how do I determine which side is up? (Scenekit, Swift)
I make a cube (Dice) that spins around how do I determine which side are facing up
var Materials : [SCNMaterial] = [SCNMaterial(),SCNMaterial(),SCNMaterial(),SCNMaterial(),SCNMaterial(),SCNMaterial()]; // Dice
...
Materials[0].diffuse.contents = UIImage(named: "Dice5.png");
Materials[1].diffuse.contents = UIImage(named: "Dice2.png");
Materials[2].diffuse.contents = UIImage(named: "Dice3.png");
Materials[3].diffuse.contents = UIImage(named: "Dice4.png");
Materials[4].diffuse.contents = UIImage(named: "Dice1.png");
Materials[5].diffuse.contents = UIImage(named: "Dice6.png");

BoxNode.physicsBody = SCNPhysicsBody(type: SCNPhysicsBodyType.Dynamic, shape: nil)
BoxNode.physicsBody?.mass = 5
BoxNode.name = "Delete"
BoxNode.physicsBody!.applyForce(SCNVector3Make(0, 0, 14), impulse: true)
...
let Wait = SCNAction.waitForDuration(2)
let FadeOut = SCNAction.fadeOutWithDuration(1)
let Sequence = SCNAction.sequence([Move, Wait, FadeOut])
BoxNode.runAction(Sequence,completionHandler:
{
// Here I would like to determine which side that are facing up (1,2,3,4,5 or 6) - how do I do that
})
BoxNode.geometry!.materials = Materials; // set the Dice
