Modifications by this project: selected spine, intervertebral discs, ribs,
sternum, shoulder and pelvic bones, and skin; cropped skin below the upper
thighs; coordinate conversion; welded vertices and recomputed smooth normals;
Meshopt compression and GLB packaging. Bone mesh topology is retained.
Rendering materials and region metadata are customized for the report.

This is a generic adult anatomical reference, not a patient scan, not a
clinical measurement, and not evidence of the user's actual spine shape.

2026-10-16: Integrated user supplied spine-3d.zip BodyParts3D meshes: 25 vertebral/sacral parts, 2 pelvic bones, 22 discs and 14 paraspinal muscles. Their OBJ headers carry the same CC BY-SA 2.1 Japan license. The existing T12 intervertebral disc and other context meshes are retained. At that stage, disease-state GLB and Blender projects were not distributed. See the later teaching-model addition below. Original input hashes and provenance are recorded per part in manifest.json.

2026-10-16 additional teaching models: assets/pathology contains split user-provided disease-state GLB assets, plus explicitly illustrative localized posterior protrusion deformations of healthy disc meshes. Adapted assets shared under CC BY-SA 2.1 Japan based on their original OBJ attribution; no patient data. See ../pathology/manifest.json.
