ARCatalog is built on excellent open-source software. Each component below is used under its own license and included unmodified. We're grateful to their authors.
3D rendering, and GLB/USDZ export. © three.js authors. Source: github.com/mrdoob/three.js
Interactive 3D and AR viewing. © Google & contributors. Bundled as a small patched fork (one-line fix to a shadow-intensity attribute bug in the Dart wrapper; upstream unaffected) — permitted and disclosed per Apache-2.0 §4(b). Source: github.com/google/model-viewer
Interactive map for placing/finding a shared model's location. © flutter_map authors, used unmodified. Source: github.com/fleaflet/flutter_map
Geographic coordinate types for the map. © latlong2 authors. Source: pub.dev/packages/latlong2
Satellite/aerial map imagery + place-name labels, attributed in-app on every map. © Esri, Maxar, Earthstar Geographics, and the GIS User Community. Currently accessed keyless (no ArcGIS account) — fine at ARCatalog's current scale, but worth moving to a registered free ArcGIS Developer API key before heavy commercial use, since Esri's documented terms are written around the registered/keyed path.
