Well,then what should i do inorder to move the nodes or edit the positions of the nodes..? I cant do it through the actor directly right,,??thanks Original message From:"Jothy"< jothybasu at gmail.com >Date: 22 Jul 10 21:54:33Subject: Re: Re: Re: [vtkusers] combine vtkContourWidgets question.To: Rakesh Patil I don't think you need to delete the contourWidgets, as far as I understand it will allow you to only trace over the image to display them over the image after traacing you need to create an actor to display it permanently to them.

For this i have to manipulate the list of vtkContourWidgets objects..Thus i thought better to first find out is there any other possibility to get this done..

 : Re: [vtkusers] combine vtkContourWidgets question.To: Rakesh PatilGet the output of the two contours, it will be in vtkPolyData type and use append filter and then display it. You can use addObservers to make it interactive.JothyOn Thu, Jul 22, 2010 at 5:03 PM, Rakesh Patilwrote: Well,as far as my knowledge is concerned, vtkAppendPolyDataFilter is used to merge two or more polydata.. but i am having two widgets..( of vtkContourWidget type) Can it be used in this case..??Thanks Original message From:"Jothy"< jothybasu at gmail.com >Date: 22 Jul 10 21:17:54Subject: Re: [vtkusers] combine vtkContourWidgets question.To: Rakesh PatilWon't the vtkAppendPolyDataFilter do that ?
