This is live for preview over at https://needle-ar.glitch.me/
I will share a github repository if others are interested in collaborating on this, so far I have just sorted functionality for spawning a product model and a floor plane that is large to move it around on. Scale and Rotate work with two finger touches.
I am hoping to figure out how to show and raycast against AR detected planes over here which will remove the need for a large floor plane to raycast against Unknown
