GaussianSplats3D

GaussianSplats3D is a Three.js-based renderer for 3D Gaussian Splatting that can load PLY, SPLAT, and KSPLAT scenes in browser-based experiences.

What It Does

GaussianSplats3D helped make splat rendering approachable for Three.js developers. It includes a built-in viewer, npm package, conversion to KSPLAT, optimization features, and WebXR support.

For new production work, compare it with Spark.js. For existing projects or KSPLAT-based examples, it remains an important reference.

How To Use It In 3DGS

Install the npm package or build from the GitHub repository.
Create a viewer and call addSplatScene with a PLY, SPLAT, or KSPLAT file.
Tune viewer parameters such as alpha thresholds, sort behavior, and scene transforms.
Profile sorting and memory when loading large scenes or multiple assets.

Things To Watch

The repository notes it is no longer in active development.
Transparent mesh integration and depth behavior can require care.
For long-term active development, evaluate Spark.js alongside it.

Legacy Value

GaussianSplats3D remains useful for understanding KSPLAT, WebXR support, splat sorting, octree culling, and built-in viewer ergonomics in a Three.js setting.
The maintainer explicitly recommends Spark for active new development, so treat this as a stable reference or compatibility tool rather than the default future bet.
If you inherit a KSPLAT scene or older Three.js demo, this project is often the fastest way to understand how it was intended to load.
