Discus Cage

A U of six galvanised masts 5m tall on a concrete pad carrying a hung safety net that sags between them and swings as one skin in the wind, two swinging gate wings at the mouth on real hinges, and a throwing circle with a steel rim set into the pad.

风格：low-poly, flat-shaded vertex colors, no textures, 2 materials: the shared opaque one plus a distinct surface (glass, water or chrome), which stays its own mesh through mergeAssets rather than merging into the rest; shares palette and scale with its kit
