[ITK-users] Error in itk::BinaryMask3DMeshSource when using Mesh with arbitrary CellDataType

[Arnaud Gelas]

Hi Sepide,

You are right, there is no need for this filter to call SetCellData, it 
would be great if you could submit a patch to fix it!

Have a look at

Best,
Arnaud

Looking at itkBinaryMask3DMeshSource.hxx source code, I noticed that this filter is initializing Cell data to 0.0, meaning it assumes the CellDataType to always be castable to double (which my std::pair<> type was obviously not>.
