Hi Wikitude Team:
How can I do to make it?
Sorry , I use Android Studio to develop , I am afraid that I cannot help you.
You can start new topic to ask in forum.
Do you need my account to discuss with me?
Yes , in the sample code - simpleinstanttracking.js
try to add trackingPlaneOrientation below deviceHeight
I have found this trackingPlaneOrientation parameter in AR.InstantTracker Class to make it.
