/**
* @class vtkUncertaintyTubeFilter
* @brief generate uncertainty tubes along a polyline
*
* vtkUncertaintyTubeFilter is a filter that generates ellipsoidal (in cross
* section) tubes that follows a polyline. The input is a vtkPolyData with
* polylines that have associated vector point data. The vector data represents
* the uncertainty of the polyline in the x-y-z directions.
*
* @warning
* The vector uncertainty values define an axis-aligned ellipsoid at each
* polyline point. The uncertainty tubes can be envisioned as the
* interpolation of these ellipsoids between the points defining the
* polyline (or rather, the interpolation of the cross section of the
* ellipsoids alog the polyline).
