Thanks, Shriram.<br><br>I do know how to read 'cone->GetOutput()-><layer id="google-toolbar-hilite-0" style="background-color: Yellow; color: black;">GetPoints</layer>()' 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><br>Toron<br><br><br><br><br><br><b><i>Shriram Iyer <shriram.uc@gmail.com></i></b> wrote:<blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"> Use cone->GetOutput()-><layer id="google-toolbar-hilite-0"
