The structure features horizontal ribbed bands wrapping each tower and a low, rounded base with illuminated windows. At 0.2 seconds, the sky is bright blue with wispy white clouds; by 1.0 second, clouds streak faster, deepening to indigo. By 2.0 seconds, ambient light dims, casting warm golden highlights on the facade as dusk settles. At 3.0 seconds, the sky turns dramatic amber and violet, with strong directional lighting accentuating the building’s contours; interior lights begin glowing faintly. By 4.0 seconds, full night arrives: the sky is dark with soft cloud trails, the building’s ribbed edges emit cool white LED strips, and the base glows warmly from within, reflecting subtly on the smooth pavement below. The camera remains static throughout, capturing the time-lapse transition from day to night. HY15BuildingYanshi, The Oriental Pearl Tower dominates the Shanghai skyline against a clear blue sky, flanked by modern skyscrapers and reflected in calm water below. At 0.2 seconds, the scene is brightly lit by daylight; a small cloud drifts leftward behind the tower. By 1.0 second, lighting remains unchanged, with the tower’s metallic spheres and spire sharply defined. At 2.0 seconds, ambient light dims as dusk begins; red illumination activates on the tower’s upper sphere and vertical segments, casting vivid red reflections on the water. By 3.0 seconds, the sky deepens to indigo, city lights ignite across surrounding buildings, and the tower glows intensely red and gold. At 4.0 seconds, full night has settled: the tower’s lights remain vibrant, windows of adjacent high-rises shine warmly, and the water mirrors streaks of red and yellow light. The camera remains static throughout, capturing the seamless transition from day to night.
