Thanks! I was able to get it working with the WebXR version, and it even ran fairly quickly, at least compared to my expectations after you explained that it is really slow.
The best object I got was this very cube-ular apple:
Very cool! We are on our way to the holodeck :-)
I also tried asking for a house and a heart, and neither of those actually looked like the requested objects.
And all the objects it made seem to have their normals flipped and/or their vertices wound backwards, such that I see the inside faces of objects and the outside faces are culled. I don't know how much control you have over that, but perhaps you need to invert the normals and/or reverse the winding order of what the generator gives you?
Anyway, I hope you keep iterating on this! I'd love to see a more developed version. And, I know it probably isn't easy/cheap to host the server, having it as a WebXR experience really makes it more accessible than with all the setup.
