座席ビュー付きのインタラクティブ3Dサッカースタジアム販売サイト

Build a single-page ticketing website around an interactive 3D football stadium. Use a dark navy interface with blue accents: a top navigation bar, a match header with two team flags, and a side panel that shows the selected section, seat and price with a checkout button. In the main view render a full stadium bowl with a green pitch, tiers of colour-coded seating sections, floodlights and a roof ring. Let visitors orbit and zoom the camera, click a section to highlight it, and switch to a first-person seat view that shows the pitch and crowd from that seat. Add camera controls and view toggles at the bottom. Use Three.js with procedurally generated geometry. Done means the stadium is smooth to navigate, sections are selectable, the seat view works, and the side panel updates with each choice.
