Projection Mapping: Facades as Screens

At night, the facade of a building is completely covered by a large projection, with the image precisely aligned to every window, column, and molding, making it appear not as a projection on the wall but as if the building itself is transforming—walls cracking, bricks scattering, towers growing taller. The projectors are hidden in the rooftops of opposing buildings and in ground-level landscaping, with several light beams visible piercing through the thin night mist. All ambient lighting around the building is turned off, leaving only the light from the projection. In the foreground are silhouettes of people looking up. Avoid: the image not aligning with the actual contours of the building, surrounding streetlights still being on, the projector bodies being visible, the image being a flat pattern rather than a three-dimensional transformation.

夜間,一座建築的立面被大型投影完全覆蓋,影像精準對位到每一個窗、每一根柱與每一道線腳,因此看起來不是投影在牆上而是建築本身在變形——牆面裂開、磚塊飛散、塔樓長高。投影機藏在對面建築的屋頂與地面的造景裡,看得見幾道光柱穿過夜間的薄霧。建築周邊的環境照明全部關閉,只剩投影的光。前景是仰頭觀看的人群剪影。避免:影像沒有對位到建築的實際輪廓、周邊路燈仍然亮著、看得見投影機本體、影像做成平面的圖案而非立體變形。
