Contour interpolator for to place points on polygonal surfaces.
vtkPolygonalSurfaceContourLineInterpolator interpolates and places contour points on polygonal surfaces. The class interpolates nodes by computing a graph geodesic laying on the polygonal data. By graph Geodesic, we mean that the line interpolating the two end points traverses along on the mesh edges so as to form the shortest path. A Dijkstra algorithm is used to compute the path. See vtkDijkstraGraphGeodesicPath.
The class is mean to be used in conjunction with vtkPolygonalSurfacePointPlacer. The reason for this weak coupling is a performance issue, both classes need to perform a cell pick, and coupling avoids multiple cell picks (cell picks are slow).

Subclasses that wish to interpolate a line segment must implement this.
For instance vtkBezierContourLineInterpolator adds nodes between idx1 and idx2, that allow the contour to adhere to a bezier curve.
Implements vtkPolyDataContourLineInterpolator.

The interpolator is given a chance to update the node.
vtkImageContourLineInterpolator updates the idx'th node in the contour, so it automatically sticks to edges in the vicinity as the user constructs the contour. Returns 0 if the node (world position) is unchanged.
Implements vtkPolyDataContourLineInterpolator.

Height offset at which points may be placed on the polygonal surface.
If you specify a non-zero value here, be sure to have computed vertex normals on your input polygonal data. (easily done with vtkPolyDataNormals).
