DGArt Smiley Box to Playground

Using SceneKit in Swift Playground Demo 3 : iPadOS

Create your 3D model using DGArt and import it into the Playground App for your own app project. The example SmileyBox was modeled using DGArt and used in the Playground app. And the 3D scene contains a "Smiley" node and "Floor" node.

Make the smiley bounce while rotating using the

Import the .scn file into the Playgrounds app using the following steps: Edit the ContentView code as shown below:

import SwiftUI
import SceneKit

struct ContentView: View {
    var scene: SCNScene? {
        let scene = SCNScene(named: "SmileyBox.scn")
        // set scene background color
        scene?.background.contents = UIColor.init(red: 0.6, green: 0.1, blue: 0.6, alpha: 1.0)
        let Smiley = scene?.rootNode.childNode(withName: "Smiley", recursively: true)
        let moveUp = SCNAction.move(by: SCNVector3(0.0, 2.0, 0.0), duration: 0.8)
        moveUp.timingMode = .easeOut
        let moveDown = SCNAction.move(by: SCNVector3(0.0, -2.0, 0.0), duration: 0.8)
        moveDown.timingMode = .easeIn
        let moveMotion = SCNAction.sequence([moveUp, moveDown])
        let rotation = SCNAction.rotateBy(x: 0, y: 1, z: 0, duration: 1.6)
        let motion =[moveMotion, rotation])
        return scene
    var cameraNode: SCNNode? {
        let cameraNode = SCNNode() = SCNCamera()
        cameraNode.position = SCNVector3(x: 5, y: 5.5, z: 5)
        cameraNode.look(at: SCNVector3(x: 0, y: 1, z: 0))
        return cameraNode
    var body: some View {
            scene: scene,
            pointOfView: cameraNode,
            options: [

Finally, you will be able to see the Smiley Box animation appear beside.
