Implementation plan

• Adding picture in picture view to the side of the display to show depth map view
• Depth view will automatically show up without the need to click any button
• Changing server side code to send multiple frame types along side the point cloud data
  • Server will send depth data in json array
  • web app will parse the array data and construct images on the fly
