about

nx_bodyatlas.nx -- ★HOLISTIC ANATOMICAL BEING (operator 2026-07-10, ref zygotebody.com + sloyd.ai/3d-human-model-generator): "we are doing humans... generate holistic beings with parts". A whole-body human generated procedurally with ALL of its anatomical SYSTEMS present as independently peelable layers -- exactly ZygoteBody's peel-a-layer atlas, and Sloyd's parametric body generator, but 100% integer + sovereign (own SDF + integer ortho ray-march, no ML/Blender/externals). 8 SYSTEMS (bit in the visibility mask): 0 SKIN 1 MUSCLE 2 SKELETON 3 DIGESTIVE 4 CIRCULATORY 5 RESPIRATORY 6 URINARY 7 NERVOUS ~77 parts / ~60 NAMED structures head-to-toe (skull..foot; heart,lungs,liver,kidneys,brain,spinal cord,...). PARAMETRIC (Sloyd-style): height / girth / frame-width / sex presets reshape the whole being from one seed. PEEL (ZygoteBody-style): render with any subset of systems visible -> strip skin to see muscle, strip muscle to see skeleton + viscera, isolate one system. Each part carries a system id + a name id -> the atlas can name parts. This extends the layered idea in nx_anatstack (bone->muscle->fat->skin peel) from the FACE to the WHOLE BEING and from tissue layers to full anatomical SYSTEMS. license_tier: ORIGINAL
