[Insight-users] Removing points from itk::PointSet

[Thomas Boettger]

Hi,

how do I remove points from my PoinSet or Mesh?

The following code:

   unsigned long testId = inputMesh->GetNumberOfPoints();
   InputPointType testPoint;
   testPoint.Fill(1.0);
   std::cout << "# of points: "  <<  inputMesh->GetNumberOfPoints() << 
std::endl;
   inputMesh->SetPoint(testId, testPoint);
   std::cout << "# of points: "  <<  inputMesh->GetNumberOfPoints() << 
std::endl;
   inputMesh->GetPoints()->DeleteIndex(testId);
   std::cout << "# of points: "  <<  inputMesh->GetNumberOfPoints() << 
std::endl;


produced the following output:

# of points: 128
# of points: 129
# of points: 129

...so the number of points did not decrease after the DeleteIndex() call.

How do I remove a point?

Thanks in advance,
Thomas
