/**
 * Creates a cube texture made up of six images.
 * @remarks
 * {@link CubeTexture} is almost equivalent in functionality and usage to {@link Texture}.
 * The only differences are that the images are an array of _6_ images as opposed to a single image,
 * and the mapping options are {@link THREE.CubeReflectionMapping} (default) or {@link THREE.CubeRefractionMapping}
 * @example
 * ```typescript
 * const loader = new THREE.CubeTextureLoader();
 * loader.setPath('textures/cube/pisa/');
 * const textureCube = loader.load(['px.png', 'nx.png', 'py.png', 'ny.png', 'pz.png', 'nz.png']);
 * const material = new THREE.MeshBasicMaterial({
 *     color: 0xffffff,
 *     envMap: textureCube
 * });
 * ```
 * @see {@link https://threejs.org/docs/index.html#api/en/textures/CubeTexture | Official Documentation}
