[vtkusers] How to build a polydata with polygons from a given vtkMutableUndirectedGraph

[Sebastian Rahner]

Dear all,

i still have not found a solution for my problem.

I created a polydata from a vtkMutableUndirectedGraph via 
vtkGraphToPolydata. Each vertex has a position in world coordinates, so 
that a mesh-like structure is defined by the graph. The edges are passed 
to the polydata correctly. But i also want to build the polygons which 
are defined by the vertices and connecting edges.

I tried to use the vtkFillHolesFilter as well as 
vtkSurfaceReconstructionFilter which both did not work for my problem.

I would appreciate any advice.

Thanks
