[vtkusers] converting vtkGraph to boostGraph to use with OpenGraphFixedTracking from D. Doria

[Dr. Roman Grothausmann]

Dear mailing list members,


How can I use a vtkGraph as a boostGraph which is needed for 
OpenGraphFixedTracking from D. Doria 
(http://www.midasjournal.org/browse/publication/828)?
I looked at vtkBoostBreadthFirstSearch.cxx and included vtkBoostGraphAdapter.h 
(see below) and copied it to the project dir (seems this header-file is not 
installed with VTK, why?) but I still get an error:

error: invalid user-defined conversion from ‘vtkGraph*’ to ‘const Graph& {aka 
const boost::adjacency_list<boost::vecS, boost::vecS, boost::undirectedS, 
boost::no_property, EdgeVisibility>&}’ [-fpermissive]

What am I missing?

Any help or hints are very much appreciated
Roman
