用 Three.js 制作的 Hyperloop 胶囊模拟器与实时速度面板

Build an interactive Hyperloop demo web page with Three.js. Show a sleek capsule pod travelling along an elevated tube track on concrete pylons, in a pale, minimal studio setting with soft fog and a muted palette accented by a single red highlight. Place a large Hyperloop headline and short intro text on the left, and a side control panel on the right with a live speed readout in km/h and several dropdown options for the view and the pod configuration. Add a bottom bar with a pause button, a progress slider and a numeric value. The pod should accelerate smoothly while the readout climbs, and the camera should drift along the track so the scene feels cinematic. Deliver a single page that runs in the browser, with responsive layout and clean typography. Done when the pod animates continuously, the speed counter matches the motion, and the controls change what is displayed.
