用 Three.js 构建的实时 3D 喷气飞机工厂模拟

Build a live 3D simulation of a small jet aircraft factory that runs in the browser with Three.js. Show a large pale factory floor with several parallel assembly lines, overhead gantry cranes in orange, workstation benches, parts racks, and partly assembled white jets moving from station to station. Use a clean, light palette with blue and orange accents and soft daylight. Add tiny worker figures that walk between stations and a runway outside where finished jets appear. Provide orbit camera controls with zoom and pan, and a small on-screen toolbar for switching views and toggling layers. Base the layout on lean production principles: a clear one-directional flow from raw parts to final assembly to delivery. Deliver a deployable web page, test that it loads without errors, and consider the task done when the moving plant can be viewed from above and up close without glitches.
