I understand we can allow ARKit to be used by adding the
parameter to our InstantTracker initialization. I'm interested in determining at runtime whether its actually being used
This is important because it looks like some aspects of the experience (initial scale, rotation) are different under ARKit vs Wikitude's markerless tracking so we may want to tweak scale / rotation values (as well as error handling) when the runtime has selected ARKit based markerless tracking
glad to hear that our improvements are working for you.
The AR.hardware.arKitCore.deviceSupported property is what you are looking for. Note that ARKit is now enabled by default.
The model scales are rotations are looking very stable between runs and consistent in my testing between the ARKit and non ARKit versions with preview 2!
What is the new API function to tell if ARKit is in use ?
we're planning to release an updated ARKit pre-release version very soon.
There also is now a function to query whether ARKit is supported on the current device or not should you still require to differentiate for some reason.
That's fantastic news! Do all these fixes / improvements I'm reading about this morning mean an update to the Wikitude public beta will be released soon ?
the rotational offset has been fixed. The tracking pose of Wikitude's instant tracking and the ARKit instant tracking should now coincide, given that the device height is properly set for Wikitude's algorithms.
Good morning David,
currently there is no such callback, we've only added the bare necessities to the interface for now. I can, of course, understand this information to be valuable.
With the device height set correctly, Wikitude's algorithm should yield a very similar scale. There is, however, as you have found out, a rotational offset as well. This offset will be corrected in the final version of the ARKit implementation. That is something we have on our list, but simply have not gotten around to do yet.
