MODEL ADAPTATIONS
- Selected 233 oral and adjacent structures from seven anatomy systems:
  skeletal, visceral, muscular, nervous, cardiovascular, lymphatic and joints.
  Fourteen named nerve branches were later separated from six of them and four
  named artery branches from two, giving 251 named structures; ten more
  structures were later added from the same source (below), giving 261; four
  palate muscles were then added from BodyParts3D 4.0 (below), giving 265.
- Combined them in one glTF 2.0 GLB; omitted unselected structures. The current
  21,876,824-byte GLB uses lossless EXT_meshopt_compression and requires a
  compatible viewer/importer. No quantization or lossy filter was used. Decoded
  floating-point attributes and triangle winding were verified unchanged.
- Applied the original Z-Anatomy Blender author's render-subdivision settings to
  17 structures. This refines smoothness without adding measured microanatomy.
- Registered 18 higher-resolution published BodyParts3D 3.0_95 whole-tooth
  surfaces to their corresponding atlas teeth, using one rotation, uniform
  scale and translation per tooth, with no nonrigid warping or new sculpting.
  Their triangle total increases from 28,520 to 137,716. Left counterparts use
  bilateral reflection matching the existing Z-Anatomy construction.
- Later registered the BodyParts3D 3.0_95 surface FMA55705 to the outer crown
  and root surface (1,836 triangles) of both lower first molars in the same
  way (uniform scale 1.0311; RMS 0.017 mm, sampled maximum 0.097 mm) and
  replaced only that surface: the original Dentine surface and inner enamel
  shell are kept unchanged inside it. With these, 20 registered teeth total
  155,352 triangles (32,192 before).
- Preserved the original meshes of the 8 teeth not replaced and the tongue
  (343 vertices / 682 triangles); they do not pass the registration gate
  against BodyParts3D, which has no tongue or third molars in version 3.0. The four trigeminal nerve roots
  retain their prior geometry in the later surface refinement.
- Transferred source-atlas crown/root material roles to upgraded teeth by
  nearest-surface correspondence. These visual material regions do not establish
  separately measured enamel, dentin, cementum, pulp or periodontal layers.
- Retained English anatomical identities (za_name), existing anatomical
  placement, and source material roles, except for the one side correction
  below; supplied independently written Korean labels, short descriptions,
  category identifiers, detail-source metadata and measured bounds. Original
  structure-definition prose was not reused.
- Corrected one side labelling inherited from the source. The atlas frame has
  +x toward the patient's left, and every other paired structure lies on its
  named side, but the lateral temporomandibular ligament named .l lay on the
  patient's right (bounds centre x about -53.2 mm, touching the mandible and
  right-side structures only) and the one named .r on the left. The two named
  GLB nodes exchanged their placement (translation, mirroring and mesh
  reference), so each ligament now carries the name, Korean label and
  description of the side it lies on. Mesh data and every primitive are
  byte-identical; bounds and nearby lists were updated. npm run check now
  fails if any .l structure lies at x <= 0 or any .r at x >= 0.
- The surface update refines 100 structure geometries: 80 native source curves
  (26 nerves, 36 arteries and 18 veins) and 20 lymphatic/tonsillar structures.
  Curve control points, handles, radii, branches and world transforms remain
  unchanged. Lymphatic surfaces receive two Catmull-Clark subdivision levels.
- In that surface update, 132 structure geometries were unchanged, including
  all 28 teeth and the four trigeminal nerve roots. Tissue materials and UV
  texture coordinates were supplied for 104 structures, including those four
  roots without geometry changes.
- Added the original Z-Anatomy sphenoid bone (3,650 vertices / 7,308
  triangles) with bone and suture material roles. A higher-resolution
  BodyParts3D 3.0 FMA52736 surface was registered with one rotation, uniform
  scale and translation but not used: against the Z-Anatomy surface its RMS
  was 0.73 mm, 95th percentile 1.37 mm and maximum 7.6 mm, beyond the dental
  registration gate.
- Separated 14 named nerve branches (seven per side) from the existing
  maxillary, inferior alveolar and facial nerve spline surfaces: infraorbital
  nerve, incisive nerve, and the temporal, zygomatic, buccal, marginal
  mandibular and cervical branches of the facial nerve. Every original
  triangle is kept exactly once; flat caps close the cut ends where the
  maxillary and facial nerve trunks are divided. The source splines are
  unnamed, so these branch identities are an interpretation of their course
  (described in DETAILS.html), not separately sourced anatomy. All other
  structure geometries are unchanged.
- Separated 4 named artery branches (two per side) from the maxillary artery
  by moving whole unnamed source splines: the middle superior alveolar artery
  (the spline leaving the infraorbital artery in its groove, with its twigs)
  and the dental branches of the posterior superior alveolar artery (the
  spline descending over the maxillary tuberosity, with its twigs). No spline
  was cut and every original triangle is kept exactly once; the names are an
  interpretation of the splines' course.
- Added 10 structures from the same Z-Anatomy Blender file after a
  registration check: frontalis, the orbital and palpebral parts of
  orbicularis oculi, platysma and the vagus nerve (X), each on both sides.
  Eight reference structures read from that file coincide with the GLB within
  0.006 mm after the fixed axis conversion, so no fitting was applied. Each
  muscle is a closed surface with at most 0.1% lying more than 0.5 mm inside
  bone, no more than the existing facial muscles (up to 3.0%). Frontalis and
  platysma are clipped at the atlas region box and capped, so the model bounds
  and centre are unchanged. The vagus nerve uses the atlas nerve-curve
  construction; its trunk is cut where it leaves the atlas region. Every
  earlier primitive is byte-identical. Styloglossus and palatoglossus have no
  source mesh; they are drawn only as schematic paths (below).
