O'Neill Cylinder — Rotating Ring Habitat
A torus-shaped space station spins about its central axis to generate artificial gravity via centrifugal force, letting inhabitants stand on the inner hull as if it were ground. A cutaway wedge exposes the interior buildings, floor, and window lighting.
- Ring habitat: major radius 60, tube radius 16, spun continuously
- 6 structural spokes connect the ring to a central docking hub
- 90 instanced buildings and 200 instanced glowing windows line the interior
- Cutaway geometry (72% of torus) reveals the inhabited interior
