具有移动对象的场景套件视图

Question

如何使用带有 swift 4.

的场景套件视图在我的简单视图应用程序中显示移动的 3D 对象

例如windows中的bee.glb文件，我正在使用这四个文件：

body.bmp
body.jpg
大众-大众-beetle.mtl

大众-大众-beetle.obj

import UIKit
import SceneKit
import ARKit

class ViewController: UIViewController {

@IBOutlet weak var sceneView: SCNView!

override func viewDidLoad() {
super.viewDidLoad()


// 1: Load .obj file
let scene = SCNScene(named: "volkeswagon-vw-beetle.obj")

// 2: Add camera node
let cameraNode = SCNNode()
cameraNode.camera = SCNCamera()
// 3: Place camera
cameraNode.position = SCNVector3(x: 0, y: 10, z: 35)
// 4: Set camera on scene
scene!.rootNode.addChildNode(cameraNode)

// 5: Adding light to scene
let lightNode = SCNNode()
lightNode.light = SCNLight()
lightNode.light?.type = .omni
lightNode.position = SCNVector3(x: 0, y: 10, z: 35)
scene?.rootNode.addChildNode(lightNode)

// 6: Creating and adding ambien light to scene
let ambientLightNode = SCNNode()
ambientLightNode.light = SCNLight()
ambientLightNode.light?.type = .ambient
ambientLightNode.light?.color = UIColor.darkGray
scene?.rootNode.addChildNode(ambientLightNode)

// Allow user to manipulate camera
sceneView.allowsCameraControl = true

// Show FPS logs and timming
 sceneView.showsStatistics = true

// Set background color
sceneView.backgroundColor = UIColor.white

// Allow user translate image
sceneView.cameraControlConfiguration.allowsTranslation = false

// Set scene settings
sceneView.scene = scene
}

}

输出为：

"3DVideo[6430:105708] [SceneKit] Error: Physically based lighting model is not supported by the OpenGL renderer, using Phong instead (3) 2019-09-02 03:29:13.297536-0700 3DVideo[6430:105708] [SceneKit] Error: Physically based lighting model is not supported by the OpenGL renderer, using Phong instead (2) 2019-09-02 03:29:13.308381-0700 3DVideo[6430:105708] [SceneKit] Error: Physically based lighting model is not supported by the OpenGL renderer, using Phong instead"

Answer 1

我通过将我的文件扩展名从 .obj 更改为 .dae.Because obj 文件没有任何动画来解决此问题
