As you stated, you already have your 3D image (data) in .raw file format. <br>
You could save it in another format (one single file or multiple files) if needed:<br><br></div><div>vtkNew<vtkSome_Kind_Of_Image_Writer> writer;<br></div><div>writer->SetInput( my_Raw_Image_Data_Reader->GetOutput() );<br>
