Here a small example that i use:


      Field<Vector3D> dhField = (Field) this.getDisplayedData();

        DrillholeMesh dhMesh = dhField.getMesh();
        double[] curvilinearAbscissae = dhMesh.getCurvilinear();
        int nbFieldValues = dhField.getValues().length;
        Drillhole dh = dhField.getDrillhole();
          @SuppressWarnings("unchecked")
          FieldDh<Vector3D> field = dhField;
          if (field == null)
            return false;
          vtkPoints points = new vtkPoints();
          points.SetDataTypeToDouble();
          double[] pc = new double[3];
          double[] ps = new double[3];
          Vector3D[] values = field.getValues();
          if (values != null) {
            double sizeMaxField = aValue;
            vtkArrowSource arrow = new vtkArrowSource();
            arrow.SetTipRadius(0.1);
            arrow.SetTipLength(1.);
            arrow.SetShaftResolution(6);
            arrow.SetShaftRadius(0.03);*/
            vtkDoubleArray vector3DArray = new vtkDoubleArray();
            vector3DArray.SetNumberOfComponents(3);
            vector3DArray.SetName("Vector");
            for (int i = 0; i < nbFieldValues; i++) {
              Vector3D fieldValue = values[i];
              if (fieldValue != null && fieldValue != field.getNoValue()) {
                Point3D p =
dh.getSurvey().getPoint(curvilinearAbscissae[i]);
                ps[0] = p.x;
                ps[1] = p.y;
                ps[2] = p.z;
                points.InsertNextPoint(ps);
                vector3DArray.InsertNextTuple3(fieldValue.getX(),
fieldValue.getY(), fieldValue.getZ());
              }
            }
            vtkPolyData polyData = new vtkPolyData();
            polyData.SetPoints(points);
            polyData.GetPointData().SetVectors(vector3DArray);


            vector3DGlyph = new vtkGlyph3D();
            vector3DGlyph.SetVectorModeToUseVector();
            vector3DGlyph.OrientOn();
            vector3DGlyph.SetScaleFactor(sizeMaxField/2.);
            vector3DGlyph.SetScaleModeToDataScalingOff();
            vector3DGlyph.SetColorModeToColorByScalar();

            vector3DGlyph.SetSourceConnection(arrow.GetOutputPort());
            vector3DGlyph.SetInputData(polyData);
            vector3DGlyph.Update();


Hope it help you.