- Added levator and tensor veli palatini, both sides, from BodyParts3D 4.0
  (simplified copy above). BodyParts3D 4.0 is not in the atlas frame, so one
  similarity transform (scale 0.9831, 0.34 degrees of rotation beyond the
  fixed axis conversion) was fitted jointly on nine neighbouring structures
  (sphenoid, maxillae, temporal bones, palatopharyngeus, superior pharyngeal
  constrictors), which then lie within a median 0.24-0.49 mm of the atlas
  surfaces (RMS at most 1.23 mm). Each muscle is a closed surface with 0-2.2%
  lying more than 0.5 mm inside bone (existing nearby muscles: 0-4.2%). Model
  bounds and centre are unchanged and every earlier primitive is
  byte-identical. Korean labels and descriptions are original.
- Current model: 265 named structures, 922,089 vertices and 1,723,532
  triangles.
- Nearby-structure lists store closest-surface distances and approximate
  contact areas computed from this geometry. They are not clinical
  measurements.
- An optional schematic layer (src/schematic-data.json, generated by
  tools/schematic/derive.mjs) draws structures the source does not model:
  the superior alveolar, palatine and nasopalatine nerves, the lingual and
  sublingual arteries and the maxillary sinus. The paths follow landmarks of
  this adapted model (companion arteries, nerve trunks, root apices and bone
  surfaces). They are illustrative, are not measured anatomy, and are not part
  of the GLB or the structure count.
- The viewer changes display colors, illumination, gloss, opacity and clipping.
  Browse structures translates complete structures into ten category boards
  with adjacent left/right pairs, preserving each structure's scale and shape.
  These runtime display changes do not alter the downloadable GLB; Anatomy
  restores the assembled anatomical placement. The bilingual viewer and
  documentation provide English/Korean presentation without changing the
  original source names or third-party notices.
- Display shading is not a claim of photoreal tissue color, microscopic surface
  measurement or patient-specific clinical accuracy.

TRUNK AND LIMB PAGES (WEBSITE)
Whole male body (pelvis-male.glb): read directly from the original
Z-Anatomy Startup.blend (Blender 3.5, SHA-256 9f08a17ea0115fed80b2a73ecdf0a1bc2ab2f6956f37c593ce23d513ea35afcd),
the same file and fixed axis conversion as the head model, not from the nqwrc
distribution. It contains no Z-Anatomy kidney, inner-ear or brain component
(see SCOPE OF UPSTREAM LICENSE NOTICES); its brain is from BodyParts3D 4.0
(below). Changes:
- Selected 2,486 structures of the whole body in a region box (x -340 to
  340 mm, y 0 to 1,720 mm, z -140 to 145 mm), none of them cut: the head
  (skull bones, ear ossicles, paranasal sinuses and ethmoidal cells, nasal
  cartilages and mucosa, nasopharynx, 28 teeth, jaw joints and ligaments,
  facial, scalp, masticatory, tongue and extraocular muscles, tarsal plates,
  temporal and masseteric fasciae, pituitary, eyes and lacrimal apparatus,
  tympanic membrane and auditory tube, tongue, gingiva, soft palate, parotid
  and sublingual glands and ducts, cranial nerves I-VIII with the trigeminal
  branches, cerebral, ophthalmic, maxillary and facial arteries, dural venous
  sinuses and facial veins, facial lymph nodes and palatine tonsils), the
  neck (hyoid, cervical vertebrae, larynx with its cartilages, membranes and
  muscles, pharyngeal constrictors, oropharynx and laryngopharynx, thyroid and
  submandibular glands, platysma, sternocleidomastoid, suprahyoid,
  infrahyoid, scalene, prevertebral, suboccipital and deep back muscles,
  investing cervical fascia, carotid, vertebral, facial and jugular vessels,
  glossopharyngeal, vagus, accessory and hypoglossal nerves, cervical nodes),
  the thorax
  (ribs, costal cartilages, sternum, thoracic vertebrae and their joints and
  ligaments, intercostal muscles, diaphragm, heart with chambers, valves and
  papillary muscles, lungs in lobes, pleura, trachea and bronchi, great,
  coronary and pulmonary vessels, thymus, oesophagus, vagus nerves,
  sympathetic trunks, lymph nodes), the pectoral girdle and both upper limbs
  (clavicles, scapulae, humerus, radius, ulna and the bones of the hand; the
  shoulder, elbow, radio-ulnar, wrist and hand joints with their capsules,
  ligaments, bursae and tendon sheaths; pectoral, shoulder, upper back, arm,
  forearm and hand muscles, fasciae and retinacula; axillary, brachial,
  radial, ulnar, palmar and digital vessels; the brachial plexus with its
  nerves to the fingers; axillary and cubital nodes), the abdomen (stomach,
  duodenum, liver,
  gallbladder, bile duct, pancreas, spleen, suprarenal glands, omenta, colon,
  abdominal-wall and back muscles, abdominal vessels and nodes), the pelvis
  and both lower limbs (bones, joints, ligaments, menisci, bursae, tendon
  sheaths, muscles, tendons, fasciae, retinacula, vessels, nerves and lymph
  nodes); 1,549 original meshes and 937 Bezier curves (vessels, nerves, ducts,
  bronchi, small intestine).
- Left out for their licences: the Z-Anatomy brain (cortex, white matter, basal
  ganglia, diencephalon, brainstem, cerebellum, ventricles, cranial-nerve
  nuclei, falx, tentorium and pineal gland) - the model notice lists the
  "Brainder" and "White matter" models among its sources with no licence and
  does not mark which brain objects came from them, so no brain object is
  used - and the cochlea, vestibule and the cochlear nerve mesh, adapted from
  "Anatomy of the Inner Ear - by University of Dundee School of Medicine -
  CC-BY-NC-SA 4.0". The cranial nerves are Z-Anatomy curves; the notice also
  credits "Cranial Nerves and Foramina - by University of Dundee, CAHID -
  CC-BY 4.0", whose adaptation into CC BY-SA is permitted with this credit.
