// MIDNIGHT METROPOLIS — a realistic night city flown over by a slow
|
|
// banking camera. The whole city is one static mesh; every lit window is
|
|
// pixel math on the facade uv (baked in window units), and each beat a
|
|
// fraction of the windows re-roll their state: hash(tower, window,
|
|
// floor(beat)) — the city itself flickers in tempo. Rooftop beacons blink
|
|
// on tall towers, and the tiltshift stage turns the blocks into a
|
|
// miniature. Pattern taught: the city engine's camera is engine-authored
|
|
// (a Lissajous drift with view-space banking) — cam_* keys don't steer it,
|
|
// `alt`/`fly`/`bank` do.
|
|
//
|
|
// SCALE: `blocks` is the DEPTH dial. The drift radius, the look-ahead, the
|
|
// ground and the sky all scale with the city's half-extent, so raising the
|
|
// block count at a FIXED `block` pitch keeps the near field exactly as it
|
|
// framed and adds rows RECEDING TO THE HORIZON — 18 blocks is ~1060 towers,
|
|
// four times the old nine-block cluster, and the fog is thinned to match so
|
|
// the far rows read as a dim glittering skyline instead of being eaten.
