For some effects, it’s necessary to know which device/platform/XR mode one is on.
Does three have some central place / existing utility for this, or is that too much browser-related?
I’ve seen tons of approaches across the web that all looked hacky:
- check for the existence of specific objects in the scene
- check for domOverlayType
- parse user agent string
Concrete questions would be:
- an XR session has started, am I in VR or AR?
- an XR session has started, should I hide the background because it’s a device that shows background data (e.g. mobile AR, Hololens)
- an XR session has started, does it make sense to show a specator camera on the canvas? (e.g. makes sense on Desktop VR, but not on Quest; doesn’t make sense on Hololens etc.)
