在Swift中使用ARKit和SCNKit创建具有起点和终点的直线,可以按照以下步骤进行:
import ARKit
import SceneKit
let arView = ARSCNView()
let configuration = ARWorldTrackingConfiguration()
arView.session.run(configuration)
let lineNode = SCNNode()
let startPoint = SCNVector3(0, 0, -1) // 起点坐标
let endPoint = SCNVector3(0, 0, -2) // 终点坐标
let lineGeometry = SCNGeometry.line(from: startPoint, to: endPoint)
这里使用了一个自定义的SCNGeometry的扩展方法line(from:to:)
,用于创建直线的几何形状。
let lineMaterial = SCNMaterial()
lineMaterial.diffuse.contents = UIColor.red // 设置直线颜色
lineGeometry.materials = [lineMaterial]
lineNode.geometry = lineGeometry
arView.scene.rootNode.addChildNode(lineNode)
完整的代码示例:
import ARKit
import SceneKit
let arView = ARSCNView()
let configuration = ARWorldTrackingConfiguration()
arView.session.run(configuration)
let lineNode = SCNNode()
let startPoint = SCNVector3(0, 0, -1)
let endPoint = SCNVector3(0, 0, -2)
let lineGeometry = SCNGeometry.line(from: startPoint, to: endPoint)
let lineMaterial = SCNMaterial()
lineMaterial.diffuse.contents = UIColor.red
lineGeometry.materials = [lineMaterial]
lineNode.geometry = lineGeometry
arView.scene.rootNode.addChildNode(lineNode)
这样就可以在Swift中使用ARKit和SCNKit创建具有起点和终点的直线了。
