3D Gaussian Splatting (3DGS)

About

3D Gaussian Splatting, or 3DGS is a technique that renders high fidelity objects and scenes using lots of tiny translucent ellipsoids or "splats." Each splat carries information about its color, size, position, and opacity.

This allows for great levels of detail and photorealism in real-time rendering.

Working with Gaussian Splats

3DGS is a nascent technique for which new tools and uses are continually being developed. In addition to the 404—GEN Unity Add-on and Blender Extension, here are a few other tools and plug-ins for 3DGS.

Spline

3D design software with 3DGS support, detailed in their docs.

SuperSplat

Open-source, browser based viewer and editor for Gaussian Splats, by PlayCanvas

Unreal Engine

Native support is not yet available for this game engine, however XVerse offers a free 3DGS plug-in for Windows 10 and 11 users.

Explore the multitude of 3DGS developments and applications on the GitHub Topics for Gaussian Splatting.

For a highly technical explanation, the study 3D Gaussian Splatting for Real-Time Radiance Field Rendering led much of the recent research and experimentation with 3DGS.
