This is a true closed 3D mesh built from 4 silhouettes and a rounded shape prior. The four images are projected and blended over the mesh so the viewer can rotate continuously through 360°.
Intermediate geometry is estimated, not an accurate photogrammetric scan. Four photos use different arm poses, and unseen concavities remain uncertain.
Processing is local. The browser render loads deterministic geometry and source projections rather than a generated identity or unknown full-photo model.
