SOG Viewer — Open Cesium 3D Gaussian Splatting Files Online
A free, browser-based viewer for Cesium SOG (.sog) 3D Gaussian Splatting files. Drop your .sog file and explore it on a 3D map — no plugins, no upload, no Cesium ion account required.
Open the SOG viewer
- Supports the .sog format used by Cesium 3D Tiles 2.0
- Files are read locally as blob URLs and never uploaded
- Rendered with spark.js + three.js for smooth WebGL performance
SOG (Sequential Organic Gaussians) is the container format Cesium adopted for streaming 3D Gaussian Splats inside 3D Tiles 2.0. This viewer lets you inspect a single .sog file immediately, without spinning up a full Cesium pipeline.
