What if we want to add a Barcode?
Here is the barcode for this example.
<!doctype HTML>
<html>
<script src="https://aframe.io/releases/1.0.4/aframe.min.js"></script>
<!-- we import arjs version without NFT but with marker + location based support -->
<script src="https://raw.githack.com/AR-js-org/AR.js/master/aframe/build/aframe-ar.js"></script>
<body style='margin : 0px; overflow: hidden;'>
<a-scene arjs='detectionMode: mono_and_matrix; matrixCodeType: 3x3;'>
<!-- marker id=0 -->
<a-marker type="barcode" value="5">
<a-sphere material="color: blue; opacity: 0.5" radius="0.25"></a-sphere>
</a-marker>
<!-- marker id=1 -->
<a-marker type="barcode" value="1">
<a-text value="Detected id:1"></a-text>
</a-marker>
<a-entity camera></a-entity>
</a-scene>
</body>
</html>
Use these barcodes.
