自然结构的几何:悬链拱与倾斜柱

Design a building in the manner of Antoni Gaudí whose structure derives entirely from hanging-chain form-finding, so that every arch follows a pure catenary and every column leans along its exact line of thrust, eliminating the need for flying buttresses. Compose leaning stone and brick piers branching like trees toward a ribbed vault, parabolic arches of differing span, no vertical column anywhere in the composition, rough-hewn local stone with visible tool marks, warm low sun raking across the leaning geometry, upward eye-level view, 24mm lens, architectural photography, ultra photorealistic, 8K
