Editing Splats

Raw Gaussian Splat files often need editing and optimization before they're ready for production use. This process involves removing unwanted elements, compressing file sizes, and optimizing performance for real-time rendering in PlayCanvas.

Why Edit Gaussian Splats?​

Generated splat files typically have several issues that need addressing:

  • Floaters - Stray splats in wrong locations from reconstruction errors
  • Background noise - Unwanted environmental elements captured during scanning
  • Oversized files - Too many splats for real-time rendering
  • Poor performance - Suboptimal splat distribution affecting frame rates
  • Visual artifacts - Rendering glitches that need manual cleanup

Editing Tools Overview​

PlayCanvas provides both visual and command-line tools for editing Gaussian Splats:

SuperSplat Editor​

The SuperSplat Editor is a powerful, browser-based visual editor designed specifically for interactive splat editing. It's perfect for:

  • Manual cleanup and artistic editing
  • Removing unwanted background elements
  • Fine-tuning splat positioning and colors
  • Creating camera animations and flythroughs
  • Publishing splats to the web

splat-transform CLI​

The splat-transform CLI is a command-line tool for batch processing and automated transformations. It excels at:

  • Scripted, reproducible transformations
  • Batch processing multiple files
  • Automated filtering and optimization
  • Integration into build pipelines
  • Combining and merging splat files
