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 from vtk import * #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]))
