Marker Based Tracking Demo Issues

[JPHelios]

Hello everyone,

I am aiming for using AR.js for a new AR project in combination with machine learning on work. The goal is to recognize objects in the camera input, label them with yolov5 and then set special objects as marker for image tracking. Before implementing the Ar part of the project I just wanted to check out AR.js and some demo programs that are provided in this project. During the last couple of hours I wasted my time on trying to use the program linked in the readme (https://ar-js-org.github.io/AR.js/aframe/examples/image-tracking/nft/) to get a nice Trex animation drawn on this image (https://raw.githubusercontent.com/AR-js-org/AR.js/master/aframe/examples/image-tracking/nft/trex-image-big.jpeg).

Actually it should be easy going because it is a demo app but somehow nothing is animated. I tried all devices I have (laptop, mobile and tablet) and changed position, distance, etc. a lot.

Maybe some of you just can check if the demo is working and the issue is on my side or not. Or if you have other advices I am happy to hear them.

Thanks for your help.
