实现指南:从API到VR场景的全链路开发

1. 数据层对接(Python/JavaScript)

Mealie API数据转换示例

# mealie_vr_adapter.py
from fastapi import FastAPI
from pydantic import BaseModel
import requests
import asyncio

app = FastAPI()
MEALIE_API = "http://localhost:9000/api/recipes"

class VRRecipe(BaseModel):
    id: str
    name: str
    ingredients: list[dict]
    steps: list[dict]
    spatial_assets: dict  # 新增VR专用字段

@app.get("/vr/recipes/{slug}")
async def get_vr_recipe(slug: str):
    # 获取基础食谱数据
    response = requests.get(f"{MEALIE_API}/{slug}")
    recipe = response.json()
    
    # 转换为VR格式
    vr_recipe = VRRecipe(
        id=recipe["id"],
        name=recipe["name"],
        ingredients=recipe["recipe_ingredient"],
        steps=await enrich_steps_with_spatial_data(recipe["recipe_instructions"]),
        spatial_assets={
            "workspace_layout": "kitchen_standard",
            "ingredient_placement": await calculate_optimal_placement(recipe["recipe_ingredient"])
        }
    )
    return vr_recipe

async def calculate_optimal_placement(ingredients):
    # 基于使用频率和安全距离计算3D摆放位置
    placement = {}
    for idx, ingredient in enumerate(ingredients):
        placement[ingredient["id"]] = {
            "x": (idx % 4) * 0.5,
            "y": 0.8,
            "z": -(idx // 4) * 0.3,
            "rotation": [0, 0, 0]
        }
    return placement

2. 前端VR核心实现(Three.js)

基础场景初始化

// VRSceneInitializer.js
import * as THREE from 'https://cdn.bootcdn.net/ajax/libs/three.js/r150/three.min.js';
import { VRButton } from 'https://cdn.bootcdn.net/ajax/libs/three.js/r150/controls/VRButton.js';
import { OrbitControls } from 'https://cdn.bootcdn.net/ajax/libs/three.js/r150/controls/OrbitControls.js';

class MealieVRScene {
  constructor() {
    this.initScene();
    this.initCamera();
    this.initLights();
    this.initRenderer();
    this.initControls();
    this.loadSpatialAssets();
    this.animate();
  }

  initScene() {
    this.scene = new THREE.Scene();
    this.scene.background = new THREE.Color(0xf0f0f0);
    // 添加厨房基础网格
    const gridHelper = new THREE.GridHelper(10, 20);
    this.scene.add(gridHelper);
  }

  initCamera() {
    this.camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
    this.camera.position.set(0, 1.6, 0); // 模拟人眼高度
  }
  
  // 完整代码见GitHub仓库...
}

// 初始化VR场景
document.addEventListener('DOMContentLoaded', () => {
  const vrScene = new MealieVRScene();
  // 加载食谱数据
  fetch('/vr/recipes/spaghetti-carbonara')
    .then(r => r.json())
    .then(data => vrScene.loadRecipe(data));
});

3. 空间交互系统设计

手势识别核心代码

// GestureController.js
import { XRControllerModelFactory } from 'https://cdn.bootcdn.net/ajax/libs/three.js/r150/controls/XRControllerModelFactory.js';

class RecipeGestureController {
  constructor(scene, camera) {
    this.scene = scene;
    this.camera = camera;
    this.controller1 = renderer.xr.getController(0);
    this.controller2 = renderer.xr.getController(1);
    this.initControllers();
    this.gestureStates = {
      pinch: false,
      grab: false,
      swipe: null,
      tapCount: 0
    };
    this.setupEventListeners();
  }

  initControllers() {
    const controllerModelFactory = new XRControllerModelFactory();
    
    const controllerGrip1 = renderer.xr.getControllerGrip(0);
    controllerGrip1.add(controllerModelFactory.createControllerModel(controllerGrip1));
    
    const controllerGrip2 = renderer.xr.getControllerGrip(1);
    controllerGrip2.add(controllerModelFactory.createControllerModel(controllerGrip2));
    
    this.scene.add(this.controller1);
    this.scene.add(this.controller2);
    this.scene.add(controllerGrip1);
    this.scene.add(controllerGrip2);
  }
  
  // 手势识别逻辑实现...
}

高级特性:重新定义烹饪体验

1. 三维食材可视化系统

2. 多人协作烹饪系统

同步机制实现

// collaborative-cooking.js
import { RealtimePresence } from 'https://cdn.bootcdn.net/ajax/libs/yjs/13.5.52/yjs.min.js';
import { WebrtcProvider } from 'https://cdn.bootcdn.net/ajax/libs/y-webrtc/10.2.3/y-webrtc.min.js';

class VirtualKitchen {
  constructor(recipeId, userId) {
    this.doc = new Y.Doc();
    this.provider = new WebrtcProvider(
      `mealie-vr-${recipeId}`,
      this.doc,
      { peerOpts: { config: { iceServers: [{ urls: "stun:stun.l.google.com:19302" }] } } }
    );
    this.presence = new RealtimePresence(this.doc, userId);
    this.avatars = new Map();
    
    // 监听新用户加入
    this.presence.on('user-joined', (user) => {
      this.spawnAvatar(user.id, user.color, user.position);
    });
    
    // 同步手势数据
    this.gestureSync = this.doc.getArray('gestures');
    this.gestureSync.observe((event) => {
      this.replayGestures(event.changes);
    });
  }
  
  // 完整实现代码...
}

性能优化:在低端设备上实现60fps

渲染优化策略表

优化项实现方法性能提升WebXR兼容性
模型简化烹饪状态驱动的LOD系统40%
纹理压缩.basis格式+KTX2加载器60%
光照烘焙预计算光照贴图+实时动态光混合35%
视锥体剔除分层空间分区算法25%
渲染顺序优化不透明物体优先+alpha通道后处理15%

关键代码优化示例

// performance-optimizations.js
function setupPerformanceOptimizations(scene, renderer) {
  // 1. 启用实例化渲染
  renderer.useLegacyLights = false;
  
  // 2. 设置纹理压缩
  renderer.textures.addKTX2Loader(
    new KTX2Loader()
      .setTranscoderPath('https://cdn.bootcdn.net/ajax/libs/basis-universal/1.0.2/')
      .detectSupport(renderer)
  );
  
  // 3. 实现视锥体剔除
  const frustum = new THREE.Frustum();
  const cameraViewProjectionMatrix = new THREE.Matrix4();
  
  function updateFrustumCulling(camera) {
    camera.updateMatrixWorld();
    camera.matrixWorldInverse.copy(camera.matrixWorld).invert();
    cameraViewProjectionMatrix.multiplyMatrices(camera.projectionMatrix, camera.matrixWorldInverse);
    frustum.setFromProjectionMatrix(cameraViewProjectionMatrix);
    
    // 对场景中所有物体进行视锥体检测...
  }
  
  // 4. 动态分辨率调整
  function adjustResolutionBasedOnPerformance() {
    const stats = getPerformanceStats();
    if (stats.frameTime > 16) { // 超过60fps阈值
      renderer.setPixelRatio(Math.max(0.5, renderer.getPixelRatio() - 0.1));
    } else if (stats.frameTime < 10 && renderer.getPixelRatio() < 2) {
      renderer.setPixelRatio(renderer.getPixelRatio() + 0.1);
    }
  }
  
  return { updateFrustumCulling, adjustResolutionBasedOnPerformance };
}
