Petal-like Cathedral: Hyperbolic Paraboloid Ribs and Stained Glass

Design a cathedral interior in the manner of Oscar Niemeyer entered through a dark underground passage and released into a circular hall enclosed by sixteen curved concrete ribs that open like flower petals, with stained glass filling every gap between them. Compose sixteen white hyperboloid ribs sweeping up and outward, vast panels of blue, green and white stained glass between them flooding the room with coloured light, a plain circular floor, suspended angel figures hanging in the void, brilliant filtered colour light with no visible fixture, wide upward view from the centre, 24mm lens, interior photography, ultra photorealistic, 8K
