在three.js中倾斜摄影机时，光线投影器会置换对象交点

// 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);

// 设置相机位置
camera.position.z = 5;

// 创建光线投影器
const raycaster = new THREE.Raycaster();
const mouse = new THREE.Vector2();

function onMouseMove(event) {
    // 将鼠标位置归一化到[-1, 1]范围内
    mouse.x = (event.clientX / window.innerWidth) * 2 - 1;
    mouse.y = -(event.clientY / window.innerHeight) * 2 + 1;

    // 更新光线投影器的方向向量
    raycaster.setFromCamera(mouse, camera);

    // 检测光线与场景中物体的交点
    const intersects = raycaster.intersectObjects(scene.children);

    if (intersects.length > 0) {
        console.log('Intersection detected:', intersects[0]);
    }
}

window.addEventListener('mousemove', onMouseMove, false);

// 渲染循环
function animate() {
    requestAnimationFrame(animate);
    renderer.render(scene, camera);
}

animate();
