title: Scenekit shape between 4 points
body: <p>Given that the route I was taking in a previous question:</p>
  
  <p><a href="https://stackoverflow.com/questions/45264298/arkit-place-a-scnplane-between-2-vector-points-on-a-plane-in-swift-3">ARKit - place a SCNPlane between 2 vector points on a plane in Swift 3</a></p>
  
  <p>...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.</p>
  
  <p>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.</p>
  
  <p>Thanks</p>
