Editing and Cleaning 3D Gaussian Splats: Practical Workflows and Software
Raw photogrammetry splats suffer from floating artifacts and background noise. Learn how to crop, transform, and optimize 3DGS point clouds for production engines.
While initial 3D Gaussian Splatting training creates hyper-realistic scenes, raw output files often contain floating noise particles (floaters) and unwanted background geometry that degrade real-time performance.
1. Browser-Based Editing: PlayCanvas SuperSplat Pipeline
Tools like SuperSplat allow instant web-based manipulation of .ply files. Bounding box selections, spherical clipping zones, and isolated point deletes trim unnecessary Gaussians without re-training models.
2. Integrating 3DGS Clean-Up into Blender Add-ons
Using specialized Blender plugins (e.g., K-Splat or Brush extensions), technical artists can leverage standard viewport selection tools to trim floating artifacts, re-center origin points, and align splats with traditional polygon props.
3. Gaussian Pruning and Spherical Harmonics Reduction
Optimize final file size for web delivery by stripping higher-order Spherical Harmonics (SH) coefficients and pruning low-opacity Gaussians, reducing total memory footprints by over 60% with minimal visual loss.