- Left out: the kidneys, renal pelves and intrarenal arteries and veins
  (Z-Anatomy adapted its kidney from "Kidney - by Lissie Cowley - CC-BY-NC
  4.0", which cannot be offered under CC BY-SA 4.0; the renal arteries and
  veins therefore end at the hilum); the eight Couinaud segments of the liver,
  which overlap the whole-liver surface by 1-3 mm; the schematic spinal-cord
  cross-section and its path curve; the parathyroid glands (flat nine-vertex
  placeholders, 0.15-0.25 mm thick); in the head the zonular fibres (two
  faces), two unnamed septal arterial curves, the eyeball's drawing helpers
  (equator, meridians, ciliary-body and zonular curves) and the medullary
  path curve; objects without usable
  faces (the zona orbicularis, conoid ligament, thoracic intertransverse
  ligaments, the articular discs of the sternoclavicular and
  acromioclavicular joints, the posterior tibiotalar, lateral talocalcaneal
  and intercuneiform ligaments, the tendon sheath of the extensor hallucis
  longus, the intertubercular tendon sheath and the tendon sheaths of the
  flexor carpi radialis, flexor pollicis longus, extensor pollicis longus and
  extensor digiti minimi); the intercornual ligaments and the
  radioscaphocapitate, triquetrocapitate and ulnotriquetral ligaments of the
  wrist (two flat faces each), the triradiate
  cartilage, and five ankle and foot ligaments that are flat four-vertex
  placeholders (anterior and posterior talofibular, calcaneofibular, dorsal
  calcaneocuboid, plantar calcaneonavicular).
- Meshes keep their original vertices and triangles; closed surfaces were
  oriented outward and given smooth vertex normals. The box holds the whole
  body, so no mesh or curve is cut. Curves were drawn as tube surfaces with the head model's
  construction (bevel depth x point radius, 20 radial and 18 per-segment
  samples), keeping only the samples needed for the tube path and radius to
  stay within 0.05 mm of the sampled curve (the kept samples are original
  curve samples).
- Renamed source objects: the middle cerebral artery segments, spelled
  "M3 segment" and "M3-segment" on the two sides, as M1, M2 and M3; the two
  lateral temporomandibular ligaments, which carry each other's side suffix,
  by position; the
  doubled dot of the posterior lateral nasal branches of the sphenopalatine
  artery and the brackets of the accessory parotid gland removed;
  Left/Right testicular artery and vein to the
  side-suffix convention; "Descending branch of lateral circumflex femoral
  artery" (right side, no suffix) and the left "Iliocostalis colli muscle" to
  their side-suffixed names; the trapezius parts by position (the source
  labels them the other way round; the lower part from the thoracic spines is
  the ascending part and the upper part from the occiput the descending
  part); a second "Inferior vein of left ventricle" with a
  placeholder suffix as "(second)"; and four bowel objects by position and
  shape: "Sigmoid colon" (from the end of the sigmoid loop to the pelvic floor)
  as Rectum, "Descending colon" as Descending and sigmoid colon, "Ascending
  colon" as Caecum and ascending colon, and the curve "Jejunum" as Jejunum and
  ileum. Wrote English labels and descriptions (the labels call the source's
  "fingers of foot" toes and its numbered "fingers of hand" thumb, index,
  middle, ring and little finger).
- The viewer draws the low-polygon genital, urinary, digestive, heart, lung,
  lymph-node, bursa, meniscus and fat-pad meshes with PN-triangle smoothing
  through their original vertices and starts with the platysma and the
  fasciae (including the investing cervical, deltoid, brachial, antebrachial
  and dorsal hand fasciae), the chest and
  abdominal walls, the pleura, the pericardium, the greater omentum and the
  small intestine faded; the GLB is unchanged by either.
Authored schematic structures on the whole male body page (pelvis-male.glb):
the pericardium and the right and left phrenic nerves are in neither
Z-Anatomy nor BodyParts3D, so they were drawn for this atlas (no source
model) and fitted to the page's Z-Anatomy structures; they are shared with
the page under CC BY-SA 4.0. Their shape and course are illustrative, not
measured; the records carry "schematic": true and the viewer marks them
"Schematic".
- Pericardium: a closed sac about 3 mm outside the heart chambers and the
  roots of the ascending aorta, pulmonary trunk, venae cavae and pulmonary
  veins, bridged across the clefts between them and pressed in around the
  lateral pericardial nodes (1 mm voxel offset, closing, Gaussian smoothing,
  marching cubes, quadric simplification to 25,920 triangles).
- Phrenic nerves: 1.1 mm-radius tubes along smoothing splines through
  waypoints on the front of the anterior scalene, behind the subclavian vein
  and in front of the subclavian artery, beside the brachiocephalic vein and
  superior vena cava (right) or over the aortic arch (left), then on the
  lateral surface of the schematic pericardium into the diaphragm.
Spinal cord on the whole male body page (pelvis-male.glb): from the HuBMAP
Human Reference Atlas, spinal-cord-male v1.1 (3d-vh-m-spinal-cord.glb, Visible
Human Male; CC BY 4.0, see SOURCES), placed with VH_Male/v1.2/VH_M_Vertebrae.glb
from the CCF 3D Reference Object Library. Changes:
- Selected the 30 segments C1 to S5 with their original triangles.
- Fitted each HRA vertebra to the Z-Anatomy vertebra of the same name
  (similarity ICP with its neighbours; mean surface distance 1.2-2.3 mm) and
  moved every cord vertex with a blend of the two vertebrae bracketing its
  height; then centred the cord in the Z-Anatomy dural sac slice by slice
  (median shift 5.0 mm, at most 8.1 mm). Where the Z-Anatomy dural sac is
  narrower than the cord (cervical enlargement, upper thoracic levels) the
  cord passes it by up to 4.0 mm.
- Wrote English labels and descriptions. CC BY 4.0 material may be included
  in this CC BY-SA 4.0 page with this credit.
Tested and not used on the male page: the BodyParts3D 4.0 kidneys (FJ3145,
FJ3147) and the HRA Visible Human Male kidneys (kidney-male-left/right v1.3);
neither fits the renal vessels and neighbouring organs of the Z-Anatomy body.

