樹状鋼柱林：枝分かれした幹が支える葉状キャノピー

Design an urban canopy carried on branching tree columns. Show a field of slender steel trunks rising from the paving and splitting three times as they climb — one trunk into three limbs, each limb into three thinner branches — until the tips form a dense regular field of support points about seven metres up, so the canopy above needs almost no depth. Detail the branches as tapered circular hollow sections, each thinner than the one below it, welded at the forks and ground smooth so the joints disappear and the growth reads as continuous. Show the roof they carry as a shallow surface of small hexagonal panels, each panel a slightly translucent white composite, the panels leaving fine gaps between them so daylight enters as a scattered dapple. Detail the whole assembly in one pale off-white finish, trunks and canopy alike, so the structure reads as a single organism. Show the shadow on the paving as a soft mottled pattern much like light under real foliage. Set it over a pedestrian street between mid-rise buildings, with people walking through the trunks. Show bright hazy daylight. Photorealistic, arboreal, white on grey paving, eye-level view down the colonnade.
