[vtkusers] vtkConnectivityFilter and connected components

[David Cole]

Did you try running vtkConnectivityFilter again (on the output of the 
first run of vtkConnectivityFilter...), but this time using 
SetExtractionModeToSpecifiedRegions and AddSpecifiedRegion to choose 
one region at a time?

 From the documentation, that looks like it should yield what you're 
asking for.

Hi guys.

I've a polydata composed by many disconnected components. By using
vtkConnectivityFilter I'm able to identify each of these components and
assign a specific Id for them (see enclosed picture). Now I'd like to
isolate every of these components for a further process, for instance to
calculate the volume of them. How can I do it?

Many thanks.

Matheus.
