我开始使用THREE.js,我正在尝试绘制一个带有纹理的矩形,由单个光源照亮.我认为这很简单(为简洁起见省略了HTML):

function loadScene() {
    var world = document.getElementById('world'),
        WIDTH = 1200,
        HEIGHT = 500,
        VIEW_ANGLE = 45,
        ASPECT = WIDTH / HEIGHT,
        NEAR = 0.1,
        FAR = 10000,

        renderer = new THREE.WebGLRenderer(),
        camera = new THREE.Camera(VIEW_ANGLE, ASPECT, NEAR, FAR),
        scene = new THREE.Scene(),
        texture = THREE.ImageUtils.loadTexture('crate.gif'),
        material = new THREE.MeshBasicMaterial({map: texture}),
        // material = new THREE.MeshPhongMaterial({color: 0xCC0000});
        geometry = new THREE.PlaneGeometry(100, 100),
        mesh = new THREE.Mesh(geometry, material),
        pointLight = new THREE.PointLight(0xFFFFFF);

    camera.position.z = 200;    
    renderer.setSize(WIDTH, HEIGHT);
    scene.addChild(mesh);
    world.appendChild(renderer.domElement);
    pointLight.position.x = …
