Creating Immersive AR Experiences with RealityKit Creating Immersive AR Experiences with RealityKitWhat We Will BuildWe'll create an AR scene where materials on a Sphere and a Cube change in real-time as the user moves around. By detecting the user's position and orientation relative to the objects,We can generate a dynamic, engaging AR experience tracking how the user is positioned relative to objects.Key ConceptsRealityKit: Apple's highK-performance framework for 3D AR experiences.ARKit: Controls AR sessions and position tracking in the environment of AR.User Position Tracking: We can alter the textures and materials using this system, depending on the user's position related to objects.Step 1: Setting Up the Basic AR Scene with RealityKitTo get started, we'll create a RealityKit scene with ARKit to build an AR session.Import RealityKit and ARKit in your project.Create anARView, the main view for displaying RealityKit content.import RealityKitimport ARKitlet arView = ARView(frame: .zero)arView.automaticallyConfigureSession = trueThis basic AR setup creates a full-screen view that automatically manages the AR session.Step 2: Adding Objects to the SceneNext we are going to add a Sphere and a Cube to our RealityKit scene.// Create a Sphere and Cube entitylet sphere = ModelEntity(mesh: .generateSphere(radius: 0.1))let cube = ModelEntity(mesh: .generateBox(size: [0.1, 0.1, 0.1]))// Position them in the AR scenesphere.position = SIMD3(0, 0, -0.5)cube.position = SIMD3(0.3, 0, -0.5)// Add entities to the ARViewlet anchor = AnchorEntity()anchor.addChild(sphere)anchor.addChild(cube)arView.scene.anchors.append(anchor)Here, we position the Sphere and Cube slightly apart so the user can see both objects clearly.Step 3: Tracking the User's PositionTo make the experience dynamic, we have to track how the user is positioned relative to the objects. We are going to use ARKit to get the user position and orientation.func getUserPosition() -> SIMD3<Float>? {guard let cameraTransform = arView.session.currentFrame?.camera.transform else { return nil }return cameraTransform.columns.3.xyz}This is extracting the user's current position in AR space and can be called periodically for updating the user's location.Step 4: Changing Materials Based on User PositionNow we will establish the logic to update the materials of the Sphere and the Cube depending upon the orientation of the user with respect to these objects. We determine the angle between the position of the user and the position of the Sphere.func updateMaterialBasedOnUserPosition() {guard let userPosition = getUserPosition() else { return }let directionToUser = userPosition - sphere.positionlet angle = atan2(directionToUser.x, directionToUser.z)let degreeAngle = radiansToDegrees(angle)var imageName: Stringswitch degreeAngle {case 45..<135:imageName = "Texture1"case -135..<(-45):imageName = "Texture2"case -45..<45:imageName = "Texture3"default:imageName = "Texture4"}applyTexture(named: imageName, to: sphere)applyTexture(named: imageName, to: cube)}This script now scans the user's position and changes with the texture on both the Sphere and the Cube according to which direction the user is facing.Step 5: Applying Textures to ModelsTo apply the textures, we'll create a function that loads the texture and updates the material on our objects.func applyTexture(named imageName: String, to entity: ModelEntity) {if let texture = try? TextureResource.load(named: imageName) {var material = SimpleMaterial()material.color = .init(tint: .white.withAlphaComponent(0.7), texture: .init(texture))material.metallic = 0.8material.roughness = 0.2entity.model?.materials = [material]}}TheapplyTexture function loads the texture from the assets and applies it to the entity, creating a reflective, slightly metallic material with the new texture.Step 6: Continuous Position-Based UpdatesWe subscribe to the SceneEvents.Update event at the end to keep polling the user position and update material in real time.arView.scene.subscribe(to: SceneEvents.Update.self) { _ inself.updateMaterialBasedOnUserPosition()}.store(in: &cancellables)The view of the user is now being constantly tracked so that the new materials are applied because the user will move around to create this AR experience interactively.ConclusionAn augmented reality environment was created using RealityKit and ARKit, where the materials of the objects dynamically change position and appearance depending on the user's movement and position. This kind of interaction contributes to more fun and immersive AR experiences and can be generalized into more complex applications, including educational tools and interactive showcases.Did this put new fun into working with RealityKit and ARKit? Though it is a fast approach, it paves the way for building sophisticated and interactive AR environments-sometimes fun, sometimes really lifelike-with enhancement of visual fidelity from app-based implementation of real-life interactions.

