How to animate from node in ARKit to actual view - ios

Question

I would like to get the rectangular position in the scene view of a tapped node so that I can use that position to animate another UIView from that position to a bigger size (exactly like in the Measure app):
I get the tapped node with this code, though how do I get the rect or the dimensions or whatever to make the smooth transition from the node to the view?
public override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
super.touchesBegan(touches, with: event)
guard let touch = touches.first else { return }
if (touch.view == self.sceneView) {
let viewTouchLocation:CGPoint = touch.location(in: sceneView)
guard let result = sceneView.hitTest(viewTouchLocation, options: nil).first else {
return
}
}
}
I've looked into using hitTest or smartHitTest on the scene view given the touch position but I can't really seem to be able to get the size/position of the smaller view.

Not exactly your answer but try it out: (edited to send it back)
var front = false
var boxView = UIView()
#objc func tap(_ sender: UITapGestureRecognizer){
if !front{
let position = sender.location(in: sceneView)
let hitTest = sceneView.hitTest(position, options: nil)
if let hitNode = hitTest.first?.node{
self.boxView = UIView(frame: CGRect(x: position.x, y: position.y, width: 100, height: 40))
self.boxView.backgroundColor = .red
sceneView.addSubview(self.boxView)
UIView.animate(withDuration: 0.2) {
self.boxView.frame = CGRect(x: self.sceneView.frame.width/2 - 150, y: self.sceneView.frame.height/2 - 100, width: 300, height: 200)
}
front = true
}
}else{
let p = plane.convertPosition(plane.position, to: sceneView.scene.rootNode)
print(p, plane.position) // see difference between p and plane.position
let projectedPoint = sceneView.projectPoint(p)
let point = CGPoint(x: CGFloat(projectedPoint.x), y: CGFloat(projectedPoint.y))
UIView.animate(withDuration: 0.2, animations: {
self.boxView.frame = CGRect(x: point.x, y: point.y, width: 100, height: 40)
}) { (completed) in
self.boxView.removeFromSuperview()
}
front = false
}
}
plane here is node in my test case. You might want to look about convertPosition and projectPoint
