title: Gaussian Splats
template: doc

[Gaussian splatting](https://www.youtube.com/watch?v=HVv_IQKlafQ) is a technique for creating photorealistic 3D scenes by using millions of semi-transparent, 3D ellipses (gaussians).

Gaussian splats are generated by "training" from the images + camera poses + sparse points of a photogrammetry scene.

WebODM supports the generation of gaussian splatting scenes via [OpenSplat](https://github.com/WebODM/OpenSplat) and other [software](#software). Subsequently a splats model can be displayed in WebODM alongside point clouds and textured models.


:::note

Gaussian splatting requires oblique and/or orbit shots in order to generate good results. You must capture the details of a scene from multiple viewpoints. A nadir-only flight, usually yields very poor results.

:::

### Workflow

1. Process a RGB dataset with WebODM
2. Click **...** next to a task and select **Splats**
3. Download the training data file (.zip)
4. Process the splats using one of the [software](#software) below.
5. Upload the resulting splat model to WebODM.

:::tip

If supported, export scenes to .RAD format. It will save time during upload. Every splats model gets converted to .RAD in WebODM anyway.

:::

### Software

This is a list of free and open source software that we tested, but others might work too.
