request: Docs for SOGS

[Strepto]

Hi, great project! The new Self Organizing Gaussian Splats (SOGS) implementation looks very exciting.

Would you mind documenting how to use it? Maybe this file is correct? https://github.com/sparkjsdev/spark/blob/main/docs/docs/loading-splats.md

[dmarcos]

Thanks. Yes, we need to document

@dmarcos Any more developments for this? Or any documentation or examples using sogs? If I try to load a sog file, it gives me an error that it is an unrecognised file type, and I cannot find any documentation on how to fix it.

@Strepto did you manage to get it working?

I believe you can upload a .zip file with the sogs output.

Convert the ply or similar to sogs with a sogs converter. I used: https://github.com/playcanvas/splat-transform with these params.

# splat-transform v0.5.0
splat-transform "my.ply" "./output/meta.json"

# Compress with powershell, but could be any standard .zip.
Compress-Archive -Path ./output -DestinationPath "my.zip"

Then i .zipped the output folder and its usable by the sparkjs viewer: https://sparkjs.dev/viewer/

Remark: I see that the splat-transform package has added support for a "SOG v2" format, which I am not sure if is supported in sparkjs yet? playcanvas/splat-transform#38 EDIT: SOG v2 is supported! #179

As the SOG v2 format is supported I tested that as well:

# splat-transform v0.13.1
splat-transform "input.ply" "output.sog"

No zip needed, just drag and drop the .sog file to the sparkjs viewer

Do note that the latest Spark release (0.1.9) only supports SOGS v1. Support for SOG (aka SOGS v2) has been merged into the main branch (#179), but hasn't been part of a release yet. The hosted sparkjs viewer already runs the latest version, hence it loading .sog files without issue.

If you want to use .sog files in a project, either use the main branch or wait for the next release.

Excited for the next release!

Any ETA for the release containing SOGS v2 support?

For the record: SOGS v2 (.sog files) support was released in v0.1.10 🎉
