// .NAME vtkPointSet - abstract class for specifying dataset behavior
// .SECTION Description
// vtkPointSet is an abstract class that specifies the interface for
// datasets that explicitly use "point" arrays to represent geometry.
// For example, vtkPolyData and vtkUnstructuredGrid require point arrays
// to specify point position, while vtkStructuredPoints generates point
// positions implicitly.
// .SECTION See Also
// vtkPolyData vtkStructuredGrid vtkUnstructuredGrid
