I write a python script to read this file :slight_smile:

import vtk

filename = "hull.vtp"
reader = vtk.vtkXMLPolyDataReader()
reader.SetFileName(filename)
reader.Update()
polydata = reader.GetOutput()

but I have an error :

ERROR: In vtkXMLReader.cxx, line 341
vtkXMLPolyDataReader (000001949E6459B0): Error opening file hull.vtp

ERROR: In vtkExecutive.cxx, line 730

I have a Windows pc with VSCode and I have write this commands in terminal of VSCode :
PS C:\Users\amelie> python -m venv venv
PS C:\Users\amelie> .\venv\Scripts\activate
(venv) PS C:\Users\amelie> pip install vtk

import vtk

Understood, more investigation needed to understand why this is happening on your side.
