Greetings!  
I need to export Segmentation as ONE gtlf file. I noticed I can use [SlicerOpenAnatomy](https://github.com/PerkLab/SlicerOpenAnatomy/), but using the python code——

```auto
exporter = vtk.vtkGLTFExporter()
exporter.SetRenderWindow(slicer.app.layoutManager().threeDWidget(0).threeDView().renderWindow())
exporter.SetFileName("c:/tmp/newfolder/mymodel.gltf")
exporter.Write()

```

——will export the entire scene and create a gltf file and several bin files.  
like this:

Could anyone help me find the code that can export the Segmentation to ONE gtlf file?
