3D Gaussian Splatting is a recent volume rendering method useful to capture real-life data into a 3D space and render them in real-time. The end results are similar to those from Radiance Field methods (NeRFs), but it’s quicker to set up, renders faster, and delivers the same or better quality.

Plus, it’s simpler to grasp and modify. The result of the method can be called Splats.

Create a Gaussian splatting by using a mobile app like Polycam or Luma:

That’s it! Now you can start adjusting how the splats look in your Spline scene.

Apply Cropping
When using crop areas, Spline only exports the visible splats within these areas to increase performance in your final exported scene.

If you also want to permanently apply your crop areas in-editor, you can press "Apply Cropping". This will permanently delete the invisible splats outside the cropping area, which can increase performance within the editor itself.

You can use crop areas to remove parts from your splats. This can be useful for optimization/performance but also for aesthetic reasons.

Note: Support for the splats within the Performance panel will be added soon.

Note: Mobile support is partial. This is still an experimental feature (recent technology) and mobile support is an ongoing effort.

Gaussian splats are rendered in a different way than normal objects or geometries, this means that not all of the features are directly compatible when mixing them together.
Currently, the following features are either not compatible or partially supported with Splats:

Don’t be discouraged by the limited support!
Until recently, it was almost impossible to render real-time hyperrealistic 3d representations like this on the web. The technology is evolving fast, and improvements will come over time!

Keep an eye on Spline’s updates!
