[Insight-developers] Still bug in Mesh Filters ?

[J.Menssen at cukz.umcn.nl]

Hello

I'm working on a ITK project using the ITKSimplexMesh3DFilter and 
itkSimplexMeshAdaptTopologyFilter. 
I'm using the latest versions of itk (cvs archive) because I read in the
ITK bug-tracker 
database there were bugs in these filters (bug 0009554)
Maybe there are still bugs in these filters

Inspecting the code (itkSimplexMesh3DFilter::ComputeOutput), I read the
following

::ComputeOutput() 
{
  OutputMeshType * output = this->GetOutput();

  this->CopyInputMeshToOutputMeshPoints();
  this->CopyInputMeshToOutputMeshPointData();
  this->CopyInputMeshToOutputMeshCells();
  this->CopyInputMeshToOutputMeshCellData();

  output->SetGeometryData(this->m_Data);
  output->SetLastCellId( this->GetInput(0)->GetLastCellId() );
}

My Questions about these are
1)	Why are the Cell links not copied, there is a routine 
		CopyInputMeshtoOutpoutMeshCellLinks
2)	The pointer to the GeometryData is copied, not the content. Why
not the content, now 
		it's possible to delete the original data (when
reference count of the input data becomes 0, it's impossible to access
these data in a next stage of a program

Kind regards
