一、核心架构设计

MCP Inspector VR测试环境采用分层架构，实现前端与后端的松耦合集成：

mermaid

关键技术栈：

前端框架：React + TypeScript
3D渲染：Three.js (r160.0)
WebXR支持：@types/webxr (0.5.16)
MCP SDK：@modelcontextprotocol/sdk (最新版)

二、环境搭建与依赖管理

项目初始化：

# 创建React应用
npx create-react-app mcp-vr-inspector --template typescript

# 安装核心依赖
cd mcp-vr-inspector
npm install three@0.160.0
npm install @types/webxr@0.5.16
npm install @modelcontextprotocol/sdk@latest

构建配置（vite.config.ts）：

import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';
import { resolve } from 'path';

export default defineConfig({
  plugins: [react()],
  build: {
    rollupOptions: {
      input: {
        main: resolve(__dirname, 'index.html'),
        vr: resolve(__dirname, 'src/vr-entry.html')
      },
      output: {
        manualChunks: {
          threejs: ['three'],
          webxr: ['@types/webxr'],
          vrcomponents: [
            './src/components/vr/VRTestPanel.tsx',
            './src/components/vr/MCPVRDataSync.tsx'
          ]
        }
      }
    }
  },
  define: {
    __VR_SUPPORT__: JSON.stringify(true)
  },
  optimizeDeps: {
    include: ['three', '@types/webxr']
  }
});

三、核心功能实现

1. Three.js 3D可视化引擎

// client/src/components/VRTestPanel.tsx
import React, { useEffect, useRef, useState } from 'react';
import * as THREE from 'three';
import { VRButton } from 'three/addons/webxr/VRButton.js';
import { MCPConnection } from '@/lib/hooks/useConnection';

export const VRTestPanel: React.FC<{ connection: MCPConnection; resourceId?: string }> = ({ connection, resourceId }) => {
  const containerRef = useRef<HTMLDivElement>(null);
  const [isVRMode, setIsVRMode] = useState(false);
  
  // Three.js核心对象
  const scene = useRef(new THREE.Scene());
  const camera = useRef(new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000));
  const renderer = useRef<THREE.WebGLRenderer | null>(null);
  
  // 初始化Three.js场景
  useEffect(() => {
    if (!containerRef.current) return;
    
    // 创建渲染器
    renderer.current = new THREE.WebGLRenderer({ antialias: true });
    renderer.current.setSize(containerRef.current.clientWidth, containerRef.current.clientHeight);
    renderer.current.xr.enabled = true;
    containerRef.current.appendChild(renderer.current.domElement);
    
    // 添加VR进入按钮
    const vrButton = VRButton.createButton(renderer.current);
    containerRef.current.appendChild(vrButton);
    
    // 设置相机位置
    camera.current.position.z = 5;
    
    // 添加环境光
    const ambientLight = new THREE.AmbientLight(0xffffff, 0.5);
    scene.current.add(ambientLight);
    
    // 窗口大小调整处理
    const handleResize = () => {
      if (!containerRef.current || !camera.current || !renderer.current) return;
      
      camera.current.aspect = containerRef.current.clientWidth / containerRef.current.clientHeight;
      camera.current.updateProjectionMatrix();
      renderer.current.setSize(containerRef.current.clientWidth, containerRef.current.clientHeight);
    };
    
    window.addEventListener('resize', handleResize);
    
    // 渲染循环
    const animate = () => {
      renderer.current?.setAnimationLoop(() => {
        renderer.current?.render(scene.current, camera.current);
      });
    };
    
    animate();
    
    return () => {
      window.removeEventListener('resize', handleResize);
      containerRef.current?.removeChild(renderer.current?.domElement as Node);
      containerRef.current?.removeChild(vrButton);
      renderer.current?.dispose();
    };
  }, []);
  
  // 其他逻辑省略...
  
  return (
    <div className="vr-test-panel" ref={containerRef} style={{ width: '100%', height: '500px' }}>
      {!isVRMode && (
        <div className="vr-hint">
          点击"ENTER VR"按钮进入虚拟现实模式
        </div>
      )}
    </div>
  );
};

2. WebXR设备适配与交互

// client/src/lib/webxr/vrSessionManager.ts
import { useEffect, useState, useCallback } from 'react';

export type XRDeviceType = 'headset' | 'handheld' | 'none';
export type XRInputSource = { id: string; type: 'gamepad' | 'hand' | 'pointer'; controller?: THREE.Group };

export const useXRSession = () => {
  const [isSupported, setIsSupported] = useState(false);
  const [isSessionActive, setIsSessionActive] = useState(false);
  const [deviceType, setDeviceType] = useState<XRDeviceType>('none');
  const [inputSources, setInputSources] = useState<XRInputSource[]>([]);
  
  // 检测WebXR支持
  useEffect(() => {
    if (navigator.xr) {
      navigator.xr.isSessionSupported('immersive-vr')
        .then(supported => {
          setIsSupported(supported);
          if (supported) setDeviceType('headset');
        });
    }
  }, []);
  
