A 3D grid of spheres forms a cube, with each sphere’s color derived from its position along the x, y, and z axes using an HSL mapping. The entire cube rotates slowly over time. Built with Three.js, the visualization uses PerspectiveCamera, OrbitControls for user interaction, SphereGeometry, MeshPhongMaterial, and DirectionalLight. The animation loop updates rotation increments and re-renders the scene, while damping controls allow smooth camera zoom and orbit.
