[vtk-developers] splitting vtkSurfaceReconstructionFilter into 2 classes

[Arnaud GELAS]

  Hi all,

For a very long time the class vtkSurfaceReconstructionFilter has been 
executing two different processes into the same class (as described in 
the Hoppe et al's paper):

   1. Estimate normal given a point set
   2. Reconstruct an implicit function from this point set with the
      associated normals.

However, there are many new surface reconstruction methods out there 
that out perform this method, but the normal estimation technique 
remains as one of the most effective technique.

Most of the user/developer who use surface reconstruction technique 
ended reimplementing the normal estimation technique (e.g. as David 
Doria did in one his VTK journal paper), or some other split the 
vtkSurfaceReconstructionFilter into 2 classes (as we do in our group for 
the development of gofigure2).

    * Would it be possible to extract the normal estimation from this class?

You can have a look at
http://github.com/arnaudgelas/gofigure2/blob/master/trunk/Code/ExternalCode/PoissonReconstruction/vtkNormalEstimationFilter.h
http://github.com/arnaudgelas/gofigure2/blob/master/trunk/Code/ExternalCode/PoissonReconstruction/vtkNormalEstimationFilter.cxx

    * Would it be possible to rename the vtkSurfaceReconstructionFilter?
      This method is not the only method for surface reconstruction and
      is nowadays more popular for its drawbacks/failures than some more
      recent methods (such as Poisson reconstruction technique see Doria
      and Gelas VTK Journal on the topic...).


Thanks in advance for considering this change,
Best Regards,
Arnaud
