Great work! Will it be possible to transfer from original 3DGS PLY?

A CLI based converter (from/to spz) or python lib wrapper would indeed be useful to people outside the Niantic/Scaniverse ecosystem + to make that standard diffuse within the gsplat community.

Then, developing writers, readers and parsers within existing viewers libs and engines (gsplat trainers, web/js viewers, 3D engines etc) would make it also easier for companies to eventually adopt spz against other compression-based standards.

We made one such converter for macOS. You can check out our fork and the swift branch. You will need Xcode to build the CLI. I have only tested the result with the Niantic Creator tool since it’s the only one so far that supports this format.
