使用柱面/路径连接Swift Scenekit中的多个SCNObjects

import UIKit
import SceneKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建柱面节点
        let cylinder = SCNCylinder(radius: 0.1, height: 1)
        let cylinderNode = SCNNode(geometry: cylinder)
        cylinderNode.position = SCNVector3(0, 0, 0) // 设置柱面节点的位置
        
        // 创建柱面父节点
        let cylinderParentNode = SCNNode()
        cylinderParentNode.addChildNode(cylinderNode)
        
        // 创建需要连接的SCNNode对象
        let object1 = SCNBox(width: 0.2, height: 0.2, length: 0.2, chamferRadius: 0)
        let object1Node = SCNNode(geometry: object1)
        object1Node.position = SCNVector3(0, 0, -0.5) // 设置第一个对象的位置
        
        let object2 = SCNPyramid(width: 0.2, height: 0.2, length: 0.2)
        let object2Node = SCNNode(geometry: object2)
        object2Node.position = SCNVector3(0, 0, 0.5) // 设置第二个对象的位置
        
        // 将需要连接的SCNNode对象添加到柱面父节点
        cylinderParentNode.addChildNode(object1Node)
        cylinderParentNode.addChildNode(object2Node)
        
        // 使用SCNLookAtConstraint来确保柱面父节点的朝向
        let constraint = SCNLookAtConstraint(target: object1Node)
        cylinderParentNode.constraints = [constraint]
        
        // 在SceneKit场景中显示柱面父节点
        let sceneView = SCNView(frame: view.frame)
        view.addSubview(sceneView)
        let scene = SCNScene()
        scene.rootNode.addChildNode(cylinderParentNode)
        sceneView.scene = scene
    }
