map3d Turns OpenStreetMap into GLB Cities

map3d’s value is the asset handoff: developers can move from map data to usable 3D geometry without building a GIS pipeline first. Its main limitation is data quality, not rendering—OSM building attributes vary widely by region, making this a white-box generator rather than survey-grade mapping.

• –React Three Fiber keeps the workflow accessible to web developers already using React and Three.js.
• –GLB export makes the generated scenes portable across common 3D tools and engines.
• –OpenStreetMap provides broad geographic coverage without proprietary map-data costs.
• –Missing height values can produce misleading building volumes, especially outside well-mapped areas.
• –Planned textures, height customization, materials, and heightmaps could make it more useful for production visualization.
