Hi All,<br><br>I used the following codes to build a simple cone.<br>---------------------------------------------------------------------------------------<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();<br> coneMapper->SetInput( cone->GetOutput() );<br>--------------------------------------------------------------------------------------<br>Does any one can help me to know how to get the position (x,y,z) of each vertex and the rendering index? Thanks in advance!<br><br>Toron<br><p> __________________________________________________<br>Do You Yahoo!?<br>Tired of spam? Yahoo! Mail has the best spam protection around <br>http://mail.yahoo.com
