SceneKit-PortalMask
See my Medium post about this CocoaPod
This class PortalMask creates an occluding box around any rectangular frame, including a tracking image, which turns the tracking image or any static area into an Augmented Reality portal into a scene you can define inside that area that can be seen by looking through the defined portal. This can also be used to have the illusion of a hole in the ground.
Include this pod in your project: pod 'PortalMask'
The following example code creates a portal ontop of a tracking marker, similar to the example gif.
func renderer(_ renderer: SCNSceneRenderer, didAdd node: SCNNode, for anchor: ARAnchor) {
if let imageAnchor = anchor as? ARImageAnchor {
let nodeRotated = SCNNode()
nodeRotated.eulerAngles.x = -.pi / 2
// the next 2 lines add the portal
let portal = PortalMask(frameSize: imageAnchor.referenceImage.physicalSize)
nodeRotated.addChildNode(portal)
// the next 4 lines add a cube inside the image area
let width = imageAnchor.referenceImage.physicalSize.width
let boxNode = SCNNode(geometry: SCNBox(width: width, height: width, length: width, chamferRadius: 0))
boxNode.position.z = -boxNode.width
nodeRotated.addChildNode(boxNode)
node.addChild(nodeRotated)
}
}
Also contains functions for circular holes:
let portal = PortalMask(radius: imageAnchor.referenceImage.physicalSize.width)
And any other polygon by feeding coordinates. This example will make a triangular portal:
let portal = PortalMask(path: [CGPoint(x: 1, y: -1), CGPoint(x: 0, y: 1), CGPoint(x: -1, y: -1)])
Here's some basic examples of what you can do with this Pod:
