The Atlas · Anatomy the way the Codex reads it

Nothing selected

The reference head

Bone from the BodyParts3D adult male reference skeleton (Database Center for Life Science, CC BY 4.0), loaded as real geometry: seventy-six structures, every one selectable. Surface from the MediaPipe canonical face model, registered to the skull at paired levels using published adult male soft-tissue thicknesses. Landmarks derived from the geometry itself; the foramina, artery courses and ligament positions placed from the measurements cited on each.

What this atlas does not show

Entry points, landmark constructions, volumes, instruments and the routing of each read to each point. Those are the Masterclass. What is here is the architecture: what is read, where each step works, in which plane, and what stops it.

Method

How the atlas was made

The reference skeleton is loaded as its actual triangle meshes, one per structure, so what you spin is the bone itself, not a picture of it. The soft-tissue surface is a canonical face registered to that skull at published thicknesses. Every overlay is constructed in millimetres from landmarks derived from the geometry and projected nowhere: it sits in the same space as the bone. Full method on the sources page.

Scale

Real millimetres

This reference skull measures 128 mm across the zygomatic arches and 77 mm across the mandibular angles on bone; the surface carries the published soft-tissue thicknesses on top. Distances quoted in the detail panel are from the cited studies, not from this model.

Limits

One reference, not every man

A single reference individual cannot show variation. Vessel courses are schematic paths through measured waypoints; depth relative to the mimetic muscles varies by region and by person, which is exactly why the Codex keeps its structural steps on bone and its superficial step blunt and slow.