included in this CC BY-SA 4.0 page with this credit. Changes:
- Selected 74 elements: the cortical gyri and lobes as BodyParts3D divides
  them, the insula, cerebral white matter, corpus callosum, fornix and its
  commissure, hippocampus, amygdala, caudate nucleus, putamen, globus
  pallidus, thalamus and its stria medullaris, hypothalamus, pineal body,
  the ventricles, cerebral aqueduct and choroid plexus, midbrain, cerebral
  peduncles, pons, medulla oblongata and cerebellum. Left out: the
  tentorium cerebelli (its edge lies 11.7 mm from the page's straight sinus).
- Moved all of them by one similarity transform (uniform scale 0.974,
  rotation 0.06 degrees, translation) fitted by ICP of the BodyParts3D
  frontal, parietal, occipital, temporal and sphenoid bones onto the
  Z-Anatomy bones of the page (median distance 0.13 mm); the bones
  themselves are not used. Vertices and triangles are otherwise unchanged;
  closed surfaces were oriented outward and given smooth vertex normals.
- Wrote record names with .l/.r by position ("Left half of" for the
  midline structures BodyParts3D splits in two) and English descriptions.

VH_Female/v1.4/3d-vh-f-blood-vasculature.glb. Changes:
- Selected 337 named parts of the trunk: the heart (chambers, septum,
  papillary muscles, valves), the lungs in their twenty bronchopulmonary
  segments with the hila, the trachea, carina, bronchi and their cartilages,
  the thymus, the liver capsule and peritoneal ligaments, gallbladder, bile and
  pancreatic ducts, pancreas, duodenum, spleen surfaces, kidneys (fibrous
  capsule, cortex, renal columns, pyramids, hilum), colon, small intestine, the
  pelvic organs and ligaments, hip bones, sacrum, coccyx, C7, the thoracic and
  lumbar vertebrae, the spinal cord in segments from C8 to S4, and the aorta,
  venae cavae and the thoracic, abdominal and pelvic vessels; and 20 parts of
  the neck: C1 to C6, the spinal cord segments C1 to C7 and the thyroid,
  cricoid, arytenoid, corniculate and epiglottic cartilages (from VH_F_Lung).
  Kept their original vertices, triangles and normals in the source frame (no
  registration), except where noted below. No selected HRA part crosses the
  region box (x -250 to 250 mm, y -910 to 725 mm, z -190 to 70 mm, from the
  feet to the skull base), so none is cut.
- Left out: the liver segments and surface areas (they coincide with the
  liver capsule) and the lobar subdivisions of the pulmonary hila (they
  duplicate the hilum surfaces). Joined the two source pieces of each branch of the aortic arch into
  one surface.
- Named the parts from their node identifiers with sides from position; named
  the two round ligaments by position (the source labels them the other way
  round), the part labelled "abdominal ostium of uterine tube", which lies at
  the uterine horns, as the uterine openings of the tubes, the node
  VH_F_superior_rectal_vein (labelled "superior rectal artery") as the vein,
  the papillary muscles of the heart by position (the source's medial one of
  the right ventricle as septal), and the ventral and dorsal pancreatic ducts
  as the main and accessory ducts. Wrote English labels and descriptions;
  assigned categories and materials.
- The viewer starts with the small intestine and the ascending and descending
  colon faded; the GLB is unchanged by it.
Female hip, thigh, leg and foot (same GLB): adapted from the University of
Denver Center for Orthopaedic Biomechanics, 3D Models of the Visible Human
Female, final 3D STL models (CC BY 4.0; see SOURCES). Changes:
- Selected 124 parts, 62 on each side: 38 pelvic-wall, gluteal, hip, thigh and
  leg muscles; the femur, patella, tibia, fibula, the seven tarsal bones and
  the file "Phalanges" (which also holds the metatarsals, named for both);
  the cartilage of the hip, knee and ankle; the cruciate and collateral
  ligaments of the knee. Removed stray pieces of fewer than 10 vertices from
  three files. The DU hip bones, sacrum and coccyx were used only for the fit.
- Placed them in the HRA frame by one similarity transform (scale 1.041) fitted
  between the DU hip bones, sacrum and coccyx and the HRA compact hip-bone
  layers, sacrum and coccyx (mean surface distance 1.6 to 1.9 mm, coccyx 3.1).
- Where a DU muscle or cartilage overlapped an HRA bone, moved its vertices to
  0.1 mm outside the bone with a smooth falloff (at most 1.9 mm). Where an HRA
  ligament, vein, bowel loop or the right kidney passed through a DU muscle,
  moved the HRA vertices out of the muscle in the same way (at most 11 mm, 18
  parts; the right kidney capsule and cortex at most 3.4 mm) and recomputed
  their normals. The upper psoas was moved off the HRA lumbar vertebrae in the
  same way (at most 1.8 mm).
- None of the parts crosses the region box, so none is cut; wrote English
  labels and descriptions (noting where a leg muscle's tendon is not in the
  source).
Female knee (same GLB): from the HRA knee files listed above, 10 parts: the
medial and lateral menisci (one source mesh per knee, split into its two
pieces and named by position), the patellar ligament, the tendon of the
quadriceps femoris and the anterolateral ligament of each knee. Changes:
- Placed each knee by its own similarity transform fitted between the HRA
  distal femur, patella, proximal tibia and fibula and the DU bones of the page
  (scale 0.981 and 0.984, rotation 8.0 and 11.0 degrees, mean surface distance
  1.0 to 1.4 mm). The HRA knee bones were used only for the fit; the HRA
  cruciate and collateral ligaments, which the DU models have, are not used.
- Moved their vertices out of the DU bones and knee cartilage to 0.1 mm outside
  with a smooth falloff (at most 3.4 mm) and recomputed their normals; overlaps
  of at most 0.3 mm remain where the menisci lie between the femoral and
  tibial cartilage.
