### Code

WriteVTP.java

    import vtk.vtkNativeLibrary;
    import vtk.vtkPoints;
    import vtk.vtkPolyData;
    import vtk.vtkXMLPolyDataWriter;

    public class WriteVTP {

      // Loading Native Libraries.
      // Now it works in eclipse without any issues.
      static {
        if (!vtkNativeLibrary.LoadAllNativeLibraries()) {
          for (vtkNativeLibrary lib : vtkNativeLibrary.values()) {
            if (!lib.IsLoaded()) {
              System.out.println(lib.GetLibraryName() + " not loaded");
            }
          }
        }
        vtkNativeLibrary.DisableOutputWindow(null);
      }

      public static void main(String[] args) {
        //parse command line arguments
        if (args.length != 1) {
          System.err.println("Usage: java -classpath ... WriteVTP Filename(.vtp) e.g WriteVTP.vtp");
          return;
        }

        String filename = args[0];

        //Create 10 points.
        vtkPoints points = new vtkPoints();

        for (int i = 0; i < 10; ++i) {
          points.InsertNextPoint(i, i, i);
        }

        //Create a polydata object and add the points to it.
        vtkPolyData polydata = new vtkPolyData();
        polydata.SetPoints(points);

        //Write the file
        vtkXMLPolyDataWriter writer = new vtkXMLPolyDataWriter();
        writer.SetFileName(filename);
        writer.SetInputData(polydata);

        //Optional - set the mode. The default is binary.
        //writer.SetDataModeToBinary();
        //writer.SetDataModeToAscii();

        writer.Write();
      }
