title: How to place 3D model using ARKit iOS 11 with some custom background view without using camera?
body: <p>I am working on an Augmented Reality iOS app for which i am using ARKIT of iOS 11 beta. I am using ARSCNView(SceneKit) to render my .scn object. I have followed the sample given by apple in order to create an ARSession(<a href="https://developer.apple.com/sample-code/wwdc/2017/PlacingObjects.zip" rel="nofollow noreferrer">https://developer.apple.com/sample-code/wwdc/2017/PlacingObjects.zip</a>). Is it possible to place the 3D model with custom background instead of camera? </p>
  
  <p>Like user can select the background color or can provide custom 2D photos as background?</p>
