three.js 加载 obj模型

function loadObj(){
            var loader = new OBJLoader();

            loader.load( ‘./3d/banana.obj‘, function ( obj ) {
                let object = obj;
                
                object.scale.set(3,3,3);
                object.children[0].material.color.set(0xe8b73b);
                object.rotation.x = 1;
                object.rotation.y = 0.3;
                scene.add(object);
            });

            var light = new THREE.DirectionalLight(0xffffff);//光源颜色
            light.position.set(20, 10, 1305);//光源位置
            scene.add(light);//光源添加到场景中
