A Faster SuperSplat with PWA Support

ยท 2 min read

Today, we are announcing the latest release of SuperSplat, the open source tool for editing and optimizing 3D Gaussian Splats. If you don't have a PLY file to hand, here's an example!

SuperSplat PWA

Version 0.17.1 focuses on two key areas: performance and PWA support.

Performance Improvementsโ€‹

SuperSplat is now over 2x faster on the GPU! ๐Ÿƒ

Compare before and after (notice GPU time dropping from 32ms to 13.5ms for the bike scene):

This is thanks to the v1.71.0 release of the PlayCanvas Engine, which includes a dramatic overhaul of how splats are processed by the GPU. For the technical details, take a look at this pull request.

The result is that SuperSplat can now throw around millions of splats and still maintain a silky smooth frame rate. Try it for yourself!

PWA Supportโ€‹

A Progressive Web App (PWA) is a web application that provides a native app-like experience, including the ability to install it on a user's home screen or desktop.

From today, SuperSplat is shipping with PWA support! ๐ŸŽ‰

To install SuperSplat as a PWA:

  1. Visit
  2. Hit the Install SuperSplat button in the address bar.

For your convenience, pin SuperSplat to the Taskbar (Windows) or add it do the Dock (macOS).

PLY File Associationโ€‹

With SuperSplat installed as a PWA, your operating system can now open launch PLY files directly into the tool. Simply right-click on a PLY file and select SuperSplat to open it.

You can also set SuperSplat as the default tool to open your PLYs. Then, you can simply double-click a PLY file to open it instantly in SuperSplat!
