  // .NAME vtkPointDataToCellData - map point data to cell data
  // .SECTION Description
  // vtkPointDataToCellData is a filter that transforms point data (i.e., data
  // specified per point) into cell data (i.e., data specified per cell).
  // The method of transformation is based on averaging the data
  // values of all points defining a particular cell. Optionally, the input point
  // data can be passed through to the output as well.
  
  // .SECTION Caveats
  // This filter is an abstract filter, that is, the output is an abstract type
  // (i.e., vtkDataSet). Use the convenience methods (e.g.,
  // GetPolyDataOutput(), GetStructuredPointsOutput(), etc.) to get the type
  // of output you want.
  
  // .SECTION See Also
  // vtkPointData vtkCellData vtkCellDataToPointData
