[vtkusers] Feret Diameter

[Cory Quammen]

Eduardo,

I am not aware of a filter that provides the Feret diameter.

Do you have the plane that determines the orientation you want for the
Feret diameter in implicit form (a, b, c, d)? If so, then you should just
need to iterate over each point (x, y, z) in the polydata, compute ax * by
* cz - d, keep track of the minimum and maximum of those computed values,
subtract the minimum from the maximum, and get the desired diameter.

HTH,
Cory
