A 4×4×4 cube of 64 color-coded spheres rotates slowly in 3D space, demonstrating a lattice-like arrangement of electrons or atoms. Built with Three.js, the scene uses a WebGL renderer and OrbitControls for interactive camera rotation and zoom. Each sphere’s hue is derived from its grid position via HSL color mapping, with directional and ambient lighting illuminating the structure. The animation loop continuously rotates the entire group while the camera remains user-controllable.
