Check out the OBJLoader usage sample at https://github.com/mrdoob/three.js/blob/master/examples/webgl_loader_obj.html#L75
在https://github.com/mrdoob/three.js/blob/master/examples/webgl_loader_obj.html#L75查看 OBJLoader 使用示例
(In action http://mrdoob.github.com/three.js/examples/webgl_loader_obj.html)
（在行动http://mrdoob.github.com/three.js/examples/webgl_loader_obj.html）
var loader = new THREE.OBJLoader();
loader.load( objURL, function ( object ) {
scene.add( object );
} );

Try adding a light into the scene or just assign the Obj a MeshBasicMaterial to see its shape:
尝试在场景中添加一盏灯，或者只为 Obj 指定一个 MeshBasicMaterial 以查看其形状：
var objLoader = new THREE.OBJLoader();
var material = new THREE.MeshBasicMaterial({color: 'yellow', side: THREE.DoubleSide});
objLoader.load('file.obj', function (obj) {
obj.traverse(function (child) {
if (child instanceof THREE.Mesh) {
child.material = material;
}
});
scene.add(obj);
});
Then you are able to see that the model has actually already been loaded. If not, try adjusting the position of your camera.
然后你就可以看到模型实际上已经被加载了。如果没有，请尝试调整相机的位置。
The documentation has left out the light so that it seems quite confusing at this point for beginners including me. :)
文档忽略了这一点，因此对于包括我在内的初学者来说，此时似乎很困惑。:)
