[vtkusers] Save a plane in a vtp file?

[David Doria]

Excellent, thank you Amy. I also found
vtkAppendPolyData.h<http://www.vtk.org/doc/nightly/html/vtkAppendPolyData_8h-source.html>
to attach them together.  For anyone else interested:

void TwoCubes(const string &OutputFilename)
{
    vtkSmartPointer<vtkCubeSource> Cube1 =
vtkSmartPointer<vtkCubeSource>::New();
    Cube1->SetCenter(0.0, 0.0, 0.0);
    Cube1->SetXLength(.5);
    Cube1->SetYLength(.5);
    Cube1->SetZLength(.5);

    vtkSmartPointer<vtkCubeSource> Cube2 =
vtkSmartPointer<vtkCubeSource>::New();
    Cube2->SetCenter(5.0, 0.0, 0.0);
    Cube2->SetXLength(.5);
    Cube2->SetYLength(.5);
    Cube2->SetZLength(.5);

    vtkSmartPointer<vtkPolyData> polydata1 = Cube1->GetOutput();
    vtkSmartPointer<vtkPolyData> polydata2 = Cube2->GetOutput();

    vtkSmartPointer<vtkAppendPolyData> CombinedData =
vtkSmartPointer<vtkAppendPolyData>::New();;
    CombinedData->AddInput(polydata1);
    CombinedData->AddInput(polydata2);

    //write the file
    vtkSmartPointer<vtkXMLPolyDataWriter> writer =
vtkSmartPointer<vtkXMLPolyDataWriter>::New();
    writer->SetInput(CombinedData->GetOutput());

    writer->SetFileName(OutputFilename.c_str());
    writer->Write();

}

Thanks,

David
