Hey

Simplifying my last post and deleting it

I’m using vtk python(8.1.0) in Anaconda. I’ve read polygon data in from .vtp files using vtkXMLPolyDataReader() and have a vtkPolyData object. I would like to update its Cell data to include additional vector data. I haven’t been able to figure this out - there is no SetCellData method. Any suggestions? Is this even possible?

Thanks
