three.js 坐标系原点

// 确保对象的本地坐标系正确
object.position.set(x, y, z);

// 检查变换矩阵是否正确应用
object.updateMatrixWorld();

// 设置相机的位置和目标点
camera.position.set(x, y, z);
camera.lookAt(new THREE.Vector3(targetX, targetY, targetZ));

// 使用四元数进行旋转，避免万向节锁问题
object.quaternion.setFromAxisAngle(axis, angle);

// 创建场景、相机和渲染器
const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
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);
scene.add(cube);

// 设置相机的位置
camera.position.z = 5;

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