/**
* @class vtkInterpolateDataSetAttributes
* @brief interpolate scalars, vectors, etc. and other dataset attributes
*
* vtkInterpolateDataSetAttributes is a filter that interpolates data set
* attribute values between input data sets. The input to the filter
* must be datasets of the same type, same number of cells, and same
* number of points. The output of the filter is a data set of the same
* type as the input dataset and whose attribute values have been
* interpolated at the parametric value specified.
*
* The filter is used by specifying two or more input data sets (total of N),
* and a parametric value t (0 <= t <= N-1). The output will contain
* interpolated data set attributes common to all input data sets. (For
* example, if one input has scalars and vectors, and another has just
* scalars, then only scalars will be interpolated and output.)
