Transfer from original 3DGS PLY

[hwfan]

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.

[stytim]

I made a simple converter for Windows, which can be built with CMake, Visual Studio: https://github.com/stytim/spz. A pre-built executable is also provided. Feel free to check it out.

Folks from the Niantic team like @nbutko, are you interested in merging PR from the above @stytim implementation upstream for an official converter CLI?

For folks looking for the same feature-set, a JS CLI from playcanvas is available here with limited format support atm - discussion tracking additional integrations here playcanvas/splat-transform#1
