Giraffe models are extremely lightweight. Since the platform is browser based, most complex or detailed geometry is too heavy to perform well.
Therefore, we accept uploads of GLTF or GLB files to represent 3D models.
What is a GLTF?
A GLTF file (GL Transmission Format) is an open-source, royalty-free standard for transmitting and loading 3D scenes and models, often called the "JPEG of 3D" for its efficiency.
The format combines 3D data and color mapping into one compact file. glTF minimizes the size of 3D assets, and the runtime processing needed to unpack and use them.
How to Make a GLTF
Many softwares can natively save GLTF/GLB, or they have plug ins to create them. If you're not sure if your software can create a gltf, search Google for "[[software name]] + gltf export."
If your software does not export to GLTF, it likely exports other open 3D formats. You can convert a CAD mesh like .stl or .obj into a GLTF using Blender (free) or 3D Studio Max (included in many Autodesk AEC packages).
There are also hundreds of websites that have free and paid GLTF assets that you can download. Some of our favorites are TurboSquid, SketchFab, and CG Trader.
Always check files for safety before downloading. Zipped files may contain malware or viruses. Check for familiar file extensions before unzipping.
Never download or install .exe files that you do not recognize!
Add a 3D Model to your Project
There are two ways to add a 3D model:
Annotations Tool
Adding the property
Annotations Tool
Click the annotation tool in the drawing toolbar (top center)
Select "Upload 3D model"
Click on the map to place a point
This places a point with the GLTF 3D property.
The "default" Giraffe GLTF appears.
Upload a new file by clicking change in the Files section of the properties palette.
Add the Property
Select a geometry.
Points work the best, but you can add a GLTF to any geometry.
Geometries with multiple control points will place the GLTF on the "first" point.
Click Add Property in the properties palette.
Search for "GLTF"
Click the property to add it.
The "default" Giraffe GLTF appears.
Upload a new file by clicking change in the Files section of the properties palette.
What are imported 3D models good for in Giraffe?
GLTF/GLB imports in Giraffe are not editable. They add context or graphic clarity - perhaps for a nearby building that you have an existing model of, or maybe you just want to add some entourage to your site for presentation purposes.
If you intend to edit your 3D model import, use one of the editable methods, like GeoJSON (best), or model the element natively in Giraffe.
| Use GLTF | Use Editable Import & Giraffe Geometry |
Detailed Entourage or site decoration | ✅ | ❌ |
Contextual Building Model - visuals only | ✅ | ✅ |
Solar Analysis | ❌ | ✅ |
Parametric sizing and adjustments to the model | ❌ | ✅ |
Giraffe publishes lots of 3D context and entourage to the Content Library - look there for park benches, picnic tables, awnings, trees, cars, people, and more!
