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

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

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

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

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

Reference versions from the sample dataset are available in the repository:

• Cleaned model
• Cleaned and compressed model
