インドアクライミングジム：立体的な壁とルートカラー

Render the interior of an indoor climbing centre. Show a complex three-dimensional wall structure filling a tall volume — plywood panels in varying planes forming slabs, vertical faces, overhangs, a steep roof section and a rounded volume, all finished in textured resin in muted greys and dark tones so the holds read against them. Detail hundreds of bolt-on holds screwed into a grid of threaded inserts, grouped into routes by colour with small numbered tags at each start, the colours saturated against the neutral wall. Show the bouldering area's floor as thick continuous safety matting in dark grey, seamless and slightly compressed near the busiest sections, with a raised timber edge. Detail the roped section with auto-belay devices at the top and rope ends hanging. Show the exposed steel structure and services overhead, painted black, with directional lighting aimed at the wall faces rather than down. Include benches, shoe racks, a chalk bucket and climbers resting. Photorealistic, tall, dark walls with bright hold colours, eye-level view.
