Hello,
I am assiging a label value for each connected component in the image that I am using to generate the mesh. In the picture each rib has a different label in the original image.
I am just trying to check if the corrected label is assigned to each cell of the output mesh, I will need that information later.
I tryed to do something similar to your code but it does not print.
Thank you
vtkSmartPointer<vtkPolyData> outputPolyData = discrete_smooth_mesher->GetOutput();
vtkCellData* pointData = outputPolyData->GetCellData();
vtkDataArray* scalarArray = pointData->GetArray(0);
if (scalarArray) {
std::unordered_set<int> uniqueValues;
for (vtkIdType i = 0; i < scalarArray->GetNumberOfTuples(); ++i) {
int scalarValue = static_cast<int>(scalarArray->GetTuple1(i));
uniqueValues.insert(scalarValue);}
