张力膜下的无柱空间：缆网屋顶的公共室内

Design an open interior inspired by Frei Otto. Create large column-free spaces beneath tensile membranes and cable-net roofs where natural daylight, ventilation, and lightweight structural systems define the experience. Express structural efficiency through visible tension members, elegant engineering, and uninterrupted public gathering spaces. A vast hall beneath a translucent membrane stretched over a fine steel cable net, the net's saddle curvature clearly readable overhead, slender masts and radiating guy cables at the perimeter, daylight arriving evenly through the membrane with no glare, a plain paved floor and scattered seating, soft diffuse light, wide upward view, 24mm lens, interior photography, ultra photorealistic, 8K
