Adaptations: axes and units converted from millimeters/Z-up to meters/Y-up; translated to rest at the stage; geometry simplified using meshoptimizer with 0.2% relative error limit per structure; normals quantized to signed 16-bit; packed into binary chunks; curated display system groupings and colors. The source contains 2,234 individual OBJ meshes; all remain represented. The combined hierarchy contains 3,432 named FMA concepts, which may reference multiple meshes. Original source identity is preserved in the manifest.

Source OBJ comments mention an older CC BY-SA 2.1 Japan license. The official current database license linked above supersedes that legacy text and explicitly permits redistribution and adaptation under CC BY 4.0.

BodyParts3D represents an adult male reference anatomy based on TARO MRI and anatomical illustration refinements. It is not a complete model of every possible human anatomical structure or variation. This interface is educational and is not a clinical tool.

Adaptations: translated native meter/Y-up coordinates onto the stage, coincident vertices welded and source normals averaged, geometry simplified with a 0.2% per-structure relative error bound, and normals quantized. Colors and display systems are curated for this interface. All 888 source meshes are represented, with 1,073 source nodes available as selectable individual or compound concepts.

This is a reference assembly with whole-body surface and selected organs, including female reproductive anatomy. Its skeleton and muscle coverage is partial. It is not a complete model of every human structure or a single-person scan. Eight placenta/umbilical structures are classified under Pregnancy reference and hidden by default.


## DentalSHOW extraction
Oral/facial subset extracted from the supplied optimized atlas. Vertices translated by (0, -1.55, -0.04) meters, without rotation or scaling. Source geometry and topology otherwise preserved. Dental nodes assigned FDI numbers by source labels. Exported to glTF 2.0 binary with separate nodes and illustrative materials. No anatomy was reconstructed or clinically validated in this extraction.


## DentalSHOW: dentatura a 32 elementi
Aggiunti FDI 18, 28, 38, 48 come copie traslate dei secondi molari 17, 27, 37, 47. Nessuna nuova anatomia clinicamente validata. Le geometrie di origine restano identiche. La posizione delle copie è illustrativa.

## Revisione DentalSHOW del 11 settembre 2026
Ricostruite le superfici posteriori continue di osso e gengiva intorno ai quattro terzi molari, mantenendo inalterata la posizione dei denti. Eliminato definitivamente il nodo Lip; mantenuta Tongue. Aggiunti metadati cervicali per separare corona e radice nell’app. Tutti gli adattamenti sono illustrativi.

Nella revisione finale sono state chiuse anche piccole esposizioni radicolari presenti nella base originale, con modifiche locali alle due porzioni del mascellare e alla mandibola. Denti, gengive, lingua e riferimenti cervicali sono rimasti invariati.
