This adaptation by In Seconds (2026) contains material-bearing anatomical
geometry from the source skeletal, attachment, joint, muscular, cardiovascular,
lymphatic, nervous, visceral and skin collections. Text-label geometry is omitted.
The mixed-provenance Brain, Kidney and Internal ear collections and associated
brain materials are conservatively excluded from the Z-Anatomy export.
Changes: dense meshes reduced for web delivery, curves tessellated,
coordinate normalization, simple display colours, binary packing and selection.
An exploded view intentionally moves structures away from anatomical positions.

SEPARATE ORIGINAL BODYPARTS3D LAYER
Original brain and kidney geometry comes directly from BodyParts3D 4.0,

Adaptations: triangulation, coordinate registration against matching source
skeletal/renal bounds, normalization and binary packing. Registration parameters
and archive SHA256 are recorded in model.json. This is not patient-specific
clinical registration. The original-organs chunk remains separately CC BY 4.0.

ANATOMICAL REFERENCE TEXT
Plain educational sections selected from the English Wikipedia text bundled

the original article provides contributor history and scientific references.

Changes: section selection, plain-text formatting and length limiting.
Clinical/disease/treatment sections are not exported. No embedded script runs.
These are imported source passages, NOT independently clinically reviewed facts.

Additional layer download URLs and checksums are listed in model.json.
/anatomy-data/references.json lists each attributed reference download.

Binary format: gzip-decompressed little-endian arrays. For each manifest entry,
read vertices*3 Float32 positions at offset, followed by indices Uint32 triangle
indices at offset+vertices*12. Coordinates are normalized Y-up.

The separate PACK71 exercise catalogue (exercises.json), descriptions and media
are NOT relicensed under the anatomy model's Creative Commons licence.
They remain separately licensed PACK71 exercise content.

COVERAGE
3,615 selectable structures across 12 layers. The original 719-part model
remains the default view; further layers load on demand. Counts describe model
objects, not a census of all human tissues. Some meshes aggregate small parts;
microscopic structures, normal variants, detailed inner-ear anatomy and some
source-specific anatomical details remain absent. Model.json records exclusions.
Attachment surfaces exist only where the source provides them; no unverified
attachment point is inferred. 2,201 structures have attributed reference text.
Educational reference, not a certified medical atlas or diagnostic tool.
