This is pretty interesting - how has your experience been with R3F? I've built a small game level with it before and I'm wondering if I want to go all the way and build something larger.

Also, are you planning on making this open source at some point? Fabric is nice in that it manages 2D canvas objects for you & you can build things like an editor on top, in this case as a library what would you consider the primitives on top of Three objects are? Could it be used to make an editor for a 3d level?

It's great for organizing your scenes, and at least for me, it's far more readable than raw Three.js code. Unfortunately, games, especially real-time ones, don't map well to idiomatic React code. You might find yourself putting bits of game logic into various awkward places. Still, I don't think there's a better alternative for the web, except maybe Threlte if you're fine with a smaller ecosystem.

I like the fact it allows you to write clean declarative code. Imperative becomes quickly messy imo.

I’d need to find a good api to make it open source. It’s a mini ecs system handling the object states atm.

I think the main advantage over vanilla threejs would be built-in user-friendly controls and opinionated common object types (think remote glb models, plane images, etc)