  // 创建XR会话
  const startXRSession = useCallback(async (renderer: THREE.WebGLRenderer) => {
    if (!isSupported || isSessionActive) return;
    
    try {
      const session = await navigator.xr.requestSession('immersive-vr', {
        requiredFeatures: ['local-floor', 'hand-tracking'],
        optionalFeatures: ['layers', 'anchors']
      });
      
      renderer.xr.setSession(session);
      session.addEventListener('end', () => setIsSessionActive(false));
      setIsSessionActive(true);
      
      return session;
    } catch (error) {
      console.error('XR session failed:', error);
      return null;
    }
  }, [isSupported, isSessionActive]);
  
  // 其他逻辑省略...
  
  return {
    isSupported, isSessionActive, deviceType, inputSources, startXRSession
  };
};

3. MCP数据同步与可视化

// client/src/lib/threejs/mcpDataConverter.ts
import * as THREE from 'three';
import { ResourceUpdatedNotification } from '@modelcontextprotocol/sdk/types';

export class MCPDataConverter {
  private objectCache: Map<string, THREE.Object3D> = new Map();
  
  convertResource(data: ResourceUpdatedNotification): THREE.Object3D | null {
    const resourceId = data.ref.id;
    
    if (this.objectCache.has(resourceId)) {
      return this.updateExistingObject(resourceId, data);
    }
    
    switch (data.type) {
      case 'mesh':
        return this.createMeshObject(resourceId, data);
      case 'point-cloud':
        return this.createPointCloud(resourceId, data);
      default:
        console.warn(`Unsupported resource type: ${data.type}`);
        return null;
    }
  }
  
  private createMeshObject(resourceId: string, data: any): THREE.Mesh {
    const geometry = new THREE.BoxGeometry(
      data.properties.size?.x || 1,
      data.properties.size?.y || 1,
      data.properties.size?.z || 1
    );
    
    const material = new THREE.MeshStandardMaterial({
      color: data.properties.color || 0x00ff00,
      transparent: data.properties.opacity !== undefined,
      opacity: data.properties.opacity ?? 1
    });
    
    const mesh = new THREE.Mesh(geometry, material);
    mesh.position.set(data.position?.x || 0, data.position?.y || 0, data.position?.z || 0);
    mesh.userData.resourceId = resourceId;
    
    this.objectCache.set(resourceId, mesh);
    return mesh;
  }
  
  // 其他方法实现省略...
}

4. 性能优化策略

// client/src/lib/threejs/VRPerformanceOptimizer.ts
import * as THREE from 'three';

export class VRPerformanceOptimizer {
  private renderer: THREE.WebGLRenderer;
  private scene: THREE.Scene;
  private camera: THREE.Camera;
  private settings: {
    enableLOD: boolean;
    enableInstancing: boolean;
    enableFrustumCulling: boolean;
    maxFrameRate: number;
    resolutionScale: number;
  };
  
  constructor(
    renderer: THREE.WebGLRenderer,
    scene: THREE.Scene,
    camera: THREE.Camera,
    settings?: Partial<typeof VRPerformanceOptimizer.prototype.settings>
  ) {
    this.renderer = renderer;
    this.scene = scene;
    this.camera = camera;
    
    this.settings = {
      enableLOD: true,
      enableInstancing: true,
      enableFrustumCulling: true,
      maxFrameRate: 90,
      resolutionScale: 1.0,
      ...settings
    };
    
    this.applyPerformanceSettings();
  }
  
  applyPerformanceSettings(): void {
    this.renderer.setPixelRatio(window.devicePixelRatio * this.settings.resolutionScale);
    this.scene.frustumCulled = this.settings.enableFrustumCulling;
  }
  
  // 其他优化方法省略...
}

四、部署与扩展

1. 生产环境构建

# 构建优化的生产版本
npm run build

2. 性能监控组件

// client/src/components/vr/VRPerformanceMonitor.tsx
import React, { useEffect, useRef, useState } from 'react';

export const VRPerformanceMonitor: React.FC<{ optimizer: VRPerformanceOptimizer }> = ({ optimizer }) => {
  const [performanceData, setPerformanceData] = useState({
    fps: 0, frameTime: 0, objectCount: 0, triangleCount: 0
  });
  
  useEffect(() => {
    const interval = setInterval(() => {
      const stats = optimizer.analyzeAndOptimize();
      setPerformanceData({
        fps: stats.fps,
        frameTime: stats.frameTime,
        objectCount: stats.objectCount,
        triangleCount: stats.triangleCount
      });
    }, 1000);
    
    return () => clearInterval(interval);
  }, [optimizer]);
  
  return (
    <div className="vr-performance-monitor" style={{
      position: 'absolute', bottom: '20px', right: '20px',
      backgroundColor: 'rgba(0,0,0,0.7)', color: 'white',
      padding: '10px', borderRadius: '8px', fontSize: '12px'
    }}>
      <div>FPS: {performanceData.fps.toFixed(1)}</div>
      <div>帧时间: {performanceData.frameTime.toFixed(1)}ms</div>
      <div>对象数: {performanceData.objectCount}</div>
    </div>
  );
};
