If all you’re looking for is an example of how to integrate a marker tracker with Babylon.js rendering, our old Babylon AR extension did exactly that, connecting OpenCV’s ArUco marker tracking compiled for WebAssembly to a small TypeScript layer to make it easy to consume. I’m not familiar with the tracker you’re referencing, so I don’t know how directly you might be able to apply the same approaches for consumption in Babylon.js, but it it should at least serve as an example of how you might go about it. The approach we used was to create a Babylon.js node in the scene that a background system interacting with the tracker simply kept up-to-date; then we could parent whatever we wanted to the node, and it would move around the scene the same way the tracker saw the marker moving. The entry point to this logic is this file. Hope this helps, or at least provides an interesting reference point!
