Hi Amy,

thanks again, what I found works in my case is to maintaim two
vtkPolyData's:

   m_connectivityFilter->SetExtractionModeToCellSeededRegions();
   m_connectivityFilter->SetInput(m_stripper->GetOutput());
   m_connectivityFilter->InitializeSeedList();
   m_connectivityFilter->AddSeed(0);
   m_connectivityFilter->Update();

   m_periosteumPolys->DeepCopy(m_connectivityFilter->GetOutput());

   m_connectivityFilter->InitializeSeedList();
   m_connectivityFilter->AddSeed(1);
   m_connectivityFilter->Update();

   m_endosteumPolys->DeepCopy(m_connectivityFilter->GetOutput());

and pass each to their respective mappers.

regards,
Dean
