This 3D scene shows a modern urban central business district built along a linear urban river channel, integrating office skyscraper clusters, ecological revetment landscape, pedestrian waterfront green belts and urban pedestrian arch bridges. The river adopts natural rippling water surface material; both banks are equipped with rubble retaining walls, white safety railings, layered native lawns, flowering shrubs, weeping willows and cherry blossom trees to form a continuous ecological green corridor. On both sides stand various modern glass curtain wall office towers with different heights and shapes, matching a small number of existing mid-rise residential buildings to reflect the integration of new business districts and old urban areas. The middle of the river is spanned by a three-span concrete pedestrian arch bridge, connecting the two sides of the waterfront pedestrian system. The whole scene adopts bright daylight rendering atmosphere, suitable for urban river regulation planning reporting, waterfront CBD landscape design bidding, sponge city ecological renovation demonstration, urban renewal project presentation and municipal landscape engineering display.
