I’d like to create a landmarking template with named, unplaced points. I can unset the position status of a point I have placed, but would like to add points to the node with uninitialized positions. It looks like I could do this if I could access vtkMRMLMarkupsNode::AddNControlPoints from python. Would this be the best approach, or is there a way to call vtkMRMLMarkupsNode::AddControlPoint with an uninitialized control point?
Alternatively, would it be preferable to set the coordinates of unplaced points to something like [0,0,0]?
@lassoan I’m interested in your thoughts on the correct approach.
