// .NAME vtkPointInterpolator2D - interpolate point cloud attribute data
// onto x-y plane using various kernels
// .SECTION Description
// vtkPointInterpolator2D probes a point cloud Pc (the filter Source) with a
// set of points P (the filter Input), interpolating the data values from Pc
// onto P. Note however that the descriptive phrase "point cloud" is a
// misnomer: Pc can be represented by any vtkDataSet type, with the points of
// the dataset forming Pc. Similary, the output P can also be represented by
// any vtkDataSet type; and the topology/geometry structure of P is passed
// through to the output along with the newly interpolated arrays. However,
// this filter presumes that P lies on a plane z=0.0, thus z-coordinates
// are set accordingly during the interpolation process.
//
// The optional boolen flag InterpolateZ is provided for convenience. In
// effect it turns the source z coordinates into an additional array that is
// interpolated onto the output data. For example, if the source is a x-y-z
// LIDAR point cloud, then z can be interpolated onto the output dataset as a
// vertical elevation(z-coordinate).
//
// A key input to this filter is the specification of the interpolation
// kernel, and the parameters which control the associated interpolation
// process. Interpolation kernels include Voronoi, Gaussian, Shepard, and SPH
// (smoothed particle hydrodynamics), with additional kernels to be added in
// the future. See vtkPointInterpolator for more information.
// .SECTION Caveats
// This class has been threaded with vtkSMPTools. Using TBB or other
// non-sequential type (set in the CMake variable
// VTK_SMP_IMPLEMENTATION_TYPE) may improve performance significantly.
//
// For widely spaced points in Pc, or when p is located outside the bounding
// region of Pc, the interpolation may behave badly and the interpolation
// process will adapt as necessary to produce output. For example, if the N
// closest points within R are requested to interpolate p, if N=0 then the
// interpolation will switch to a different strategy (which can be controlled
// as in the NullPointsStrategy).
