The Bones example models are simple geometric shapes of bones and cartilage, with no HAnim structural nodes included. They are suitable for composition and reuse in HAnim models by loading via either Inline or InlineGeometry nodes.

These models are improved versions of Shape geometry found in the originals subdirectory with naming changes recorded in CHANGELOG.md. These results provide full anatomical fidelity for all human joints and bones (segments). Design includes correct names to match the HAnim specification, manageable file sizes, and portability for reuse.

These examples were first published in X3D Example Archives: Basic, Medical and support the work of the Web3D Humanoid Animation (HAnim) Working Group. This directory holds third-generation HAnim updates of those original geometry-only examples.

The majority of these bones are connected to animatable joints and can be found, with the same names, in HAnim Level of Articulation (LOA)-4, defined at Humanoid Animation (HAnim) Architecture specification draft version 4.1, clause 4 Concepts, section 4.11.6.5 LOA‑4 hierarchy. Additional models listed here (such as teeth and cartilage) can someday get adopted in the HAnim Specification draft version 2.1 in a new section defining Level of Articulation LOA-5.

TODO: rename/reuse original cartilage models, and restore missing models c1disc.x3d and l_tarsal_distal_phalanx_5.x3d.
