airport terminal 3d model

Create a simplified central airport terminal hub inspired by Beijing Daxing International Airport, not an exact replica, for a Unity airport drone intrusion and LiDAR simulation demo. Game-ready GLB asset with modeling and textures included. Focus only on the main central terminal building: a large rounded central hall, compact radial layout, flowing organic roof, soft curved roof edges, linear skylight strips, blue-tinted glass curtain walls, dark window frames, light gray concrete and metal structure, and a clean futuristic international airport style. The building should feel grand, modern, elegant, and clearly airport-like, with solid 3D volume, not a flat facade or thin shell. Medium detail, optimized mesh, real-time rendering friendly. Use realistic PBR textures: light gray concrete, brushed metal, blue-gray glass, dark frames, subtle clean wear. No cars, no aircraft, no people, no logo, no text, no watermark, no background.
