// .NAME vtkExtractVectorComponents - extract components of vector as separate scalars
// .SECTION Description
// vtkExtractVectorComponents is a filter that extracts vector components as
// separate scalars. This is accomplished by creating three different outputs.
// Each output is the same as the input, except that the scalar values will be
// one of the three components of the vector. These can be found in the
// VxComponent, VyComponent, and VzComponent.
// Alternatively, if the ExtractToFieldData flag is set, the filter will
// put all the components in the field data. The first component will be
// the scalar and the others will be non-attribute arrays.
// .SECTION Caveats
// This filter is unusual in that it creates multiple outputs.
// If you use the GetOutput() method, you will be retrieving the x vector
// component.

// Get the output dataset representing velocity y-component. If output is
// NULL then input hasn't been set, which is necessary for abstract
// objects. (Note: this method returns the same information as the
// GetOutput() method with an index of 1.)
// Note that if ExtractToFieldData is true, this output will be empty.

// Description:
// Get the output dataset representing velocity z-component. If output is
