如何仅使用脚本在three.js / editor中更改摄像头？

var camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
camera.position.set(0, 0, 5);
camera.lookAt(0, 0, 0);

scene.add(camera);

var controls = new THREE.OrbitControls(camera, renderer.domElement);

function animate() {
    requestAnimationFrame(animate);
    controls.update();
    renderer.render(scene, camera);
}
animate();
