// 假设使用Three.js和TensorFlow.js进行人脸识别和妆容应用
import * as THREE from 'three';
import * as tf from '@tensorflow/tfjs-node';

// 加载模型和纹理
const faceMesh = await loadFaceMeshModel();
const lipstickTexture = await loadTexture('lipstick.png');

// 处理上传的照片
const image = new Image();
image.src = 'user_uploaded_photo.jpg';
image.onload = () => {
    const canvas = document.createElement('canvas');
    const context = canvas.getContext('2d');
    canvas.width = image.width;
    canvas.height = image.height;
    context.drawImage(image, 0, 0);

    // 使用TensorFlow.js进行人脸检测
    const predictions = await detectFaces(context);

    // 应用妆容效果
    for (const prediction of predictions) {
        const faceMeshInstance = faceMesh.clone();
        faceMeshInstance.position.set(prediction.x, prediction.y, prediction.z);
        faceMeshInstance.material.map = lipstickTexture;
        scene.add(faceMeshInstance);
    }

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