Female shoulders, arms, hands and chest wall (same GLB): adapted from BoneHub,
Visible Human Full-Skeleton 3D Bone Models (S. H. Alavi and M. Asseln,
University of Twente; CC BY 4.0; see SOURCES), segmented from the University
of Denver aligned CT of the Visible Human Female; files
visible_human_3d_models/CT/Mesh/02_Female/ UPPER_EXTREMITY_LEFT/RIGHT,
HAND_LEFT/RIGHT and THORAX (.stl). Changes:
- Selected 71 bones: on each side the clavicle, scapula, humerus, radius,
  ulna, the eight carpal bones, the five metacarpals and the phalanges of each
  finger (one surface per finger in the source, named for the whole), and the
  twelve ribs; and the sternum (one surface for its three parts in the
  source). The BoneHub vertebrae, sacrum, hip bones and femurs were used only
  for the fit.
- Welded the STL vertices and computed area-weighted normals of the full
  surface; simplified each bone within 0.05 mm of its surface (meshoptimizer,
  absolute error; 1,916,120 to 421,150 triangles), the kept vertices keeping
  their positions and normals.
- Placed them in the HRA frame by one similarity transform fitted between the
  BoneHub C7 and thoracic vertebrae and the HRA vertebrae of the page (scale
  0.997, mean surface distance 0.8 mm; 1.2 to 2.4 mm from L1 to the sacrum,
  which were not fitted), as both come from the same specimen.
- Wrote English labels and descriptions. As the BoneHub documentation notes,
  the CT does not fully cover the elbows, so the distal humeri and the
  proximal radii and ulnae are incomplete (said in their descriptions), and
  the costal cartilages are not segmented, so the ribs end short of the
  sternum.
Female head, breasts, intervertebral discs and further organs (same GLB):
adapted from the HuBMAP Human Reference Atlas reference organ digital objects
(https://cdn.humanatlas.io/digital-objects/ref-organ/, CC BY 4.0): mouth-female
v1.0 (3d-vh-f-mouth.glb), eye-female-left/right v1.3, brain-female v1.4
(3d-allen-f-brain.glb: the Allen Human Reference Atlas 3D brain of an adult
female donor, Allen Institute for Brain Science, as placed by the HRA in the
Visible Human Female), intervertebral-disk-female v1.0,
mammary-gland-female-left/right v1.1, omentum-female v1.0,
epiploic-appendage-of-transverse-colon-female v1.0 and
renal-pelvis-female-left/right v1.0; and from BoneHub (see above), files
visible_human_3d_models/CT/Mesh/02_Female/SKULL/SKULL_CRANIAL_MAXILLA and
SKULL_MANDIBLE (.stl). Changes:
- Selected 406 HRA parts: 21 of the mouth, 23 of each eye, 268 brain regions
  and the optic chiasm, 24 intervertebral discs with their nuclei pulposi,
  8 parts of each breast, the greater omentum, the epiploic appendages, the
  two renal pelves and the two palatine tonsils (palatine-tonsil-female-left/
  right v1.2); and the BoneHub cranium (with the maxillae, one surface)
  and mandible. Left out: the HRA skin (posed with the arms raised; it does not
  match the bones of the page), six Allen regions of 6-9 vertices, and the
  Allen frontal pole, frontomarginal gyrus, atrium of the lateral ventricle and
  posteroventral putamen of both sides, whose positions contradict their
  names (label-position check of every region against its lobe or parent).
- Simplified the HRA parts within 0.05 mm (meshoptimizer; 4,548,099 to
  1,170,098 triangles) and the skull within 0.05 mm (907,232 to 135,598
  triangles); kept vertices keep their positions and the normals of the full
  surface. The HRA parts share the page's frame and were not moved, except
  the brain (below).
- Placed the skull by a similarity fit of BoneHub C1-C3 onto the HRA C1-C3 of
  the page (mean surface distance 0.6-0.8 mm), and closed the mandible, which
  is slightly open in the CT, onto the HRA lower teeth and gingiva by one rigid
  fit (5.7 degrees; condyles 0.2-0.4 mm from the mandibular fossae).
- Fitted the Allen brain into the cranial cavity of this skull by one
  similarity transform (scale 0.919, rotation 0.4 degrees, translation 2.5 mm;
  cortex beyond the inner table 9.5% -> 0.7%).
- Named the parts in English with descriptions; the Allen regions by position
  (the file labels their hemispheres the other way round), midline Allen
  structures as left and right halves, the discs by the two vertebrae each
  joins.
- The female GLB and its metadata are offered under CC BY 4.0. No
  endorsement by HuBMAP, the HRA, the Allen Institute, the University of
  Denver, BoneHub, the University of Twente or the model creators is implied.
Female body, CT-segmented structures (same GLB): segmented by TotalSegmentator
2.18 (https://github.com/wasserth/TotalSegmentator; code and the open-licence
tasks used here under Apache-2.0; https://doi.org/10.1148/ryai.230024) from the
Visible Human Female normal CT, courtesy of the U.S. National Library of
Medicine (https://data.lhncbc.nlm.nih.gov/public/Visible-Human/, files
Female-Images/radiological/normalCT c_vf1001-c_vf1985 with their headers;
NLM Terms and Conditions,
https://www.nlm.nih.gov/databases/download/terms_and_conditions.html). Changes:
- Resampled exam 370 (head to upper thighs, 1 mm slices) to a 1 mm grid and
  ran the tasks "total", "headneck_muscles", "head_muscles",
  "headneck_bones_vessels", "oculomotor_muscles" and "abdominal_muscles" (the
  last in three blocks overlapping by 100 mm, joined in the middle of each
  overlap) on the CPU.
- Fitted the segmented bones to the bones of the page by similarity fits per
  region (mean surface distance 0.7-2.5 mm) and carried every structure by a
  distance-weighted blend of these fits; trimmed each where it met a structure
  already on the page (contact within 1 mm allowed).
- Kept 74 of 96 structures: those with at most 25% of their volume and at
  most 8 mm of depth overlapping the page, both sides of a pair (for the air
  spaces inside the skull the skull itself was not counted, and at least half
  had to lie inside it); left out the masseter, medial pterygoid, superior
  oblique, levator palpebrae, thyrohyoid, external acoustic meatus, iliac
  arteries, nasal cavities, nasopharynx and pericardium (outer 2 mm of the
  segmented sac) (over the limits), the digastric and the oropharynx
  (incomplete) and the superior pharyngeal constrictor (nothing left after
  trimming). Smoothed the abdominal-muscle masks along the body axis and
  closed holes of up to 6 cm2 in the latissimus dorsi and trapezius sheets.
