How do I attach an image to the reference frame in argon so that it moves with the camera based wherever the user points the phone? Basically, I want it to be like a HUD, and in my case, it will just be a still image that I've designed in photoshop that I want to work like a map key.
I've tried the following based on some A-Frame documentation, but it doesn't seem to be working. It doesn't seem to alter the application at all. I put this within my ar-scene.
<ar-camera>
<a-entity>
<a-image src="#imgKey" width="4" height="2" scale="1 1 1" position="0 0 0">
</a-image>
</a-entity>
</ar-camera>
Any ideas?
