Get All ARAnchors of focused Camera in ARKIT

Question

When application launched first a vertical surface is detected on one wall than camera focus to the second wall, in the second wall another surface is detected. T

Answer 1

In order to get the node that is currently is in point of view you can do something like this:

       var targettedAnchorNode: SCNNode?
       if let anchors = sceneView.session.currentFrame?.anchors {
           for anchor in anchors {

               if let anchorNode = sceneView.node(for: anchor), let pointOfView = sceneView.pointOfView, sceneView.isNode(anchorNode, insideFrustumOf: pointOfView) {
                   targettedAnchorNode = anchorNode
                   break
               }
           }

           if let targettedAnchorNode = targettedAnchorNode {
               addNode(position: SCNVector3Zero, anchorNode: targettedAnchorNode)
           } else {
               debugPrint("Targetted node not found")
           }

       } else {
           debugPrint("Anchors not found")
       }

If you would like to get all focused nodes, collect them in an array satisfying specified condition

Good luck!
