歩き回れる夜のホグワーツ風城シーンをThree.jsで作成

Build an explorable 3D fantasy castle scene at night for the browser. Create a large gothic school-of-magic castle on a cliff above a lake, with many pointed towers, lit windows, stone walls, a long covered bridge, a courtyard with paving, a wooden staircase hall with brick walls and a room with floating candles. Use a dark blue night palette, a full moon, drifting fog and warm window glow for contrast. Let the viewer move freely with first-person controls and mouse look, passing from the exterior views through the bridge and into the interiors. Add simple labels naming key locations. Use Three.js, procedural geometry and basic lighting, delivered as a runnable web project. It is done when the castle reads clearly from far away, the interiors are reachable, and the night mood stays consistent throughout the walkthrough.