- Extracted surfaces by marching cubes from the lightly smoothed masks,
  smoothed them (Taubin) and simplified them within 0.2 mm (meshoptimizer;
  3,234,414 to 169,028 triangles); named them from the TotalSegmentator
  classes with English descriptions, stating where a muscle is only partly
  segmented (rectus abdominis to L5, erector spinae and transversospinalis to
  T3, serratus anterior to T4) and that only the lower costal cartilages were
  found. No endorsement by the NLM or the TotalSegmentator authors is implied.
Both pages: nearby-structure lists computed as for the head model. They are
general reference anatomies, not patient scans or clinically validated models.

ILLUSTRATIVE SURFACE DETAIL
The default Realistic tissue display adds independently authored procedural
surface shading in the viewer: bone pores, enamel and root tones, muscle,
tendon and ligament fibres, tongue papillae, gingival stippling, mucosa and
gland lobules, computed at display time from 3D noise without UV maps, plus
nerve-sheath grain, subtle vessel-wall texture and fibrous lymph-node capsule
texture. Atlas colors restores the category-color display. Fibre directions
follow each mesh's dominant direction or simplified textbook layouts; they
are not measured fibre orientation. The nerve exterior remains sheathed;
no bare braids, invented capillary networks or raised lymphoid follicles are
added. These surface patterns and their optical appearance are illustrative,
not scan-derived microanatomy or measurements of tissue color and material.
Existing Z-Anatomy anatomy supplies the routes, branches and placement of the
nerves and vessels. Denser curve tessellation or capsule smoothing refines the
existing representation; it is not new measured anatomy. No new scan was used
for these surface details, and no patient-specific realism is guaranteed.
No individual lymph-node hilum was added because its orientation is unmeasured.
The downloadable GLB embeds 12 independently authored procedural PNG maps:
color, normal and roughness for nerves, arteries, veins and lymphatic tissues.
These material maps are part of this adaptation and contain no copied source
photographs. Normal maps affect surface lighting, not anatomical geometry.
The viewer offers Realistic tissue and Atlas colors; changing the runtime
display mode does not modify the downloadable GLB file.

DENTAL GEOMETRY VERIFICATION
Registration comparisons use 12,000 deterministic area-weighted surface samples
in each direction and nearest-triangle distances against the existing atlas.
Across the accepted 20 surfaces, the greatest per-direction RMS is 0.019924 mm,
the greatest 95th percentile is 0.041844 mm, and the greatest sampled distance
is 0.128253 mm (all rounded upward). These measure agreement with the existing
atlas, not agreement with a patient, and do not prove a continuous Hausdorff
bound. Candidates exceeding the 0.2 mm maximum-sample gate were not integrated.
Per-structure metrics and source part IDs are included in structures.json.

SCOPE OF UPSTREAM LICENSE NOTICES
The complete upstream repository has a CC BY-NC-SA 4.0 distribution notice,
which is retained unmodified as UPSTREAM-DISTRIBUTION-LICENSE.txt. That notice
identifies the inner-ear and kidney models as the sources of its NonCommercial
restriction and expressly describes redistribution of the remaining model
subset under CC BY-SA 4.0 after those components are removed.

This selected subset excludes all kidney, inner-ear and brain meshes, including
the named "Kidney", "Anatomy of the Inner Ear", "Brainder" and "White matter"
components. The whole male body page (pelvis-male.glb, read from the
Z-Anatomy Blender file, whose License.txt names the same models) excludes them
in the same way: its kidneys, renal pelves and intrarenal vessels, its cochlea,
vestibule and cochlear nerve mesh and all its brain objects are left out (the
brain on that page is BodyParts3D 4.0, CC BY 4.0). The kidneys on
the female page are HRA files under CC BY 4.0, not Z-Anatomy. No license
is asserted here for the excluded components. The full upstream notices remain
available for provenance and must not be read as a claim that every component
named in those notices is present in this subset.
The nqwrc application code, build configuration and structure-definition text

모델 변경사항
- 골격, 내장, 근육, 신경, 심혈관, 림프, 관절의 7개 해부 계통에서 구강 및
  인접 구조 233개를 선택했습니다. 이후 그중 6개에서 이름 붙은 신경 가지 14개를,
  2개에서 이름 붙은 동맥 가지 4개를 분리하여 이름별 구조는 251개가 되었고, 이후
  같은 원본에서 구조 10개를 추가하여(아래 참조) 261개가 되었고, 이어
  BodyParts3D 4.0에서 입천장 근육 4개를 추가하여(아래 참조) 265개입니다.
- 선택한 구조를 하나의 glTF 2.0 GLB로 통합하고 나머지 구조를 제외했습니다.
  현재 GLB는 21,876,824바이트로 무손실 EXT_meshopt_compression을 사용하며
  호환 뷰어·가져오기 도구가 필요합니다. 양자화·손실 필터는 사용하지 않았습니다.
  디코딩 후 부동소수점 속성값과 삼각형 정점 순서의 보존을 확인했습니다.
- 17개 구조에 원래 Z-Anatomy Blender 제작자의 렌더용 세분화 설정을 적용했습니다.
  곡면을 매끄럽게 하며, 측정한 미세 해부 구조를 새로 추가하지 않습니다.
- 공개된 BodyParts3D 3.0_95의 더 촘촘한 전체 치아 표면 18개를 해당 아틀라스
  치아에 정합했습니다. 치아별로 회전, 균일 배율, 이동을 한 번씩 적용했으며,
  비강체 변형이나 새 조각 작업은 하지 않았습니다. 해당 치아의 삼각형 합계는
  28,520개에서 137,716개로 늘었습니다. 왼쪽 대응 구조는 기존 Z-Anatomy의
  양측 대칭 구성에 맞춰 반사했습니다.
