如何在three.js中移动相机位置的同时保持相机旋转指向原点？

var camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
camera.position.set(0, 0, 10);
camera.lookAt(0, 0, 0);

var controls = new THREE.OrbitControls(camera);
controls.update();

function animate() {
    requestAnimationFrame(animate);
    
    // 更新相机和控制器
    controls.update();
    
    // 渲染场景
    renderer.render(scene, camera);
}
animate();

camera.position.set(x, y, z);

camera.lookAt(0, 0, 0);
