Abstract
Abstract In a graphical object manipulation system, a system for modifying shapes ludes representing a reference shape in terms of particles making up the shape, providing a Coulomb warp between the particles of the reference shape and those of a target shape, modifying the Coulomb warp and using the modified warp to generate a modified target shape from the reference shape by displacing particles in the reference shape to modified positions in the target shape based on modified displacements. The system permits shape averaging or providing a shape with a distinctive style.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
152 words
In a graphical manipulation system, a system for combing shapes comprising: a reference shape, first and second target shapes to be combined; means for representing said shapes in terms of bit maps made up of particles such that each bit map describes a different shape; means for providing a warp between said reference shape and said first and second target shapes in terms of the displacement of a particle associated with a point in said reference shape to a corresponding point in each of said target shapes, thereby to represent each target shape with a warp from said reference shape; means for modifying said displacements to combine said target shapes so as to provide a combined bit map; and, means for rendering a shape based on said combined bit map, thereby to provide a new shape which is the result of combining said warps and thus the combining of said target shapes.
Claim 2
Dependent Claim

In a graphical manipulation system, a system for combing shapes comprising: a reference shape, first and second target shapes to be combined; means for representing said shapes in terms of bit maps made up of particles such that each bit map describes a different shape; means for providing a warp between said reference shape and said first and second target shapes in terms of the displacement of a particle associated with a point in said reference shape to a corresponding point in each of said target shapes, thereby to represent each target shape with a warp from said reference shape; means for modifying said displacements to combine said target shapes so as to provide a combined bit map; and, means for rendering a shape based on said combined bit map, thereby to provide a new shape which is the result of combining said warps and thus the combining of said target shapes.
Claim 3
Dependent Claim
51 words
The system of claim 1 wherein said warp is a Coulomb warp the use of said Coulomb warp taking a uniform density of particles on said reference shape and providing a uniform density of particles in said target shape, thus to eliminate unpleasing holes and density gradients in said target shape.
Claim 4
Dependent Claim
13 words
The system of claim 1 wherein said warp is a nearest neighbor warp.
Claim 5
Dependent Claim
35 words
The system of claim 1 wherein said means for modifying said displacements includes means for averaging the displacements from a point on said reference shape to corresponding points on said first and second target shapes.
Claim 6
Dependent Claim
124 words
In a graphical manipulation system, a system for combing shapes comprising; a reference shape, first and second target shapes to be combined; means for representing said shapes in terms of particles; means for providing a warp between said reference shape and said first and second target shapes in terms of the displacement of a particle associated with a point in said reference shape to a corresponding point in each of said target shapes thereby to represent each target shape as a warp from said reference shape; and, means for modifying said displacements to combine said shapes and for rendering the result thereof thereby to provide a new shape which is the result of combing said warps and thus the combining of said target shapes.
Claim 7
Dependent Claim
124 words
In a graphical manipulation system, a system for combing shapes comprising; a reference shape, first and second target shapes to be combined; means for representing said shapes in terms of particles; means for providing a warp between said reference shape and said first and second target shapes in terms of the displacement of a particle associated with a point in said reference shape to a corresponding point in each of said target shapes thereby to represent each target shape as a warp from said reference shape; and, means for modifying said displacements to combine said shapes and for rendering the result thereof thereby to provide a new shape which is the result of combing said warps and thus the combining of said target shapes.
Claim 8
Dependent Claim
51 words
The system of claim 5 wherein said warp is a Coulomb warp the use of said Coulomb warp taking a uniform density of particles on said reference shape and providing a uniform density of particles for said target shape, thus to eliminate unpleasing holes and density gradients in said target shapes.
Claim 9
Dependent Claim
13 words
The system of claim 5 wherein said warp is a nearest neighbor warp.
Claim 10
Dependent Claim
35 words
The system of claim 5 wherein said means for modifying said displacements includes means for averaging the displacements from a point on said reference shape to corresponding points on said first and second target shapes.