- 이후 BodyParts3D 3.0_95 표면 FMA55705를 아래턱 첫째큰어금니 양쪽의 바깥
  치관·치근 표면(삼각형 1,836개)에 같은 방식으로 정합하고(균일 배율 1.0311,
  RMS 0.017 mm, 최대 표본점 0.097 mm) 그 표면만 교체했습니다. 원본 Dentine
  표면과 안쪽 법랑질 껍질은 그 안에 그대로 둡니다. 이로써 정합한 치아 20개의
  삼각형은 155,352개입니다(이전 32,192개).
- 교체하지 않은 치아 8개와 혀(정점 343개 / 삼각형 682개)는 원본 메시를
  유지합니다. BodyParts3D와의 정합 기준을 통과하지 못했으며, 3.0판에는 혀와
  사랑니가 없습니다. 이후 표면 개선에서도 삼차신경 뿌리 네 개는
  이전 형상을 유지합니다.
- 원본 아틀라스의 치관·치근 재질 역할을 가장 가까운 표면의 대응 관계를 이용해
  개선한 치아에 옮겼습니다. 이러한 시각적 재질 영역은 법랑질, 상아질, 백악질,
  치수 또는 치주 조직층을 각각 측정하여 구성했음을 뜻하지 않습니다.
- 영문 해부학 식별자(za_name), 기존 해부 위치와 원본 재질 역할을 유지했습니다
  (아래의 좌우 수정 한 건 제외). 자체 작성 한국어 이름·간단한 설명, 분류 식별자,
  세부 출처 메타데이터와 측정한 경계를 추가했습니다. 원본의 구조 정의 문장은
  재사용하지 않았습니다.
- 원본에서 이어받은 좌우 이름 하나를 바로잡았습니다. 아틀라스 좌표계에서 +x는
  인체 왼쪽이며 다른 모든 짝 구조는 이름에 적힌 쪽에 있지만, .l로 이름 붙은
  가쪽턱관절인대는 인체 오른쪽(경계 중심 x 약 -53.2 mm, 아래턱뼈와 오른쪽
  구조에만 맞닿음)에, .r로 이름 붙은 인대는 왼쪽에 있었습니다. GLB에서 이름
  붙은 두 노드의 배치(이동, 거울상 변환, 메시 참조)를 맞바꾸어 이제 각 인대는
  실제로 놓인 쪽의 이름·한국어 이름·설명을 갖습니다. 메시 데이터와 모든
  primitive는 바이트 단위로 같으며, 경계와 주변 구조 목록을 갱신했습니다.
  이제 npm run check는 .l 구조가 x <= 0에 있거나 .r 구조가 x >= 0에 있으면
  실패합니다.
- 이번 표면 업데이트는 원본 곡선 80개(신경 26개·동맥 36개·정맥 18개)와
  림프절·편도 구조 20개, 총 100개의 형상을 다듬습니다. 곡선의 제어점·핸들·
  반지름·분지·월드 변환은 그대로이며 림프조직 표면에는 Catmull-Clark 세분화
  두 단계를 적용했습니다.
- 그 표면 업데이트에서 구조 132개의 형상은 변하지 않았으며 치아 28개와
  삼차신경 뿌리 네 개가 여기에 포함됩니다. 조직 재질과 UV 질감 좌표는 104개
  구조에 적용했고, 신경 뿌리 네 개는 형상 변화 없이 이 재질·UV 업데이트만
  받았습니다.
- 원본 Z-Anatomy 나비뼈(정점 3,650개 / 삼각형 7,308개)를 뼈·봉합 재질 역할과
  함께 추가했습니다. 더 촘촘한 BodyParts3D 3.0 FMA52736 표면을 회전·균일
  배율·이동으로 정합해 보았으나 Z-Anatomy 표면과의 RMS 0.73 mm, 95백분위
  1.37 mm, 최대 7.6 mm로 치아 정합 기준을 넘어 사용하지 않았습니다.
- 기존 위턱신경·아래이틀신경·얼굴신경의 스플라인 표면에서 이름 붙은 신경 가지
  14개(좌우 각 7개)를 분리했습니다: 눈확아래신경, 앞니신경, 얼굴신경의
  관자가지·광대가지·볼가지·아래턱모서리가지·목가지. 원래 삼각형은 모두 정확히
  한 번씩 유지되며, 위턱신경과 얼굴신경 줄기를 나눈 자리만 평평한 마개로
  닫았습니다. 원본 스플라인에는 이름이 없으므로 가지의 이름은 주행 경로에 따른
  해석이며(DETAILS.html 참조) 별도 출처의 해부 자료가 아닙니다. 그 밖의 구조
  형상은 변하지 않았습니다.
- 위턱동맥에서 이름 붙은 동맥 가지 4개(좌우 각 2개)를 이름 없는 원본 스플라인
  단위로 옮겨 분리했습니다: 중간위이틀동맥(눈확아래고랑에서 눈확아래동맥을
  떠나는 스플라인과 잔가지)과 뒤위이틀동맥 치아가지(위턱뼈결절을 따라 내려가는
  스플라인과 잔가지). 스플라인을 자르지 않았고 원래 삼각형은 모두 정확히 한 번씩
  유지되며, 이름은 스플라인 주행 경로에 따른 해석입니다.
- 같은 Z-Anatomy Blender 파일에서 정합 검사를 통과한 구조 10개를 추가했습니다:
  좌우 이마근, 눈둘레근 눈확부분·눈꺼풀부분, 넓은목근, 미주신경(제10뇌신경).
  같은 파일에서 읽은 기준 구조 8개가 고정된 축 변환 후 GLB와 0.006 mm 이내로
  일치하므로 따로 맞추지 않았습니다. 각 근육은 닫힌 표면이며 뼈 안쪽 0.5 mm보다
  깊은 부분이 최대 0.1%로 기존 얼굴근육(최대 3.0%)을 넘지 않습니다. 이마근과
  넓은목근은 아틀라스 범위 상자에서 자르고 마개로 닫아 모델 경계와 중심이 바뀌지
  않습니다. 미주신경은 아틀라스 신경 곡선과 같은 방식으로 만들었고 줄기는
  아틀라스 범위를 벗어나는 곳에서 잘랐습니다. 기존 primitive는 모두 바이트 단위로
  같습니다. 붓혀근과 입천장혀근은 원본 메시가 없어 모식도 경로로만 그립니다(아래).
