如何在iOS SceneKit中使用具有不同场景图形的DAE文件

let scene = SCNScene()

if let sceneURL = Bundle.main.url(forResource: "your_dae_file", withExtension: "dae", subdirectory: "your_dae_folder") {
    if let loadedScene = try? SCNScene(url: sceneURL, options: nil) {
        // 将加载的场景添加到主场景中
        for childNode in loadedScene.rootNode.childNodes {
            scene.rootNode.addChildNode(childNode)
        }
    }
}

let scnView = SCNView(frame: CGRect(x: 0, y: 0, width: 300, height: 300))
scnView.scene = scene

view.addSubview(scnView)

let cameraNode = SCNNode()
cameraNode.camera = SCNCamera()
scene.rootNode.addChildNode(cameraNode)
cameraNode.position = SCNVector3(x: 0, y: 0, z: 10)

let lightNode = SCNNode()
lightNode.light = SCNLight()
lightNode.light?.type = .omni
lightNode.position = SCNVector3(x: 0, y: 10, z: 10)
scene.rootNode.addChildNode(lightNode)

scnView.play()
