球体切分：同一個球面切出所有殼片

Design a shell-roofed building in the manner of Jørn Utzon where every shell, however different in size, is cut from the surface of one single sphere of identical radius, so that all the ribs share one curvature and can be mass-produced. Compose a cluster of white precast concrete shells of differing height rising from a heavy stone platform, the ribs visibly identical in section, the geometry of the common sphere legible in every arc, harbour water around the base, clear morning light with strong shell shadow, low three-quarter view, 24mm lens, architectural photography, ultra photorealistic, 8K
