interpolate from the weighted closest point
vtkProbabilisticVoronoiKernel is an interpolation kernel that interpolates from the closest weighted point from a neighborhood of points. The weights refer to the probabilistic weighting that can be provided to the ComputeWeights() method.
Note that the local neighborhood is taken from the kernel footprint specified in the superclass vtkGeneralizedKernel.

Given a point x, a list of basis points pIds, and a probability weighting function prob, compute interpolation weights associated with these basis points.
Note that basis points list pIds, the probability weighting prob, and the weights array are provided by the caller of the method, and may be dynamically resized as necessary. The method returns the number of weights (pIds may be resized in some cases). Typically this method is called after ComputeBasis(), although advanced users can invoke ComputeWeights() and provide the interpolation basis points pIds directly. The probably weighting prob are numbers 0<=prob<=1 which are multiplied against the interpolation weights before normalization. They are estimates of local confidence of weights. The prob may be nullptr in which all probabilities are considered =1.

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.
