// .NAME vtkRotationFilter - Duplicates a data set by rotation about an axis
// .SECTION Description
// 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.
//
// .SECTION Thanks
// Theophane Foggia of The Swiss National Supercomputing Centre (CSCS)
// for creating and contributing this filter
