[vtkusers] Getting verts and lines from polydata source

[Charl P. Botha]

I really prefer not top-quoting, but your Outlook has embedded your
message in such a way that gmail can't inline your message with little
> thingies.  Oh well.

To answer your question: pass the output of the vtkCubeSource through
a vtkExtractEdges.

I am using a vtkCubeSource to create a cube but I would like to get
just the verts and lines from it to make a wireframe basically.  So
far I have tried to create a vtkPolyData and use the GetVerts() from
the GetOutput() from the cube source and SetVerts() on the
vtkPolyData.  I do this for the lines as well.  This didn't work for
me so I tried a GetNumberOfVerts() and GetNumberOfLines() on the
GetOutput() from the cube source and both resulted in zero.
  
Can someone see what I'm doing wrong or how I can accomplish what I'm
trying to do.  If any of this is confusing I can include a code chunk.
  
Thanks, 
Alex
