# World Run — Tokyo sky life

The original cartoon gull-like bird was authored in Higgsfield 3D Jutsu,
project `e5a2eac4-fad0-4a2d-8e81-511349a2c950`, committed revision 1,
on 2026-09-13. Project: https://higgsfield.ai/3d-jutsu/e5a2eac4-fad0-4a2d-8e81-511349a2c950

`bird.glb` is the local portable derivative: body and two independently
pivoting wings, with original material colors baked into vertex colors.
It contains 3,835 triangles in three batches and no external textures.
Forward is +X, wing hinges rotate around X, and units are metres.
Source construction and the inspected Eevee preview are retained under
`work/tokyo-sky/`; the runtime animates flapping, gliding, banking and formations.
This is a stylized bird, not a surveyed species identification.

Airliners reuse only the moving jet geometry from the existing Narita
airport model in `assets/tokyo-transit/narita-airport.glb`; see that folder's
PROVENANCE.md for its source. No aircraft texture or second airport download
is added. The original fictional blue-and-white livery remains unchanged.

Cruise circuits and the compact approach, flare, landing, rollout and apron
taxi route are authored game animation. They do not reproduce real flight
paths, operating speeds, Narita runway dimensions or procedures.
