[vtkusers] Re: How to write multiple surfaces into a single STL file?

[Goodwin Lawlor]

You can:
1. Use vtkAppendPolyData to append all the outputs from multiple
vtkContourFilter's into one PolyData
2. Just use one instance of vtkContourFilter (and one vtkActor etc) in the
first place, extracting all the contours by setting multiple contour values
in the one filter
