ARKit/RealityKit – 人物遮挡配置不起作用

Question

由于某种原因，即使我在 Stackoverflow 上查看了某人的问题，我也无法让人们使用遮挡。这是我的代码：

//Load ARView
let arView = ARView(frame: .zero)

//Load people occlusion
let session = ARSession()

if let configuration = session.configuration as? ARWorldTrackingConfiguration {
    configuration.frameSemantics.insert(.personSegmentationWithDepth)
    session.run(configuration)
}

//Load custom model(not in use)
let model = try! Entity.loadModel(named: "Mug")

//Load Anchor + Entity
let anchor = AnchorEntity(plane: .horizontal)
let box = MeshResource.generateBox(size: 0.1)
let material = SimpleMaterial(color: .red, isMetallic: true)
let entity = ModelEntity(mesh: box, materials: [material])
arView.scene.anchors.append(anchor)
anchor.addChild(entity)
return arView

我错过了什么？

您的代码应如下所示：

let arView = ARView(frame: .zero)

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {

    self.switchOcclusion()
}
    
fileprivate func switchOcclusion() {
        
    guard let config = arView.session.configuration as ARWorldTrackingConfiguration
    else { return }
        
    guard ARWorldTrackingConfiguration.supportsFrameSemantics(.personSegmentationWithDepth)
    else { return }
        
    switch config.frameSemantics {            
        case [.personSegmentationWithDepth]: config.frameSemantics.remove(.personSegmentationWithDepth)                    
        default: config.frameSemantics.insert(.personSegmentationWithDepth)
    }           
    arView.session.run(config)
}
