QR Code Scanning while in WebXR

🌵 Needle Engine
1

I’m interested in using QR codes for asset lookup and placement in the AR scene. (Not image recognition) See this vid for an example I made in Unity.

I just tested a jsQR code scanning library that opens the webcam into a video element and runs the recognition on a frame of that. ( jsQR Demo )

Based on how webxr is working with needle, does it seem feasible to build this feature into a webxr site? I’d need to get this javascript plugin to pull camera data, and pass the results back to the needle scene.

Yep, you can do that - you can take a look at the WebXRCameraBackground sample for how to get a video frame right from a WebXR session, and that frame you’d probably pass through to your QR code detection library.
