implementation of vtk boxwidget2

Question

Currently, I am trying to write a script to select the visualized points with user interaction. I looked through vtk sources and it seems one can use widget called vtkBoxWidget2 to select. However, I can not find an example in python. My aim is to let user resize and modify the boxwidget (that's easy with the pipeline ) and then select the points inside of the box and return the selected point ids I would appreciate if anyone could share a snippet of the codes for this task in python. Thanks in advance

Answer 1

There is an example where the usage of vtkBoxWidget2 is demonstrated. It is located in the VTK source directory:

interaction/Widgets/Testing/Python/TestInteractorEventRecorder.py

Or just grab it from the VTK repository on github .
