title: What javascript libraries or game engines to build 3D room with x, y, z co-ordinates for tracking moving objects?
body: <p>I'm building a simple demonstrator web application that will display upto 5 individual objects being tracked in real-time within a pre-defined room. I've been looking at three.js so far, but is there anything simpler, or any examples similar to my case scenario?</p>
  
  <p>For example, if my room's dimensions were 5m width, 10m length, 3m height, I would like to use a javascript library to display this and within the boundaries, update the frontend using ajax requests (or socket.io streaming data) to show the movement of upto 5 active RFID devices. The data being retrieved from the database has the following data structure:</p>
  
  <pre><code>    {
        tag_id: 'test_tag',
        time: '2017-06-13 14:00:00',
        x_coord: 3,
        y_coord: 5,
        z_coord: 10
      }
  </code></pre>
