This example displays a three-dimensional cube of spheres, arranged in a 4x4x4 grid, with each sphere’s color determined by its position via an HSL calculation. The entire structure rotates automatically, while users can drag to orbit the view and scroll to zoom, thanks to Three.js’s `OrbitControls`. The scene is built with React 19, which manages the mount point and lifecycle, while Three.js handles WebGL rendering, including `MeshPhongMaterial` for coloring and `DirectionalLight` for illumination.
