使用threejs加载模型，页面空白

在vue3项目中使用threejs加载3D模型，页面始终空白，无报错。

运行项目后，可以看到场景对象、相机对象、加载器对象、模型对象均可以正确打印，且无报错。但是页面始终空白，已确认过模型没有问题，也试过换模型，页面都是空白，尝试旋转场景，也无法展示模型。

vue是世界上最好的语言。

这光定义了渲染器跟相机，但是没有调用渲染函数吧
function animate() {

            requestAnimationFrame( animate );
            renderer.render( scene, camera );

}
