[vtkusers] vtk add automatic points in delaunay 3D??

[David Imboden]

Hello,

 

When I write an output with VTK, he add me some points (end of file)! Why?

How to correct this?

 

Thanks

 

Vtk code :

 

p->InsertNextPoint(1,0,1) ;

      p->InsertNextPoint(2,0,2) ;

      p->InsertNextPoint(3,0,1) ;

      p->InsertNextPoint(4,0,2) ;

      p->InsertNextPoint(5,0,1) ;

      p->InsertNextPoint(6,0,2) ;

      p->InsertNextPoint(7,0,1) ;

      p->InsertNextPoint(8,0,2) ;

      p->InsertNextPoint(9,0,1) ;

      p->InsertNextPoint(10,0,2) ;

 

      p->InsertNextPoint(1,1,1) ;

      p->InsertNextPoint(2,1,2) ;

      p->InsertNextPoint(3,1,1) ;

      p->InsertNextPoint(4,1,2) ;

      p->InsertNextPoint(5,1,1) ;

      p->InsertNextPoint(6,1,2) ;

      p->InsertNextPoint(7,1,1) ;

      p->InsertNextPoint(8,1,2) ;

      p->InsertNextPoint(9,1,1) ;

      p->InsertNextPoint(10,1,2) ;

 

      pd->SetPoints(p) ;

      delaunay3d->SetInput(pd) ;

      delaunay3d->BoundingTriangulationOn() ;

      delaunay3d->Update() ;

      uGridW->SetInputConnection(delaunay3d->GetOutputPort());

      uGridW->SetFileName("test.txt") ;

      uGridW->Write() ;
