SPZ to SOG Converter

If you have scanned real-world spaces with Scaniverse on your mobile phone and want to embed them on the web or clean them up in the SuperSplat Editor, converting from .spz to .sog is the recommended path.

SOG arranges the splats in Morton spatial order and encodes them into GPU-ready WebP texture maps, enabling instant streaming without decoding delays.
