I am writing a python module for 3D Slicer. I have a surface (vtkPolyData). I want to display this in the 3D view. I know how to do this with a volume, i.e. using sitkUtils.PushVolumeToSlicer. Is there something like PushModelToSlicer?

Also, is PushVolumeToSlicer the only way to display a volume object on the 3d view?

Hi, see the first example in [script repository: models](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html#models)

```auto
slicer.modules.models.logic().AddModel(...)

```

Hope this helps
