ETFE气枕顶棚：充气枕面与细钢网格

Design an urban canopy made of inflated transparent cushions. Show a shallow vaulted roof divided into a grid of hexagonal cells, each cell filled by a pillow of ETFE film inflated into a gentle dome above and a shallow curve below, so the whole surface reads as a field of soft transparent bubbles rather than as a flat sheet. Detail the frame as a fine white steel lattice following the hexagon edges, its members slim and its nodes cast as small white discs, with the aluminium clamping profiles holding each cushion's edge visible as a thin bright line. Show the film as almost fully transparent with a printed silver dot pattern on the middle layer, dense at the cushion centres and thinning at the edges, so the sky reads clearly through the perimeter of each cell and is veiled at its middle. Detail the small air supply ducts running discreetly along the frame. Show the shadow beneath as a soft hexagonal mottle rather than a hard pattern. Set it over a paved plaza between contemporary buildings with people crossing. Show bright blue sky above and diffuse light below. Photorealistic, translucent, white frame against blue, upward view into the cushions.
