[vtkusers] writing and reading with vtk

[Murat Aydın]

Hi,

my vtkunstructuredgrid contains only vtkPointData in which there is only a vtkBitArray and all values are 0 or 1.0. There is no other fields.

Kind Regards

  Oops, keyboard mistake... Let's go on:
  Replacing it by valid values fix my problem.

    Hi,
    I got such a problem, that comes from some -1.#IND or (Not-a-Number, or NaN) values in the fields. Replit by hand with a valid value

      Hi,

      I am writing vtkunsturucturedgrid to a file and then reading it.However, after reading i get nothing: number of cells , number of points all are zero.

      I attached my file.

      My code is :


      vtk.vtkXMLUnstructuredGridWriter w = new vtk.vtkXMLUnstructuredGridWriter(); 

      string ltempFile = System.IO.Path.GetTempFileName(); 

      w.SetFileName(ltempFile); 

      w.SetDataModeToBinary(); 

      w.SetInput(((vtk.vtkUnstructuredGrid)grid)); 

      w.Write(); 



      vtk.vtkXMLUnstructuredGridReader w2 = new vtk.vtkXMLUnstructuredGridReader(); 

      w2.SetFileName(ltempFile); 

      w2.Update(); 
      int num = w2.GetOutput().GetNumberOfPoints();

      Kind Regards
