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 to render objects over lines drawn in Just a Line AR App .But when i am trying to include arfragment, " app is not able to find a place to draw line ".Also when i am trying to include view renderable class for showing 2d texts into 3d scene,i am getting this error: "No implementation found for long com.google.android.filament.Stream.CreateBuilder()". Any idea on how to resolve this issue? 来源： https://stackoverflow.com/questions/62592904/how-to-render-objects-in-just-a-line-ar-app

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 am creating an app where I need to change textures(pattern) of my 3d object. I am using AR Core SDK and android. I have used the below code but it is not working. Texture.builder() .setSource(this,R.drawable.fabric3) .build() .thenAccept(t -> { BaseTransformableNode node = arFragment.getTransformationSystem().getSelectedNode(); if(node!=null){ node.getRenderable().getMaterial().setTexture("baseColorMap",t); } }); Documentation is also not helping me much. This is my SFA file { animations: [
