If you want a classification like that then make that many different Collections . When you run IsItemPresent() on any collection if the actor is not available in the corresponding collection it will return a 0 . Or any other efficient method . It is more of a programming challenge I guess .<br>
<br>Yes you can make changes to the polydata . That should not be a problem . <br><br>Regards<br>Darshan<br><br><br><div class="gmail_quote">On Tue, Mar 9, 2010 at 3:33 AM, Rakesh Patil <span dir="ltr"><<a href="mailto:rakeshthp@in.com">rakeshthp@in.com</a>></span> wrote:<br>

have several types of data to be displayed, like, scattered xyz data,
triangular mesh data, poly lines, polyvertex, polygons, circles etc.. So
if i create a collection of actors, later on after picking them, how
will I classify which actor contains what data..??<br><br>Secondly,
using<br><br>Actor->GetMapper()->Getinput() - and you have your
PolyData<br><br>can i make any changes to the data in the polydata..??
For example, in the polyline data, i want to change the value of a
particular vertex, and after changing this value, the change should
immediately be reflected on the vtk window.. Can this be done..??<br><br>Thanks<br><br>Regards<br>Rakesh

So you can use a vtkActorCollection class and add these actors to the collection using AddProp() function<br><br>Now when the CellPicker picks any PolyLine, it basically can identify the Prop selected using the Getprop() function<br>
Theis you can reference in the collection using the IsItemPresent() function in the vtkActorCollection class<br><br>Actor->GetMapper()->Getinput() - and you have your PolyData<br><br>Hope that helps<br><br>Regards<br>

<br>Now i select this data using vtkCellPicker. After selecting, I need to draw a circle around this polyline. Is this possible..??<br>
<br>Let me remind you, there are several polylines, and only one polyline is to be selected... Now the problem is after picking this polyline,<br>how will i come to know which polyline is selected and how to get the data of that polyline..?? Secondly, this polyline defines a boundary. <br>
A solid boundary, and soft boundary.. The circle is to be drawn only if the polyline is a solid boundary. So this checking how can be done.?<br><br>I have attached a sample image file how i want the output to be..<br><br>
