**Current Situation:**

- I am using an implmentation of `vtkInteractorStyleTrackballCamera` for my interator/camera.
- I want the camera to only adjust it’s Yaw/Pitch when rotated by the user

**Question:**

- What would be the best way to **exclusively disable the Roll** of the Camera’s rotation?
