title: Visualization on Camera Image
body: <p>I want to implement visualization on camera image. For Example: if in camera view there is any wall and closed surface you can color that surface by choosing color from colorPicker. For a reference you can see  <a href="https://play.google.com/store/apps/details?id=com.cethar.dcs.duluxcolour&amp;hl=en" rel="nofollow">dulux visualizer</a>.</p>
  
  <p>Can anyone suggest me how to implement visualizer that I have explained above?</p>
