How can I show a moving 3D object in my Simple view Application using scene kit view with swift 4.

For example bee.glb file in windows, I am using these four files:

  1. body.bmp
  2. body.jpg
  3. volkeswagon-vw-beetle.mtl

  4. volkeswagon-vw-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
}

}

The output is:

"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"

  • This is only a guess and since no one has answered, I saw this post that I "think" is related: https://stackoverflow.com/questions/45374054/scenekit-view-renders-as-phong-instead-of-physically-based-materials – Voltan Sep 27 '19 at 15:28

i resolve this issue by Just change my file extension from .obj to .dae.Because obj file has no any animation
