4. WebAR Development Practice

Basic Example: Marker AR

// Implement marker tracking with AR.js
<a-scene embedded arjs>
  <a-marker preset="hiro">
    <a-box position="0 0.5 0" material="color: red;"></a-box>
  </a-marker>
  <a-entity camera></a-entity>
</a-scene>

Image Tracking Example

// Implement image tracking with Mind AR
import { MindARThree } from 'mind-ar/dist/mindar-image-three.prod.js';

const mindarThree = new MindARThree({
  container: document.body,
  imageTargetSrc: './targets.mind'
});

const { renderer, scene, camera } = mindarThree;

// Add 3D model
const loader = new GLTFLoader();
loader.load('./model.gltf', (gltf) => {
  const model = gltf.scene;
  const anchor = mindarThree.addAnchor(0);
  anchor.group.add(model);
});

await mindarThree.start();
renderer.setAnimationLoop(() => {
  renderer.render(scene, camera);
});

Face Tracking Example

// Implement face tracking with Mind AR
import { MindARThree } from 'mind-ar/dist/mindar-face-three.prod.js';

const mindarThree = new MindARThree({
  container: document.body,
});

const { renderer, scene, camera } = mindarThree;

// Add glasses model
const anchor = mindarThree.addAnchor(168); // Nose bridge position
const loader = new GLTFLoader();
loader.load('./glasses.gltf', (gltf) => {
  anchor.group.add(gltf.scene);
});

await mindarThree.start();

5. Performance Optimization

Model Optimization

• Polygon Count: Keep under 20-30k polygons for mobile
• Texture Size: Single texture max 1024x1024
• Model Format: Use GLTF/GLB format
• Compression: Use Draco compression

Loading Optimization

// Progressive loading
const loadingManager = new THREE.LoadingManager();
loadingManager.onProgress = (url, loaded, total) => {
  const progress = (loaded / total) * 100;
  updateProgressBar(progress);
};

// Preload critical assets
const preloadAssets = async () => {
  await Promise.all([
    loadModel('./model.gltf'),
    loadTexture('./texture.jpg'),
    loadTargets('./targets.mind')
  ]);
};

Rendering Optimization

• Lower Resolution: Adjust based on device performance
• Simplify Materials: Reduce lighting calculations
• LOD: Switch model detail based on distance
• Frame Rate Control: Maintain 30-60 FPS

6. Compatibility Handling

Browser Support Detection

// Detect WebXR support
if ('xr' in navigator) {
  navigator.xr.isSessionSupported('immersive-ar')
    .then((supported) => {
      if (supported) {
        // WebXR AR supported
        initWebXR();
      } else {
        // Fallback to other solutions
        initFallback();
      }
    });
} else {
  // WebXR not supported
  showUnsupportedMessage();
}

Fallback Solutions

• No AR Support: Display 3D model preview
• Insufficient Performance: Reduce model quality
• Camera Permission Denied: Prompt user authorization
