OptoGuide preserves all 2,234 meshes and 3,432 concepts, with unchanged geometry buffers.
We adapted the interface, asset paths, camera handling and links into ocular teaching models. Runtime display-system corrections classify brain ventricles/choroid plexus as nervous, wrist flexor retinacula as connective tissue and lacrimal bones as skeletal; the original anatomical records and geometry remain unchanged.
This is an adult male reference with incomplete coverage of anatomical variation.

2026-09-28: OptoGuide added an original study workspace with dedicated model, system and inspection areas, body/neural/ocular study starting points, and direct Study hub collection links. Camera framing was adapted to the unobstructed stage. These interface changes do not alter the credited source geometry or imply endorsement by the original authors.

2026-09-28: Brain teaching adaptation expands the runtime Brain selection from 59 to 85 existing meshes, including omitted deep structures, white matter, CSF connections and visual landmarks. Seven OptoGuide study views and a labelled teaching-colour palette expose these structures; source asset records, names, identifiers and geometry buffers remain unchanged. Structure notes and evidence links are original OptoGuide additions, with clinical review pending.

2026-09-28: Whole-body teaching pass adds 57 sourced notes, 24 organ views, grouped part selection and explicit geometry limits. Runtime system corrections now total 54 (43 additional muscle, connective-tissue, oral, nasal and liver-tissue entries). The heart selection also includes its supplied ventricular wall. Heart cavity/valve colours are labelled teaching colours, not oxygenation. All source meshes and identifiers remain unchanged.

2026-09-28: Small-structure teaching adds 48 further original notes (105 body notes total) and six hand views (30 views total). Runtime hand selections restore eight existing carpals per side, without altering source geometry. Dated editorial source checks are distinct from independent clinical certification; detailed limits remain visible.
