<div dir="ltr">I have not tried changing the representation in my application for vtkContourWidget. For vtkSeedWidget, I could do it using seed_representation->setHandleRepresentaion(). So you might have to insert a similar method into your subclass of (a derived class of) vtkContourRepresentation.<br>
<br>Initializing a wiget should take the following: yourContourRepresention->AddNodeAt....() and then widget->SetVisibleOn()<br><br>This will make the widget (with whatever number of points you add) appear by default. More points can always be added to it by the user.<br>

<br>Going by the default behavior of vtkContourWidget, the representation should not have any nodes (intermediate or not) until you right click (or close the contour). You can verify this by contour_representation->GetNumberOfNodes();<br>
<br>The intermediate nodes should be (though I have not) used to get the nodes within a certain range. <br><br>There are many ways to adding a node to a contour, for example: contour_representation->AddNodeOnContour(x, y);<br>
