Tap location on SCNNode in arkit ios swift

scnnode tap

arkit move node

I placed node1 to sceneview.I also added node2 as childnode to node1 when tapped on node1.But I am not able to place node2 correctly at tap location on node1.How can I place it exactly at tap location of scn node in arkit.

Final Code

let sceneView = sender.view as! ARSCNView
let tapLocation = sender.location(in: sceneView)
let hitTest = sceneView.hitTest(tapLocation, options: [:])
guard let node = hitTest.first?.node.parent
if let hitTest = hitTest.first
{
    guard let scene = SCNScene(named: "furnitures.scnassets/(furnitureName).scn") else{return}
    let childnode = (scene.rootNode.childNode(withName: furnitureName + " " + "parentnode", recursively: false))!
     node.addChildNode(childnode)
     childnode.position = hitTest.localCoordinates
     childnode.scale = SCNVector3(0.5,0.5,0.5)
 }

You need to use SCNHitTestResult localCoordinates or worldCoordinates this depend of which one is better for your problem, then you can add a node on that position

this is a example code

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    let scnView = self.view as! SCNView
    let touch = touches.first
    if let point = touch?.location(in: scnView) {
        let hitResults = scnView.hitTest(point, options: nil)
        if let result: SCNHitTestResult = hitResults.first {
            let position  = result.localCoordinates
            let position2  = result.worldCoordinates
        }
    }
}

Tap gesture recognizer for object in SceneKit / ARKit, But I am not able to place node2 correctly at tap location on node1.How can I place it exactly at tap location of scn node in arkit. when you're working arscnview, there 2 kinds of hit testing can do, , use entirely separate code paths.. use arkit method hittest(_:types:) if want hit test against real world (or @ least, against arkit's estimate of real-world features are). returns arhittestresult objects, tell real-world features detected planes. in other words, use method if want find real object can see , touch without

This is my code.I didnot know how to mention in comment so I posted like this

let sceneView = sender.view as! ARSCNView
let tapLocation = sender.location(in: sceneView)
let hitTest = sceneView.hitTest(tapLocation, options: [:])
guard let node = hitTest.first?.node
if let hitTest = hitTest.first
{
    guard let scene = SCNScene(named: "furnitures.scnassets/(furnitureName).scn") else{return}
    let childnode = (scene.rootNode.childNode(withName: furnitureName + " " + "parentnode", recursively: false))!
     node.addChildNode(childnode)
     childnode.position = hitTest.localCoordinates
     childnode.scale = SCNVector3(0.5,0.5,0.5)
 }

How to add Gestures to SCNNode in …, I've been playing around with ARKit lately, tapping and object on the scene is very useful when interacting with objects, this snippet will add a  When UITap Gesture Recognizer detects a tap on the screen, the handle Scene Tap method uses ARKit hit-testing to find a 3D point on a real-world surface, then places an ARAnchor marking that position. When ARKit calls the delegate method renderer(_: did Add: for:), the app loads a 3D model for ARSCNView to display at the anchor’s position.

  • where is your code ? you tried?
  • I posted plz check and help...
  • Thank you Melian..I did the same but the node2 is not placed at tap location.Is it related to node1 position or pivot?
  • Did you try both positions? @AnushaCheedella, can you provide your current code?
  • @AnushaCheedella if you are adding the new node into the touched one you need localCoordinates if you re adding Node2 into scene then you need WorldCoordinates
  • I had added your answer as update in your question, now you can remove the answer if your want to
  • Did my answer help to fix your problem?
  • I am sorry bcz I am asking too many questions.I am beginner so I have many questions.Your answer helped me...In my first case I want to add a vase on chair..In this case everything is perfect.But when I add it on a table the vase is soo negligeble that I cannot see it..May I know where is the issue//
  • What you mean with "is soo negligeble"?
  • negligible means the size is so small when compared to when it is placed on chair
  • Check the scale of the parent node , and the size of the parent node related to the vase object size
