// .NAME vtkCenterOfMass - Find the center of mass of a set of points.
// .SECTION Description
// vtkCenterOfMass finds the "center of mass" of a vtkPointSet (vtkPolyData
// or vtkUnstructuredGrid). Optionally, the user can specify to use the scalars
// as weights in the computation. If this option, UseScalarsAsWeights, is off,
// each point contributes equally in the calculation.
//
// You must ensure Update() has been called before GetCenter will produce a valid
// value.

// a vtkCenterOfMass object. The scalars can be set to NULL
// if all points are to be weighted equally. If scalars are
// used, it is the caller's responsibility to ensure that the
// number of scalars matches the number of points, and that
// the sum of the scalars is a positive value.
