Adding the walls of the portal

The main trick of an AR portal is based on two things: the transparency and the rendering order. We are going to create a wall with an opening (we will call it the door) in the middle, through which we will see the 3D painting. Open the Portal.swift file and follow these steps:

1. Create a new method called createWall with the following code:

func createWall(width: CGFloat, height: CGFloat, length: CGFloat)->SCNNode {    let node = SCNNode()            let wall = SCNBox(width: width, height: height, length: length, chamferRadius: 0)    wall.firstMaterial?.diffuse.contents = UIColor.white    let wallNode = SCNNode(geometry: wall)            node.addChildNode(wallNode)            return node}

Here, we created a parent node. Then, we created a box with ...
