Editing and Publishing Splats

Raw Gaussian Splat files often need editing and optimization before they're ready for production use — removing unwanted elements, compressing file sizes, and tuning the viewing experience. PlayCanvas provides two complementary toolsets:

  • The SuperSplat platform — visual, browser-based, hosted at superspl.at. The end-to-end home for editing, publishing, managing, curating, sharing, and discovering splats.
  • The splat-transform CLI — open-source command-line tool for scripted, reproducible conversions and batch processing.

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

The SuperSplat platform​

SuperSplat covers the whole lifecycle of a splat from raw capture to a polished, shareable scene:

  • Editor — open-source, browser-based editor for cleaning, cropping, color-adjusting, and animating splats. Publishes to superspl.at.
  • Direct Upload — skip the Editor and publish a finished splat file directly with the orange Upload Splat button on the home page.
  • Manage — your library: edit metadata, change visibility, choose downloadable + license, delete, open in Studio.
  • Studio — curate the published viewing experience: cameras, animations, annotations, post effects, skybox, collision.
  • Scene page — the public page where visitors view, share, embed, like, comment on, and (if you allow it) download your splat.
  • Explore — the public gallery of every shared splat, with sort, time, feature filters, and search.
  • Viewer — the open-source web viewer that powers scene pages, exportable as a single-file HTML or embeddable via the @playcanvas/supersplat-viewer npm package.
  • Convert — in-browser format conversion and transforms (translate / rotate / scale / filters), powered by splat-transform.

SplatTransform CLI​

The splat-transform CLI is the right choice when you need:

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

Both the Convert page and the splat-transform CLI use the same underlying library, so anything you can do interactively in Convert you can also automate from the command line.
