ARKit – 环境遮挡

Har*_*ris 4 unity-game-engine swift arkit swiftui realitykit

在 Unity 中,我们可以使用环境深度来实现遮挡。它在幕后使用 ARKit。我如何在 iOS ARkit 中实现相同的行为。

我知道我们可以用深度配置帧语义,但我怀疑它真的与统一环境深度遮挡相同吗?

// Build the set of required frame semantics.
let semantics: ARConfiguration.FrameSemantics = [.sceneDepth]
configuration.frameSemantics = semantics

session.run(configuration)

在 ARKit 中实现sceneReconstruction选项,并在 RealityKit 中打开.occlusion.

唯一的缺点是一个丑陋的面具,在现实世界的物体周围有软扩张的边缘......

import RealityKit
import SwiftUI
import ARKit

struct ContentView: View {
    var body: some View {
        return ARContainer().ignoresSafeArea()
    }
}

struct ARContainer: UIViewRepresentable {

    func makeUIView(context: Context) -> ARView {  
        let arView = ARView(frame: .zero)
        arView.cameraMode = .ar
                
        arView.automaticallyConfigureSession = false
        let config = ARWorldTrackingConfiguration()
        config.sceneReconstruction = .mesh
        arView.session.run(config)

        arView.environment.sceneUnderstanding.options = .occlusion

        let box: MeshResource = .generateBox(size: 0.5)
        let material = SimpleMaterial(color: .green, isMetallic: true)
        let entity = ModelEntity(mesh: box, materials: [material])
        let anchor = AnchorEntity(world: [0,0,-1.5])
        anchor.addChild(entity)
        arView.scene.anchors.append(anchor)            
        return arView
    }       
    func updateUIView(_ uiView: ARView, context: Context) { }
}
