Detailed Description

a Voronoi interpolation kernel

vtkVoronoiKernel is an interpolation kernel that simply returns the closest point to a point to be interpolated. A single weight is returned with value=1.0.

Warning: In degenerate cases (where a point x is equidistance from more than one point) the kernel basis arbitrarily chooses one of the equidistant points.

vtkIdType vtkVoronoiKernel::ComputeBasis	(	double	x[3],
		vtkIdList *	pIds,
		vtkIdType	ptId = `0`
	)

overridevirtual

Given a point x (and optional associated ptId), determine the points around x which form an interpolation basis.

The user must provide the vtkIdList pIds, which will be dynamically resized as necessary. The method returns the number of points in the basis. Typically this method is called before ComputeWeights().

Implements vtkInterpolationKernel.

vtkIdType vtkVoronoiKernel::ComputeWeights	(	double	x[3],
		vtkIdList *	pIds,
		vtkDoubleArray *	weights
	)

overridevirtual

Given a point x, and a list of basis points pIds, compute interpolation weights associated with these basis points.

Note that both the nearby basis points list pIds and the weights array are provided by the caller of the method, and may be dynamically resized as necessary. Typically this method is called after ComputeBasis(), although advanced users can invoke ComputeWeights() and provide the interpolation basis points pIds directly.

Implements vtkInterpolationKernel.
