如何像测量应用程序一样在ARKit (SceneKit)中绘制虚线？

import ARKit
import SceneKit

func createDashedLine() -> SCNNode {
    // 定义虚线的顶点数据
    let vertices: [SCNVector3] = [
        SCNVector3(0, 0, 0),
        SCNVector3(1, 0, 0),
        SCNVector3(2, 0, 0),
        SCNVector3(3, 0, 0)
    ]
    
    // 定义虚线的连接方式
    let indices: [UInt32] = [
        0, 1,
        1, 2,
        2, 3
    ]
    
    // 创建虚线的几何体
    let source = SCNGeometrySource(vertices: vertices)
    let element = SCNGeometryElement(indices: indices, primitiveType: .line)
    let geometry = SCNGeometry(sources: [source], elements: [element])
    
    // 设置虚线的材质属性
    let material = SCNMaterial()
    material.diffuse.contents = UIColor.red
    geometry.materials = [material]
    
    // 创建节点并设置几何体
    let node = SCNNode()
    node.geometry = geometry
    
    return node
}

// 在ARKit场景中添加虚线节点
let sceneView = ARSCNView()
let dashedLineNode = createDashedLine()
sceneView.scene.rootNode.addChildNode(dashedLineNode)
