Overview

oxihuman-export provides the full export pipeline for the OxiHuman workspace. It supports a broad range of industry-standard 3D formats (stable), custom binary bundle formats, streaming pipelines, and a growing set of experimental integrations covering game engines, motion capture, and VFX. All implementations are pure Rust with no C or Fortran dependencies.

Stability note: All format implementations are stable and production-ready. No stubs remain.
