How to change the augmented reality camera in three.js?
<p>As the example, I try to set up the AR scene in three.js. </p>

<p>I use "jsartoolkit" to do that.</p>

<p><a href="https://artoolkit.github.io/jsartoolkit5/examples/barcode_threejs.html" rel="nofollow">WebAR</a></p>

<p>I load a JSON model into the AR scene, and it does work.</p>

<p>Now I wonder how could I do to change the camera?</p>

<p>When I open the AR webpage, it always turn on the front device camera of my mobile phone.</p>

<p>I want to use the back device camera to show my WebAR scene.</p>

<p>How should I do?</p>
