発射台10基のロケット工場を再現したThree.js 3Dシミュレーション

Build a live 3D factory simulation in Three.js that runs in the browser. Model a rocket production site with a large assembly hall, an internal production line with stations, a road network, a river and landscaped terrain, plus ten launch pads with gantry towers laid out along a strip of land. Animate the full flow: raw materials arrive, rockets are assembled inside the hall, each finished rocket drives out on a transporter to a free pad, stands upright and lifts off with a short exhaust effect. Use a clean, light palette with white buildings, soft green ground and pale blue water. Add an orbit camera so the viewer can fly from an overview of all pads to a close look inside the hall, and a small HUD with a clock and speed control. Apply lean-production ideas such as a steady pull flow and minimal waiting. Deliver one self-contained HTML file. Done means rockets are produced, dispatched and launched continuously without manual input.
