如何将图像放入 Three.js 纹理

Question

我试图将纹理放入 Three.js 对象中，但是当我应用图像时，对象全黑了。一些警报显示在代码上但没有错误。上图显示结果。有什么建议吗？

       var loader = new THREE.ImageLoader();

            var camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);

            var renderer = new THREE.WebGLRenderer();

            var cube = new THREE.Mesh(cubegeometry, cubematerial);



            //segundo objeto 
            var texture = THREE.ImageUtils.loadTexture('wood.jpg');
            var cbmaterial = new THREE.MeshPhongMaterial({map: texture});
            var cbgeometry = new THREE.CubeGeometry(5.05,0.5,3.75);

            var cb = new THREE.Mesh(cbgeometry, cbmaterial);



            scene.add(cube);
            scene.add(cb);
            camera.position.z = 6

            var render = function(){
                requestAnimationFrame(render);

                cube.rotation.y += 0.02;
                cube.rotation.x += 0.01;
                cube.rotation.z += 0.00;

如果场景中没有任何灯光，那可能就是问题所在。至少添加一些环境光。例如：

var ambient = new THREE.AmbientLight( 0x555555 );
scene.add( ambient );
