* @class vtkRotationFilter
* @brief Duplicates a data set by rotation about an axis
*
* The vtkRotationFilter duplicates a data set by rotation about one of the
* 3 axis of the dataset's reference.
* Since it converts data sets into unstructured grids, it is not efficient
* for structured data sets.
*
* @par Thanks:
* Theophane Foggia of The Swiss National Supercomputing Centre (CSCS)
* for creating and contributing this filter
