SOG lightweight containers vs PLY trade-offs

SOG favors small payloads and fast first paint but trades geometric/texture fidelity; keep PLY/splat masters for archival handoff.

Cross-checked against public sources

Role

SOG targets fast web preview—not a sole archival format or lossless review master.

Pros and cons

Pros: smaller payloads and faster IO. Cons: lossy detail loss and non-reversible recovery to full PLY quality—keep lossless masters.

Toolchain hooks

Freeze a master before SOG conversion; validate lighting/opacity in target viewers; compare SOG vs SPZ/splat via splat-transform and the SPZ reference impl.
