Crate oxihuman_morph 

Morphology engine for parametric human body generation.

Provides target-based morphing, blendshape interpolation, age and body composition models, FACS facial expressions, pose graphs, and GPU-ready skin deformation — all in pure Rust.

Module Organisation

The public API is split across six internal sub-modules to keep individual source files manageable. All items are re-exported at the crate root so callers import everything directly from oxihuman_morph::.

Part	Approx. content
_morph_part1	Core engine, animation, basic morphing
_morph_part2	Facial rigs, pose systems, body scan
_morph_part3	Fine facial controls (brow/cheek/chin/ear)
_morph_part4	Fine facial controls (eye/face/body segments)
_morph_part5	Morph targets, skinning, ML morphs
_morph_part6	Skeletal morphs, body-shape archetypes, anatomy
