我加载一个 .obj 文件：

var loader = new THREE.OBJMTLLoader();
loader.load( "../obj/machine.obj", '../obj/machine.mtl',  this.loadObject);

并尝试检测对其的点击：

 click: function(event){
        this.mouse.x = ( event.clientX / window.innerWidth ) * 2 - 1;
        this.mouse.y = - ( event.clientY / window.innerHeight ) * 2 + 1;
        var vector = new THREE.Vector3( this.mouse.x, this.mouse.y, 1 ).unproject( this.camera );
        this.raycaster.set( this.camera.position, vector.sub( this.camera.position ).normalize() );

        console.log(this.scene.children);
        var intersects = this.raycaster.intersectObjects( this.scene.children );

        if ( intersects.length > 0 ) {

            console.log("hitting something");

        }
    },

这在网格上效果很好，但在加载的 3DObject 上效果不佳，因为它在 this.scene.childeren 中可见：
