Open-Source Tool map3d Turns OpenStreetMap Data Into Downloadable 3D City Models

A new open-source project called map3d lets anyone convert real-world OpenStreetMap data into a rotatable 3D city model directly inside a web browser, then export it as a file usable in game engines and 3D software. Built by a developer known on GitHub as cartesiancs, map3d pulls building footprints, heights, and road networks from OpenStreetMap and extrudes them into three-dimensional geometry using React-Three-Fiber, the React renderer for the Three.js graphics engine.
