[vtkusers] What is intermediate nodes in vtkContourWidgets?

[Rakesh Patil]

Dear Prathamesh,I was trying to insert the intermediate nodes.. But i failed to do so.. Well, i went through the documentation of vtkHandleRepresentation..It is an abstract class.. So do i need to derive my own class and implement some functions..?? How do i use this class with vtkContourRepresentation..? Well, i create a contour using the mouse clicks.. In this case, how can i initialize a contour with two nodes,,?? As the positions of the nodeswill be available only when user clicks on the graphics window..Thanks Original message From:"Prathamesh Kulkarni"< prathameshmkulkarni at gmail.com >Date: 22 Jul 10 20:21:38Subject: Re: Re: What is intermediate nodes in vtkContourWidgets?To: Rakesh Patil I have not had the representations changed for my application. But this may be achieved by using the vtkHandleRepresentation with your vtkContourRepresentation. To handle the intermediate nodes, you can initialize a contour with two nodes (with some representation) and allow the user to
  add more nodes (with some other representation).

I mean except for the first and the last click all other nodes must be intermediate nodes.Any idea, how to do this??Thanks Original message  From:"Prathamesh Kulkarni"< prathameshmkulkarni at gmail.com >Date: 21 Jul 10 21:45:46Subject: Re: What is intermediate nodes in vtkContourWidgets? To: rakeshthp at in.comHello Rakesh, 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 contourrepresentation>GetNumberOfNodes();The intermediate nodes should be (though I have not) used to get the nodes within a certain ran
 ge. There are many ways to adding a node to a contour, for example: contourrepresentation>AddNodeOnContour(x, y);PrathameshMessage: 30 Date: Wed, 21 Jul 2010 20:18:51 +0530 From: "Rakesh Patil"Subject: [vtkusers] What is intermediate nodes in vtkContourWidgets? To: "vtkusers"MessageID:ContentType: text/plain; charset="utf8"Hello,From the documentation of vtkOrientedGlyphContourRepresentation,i came across intermediate nodes..?? What are these and how to addthem?? When i get the total number of intermediate nodes, i get theoutput as zero..what is this intermediate nodes and how to add them anddisplay?thanks.Dear vtkusers !
