three.js 物体位置

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

// 创建相机
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
camera.position.z = 5;

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

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

// 设置立方体的位置
cube.position.set(1, 2, 3); // x, y, z 坐标

// 将立方体添加到场景中
scene.add(cube);

// 渲染循环
function animate() {
    requestAnimationFrame(animate);
    cube.rotation.x += 0.01;
    cube.rotation.y += 0.01;
    renderer.render(scene, camera);
}
animate();

const parentObject = new THREE.Object3D();
parentObject.position.set(0, 0, 0);
scene.add(parentObject);

parentObject.add(cube);
cube.position.set(1, 2, 3); // 相对于父物体的位置
