Filtering Gaussian Splats đź«ź
Published on October 21, 2025 by Kirill Vasin
We’ve been tinkering with Gaussian-splats for a while, and today we’re releasing our small, but useful tool SplatMesh — a Wolfram Language paclet for rendering (with spark.js), and basic editing splats right inside your WLJS or Mathematica notebook workflow.
⚠️ Accurate rendering is not possible in Mathematica, but only preview as point clouds
TL;DR
In this short post I’ll walk through:
- import a noisy Scaniverse capture,
- define a cylindrical region of interest,
- filter splats with a single predicate (functions receive [index, center, scales, quaternion, opacity, color]),
- preview as 3D points (Mathematica-friendly ✨),
- and export the result.
