I have this code to make ARVR Stereo View To Be Used in VR Box Or Google Cardboard, it uses iOS 18 New RealityView but it is not Act as an AR but rather Static VR on a Camera background so as I move the iPhone the cube move with it and that's not suppose to happen if its Anchored in a plane or to world coordinate.
import SwiftUI
import RealityKit
struct ContentView : View {
let anchor1 = AnchorEntity(.camera)
let anchor2 = AnchorEntity(.camera)
var body: some View {
HStack (spacing: 0){
MainView(anchor: anchor1)
MainView(anchor: anchor2)
}
.background(.black)
}
}
struct MainView : View {
@State var anchor = AnchorEntity()
var body: some View {
RealityView { content in
content.camera = .spatialTracking
let item = ModelEntity(mesh: .generateBox(size: 0.25), materials: [SimpleMaterial()])
anchor.addChild(item)
content.add(anchor)
anchor.position.z = -1.0
anchor.orientation = .init(angle: .pi/4, axis:[0,1,1])
}
}
}
the thing is if I remove .camera
like this
let anchor1 = AnchorEntity()
let anchor2 = AnchorEntity()
It would work as AR Anchored to world coordinates but on the other hand is does not work but on the left view only not both views
Meanwhile this was so easy before RealityView and SwiftUI by cloning the view like in ARSCNView Example :
import UIKit
import ARKit
class ViewController: UIViewController, ARSCNViewDelegate, ARSessionDelegate {
//create Any Two ARSCNView's in Story board
// and link each to the next (dont mind dimensions)
@IBOutlet var sceneView: ARSCNView!
@IBOutlet var sceneView2: ARSCNView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
sceneView.delegate = self
sceneView.session.delegate = self
// Create SceneKit box
let box = SCNBox(width: 0.1, height: 0.1, length: 0.1, chamferRadius: 0.01)
let item = SCNNode(geometry: box)
item.geometry?.materials.first?.diffuse.contents = UIColor.green
item.position = SCNVector3(0.0, 0.0, -1.0)
item.orientation = SCNVector4(0, 1, 1, .pi/4.0)
// retrieve the ship node
sceneView.scene.rootNode.addChildNode(item)
}
override func viewDidLayoutSubviews() // To Do Add the 4 Buttons
{
// Stop Screen Dimming or Closing While The App Is Running
UIApplication.shared.isIdleTimerDisabled = true
let screen: CGRect = UIScreen.main.bounds
let topPadding: CGFloat = self.view.safeAreaInsets.top
let bottomPadding: CGFloat = self.view.safeAreaInsets.bottom
let leftPadding: CGFloat = self.view.safeAreaInsets.left
let rightPadding: CGFloat = self.view.safeAreaInsets.right
let safeArea: CGRect = CGRect(x: leftPadding, y: topPadding, width: screen.size.width - leftPadding - rightPadding, height: screen.size.height - topPadding - bottomPadding)
DispatchQueue.main.async
{
if self.sceneView != nil
{
self.sceneView.frame = CGRect(x: safeArea.size.width * 0 + safeArea.origin.x, y: safeArea.size.height * 0 + safeArea.origin.y, width: safeArea.size.width * 0.5, height: safeArea.size.height * 1)
}
if self.sceneView2 != nil
{
self.sceneView2.frame = CGRect(x: safeArea.size.width * 0.5 + safeArea.origin.x, y: safeArea.size.height * 0 + safeArea.origin.y, width: safeArea.size.width * 0.5, height: safeArea.size.height * 1)
}
}
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
let configuration = ARWorldTrackingConfiguration()
sceneView.session.run(configuration)
sceneView2.scene = sceneView.scene
sceneView2.session = sceneView.session
}
}
And here is the video for it
