The source model is the BodyParts3D 4.0 `FMA13478` vertebral-column compound: 24 vertebrae (`FJ3154`–`FJ3177`), 23 intervertebral discs (`FJ3202`–`FJ3224`), and the sacrum (`FJ3393`). The parts were combined, reoriented, simplified, and Meshopt-compressed for interactive web display. The WebP is an 18-second, 180-frame transparent render of that adapted model for privacy-focused browsers that disable WebGL. No texture data is included.
