3d head model

3D human head model for gaze estimation experiments. Features a "two-sphere" eye construction based on ophthalmological standards. The eye assembly consists of a primary scleral sphere and a secondary protruding corneal sphere. The model must allow for clear differentiation between the eyeball center (Oe) and the cornea center (Oc) to simulate the optical axis. Include a well-defined 3D iris and pupil disc. The head mesh should have realistic eye sockets (orbits) that allow the eyeball assembly to rotate freely. 8K textures, PBR materials, watertight mesh, render-ready for Blender or Octane. The assest is just head and not full body.
