On August 7, 2025, Khronos Group, OGC, Niantic Spatial, Cesium (Bentley) and Esri announced work to integrate 3D Gaussian Splats into the glTF format by developing two extensions to standardize storage and SPZ compression for photorealistic radiance-field point primitives. The initiative adopts Niantic’s open-source SPZ (claiming up to 90% compression versus PLY), updates SPZ v2.0.0 with improved quaternion rotation encoding, and aims to improve geospatial interoperability and streaming across platforms.
