Whow, I missed the notifications for this, really really cool!
I've wanted to do this for many many years, but never got to it.
However, I'm not sure ipywebrtc is the place for this particular widget.
I do wonder if we can have the marker detector and the renderer separately. In principle the only thing we need is the 4x4 matrix array (which we can jslink to say ipyvolume, ipygany etc) and a way to blend the background of the webcam with the render output.

What do you think of that?

Let's talk about it. It was a nice place to experiment though :)

I think as long as there's a way to to get a reference to the scene that has the markers, and pass that into the renderer it should work. So having them separate should be possible.
