问题 In my project I am projecting 3d files using ARKit. I am able to project Dae and Obj format models. Is there anyway I could load fbx files? 回答1: ARKit itself isn't loading models in 3D scene. It's a work for a SceneKit framework. SceneKit doesn't directly support .fbx now. You could implement a reading of .fbx file format via ModelIO but it's non-trivial thing. The best way to prepare your model for working in ARKit, SceneKit and RealityKit is to convert it into usdz file format via new

问题 I want to detect the 2D images using ARKit and RealityKit . I don't want to use SceneKit because many implementations based on RealityKit. I couldn't find any examples detecting images on RealityKit. I referred https://developer.apple.com/documentation/arkit/detecting_images_in_an_ar_experience sample code from apple. It uses Scenekit and ARSCNViewDelegate let arConfiguration = ARWorldTrackingConfiguration() arConfiguration.planeDetection = [.vertical, .horizontal] arConfiguration

问题 I'm developing a 3D game with ARKit and SceneKit. The game running smoothly at 60 fps but when I keep using it for a while the device get hot and the frame rate drop to 30 fps. The energy impact is very high and I noticed something in Instruments. I'll show the statistics and what I see in Instruments. This are the statistics when the game is running smoothly but I don't understand why I get 1.16K as the nodes count. I actually don't use so much nodes but it's just a simple level. This is

问题 I have a simple Swift ARKit setup where I have a SCNNode with a 3D object that is visible in an ARSCNView. I want to determine the 2D coordinates of this object on the ARSCNView. By this I mean the x- and y-coordinates the object has when it is drawn onto the screen. I have provided a sketch to illustrate what I mean: Is there a way to get these coordinates, or at least an approximation? I need this in order to do some further processing with the camera frame. Basically I am interested in the

问题 I have created a very simple scene ("SpeechScene") using Reality Composer, with a single speech callout object ("Speech Bubble") anchored to a Face anchor. I have loaded this scene into code via the following: let speechAnchor = try! Experience.loadSpeechScene() arView.scene.anchors.append(speechAnchor) let bubble = (arView.scene as? Experience.SpeechScene)?.speechBubble It renders as expected. However, I would like to dynamically change the text of this existing entity. I found a similar

问题 I have added content to the face anchor in Reality Composer, later on, after loading the Experience that i created on Reality Composer, i create a face tracking session like this: guard ARFaceTrackingConfiguration.isSupported else { return } let configuration = ARFaceTrackingConfiguration() configuration.maximumNumberOfTrackedFaces = ARFaceTrackingConfiguration.supportedNumberOfTrackedFaces configuration.isLightEstimationEnabled = true arView.session.delegate = self arView.session.run

问题 I'm new in ARKit. I want to create a function to rotate object. This is my code about drag and rotate object: // Rotate object @objc func rotateRecognized(sender: UIPanGestureRecognizer) { let sceneView = sender.view as! ARSCNView let swipeLocation = sender.location(in: sceneView) let hitTest = sceneView.hitTest(swipeLocation) if !hitTest.isEmpty { sender.minimumNumberOfTouches = 2 let results = hitTest.first! let node = results.node let xPan = sender.velocity(in: sceneView).x/10000 node

问题 I'm trying to use a UIView with Arkit 3D space. I've seen a few examples which requires the UIView or UIView's layer is set as the diffuse content of the SCNMaterial object. That's not working as I've expected so far. I only see the frame of the view but the subviews within it are not added neither is a corner radius on the layer visible. func setupBillBoard() { let view = PlayerView(frame: CGRect(x: 0, y: 0, width: 70, height: 40)) view.backgroundColor = .red view.layer.cornerRadius = 14 let

问题 I am trying to get the 1220 vertices data and save them to the iPhone file. The problem I am having is I could not get the captured data and write them into the JSON structure correctly. I have: struct CaptureData { var vertices: [SIMD3<Float>] var verticesFormatted : String { let v = "<" + vertices.map{ "\($0.x):\($0.y):\($0.z)" }.joined(separator: "~") + "~t:\(String(Double(Date().timeIntervalSince1970)))>" return "\(v)" } var jsonDict:Dictionary<String, Any> = [ "facetracking_data" : "1",
