带城堡、村庄、瀑布和飞艇的体素岛屿场景

Build an explorable voxel island scene featuring a medieval castle. Create a square block of terrain floating in a pale turquoise sea with blocky waves and white voxel clouds. Put a large stone castle with towers and banners at the center, a village of red, teal and blue gabled roofs around it, farm plots, an aqueduct-style wall, a river that ends in a waterfall, a harbor with a small boat, snowy gray mountains and dense voxel pine forests. Add a day-night cycle with lit windows at night, and a small airship drifting overhead. Provide free camera controls to fly above the island and drop to street level or enter buildings, a thin top bar of view presets, an info panel and a minimap in a corner. Use WebGL with instanced cubes for performance and deliver one self-contained HTML file. Done means the island renders smoothly from every camera view and the lighting changes believably.
