[vtkusers] How to draw dash dot lines and circle?

[hp.shen]

Hi, all
 
I have to questions.
1)    How to draw dash/dash-dot lines in VTK
2)    With vtkQuadric I  drawed a circle , and it's a solid line circle.
While what I want is a dash line circle. So, is it possible to draw a
dash line circle in VTK?
       Or is there other ways to draw a circle?
 
Many thanks in advance.
 
       peace
