The app is called ThreeD . It's a React Native app for iPhone and Android, plus a small Node server that runs on your Mac and drives three engines: Apple's Object Capture, Tencent's Hunyuan3D (through ComfyUI) and a small vision model in Ollama. It's open source. In this post I'll show you what it does, how it's put together, and the things that bit me while building it.
