Thank you,

Base gemotery was derived from BodyParts3D, where the meshes were optimized.

Nerves and vesseles mostly follow data from Z-Anatomy

Internal tooth anatomy was modeled inside the actual tooth rather than coming from one complete premade GLTF

Three.js loads and renders those GLBs and handles interactions,materials,camera controls etc.

Hope this makes sense, if you want to know more there are proper sources of assets on the repo :)
