title: Making 3D plane look 2D
body: <p>I'm building a 3D app that uses SceneKit. My scene will have various 3D objects and a moveable perspective camera.</p>
  
  <p>The user can load a 2D image into the scene, which I will display on a 3D plane using the image as the material.</p>
  
  <p>What I need to be able to do is to initially show the image as if it were actually 2D, where the pixel width and height are the same as the image and it is not distorted by the camera perspective. So basically I need to know how to position that plane in relation to the camera to make it look 2D.</p>
  
  <p>Thanks in advance for any tips :)  </p>
