# Geopipe > Geopipe uses AI and machine learning to build game-ready digital twins of real-world cities and environments. It pre-reconstructs regions at multiple levels of detail so developers can stream or download authentic, real-world 3D models into games, simulations, training, architecture, and metaverse applications without manual 3D modeling. Delivery is via streaming (Cesium 3D Tiles for Unity and Unreal), downloadable 3D meshes in common file formats, and Unity Asset Store packs. This llms.txt is generated by the API Evangelist enrichment pipeline from the Geopipe catalog entry and public surfaces. Geopipe does not currently publish a public REST API, OpenAPI specification, MCP server, or /.well-known discovery surface; delivery is through the customer web app, engine integrations, and downloadable assets. ## Product - [Geopipe home](https://geopipe.ai/): Real-world 3D city digital twins for games and simulations. - [About](https://geopipe.ai/about): Company, founders, and semantic-modeling technology. - [Create / register](https://cs.geopi.pe/register): Free account to generate and download custom areas. - [Showcase / downloads](https://geopipe.ai/download): Sample models and downloadable areas. - [3D meshes](https://geopipe.ai/3d-meshes): Download 3D meshes in the file format of your choice. ## Integrations - [Unity](https://geopipe.ai/unity): SDK, Unity Asset Store packs, and Cesium-for-Unity streaming. - [Unreal Engine](https://geopipe.ai/unreal): Cesium-for-Unreal streaming and downloadable meshes. - [Unity Asset Store publisher](https://assetstore.unity.com/publishers/57748): Ready-to-use real-world Unity asset packs. ## Source code - [github.com/geopipe](https://github.com/geopipe): Open-source geospatial / 3D-tiles toolchain. - [gltf2glb](https://github.com/geopipe/gltf2glb): GLTF to Binary GLTF (GLB) converter for Cesium batch/instance tiles. - [s2cell](https://github.com/geopipe/s2cell): Minimal Python S2 Geometry cell ID / token / lat-lon library. - [BatchGeometry](https://github.com/geopipe/BatchGeometry): Prepare Collada models for .b3dm 3D Tiles. - [PolygonSimplification](https://github.com/geopipe/PolygonSimplification): CGAL-based polygon simplification. ## News - [Blog / news](https://geopipe.ai/news): Product launches, game jams, and AI/city-scale gaming. - [Blog RSS](https://www.geopipe.ai/blog-feed.xml): RSS feed for the news blog. ## Catalog - [APIs.json](https://raw.githubusercontent.com/api-evangelist/geopipe/refs/heads/main/apis.yml): API Evangelist catalog entry for Geopipe.
