The PlayCanvas SuperSplat tool is used to edit gaussian splat PLY files.

See https://repo-sam.inria.fr/fungraph/3d-gaussian-splatting/ for more information on gaussian splats.

A live version of this tool is available at: https://playcanvas.com/super-splat

To load a gaussian splat PLY file, drag & drop it onto the application page. Alternatively click the "Choose file" button bottom left.

If you disable the "Load all PLY data" option before loading the file, then the PLY data not required by the editor is excluded (for example the spherical harmonic data). This can save on browser memory.

Once a PLY file is loaded you can use the selection tools to modify splat selection and then delete splats from the scene.

You can also reorient the scene using the SCENE Position/Rotation/Scale controls.

Once you're done editing the scene, click the Export -> "Ply file" button to export the edited splat scene to the local file system.

This editor is in beta and so currently has a number of limitations:

• Only supports gaussian splat PLY files
• Spherical harmonic data is not rotated on export

The steps required to clone the repo and run a local development server are as follows:

git clone https://github.com/playcanvas/super-splat.git
cd super-splat
npm i
npm run develop

The last command npm run develop will build and run a local version of the editor on port 3000. Changes to the source are detected and the editor is automatically rebuilt.

To access the local editor instance, open a browser tab and navigate to http://localhost:3000.
