Sorry about that, [this link should work now[(Google Colab).
Thanks for the suggestion, I hadn’t considered that. Unfortunately it appears meshio only supports unstructured grid and not polydata. Also it appears they only support .vtk and not .vtp, which some of our users have been saving in. Plus of course we are used to VTK and switching to a different library would be a big pain.
And again, our use case generally works fine, it’s just that we get a bigger install than we might want. If there were a way to pip install subsets of VTK it might help projects like trako.
