Hi all,
is it possible to import and export a vtkPolyData or can I use images only?
How can I do?
I have two vtkPolyData volumes, and I'd like to use itk filters like this :

vtk reader -> vtk filters -> itk filters -> vtk viewer
I've tried this :

VTK                            ->             ITK                    -> 
            VTK

ITKImageExporter4            VTKImageImporter4            
ITKImageImporter4        == first POLY

ITKImageExporter5            VTKImageImporter5 
                                                 == second POLY (no output)

but I don't know how to convert my vtkPolyData or how to typedef the 
VTKimporter to make it work :
    typedef unsigned short PixelType;
    typedef itk::Image<PixelType, Dimension> ImageType;
    typedef itk::VTKImageImport<ImageType> ImageImportType;
is ok but not with a polyData, and

    typedef itk::VTKImageImport<vtkPolyData*> ImageImportType;
 isn't ok

Thanks a lot

imho
