DETAILED MODEL REVISION (2026-10-12)

License: Creative Commons Attribution-ShareAlike 4.0 International; retain BodyParts3D attribution.
Converted with assimpjs / Assimp, compressed with Draco, 16-bit position quantization.
Original named structure hierarchy preserved in GLB. Non-muscular fasciae/bursae are omitted from the default viewer.
Mirrored triangle orientation corrected during flattening; no anatomical shape resculpting performed.
Display muscle microtexture is procedural and illustrative, not cadaver photography or histology.
Selection keeps the original display material without yellow recoloring.
Adapted assets and original licenses remain freely downloadable:

Skeleton display asset excludes annotation pointers and painted origin/insertion patches; anatomical bone, tooth, cartilage and suture surfaces retained without simplification.

ATLAS SYSTEM EXPANSION (2026-10-12)
Additional source files from LluisV/Z-Anatomy, PC-Version/Resources/Models/FBX:
VisceralSystem100.fbx, NervousSystem100.fbx, CardioVascular41.fbx.
Same Z-Anatomy CC BY-SA 4.0 / underlying BodyParts3D attribution as above.
Converted with Assimp; removed editor annotation material; pruned unused data;
compressed with Draco, 16-bit positions. Heart asset retains heart and selected
major vessels from the cardiovascular source, not the complete vascular tree.
Display colors and muscle surface texture are illustrative. No copied Astra code
or extracted Astra assets are included. Independently implemented atlas controls.

SURFACE AND VASCULAR REVISION (2026-10-12)
Source also includes Joints100.fbx and the arterial/venous surfaces of
CardioVascular41.fbx from the same Z-Anatomy repository and licenses.
Shared identical positions welded and per-surface vertex normals recomputed.
This changes lighting interpolation, not the anatomical vertex positions,
triangle connectivity, source hierarchy or dimensions. UV muscle detail is
illustrative. Source material boundaries are retained. No commercial medical
atlas assets or code have been copied from the reference images or Astra.
Hemibody muscle clipping and a heart clipping plane are display tools; they
are not a surgical reconstruction. Arteries, veins and cartilage use study colors.

SPANISH NOMENCLATURE AND TEGUMENTARY SURFACES (2026-10-12)
Spanish names adapted from LluisV/Z-Anatomy Resources/Translations0.txt,
with AlcoCerMed orthographic corrections and missing-name translations.
Same CC BY-SA 4.0 attribution and underlying BodyParts3D license apply.
Skin/nail surfaces: Resources/Models/FBX/Regions of human body100.fbx.
Skin and nail materials retained; annotation geometry excluded. Welded normals,
Draco 16-bit positions and illustrative skin color; no resculpted anatomy.
The 3D layer displays external skin regions and nails, not histological layers,
hair follicles or gland anatomy. Educational skin descriptions: Saladin chapter 6.

SOURCE HIERARCHY ALIGNMENT RESTORATION (2026-10-12)
Some empty FBX grouping nodes lose their transforms during Assimp conversion.
Restored their authored local position/rotation/scale from the original source:
https://github.com/LluisV/Z-Anatomy/blob/PC-Version/Z-Anatomy%20PC/Assets/Prefabs/%40Human%20Body.prefab
Converted Unity local coordinates to the corresponding FBX/GLB coordinates.
Existing nonidentity FBX transforms and all mesh vertex coordinates retained.
This includes the Sternum.g hierarchy shared by the manubrium and sternal body.
No arbitrary snapping, per-camera repositioning or resculpted attachment points.
Source transforms distributed under the same Z-Anatomy CC BY-SA 4.0 terms:
https://www.alcocermed.com/anatomia-alineacion.js

LYMPHATIC MODEL (2026-10-12)
Z-Anatomy / LluisV PC-Version, Resources/Models/FBX/LymphoidOrgans100.fbx.
Same CC BY-SA 4.0 attribution above. Source annotation geometry removed; source coordinates retained, missing group transforms restored from original prefab. Smoothed shared vertices and Draco-compressed.
https://www.alcocermed.com/assets/anatomy/linfatico-detallado.glb
Organ neurovascular/lymphatic summaries: user-provided Saladin and anatomical references linked on each card. Small vessels and terminal autonomic plexuses are not fabricated.

GLUTEAL EDUCATIONAL EXTENSION (2026-10-12)
Inferior gluteal nerve is absent from the original NervousSystem100 mesh and Unity prefab. AlcoCerMed added bilateral schematic 3D curves with terminal branches following the original deep gluteus maximus surface. These are educational reconstructions, not segmented source anatomy, and do not represent rootlets, exact branching or individual variations. Original arteries were retained without alteration.

ATLAS STUDY AND MOTION REVISION (2026-10-12)
Recognition objectives and skeletal notes synthesized from the user-supplied Saladin, chapters 8–9, 10, 13–14 and 19–25. Guided views preserve the original coordinates and anatomical alignment.
Respiratory expansion, atrial/ventricular contraction and oesophageal/ureteric peristalsis are explicitly schematic educational motion, not a biomechanical or patient-specific simulation. Source geometry is restored on pause; major cardiac vessels do not contract with the chambers. Joint rigs, autonomic plexuses and microscopic networks absent from the source are not claimed as completed anatomy.
Cosmetic organ surface variation is not a histological image, lesion map or vessel map. Original source models and attribution above remain unchanged.
Revision 15: sensory catalog exposes existing original eye, auditory ossicle,
tympanic membrane, cochlea, vestibular labyrinth, olfactory nerve and tongue
meshes. No new microscopic receptor geometry is claimed. Study descriptions
are original summaries of the supplied Saladin, chapter 16. Transparent optical
media are illustrative display materials, not an optical simulation.

Revision 21: bone landmark coordinates derive from the original Z-Anatomy annotation arrows and Spanish nomenclature. They are anchored to their owning original bone surface and projected onto the matching displayed bone. Contralateral copies are checked against the corresponding source surface. Coordinates and Spanish labels in anatomia-huesos-relieves.js are a CC BY-SA 4.0 derivative of Z-Anatomy.
Bone study cues paraphrase the supplied Saladin, chapter 8. Variation and development notes do not claim additional variant 3D meshes.
