Im getting a Error with that.
normals = vtk.vtkPolyDataNormals()
normals.SetInputData(poly)
normals.SetFeatureAngle(1) # i dont know which angle i need
#normals.AutoOrientNormalsOn()
normals.SplittingOn()
normals.Update()
connect=vtk.vtkPolyDataConnectivityFilter()
connect.SetInputData(normals)
connect.SetExtractionModeToSpecifiedRegions()
connect.Update()
i got this error:
connect.SetInputData(normals)
TypeError: SetInputData argument 1: method requires a vtkDataObject, a vtkPolyDataNormals was provided.
Im i doing something wrong here ??
