Given that the route I was taking in a previous question:
ARKit - place a SCNPlane between 2 vector points on a plane in Swift 3
...seems to be flawed, I'm looking at other options. I can draw a line between 2 nodes, I can then create nodes above those, effectively in a square but even if I draw lines between them all, I can't make that into a shape. Is it possible in Scenekit to draw a shape (square) where each of the 4 corners joins to a node.
I can create a plane, position it on a node, transform the pivot and then rotate but it doesn't always work but SCNGeometry lines do.
Thanks
