[vtk-developers] Proposed CenterOfMass function for vtkPoints

[Will Schroeder]

My concern with the term centroid is to differentiate the centroid of
the points from the centroid of the dataset, which can be different.
Since the user generally asks a dataset for its points, it would be
easy to make the mistake of assuming that the centroid of a dataset
matches the centroid of the points. Maybe this is just a documentation
issue, but it needs to be clear.
