Toron,<br><br>I'm not quite sure what you are trying to do here. If you just want to the location of <br>each vertex in the cone, you can use following code.<span class="q"><br><br>vtkPoints* points = vtkPoints::New();
<br>points = cone->GetOutput()->GetPoints();
<br><br></span>for (vtkIdType i = 0; i < points->GetNumberOfPoints(); i++)<br>{<br> double Pt[3];<br> points->GetPoint(i, Pt);<br> // Pt will now have the x, y, z coordinates of vertex i.<br> ...<br>}<br><br>

Thanks, Shriram.<br><br>I do know how to read 'cone->GetOutput()->GetPoints()' you suggested. So I tired to add the below codes. <br>-------------------------------------------------------------------------<br>
vtkPoints *points = vtkPoints::New();<br> points = cone->GetOutput()->GetPoints(); <br><br> vtkCellArray *indexes = vtkCellArray::New();<br> indexes = cone->GetOutput()->GetPoints(); <br>------------------------------------------------------------------------
<br>They did work. Could you correct them or let me know any example like this?<br><span class="sg"><br>Toron</span><div><span class="e" id="q_115c9a5d74afd442_2"><br><br><br><br><br><br><b><i>Shriram Iyer <<a href="mailto:shriram.uc@gmail.com" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">

<br> vtkConeSource *cone = vtkConeSource::New();<br> cone->SetHeight( 3.0 );<br> cone->SetRadius( 1.0 );<br> cone->SetResolution( 6 );<br> <br> vtkPolyDataMapper *coneMapper = vtkPolyDataMapper::New();
