I think that it would be a great feature if vtkTubeFilter had an option to
pass polygons directly to the output.  Unfortunately, right now there isn't
any way to do this without changing the vtkTubeFilter source code.

Instead, you can use vtkAppendPolyData to append the original data onto the
output you get from vtkTubeFilter.  Of course, this means that your tubes
will have the lines put back inside of them, but that should be harmless.
