[vtkusers] TubeFilter on PolyData with constant Radius

[Karim Khayrat]

Hello,
  I have a polyData structure with points and lines. I apply the TubeFilter
on it, and I would like to have the tube radii vary with scalar. However
when I use* *SetVaryRadiusToVaryRadiusByAbsoluteScalar(), I get a tapered
tube, since the scalar values at the points are used. I am trying to
visualize an unstructured network.
Any Tips ?
Thanks
