3D models can be leveraged in both the 3D and Trip Layer.

## 3D Model Settings

The 3D model can be configured to best represent your use case. 3D layers currently support the following settings:

| Field           | Description                                                                                                                                                             |
|------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| 3D Model         | An optional 3D model displayed for each moving object. Select from our library of 3D models or select **Custom**, [then point to a link containing a .glb or .glTF file.](https://docs.foursquare.com/analytics-products/docs/layers-3d#custom-3d-models) |
| Apply Color      | Apply a color of your choice or apply the trail's color to the 3D model.                                                                                                   |
| Size Scale       | Size is scaled by a factor of 2^x where x is the slider value.                                                                                                            |
| Roll Based On    | Set the model's roll (rotation on the X-axis) by choosing a field from the dataset or set it with the slider.                                                             |
| Pitch Based On   | Set the model's pitch (rotation on the Y-axis) by choosing a field from the dataset or set it with the slider.                                                            |
| Yaw Based On     | Set the model's yaw (rotation on the Z-axis) by choosing a field from the dataset or set it with the slider.                                                              |

> Note: The 3D layer does not currently accept fields for tilting and rotation, and must be adjusted via the slider.

## Available 3D Models

The following 3D models are currently available in Foursquare Studio:

| Name       | Icon                                       |
|------------|--------------------------------------------|
| Airplane   |  |
| Airliner   |  |
| VTOL       |  |
| Glider     |  |
| Helicopter |  |
| Car        |  |
| Truck      |  |
| Scooter    |  |
| [Custom](https://docs.foursquare.com/analytics-products/docs/layers-3d#custom-3d-models) |  |

## Custom 3D Models

To use your own 3D model, you can provide a link to a [glTF file](https://docs.foursquare.com/analytics-products/docs/data-formats-gltf) with either a .gltf (JSON/ASCII) or .glb (binary) extension.

If you need to render many models on the map, please consider the number of polygons of your model. A model that is too detailed (containing a high number of polygons) may result in significant slowdowns of your visualization.
