IOS 16.4 iPhone 11 pro max - inverted VR view

Hi

Can you confirm that in Safari and IOS 16.4 in VR mode, the view is inverted by 180 degrees? The gyroscope also works inverted...

Hi,

I can confirm - the orientation in landscape is inverted...

The reason is that with iOS 16.4 the 'Screen Orientation API' was added to Safari:
https://webkit.org/blog/13966/webkit-fea…orientation-api

But unfortunately with opposite(!) landscape rotation angles compared to Android devices,
and also opposite the 'window.orientation' angle...

So I'm not even sure if that is intended or a bug in iOS...

The krpano gyro and webvr plugins are using that Screen Orientation API preferred when it is available.
But I will change that now and prefer the usage of 'window.orientation' on iOS instead (as before) and also invert the 'Screen Orientation API' values for iOS in case if the 'window.orientation' might become removed in future and iOS keeps the current landscape rotation angles...

There will be a release today where this is fixed.

Best regards,
Klaus

Right, that's nasty!

Especially because the opposite/inverse values to all previous orientation information and implementations are used...

But maybe it's a really an iOS bug and not intention and Apple will change/fix that...

Anyway the next release should be more hardened against unexpected changes.

On beta 16.5 IOS the view is still upside down in VR mode.
