arkit

I want to include ARKit in an app designed for iOS10+ where I replace ARKit with SceneKit if the iOS version is <11. Unfortunately it seems like there is no way to currently do this? Depending on how you've set your expectations, it is possible to use SceneKit as a "fallback" from ARKit -- specifically, from ARSCNView . What you can easily do is create a 3D content experience that appears "in the real world" via AR when running on an ARKit capable device, and in an entirely virtual setting (that is, rendered in 3D without a camera feed as background) when running without ARKit. Note: ARKit

I have a simple SCNNode in ARKit and I am trying to drag it wherever I moved my finger on the phone. Here is my code. @objc func pan(recognizer :UIGestureRecognizer) { guard let currentFrame = self.sceneView.session.currentFrame else { return } var translation = matrix_identity_float4x4 translation.columns.3.z = -1.5 let sceneView = recognizer.view as! ARSCNView let touchLocation = recognizer.location(in: sceneView) let hitTestResult = sceneView.hitTest(touchLocation, options: [:]) if !hitTestResult.isEmpty { print("hit result") guard let hitResult = hitTestResult.first else { return } let

I'm trying out the new ARKit to replace another similar solution I have. It's pretty great! But I can't seem to figure out how to move an ARAnchor programmatically. I want to slowly move the anchor to the left of the user. Creating the anchor to be 2 meters in front of the user: var translation = matrix_identity_float4x4 translation.columns.3.z = -2.0 let transform = simd_mul(currentFrame.camera.transform, translation) let anchor = ARAnchor(transform: transform) sceneView.session.add(anchor: anchor) later, moving the object to the left/right of the user (x-axis)... anchor.transform.columns.3.x

In my ARKit app I am presenting a modal window. When I close the modal and go back to the ARSCNView then I find out that the session is paused due to this code: override func viewWillDisappear(_ animated: Bool) { super.viewWillDisappear(animated) // Pause the view's session sceneView.session.pause() } When I close the modal and go back to the ARKit camera view screen this code gets fired: override func viewWillAppear(_ animated: Bool) { super.viewWillAppear(animated) // Create a session configuration let configuration = ARWorldTrackingSessionConfiguration() // Run the view's session sceneView

I've managed to get a cube (SCNNode) placed on a surface where the camera is pointed, however I am finding it very difficult to do the simple (?) task of also placing text in the same position. I've created the SCNText and subsequent SCNNode, however when I add it to the rootNode the text always seems to be added above my head and off the camera to the right (which tells me thats the global origin point). Even when I use the exact same values of position I used for the the cube, the SCNText node still gets placed above my head in the same spot. Apologies if this is a basic question, I've never

I'm in the process of learning both ARKit and Scenekit concurrently, and it's been a bit of a challenge. With a ARWorldTrackingSessionConfiguration session created, I was wondering if anyone knew of a way to get the position of the user's 'camera' in the scene session. The idea is I want to animate an object towards the user's current position. let reaperScene = SCNScene(named: "reaper.dae")! let reaperNode = reaperScene.rootNode.childNode(withName: "reaper", recursively: true)! reaperNode.position = SCNVector3Make(0, 0, -1) let scene = SCNScene() scene.rootNode.addChildNode(reaperNode) //
