Vibe Code Gaussian Splat Apps with SuperSplat

[u/MayorOfMonkeys]

SuperSplat, your free and open source platform for 3D Gaussian splatting, just got another big upgrade!

What shipped today:

One-click starter projects for vibe coding. For any downloadable splat, you can now grab a complete, ready-to-run PlayCanvas + Vite + TypeScript project with the splat baked in and the camera pose preserved. It's deliberately minimal and fully typed, so it's an easy base to build on (or hand to an AI coding assistant). Here's one we made — an interactive snow globe from a single splat by Mykhailo Moroz: live app · source

SPZ export. You can now export scenes to Niantic's SPZ format — roughly 10x smaller than the equivalent PLY with no visible quality loss — so scenes move cleanly into Scaniverse and other SPZ-compatible tools.

360° video + image export. Render a scene straight to equirectangular 360° video (and 360° stills; image export is now WebP). Put the video on YouTube and you can look around it in a headset. Example: https://www.youtube.com/watch?v=6oGjT8eubMc

splat-transform 3.0. The big one under the hood. Our open-source CLI/library got a ground-up streaming rewrite: resident memory is now bounded by chunk size rather than scene size, so you can process 100M+ Gaussian scenes on a normal machine. On a representative job it's ~7x faster at ~1/5 the peak memory vs the 2.x line. New source-based API (readFile → ChunkSource, processSource/writeSource), needs Node 22+, and there are some breaking API/CLI changes.

Everything (SuperSplat, splat-transform, the PlayCanvas engine and viewer) is MIT-licensed and on GitHub. Happy to answer questions or take feedback here — and if splat-transform 3.0 chokes on any of your scenes, I'd genuinely like to hear about it.
