3Dの箱を指でくるくる。簡単に作れるiPhoneアプリを描いてみます。
import UIKit
import SceneKit
class ViewController: UIViewController {
weak var sceneView : SCNView?
override func viewDidLoad() {
super.viewDidLoad()
self.setupScene()
self.createCamera()
self.createBox()
}
func setupScene() {
let sv = SCNView(frame: self.view.bounds)
sv.backgroundColor = UIColor.orangeColor()
sv.scene = SCNScene()
self.view.addSubview(sv)
self.sceneView = sv
// Auto Light
sv.autoenablesDefaultLighting = true;
}
func createCamera() {
let n = SCNNode()
n.camera = SCNCamera()
n.position = SCNVector3(x: 0, y: 0, z: 30)
self.sceneView?.scene?.rootNode.addChildNode(n)
// camera : pan gesture
self.sceneView?.allowsCameraControl = true
}
func createBox() {
let box = SCNBox(width: 10, height: 10, length: 10, chamferRadius: 1)
box.firstMaterial?.diffuse.contents = UIColor.yellowColor()
box.firstMaterial?.specular.contents = UIColor.whiteColor()
let boxNode = SCNNode(geometry: box)
self.sceneView?.scene?.rootNode.addChildNode(boxNode)
}
}
