[vtkusers] Closed Loop/Spline - Area

[Jerome Velut]

Hi Jean-Hugues,

The vtkMassProperties filter effectively computes features from a 
triangle mesh. If your closed splines are lying on a single plane, you 
have better chance to write your own filter that will compute the area 
of a polygon, as you hopefully have an ordered set of points that 
defines this polygon.

Best regards,
Jerome
