Projection mapping 光雕投影

video

Warping projected content to fit a non-flat, non-rectangular surface: a building facade, a set piece, a car. The content is authored against a model of the object, and the projector is aligned to that model on site.

中文

把投影內容變形以貼合非平面、非矩形的表面：建築外牆、景片、車輛等。內容依物件模型製作，現場再把投影機對位到該模型。
