How the movement works
To show a long stretch of time, or how a city, sky or task changes, in a short clip.
- 01Camera: completely fixed (height 1.6 m, pitch +0.08 rad, about 5° up)
- 02Timing: 12 hours pass in 3.7 s (0.4 s to 4.1 s), cubic ease-in-out (about cubic-bezier(0.65,0,0.35,1))
- 03Sun: travels left to right along an arc, angle a = -1.25 rad → +1.25 rad; position (sin a×120, cos a×60 - 8) m at 170 m depth
- 04Three clouds drift 140 m to the right in total, wrapping every 80 m; seven small figures each cross an 18 m width 6 times (odd and even ones in opposite directions)
- 05Building shadows fall away from the sun and swing as it moves (translucent grey)
- 06Return: cross-fade back to the start over the last 0.5 s; the top-right clock runs 06:00 → 18:00 in 10-minute steps
Prompt
Time-lapse of the city from dusk to night as the lights come on.
