It seems that I can set [transform to the vtkCamera](https://discourse.vtk.org/t/scaling-a-rendering-scene/173/4?u=kerim). And I tested with VTK 9.0.1 it works.

```cpp
  vtkNew<vtkTransform> transform;
  transform->Scale(2, 1, 1);

  renderer->GetActiveCamera()->SetModelTransformMatrix(transform->GetMatrix());

```

Though there are some problems that is connected with `vtkCubeAxesActor`.

P.S. as I have previously created [topic dedicated to adding vtkCubeAxesActor to the Slicer’s scene](https://discourse.slicer.org/t/add-an-actor-vtkcubeaxesactor-to-the-scene-in-c/19294), I think I should discuss the mentionned problem there.