AR Experiences in SwiftUI with RealityKit & Vision Pro Creating Immersive AR Experiences with SwiftUI and RealityKit:A Step-by-Step GuideWhat We Will BuildIn this tutorial, we'll focus on creating a scene where the materials of objects in the AR environment change dynamically based on the user's position relative to them. Specifically, we will manipulate a Sphere and a Cube. As the user moves around the scene, we will change the textures applied to these models based on their orientation to the user.Key ConceptsRealityKit: Apple's framework for creating 3D AR experiences.Vision Pro: Apple's spatial computing platform for detecting the user's position and movement.SwiftUI: The declarative UI framework used for building user interfaces across all Apple platforms.Step 1: Setting Up the Basic AR Scene with RealityKitIn this project, we create a view calledImmersiveView, which is powered by RealityKit'sRealityView. This view contains our AR content, which is added dynamically when the app runs.RealityView { content inTask { await visionProPose.runArSession() }if let immersiveContentEntity = try? await Entity(named: "Immersive", in: realityKitContentBundle) {// Add entities like Sphere and Cube to the content...}}Step 2: Managing User Position with Vision ProWe use a VisionProPosition object to track the user's position in the AR world. The user's position is updated every 0.3 seconds using a Timer.@State private var userPosition: SIMD3<Float>? = nilTimer.scheduledTimer(withTimeInterval: 0.3, repeats: true) { _ inTask { @MainActor inuserPosition = await visionProPose.getTransform()?.translation}}This allows us to dynamically calculate the user's movement and update the AR scene accordingly.Step 3: Dynamic Material Updates Based on User's PositionThe core of this project is dynamically changing the materials applied to the Sphere and Cube. By calculating the angle between the user's position and the Sphere, we determine which side of the Sphere the user is located on. Based on the angle, we will update the textures applied to both the Sphere and the Cube.let directionToUser = userPosition - spherePositionlet angle = atan2(directionToUser.x, directionToUser.z)let degreeAngle = radiansToDegrees(angle)switch degreeAngle {case 45..<135:imageName = "Image1"case -135..<(-45):imageName = "Image2"case -45..<45:imageName = "Image3"default:imageName = "Image4"}TheimageName determines which texture to apply to both objects, based on the direction the user is facing.Step 4: Applying Textures to ModelsNow that we have theimageName based on the user's position, we use this information to load and apply different textures to the Sphere and Cube. The textures are loaded usingTextureResource.load(named:), and the materials are updated accordingly.sphere.model?.materials = [materialForSphere(named: imageName)]cube.model?.materials = [materialForPlane(named: imageName)]Here's how we define the material creation methods for both objects:func materialForSphere(named imageName: String) -> SimpleMaterial {if let texture = try? TextureResource.load(named: imageName) {var glassMaterial = SimpleMaterial()glassMaterial.color = .init(tint: .white.withAlphaComponent(0.6), texture: .init(texture))glassMaterial.metallic = 0.9glassMaterial.roughness = 0.1return glassMaterial}return SimpleMaterial()}ThismaterialForSphere function loads the texture and creates a translucent material with a glossy finish for the Sphere, while thematerialForPlane function does the same for the Cube.Step 5: Putting It All TogetherNow that we've established our basic setup, the AR scene will continuously update based on the user's position relative to the Sphere. As the user moves, the material on both objects will change, creating an interactive experience.content.subscribe(to: SceneEvents.Update.self) { _ inupdateMaterialsIfNeeded(for: flattenedCube, sphere: sphere)}The update function checks if the user's position has changed and updates the materials of the Sphere and Cube accordingly.By combining RealityKit, Vision Pro, and SwiftUI, we can create immersive AR experiences that are dynamic and interactive. The ability to update materials based on real-time user interactions allows for highly engaging environments.In this example, we've used basic geometry and dynamic material updates, but there are endless possibilities for creating more complex interactions in AR. Whether you're building educational tools, gaming experiences, or interactive showcases, the concepts discussed here provide a foundation for more sophisticated AR development on Apple platforms.
