Edit a 3D Gaussian Splatting Model in SuperSplat

After training and exporting the .ply file, you can open the model in SuperSplat Editor for visual inspection and manual refinement.

Common editing tasks include:

  • Removing floating artifacts or unwanted background Gaussians
  • Cropping the model to a region of interest
  • Adjusting appearance settings (brightness, saturation, temperature, transparency)
  • Applying transformations (scaling, centering, orientation correction)
  • Merging multiple models into one scene
  • Exporting a cleaned version for presentation or further use

For a complete list of tools and options, see the SuperSplat documentation.

Load a model into SuperSplat

  1. Open the editor: https://superspl.at/editor
  2. Drag and drop your .ply file (for example, point_cloud_29999.ply) onto the canvas
  3. Alternatively, go to File → Import… and select the file manually

Model loaded in SuperSplat Editor.

The model will appear as a dense cluster of Gaussians, typically surrounded by floating artifacts.

Clean the model in SuperSplat

Documentation for editing tools is available in the SuperSplat Editing Guide.

The following workflow shows a common sequence for model cleanup. You can adjust it based on your dataset and editing preferences.

1. Remove floating artifacts using Sphere + Invert

  • Use the Sphere Selection tool to enclose the main object (for example, the toy)
  • Go to Select → Invert to select everything outside that region
  • Press Delete to remove the surrounding Gaussians

Removing outer Gaussians using sphere selection and inversion.

2. Refine with Brush or Lasso

  • Use the Brush, Lasso, or Polygon tools to clean up remaining floating points around the object.

  • These tools are useful for fine-tuning areas around edges or details of the object

Cleaning additional areas using brush selection.

3. Final cleanup using the Picker tool

  • Use the Picker tool to select individual Gaussians precisely
  • Enable Splat View Mode to visualize Gaussians as ellipses
  • This helps identify large or misaligned Gaussians that often represent noise

Picker tool and Splat View Mode enabled for final cleanup.

Export the cleaned model

Once editing is complete:

  1. Go to File → Export… in the SuperSplat interface
  2. Choose one of the available formats:
    • A standard .ply file
    • A compressed .ply file that reduces file size without sacrificing quality

The exported model can be used for:

  • Presentations
  • Downstream rendering
  • Integration into 3D graphics pipelines
