This is the intended behavior of vtkCamera.Elevation. It does not change the direction of vtkCamera.ViewUp, and so when the camera direction passes through ViewUp, the direction of "up" changes. The advantage of not changing viewUp is that the model stays right-side up, preventing disorientation. If you want viewUp to change for your use case, call vtkCamera.OrthogonalizeViewUp() after each call to vtkCamera.Elevation(), or use vtkMRMLCameraNode::RotateAround()
