使用ThreeJS在3D模型上添加2D图像点击点

<script src="https://cdnjs.cloudflare.com/ajax/libs/three.js/110/three.min.js"></script>

var scene = new THREE.Scene();
var renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

var geometry = new THREE.BoxGeometry(1, 1, 1);
var material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
var cube = new THREE.Mesh(geometry, material);
scene.add(cube);

var spriteMap = new THREE.TextureLoader().load('path/to/image.png');
var spriteMaterial = new THREE.SpriteMaterial({ map: spriteMap });
var sprite = new THREE.Sprite(spriteMaterial);
sprite.position.set(1, 1, 1); // 设置2D图像点击点的位置
scene.add(sprite);

function onMouseClick(event) {
    event.preventDefault();
    
    var mouse = new THREE.Vector2();
    mouse.x = (event.clientX / window.innerWidth) * 2 - 1;
    mouse.y = -(event.clientY / window.innerHeight) * 2 + 1;
    
    var raycaster = new THREE.Raycaster();
    raycaster.setFromCamera(mouse, camera);
    
    var intersects = raycaster.intersectObjects(scene.children, true);
    
    if (intersects.length > 0) {
        // 处理点击事件
    }
}

window.addEventListener('click', onMouseClick, false);
