纸管网壳展厅室内：外露接头与无柱空间

Design an exhibition hall inspired by the Japanese Pavilion at Expo 2000. Use a continuous paper tube gridshell spanning a column-free space, filtered daylight through translucent membranes, exposed structural joints, and flexible exhibition layouts. Emphasize openness, structural clarity, and lightweight construction. A long tunnel-vaulted hall formed from a diagonal grid of cardboard tubes tied with fabric tape at every crossing, a translucent paper membrane stretched over the grid glowing softly, a plain timber deck floor, no internal columns, warm diffuse daylight through the paper, one-point perspective down the vault, 24mm lens, interior photography, ultra photorealistic, 8K
