equivalent of rotationAngle from Touch Events?

[patrickhlauke]

Though hardware support doesn't seem all too great (I had to go on the hunt for a second-hand Nexus 10 in order to test/add this to my tracker demo), wondering if there's mileage in spec-ing something equivalent to Touch Events' rotationAngle in version 2?

If yes, how would this affect width/height? Would we still want to keep them as the rectangular bounding box (aligned with the screen axes), or modify them to act as radiusX/radiusY?

This may even be seen as a generalisation of #25 - not exclusive to pen/stylus, but to touch as well, as conceptually they're the same?

I'd rather not conflate this with #25 myself, they're not really the same thing. For one, touch contact geometry has a range of 180° where pen rotation has a range of 360°.

I'm not opposed to adding this, but given that hardware and OS support is so rare I don't personally think it's worth it (AFAIK Android Nexus 10 would be the only platform that would benefit). If hardware support were to increase then I'd consider it more important.

Closing this, as I'd rather see a proper implementation of #25 than TouchEvents' half-baked (in my opinion) rotationAngle
