Fw: [vtkusers] Closing 3d surfaces...

> dear michal and dear all,

> We are curently working on a similar problem.
> We have found a quite easy solution for one hole, but it doesn't work when
> you have multiple holes.
> Please find along the corresponding code, implemented as a VTK class
> (VtkCloseMesh).
> vtkCloseMesh.* are the main files
> vtkCloseMeshTCL_INIT.cxx is for TCL wrapping
> and the .dsp files are for compiling with MSVC++
>
> Here is the method under "heavy" :-) investigation right now which should
> lead to the multiple holes' closing:
>
> * find edge through VtkFeatureEdge class,
> * separate holes (method is still to find , we are thinking about using
the
> vtkConnectivityFilter somehow, but it would mean we are first able to join
> all the points corresponding to one specific edge)
> * apply the allready existing method (implemented in our vtkCloseMesh) to
> close each hole one by one.
>
> If someone allready implemented a working solution to this problem, or if
> someone go any idea about another vtk class that could be used in a smart
> way here, please contact either Bertrand Delhay
> (bdelhay at ge-serveur.insa-lyon.fr) who is responsible for this point in the
> team, or myself.
