Yes I could make [`vtkAnatomicalOrientation`](https://gist.github.com/agirault/5efa4188be4af41e0f09311cd325b786#file-vtkanatomicalorientation-cpp-L5) a class instead, if it’s fine to embed other classes within? Do we have existing classes which only have static methods so I can check how they work? I want to make sure people don’t instantiate it.

Another solution I thought of was to embed those [static methods](https://gist.github.com/agirault/5efa4188be4af41e0f09311cd325b786#file-vtkanatomicalorientation-cpp-L7-L66) and the [`Axis`](https://gist.github.com/agirault/5efa4188be4af41e0f09311cd325b786#file-vtkanatomicalorientation-cpp-L6) direction in [`CoordinateSystem`](https://gist.github.com/agirault/5efa4188be4af41e0f09311cd325b786#file-vtkanatomicalorientation-cpp-L68) (which I would rename something like `vtkAnatomicalSpace` instead), but then I don’t know how I can declare [`LPS`](https://gist.github.com/agirault/5efa4188be4af41e0f09311cd325b786#file-vtkanatomicalorientation-cpp-L172)…
