Three.js在场景的左侧和右侧移动摄影机

// 创建场景
var scene = new THREE.Scene();

// 创建透视摄像机
var camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);

// 设置摄像机位置和目标点
camera.position.z = 5;

// 创建渲染器
var renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

// 创建一个立方体
var geometry = new THREE.BoxGeometry();
var material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
var cube = new THREE.Mesh(geometry, material);
scene.add(cube);

// 动画循环
function animate() {
    requestAnimationFrame(animate);

    // 移动摄像机到左侧
    camera.position.x = -2;

    // 或者移动摄像机到右侧
    // camera.position.x = 2;

    // 渲染场景
    renderer.render(scene, camera);
}
animate();
