Both PlayCanvas SOG and Niantic SPZ are state-of-the-art compression formats for 3D Gaussian Splats, but they serve different parts of the 3D ecosystem: SOG is optimized for WebGPU streaming, while SPZ is the universal standard for mobile AR in Scaniverse and Babylon.js.
Converting SOG to SPZ bridges these two leading platforms, allowing web-captured or SuperSplat-edited assets to be opened smoothly in Niantic mobile apps.
