what is brickbuilderai fr?

BrickBuilder is a web app that turns a photo or text description into a buildable LEGO-compatible brick model. You upload an image or type what you want, and within about 30 seconds you get a 3D brick model you can rotate in the browser, view step-by-step building instructions for, download as an LDR or MPD file that works with LEGO digital design tools, or use as a parts list to order physical bricks. The process goes through several steps. An AI model first reconstructs a 3D shape from the input. Two options are available: Trellis for simpler use, and SAM-3D for better quality (SAM-3D requires a separate GPU-powered worker hosted on RunPod). The 3D shape is then broken down into voxels (a 3D grid of cubes), and an optimizer converts those voxels into real LEGO-compatible bricks that fit together correctly. The project is split into three parts: a React and TypeScript frontend with a 3D viewer built on Three.js, a Python FastAPI backend that handles image processing and brick optimization, and an optional serverless worker for the SAM-3D pipeline running on a cloud GPU. Optional integrations include Supabase for storage and Stripe for payments, but both are optional: a local PostgreSQL database runs automatically if Supabase is not configured. To run it locally you need Python 3.10 or later, Node.js, the uv Python package manager, and a free API key from fal.ai. Two commands handle installation and startup. The higher-quality SAM-3D path requires deploying a public Docker container to RunPod with a GPU.
