What is a .SPZ file?
SPZ is a compact format for 3D Gaussian splat scenes. Created by Niantic.
- Did you know
- Niantic released SPZ in 2024 to make Gaussian splat scenes far smaller to store and share.
- The name stands for “Splat Zip”, and SPZ was built for Niantic’s Scaniverse scanning app and released under the MIT licence.
- An SPZ is roughly ten times smaller than the equivalent PLY while keeping the splats’ full spherical-harmonic colour.
- What Analyser reads
- Header and metadata extraction for 3D meshes, voxels, BIM, point clouds and Gaussian splats: Wavefront OBJ, Stanford PLY, OFF, glTF, AMF, MagicaVoxel VOX, COLLADA DAE/ZAE, USD crate, X3D/VRML, LightWave LWO/LWS, Quake MD2/MD3/MDL, VRM avatars, Siemens JT, LAS/LAZ/PCD/PTS/E57 LiDAR clouds, IFC BIM, and .splat/.spz - vertex/face/point counts, bounding boxes, units and authoring tool.
- Depth of analysis
- .SPZ is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .SPZ file
- Drag a .SPZ file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
