效果演示：

使用介绍：

主要代码如下：

(function () {
    // Set up the scene, camera, and renderer
    const scene = new THREE.Scene();
    const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
    const renderer = new THREE.WebGLRenderer();
    renderer.setSize(window.innerWidth, window.innerHeight);
    document.body.appendChild(renderer.domElement);

    // Create a cube geometry and material
    const geometry = new THREE.BoxGeometry(1, 1, 1);
    const material = new THREE.MeshBasicMaterial({color: 0xffffff, vertexColors: THREE.FaceColors});
    const cube = new THREE.Mesh(geometry, material);
    scene.add(cube);

    // Define colors for each face of the cube
    const colors = [0xff0000, 0x00ff00, 0x0000ff, 0xffff00, 0xff00ff, 0x00ffff];
    let faces = cube.geometry.faces;
    if (faces && faces.length) {
        faces.forEach((f, index) => {
            f.color.setHex(colors[index % (colors.length)]);
        });
    }

    // Position the camera
    camera.position.z = 5;

    // Animation function
    function animate() {
        requestAnimationFrame(animate);
        cube.rotation.x += 0.01;
        cube.rotation.y += 0.01;
        renderer.render(scene, camera);
    }

    // Start the animation
    animate();
})();
