point in said second view.
Claim 10
Dependent Claim
20 words
The method of claim 7 further comprising rendering said custom wire frame using transformed bit mapped portions of said image.
