// .NAME vtkProbePolyhedron - probe/interpolate data values in the interior,
// exterior or of the surface of a closed, manifold polyhedron
// .SECTION Description
// vtkProbePolyhedron is a filter that computes point attributes (e.g.,
// scalars, vectors, etc.) at specified point positions. The filter has two
// inputs: the Input and Source. The Source geometric structure is passed
// through the filter. The point attributes are computed at the Input point
// positions by interpolating into the source data. In this filter, the
// Source is always a closed, non-self-intersecting, polyhedral mesh. For
// example, we can compute data values on a plane (plane specified as Input)
// from a triangle mesh (e.g., output of marching cubes).
//
// This filter can be used to resample data from a mesh onto a different
// dataset type. For example, a polyhedral mesh (vtkPolyData) can be probed
// with a volume (three-dimensional vtkImageData), and then volume rendering
// techniques can be used to visualize the results. Another example: a line
// or curve can be used to probe a mesh to produce x-y plots along that line or
// curve.
// .SECTION Caveats
// Note that cell data is not interpolated from the source. If you need cell data,
// you can always use vtkPointDataToCellData and/or vtkCellDataToPointData in
// various combinations.
//
// Note that the filter interpolates from a mesh to points interior, exterior
// or on the surface of the mesh. This process is necessarily an
// approximation. Currently the approach of Mean Value Coordinates is used,
// but this filter may be extended in the future to use other methods.
