A 3D terrain map of a game world is rendered as an interactive, rotating surface. A heightmap drives vertex displacement, with multiple textures such as ocean, sand, grass, rock, and snow blended via a custom GLSL shader based on elevation. The visualization uses Three.js with WebGL rendering, OrbitControls for camera navigation, and D3 for CSV data loading. The scene includes a point light, a semi-transparent water plane, and a checkerboard ground, all presented at five times standard pixel density for clarity on high-DPI displays.