- BodyParts3D 4.0(위의 단순화 사본)에서 좌우 입천장올림근과 입천장긴장근을
  추가했습니다. BodyParts3D 4.0은 아틀라스 좌표계와 다르므로 주변 구조 9개
  (나비뼈, 위턱뼈, 관자뼈, 입천장인두근, 위인두수축근)에 하나의 닮음 변환(배율
  0.9831, 고정된 축 변환 외 회전 0.34도)을 함께 맞췄고, 그 결과 이 구조들은
  아틀라스 표면과 중앙값 0.24-0.49 mm(RMS 최대 1.23 mm) 이내에 놓입니다. 각
  근육은 닫힌 표면이며 뼈 안쪽 0.5 mm보다 깊은 부분은 0-2.2%입니다(주변 기존
  근육: 0-4.2%). 모델 경계와 중심은 바뀌지 않았고 기존 primitive는 모두 바이트
  단위로 같습니다. 한국어 이름과 설명은 자체 작성했습니다.
- 현재 모델: 이름별 구조 265개, 정점 922,089개, 삼각형 1,723,532개.
- 주변 구조 목록에는 이 형상에서 계산한 표면 간 최단 거리와 대략적인 접촉
  면적을 저장합니다. 임상 측정값이 아닙니다.
- 선택 사항인 모식도 레이어(src/schematic-data.json, tools/schematic/derive.mjs
  로 생성)는 원본에 없는 위이틀신경·입천장신경·코입천장신경, 혀동맥·혀밑동맥,
  위턱굴을 그립니다. 경로는 이 파생 모델의 기준점(동행 동맥, 신경 줄기, 치근
  끝, 뼈 표면)을 따릅니다. 설명용 그림이며 실측 해부 구조가 아니고, GLB와 구조
  수에 포함되지 않습니다.
- 탐색기는 화면의 색상, 조명, 광택, 불투명도와 절단 표시를 바꿉니다.
  구조 탐색에서는 온전한 구조를 10개 유형의 보드로 이동시키며, 좌우 쌍을
  나란히 배치하고 각 구조의 크기와 형상을 유지합니다. 이러한 실행 중 화면
  변화는 다운로드하는 GLB를 바꾸지 않습니다. 해부 위치는 조립된 해부 위치를
  복원합니다. 탐색기와 문서는 원본 이름·제3자 고지를 변경하지 않고 영어와
  한국어로 표시합니다.
- 화면 음영은 사진 수준의 조직색, 미세 표면 측정 또는 개인별 임상 정확도를
  재현했다는 주장이 아닙니다.

표현용 표면 디테일
기본 실제 조직 질감 표시는 탐색기에서 자체 제작한 절차적 표면 음영을
적용합니다. 뼈의 미세공, 법랑질·치근 색조, 근육·힘줄·인대의 결, 혀 유두,
잇몸 점묘, 점막과 샘 소엽을 UV 맵 없이 3D 노이즈로 화면 표시 시점에 계산하며,
신경집 결, 은은한 혈관벽 질감과 림프절 섬유성 피막 질감도 적용합니다.
아틀라스 색상은 분류별 색상으로 전환합니다. 근섬유 방향은 메시의 주된
방향이나 단순화한 교과서적 배열을 따르며 측정한 근섬유 방향이 아닙니다. 신경은 피막으로 덮인 외형을 유지하며 노출된 꼬임 다발, 임의의
모세혈관망이나 솟은 림프소절을 추가하지 않습니다. 표면 무늬와 광학 표현은
예시용이며 스캔에서 얻은 미세 해부 구조나 조직색·재질의 측정값이 아닙니다.
신경·혈관의 경로, 분지와 위치는 기존 Z-Anatomy 해부 자료를 따릅니다.
곡선 메시의 밀도를 높이거나 피막을 매끄럽게 하는 작업은 기존 표현을 다듬는
것이며 새로 측정한 해부 구조가 아닙니다. 이 표면 디테일에는 새 스캔을
사용하지 않았으며 특정 사람과 똑같은 사실성을 보증하지 않습니다.
각 림프절의 문 방향을 측정하지 않았으므로 임의의 문을 추가하지 않았습니다.
다운로드 GLB에는 자체 제작한 절차적 PNG 맵 12개가 포함됩니다. 신경·동맥·
정맥·림프조직 유형마다 색상·노멀·거칠기 맵을 제공합니다. 이 재질 맵은 이번
편집물의 일부이며 원본 사진을 복제하지 않았습니다. 노멀 맵은 표면 조명에
영향을 주며 해부 형상을 추가하지 않습니다. 탐색기는 실제 조직 질감과 아틀라스
색상을 제공하며, 실행 중 표시 모드를 바꾸어도 다운로드 GLB가 수정되지는 않습니다.

치아 형상 검증
정합 비교에는 각 방향으로 12,000개의 결정론적 면적 가중 표면 표본점과 기존
아틀라스에 대한 최근접 삼각형 거리를 사용했습니다. 채택한 20개 표면에서
방향별 RMS의 최댓값은 0.019924 mm, 95백분위의 최댓값은 0.041844 mm,
최대 표본점 거리는 0.128253 mm입니다. 모두 위로 반올림한 값입니다.
이는 기존 아틀라스와의 일치도를 나타내며 환자와의 일치도를 뜻하지 않습니다.
연속 표면 전체에 대한 하우스도르프 거리 상한도 증명하지 않습니다.
최대 표본점 거리 0.2 mm 기준을 넘은 후보는 통합하지 않았습니다.
구조별 측정값과 원본 부위 ID는 structures.json에 포함되어 있습니다.
