Hello, friend,

If you want an in-scene tool to manipulate actors, then I think you might want to study the classes of the `vtk3DWidget` family: [https://vtk.org/doc/nightly/html/classvtk3DWidget.html](https://vtk.org/doc/nightly/html/classvtk3DWidget.html). For example, the `vtkBoxWidget`:

I hope this helps,

Paulo
