Rigor
The anatomy model
Rigor draws its muscle browser, its injury marker, its layer peel and its Mobility pillar on one 3D model of the human muscular and skeletal systems. That model is an adaptation of open scientific data, it is shared under the same open license, and this page is where anyone can read its sources and take a copy.

The model is derived from Z-Anatomy, which is itself derived from BodyParts3D.
What was changed
The atlas’s muscle meshes were merged into eleven group meshes matching the groups Rigor uses, and its skeletal meshes into one skeleton. Bursae, fasciae, tendon sheaths and internal organs were removed so they do not hide the muscles. The skull was replaced by a blank head shape, so the model carries no face and no likeness of anyone. Every part was simplified to a size a phone can draw, and given a single material that the app recolors as you use it.

The USDZ file is the exact model the app ships. It opens in Apple’s Quick Look and Reality Composer, and in any tool that reads Universal Scene Description.
