forgot ->update(), sorry

I thought it was called by GetOutput()
when required.

  This byte of code does not produce any triangle.
  any idea about what I did wrong?

  tmpPolyData is a vtkPolyData;
  points coordinates range from 
  500000 to 1000000 in x and z,
   -5000 to 5000 in y

  //----------------------------------------------------------------------------------------
  cout <<"# points : " <<tmpPolyData->GetNumberOfPoints() <<endl; //49587
  cout <<"# polys : " <<tmpPolyData->GetNumberOfPolys() <<endl;   // 0

  vtkDelaunay2D *delaunay = vtkDelaunay2D::New();
  delaunay->SetInput(tmpPolyData);
  delaunay->SetTolerance(0.001);

  cout <<"# points : " <<delaunay->GetOutput()->GetNumberOfPoints() <<endl;  // 0, expected 49587
  cout <<"# polys : " <<delaunay->GetOutput()->GetNumberOfPolys() <<endl;    // 0, expected around 100 000

  //------------------------------------------------------------------------------------------
