/**
* @class vtkMergeVectorComponents
* @brief merge components of many single-component arrays into one vector
*
* vtkMergeVectorComponents is a filter that merges three single-component arrays
* into one vector. This is accomplished by creating one output vector with
* 3 components. The type of the output vector is vtkDoubleArray. The user
* needs to define the names of the single-component arrays and the attribute-type
* of the arrays, i.e. point-data or cell-data.
*
* @warning
* This class has been threaded with vtkSMPTools. Using TBB or other
* non-sequential type (set in the CMake variable
* VTK_SMP_IMPLEMENTATION_TYPE) may improve performance significantly.
