question: is north always -y and east +x

[tom-twinlabs]

This is what it looks like to me, by adding AxesHelper, I just wanted to ask if this is always the case?

Many thanks

I was considering letting the user pick the camera UP vector, so you can decide what North East are, but at the moment is kinda following defaults threejs behaviour, where Y is UP and X is right and -Z forward.

So north is -z and east is +x.

        N
       - z

W - x   ⨁   + x E

       + z
        S

It shouldn't be hard to have +Y for north instead, and would make more sense for a lot of cases. PRs are welcomed for that feature 😄

Thank you for the response!

I actually don't have a need to change camera.up at the moment. Aligning with default three.js behavior makes total sense. I will make a small PR for a docs addition, but feel free to ignore it :)
