GetValues

VTKExamples/Python/Arrays/GetValues

Description

Seems to work, but segfaults at the end?

Tested: No segfault in Python 2.7 and Python 3.4.

Code

GetValues.py

from __future__ import print_function

import vtk

# setup sphere
sphereSource = vtk.vtkSphereSource()
sphereSource.Update()

polydata = vtk.vtkPolyData()
polydata.ShallowCopy(sphereSource.GetOutput())

normals = polydata.GetPointData().GetNormals()
normal0 = normals.GetTuple3(0)

print("Normal0: {:3.1f} {:3.1f} {:3.1f}".format(normal0[0], normal0[1], normal0[2]))
