Accessing a list of a Model's Vertices programmatically?

How would you go about accessing a list of a model’s vertices programmatically once a model has been added to the scene?

This example is for fiber bundles but the access to the poly data is the same with slicer.util.arrayFromModelPoints.

Alright thank you very much.
