室内瀑布与森林谷：玻璃钢构穹顶下的地景

Design an indoor valley in the manner of Moshe Safdie under a vast toroidal glass and steel dome, with water falling forty metres through a circular oculus at the centre into a terraced forest below. Compose the diagrid shell curving overhead in a doughnut form, the cylindrical waterfall backlit and misting, spiralling planted terraces of tree ferns and palms, walkways threading through the canopy, soft daylight diffused through the glass, low view up the falls, 24mm lens, landscape architecture photography, ultra photorealistic, 8K
