3D Models (GLB & GLTF)

Import 3D models in glTF format to place detailed objects — buildings, infrastructure, equipment, vehicles — at precise locations on the globe.

Supported formats​

FormatExtensionNotes
Binary glTF.glbSelf-contained; preferred format
Text glTF.gltfThe companion .bin buffer is embedded automatically during import

Importing​

  1. Open the Layers panel and click +.
  2. Select Import file and choose your .glb or .gltf file (max 100 MB).
  3. The model is uploaded and appears on the map.
note

For .gltf files, AugmentCity reads the companion .bin buffer from disk and inlines it into the file before upload, producing a self-contained model. Select the .gltf file — the .bin is read automatically from the same folder if you are importing via a directory picker.

Model placement​

Models are placed at the origin defined inside the glTF file. For models with correct georeferencing (e.g. exported from a BIM or GIS tool with real-world coordinates), they will appear at the right location automatically.

For models without embedded coordinates, you can adjust the position by editing the layer's position style property in the Style Editor.

Performance​

  • Models with a high polygon count (> 500 000 triangles) may reduce viewer frame rate
  • Use LOD (Level of Detail) in your model where possible
  • The viewer uses Cesium's glTF renderer, which supports physically based rendering (PBR) materials, textures, and animations defined in the glTF spec
