教堂的云：折板混凝土天花

Design a church interior in the manner of Jørn Utzon roofed by rolling cast concrete vaults shaped like a bank of cumulus cloud, lit indirectly from concealed clerestories at the crest so no light source is ever visible from the pews. Compose a plain white rectangular hall whose ceiling billows in asymmetric curved slabs, light washing down the inner face of each curve, pale timber pews and floor, undecorated white plaster walls, a simple timber cross, soft graded daylight with no direct sun, wide upward view from the nave, 24mm lens, interior photography, ultra photorealistic, 8K
