Lightweight WebGL Renderer - Real-time 3D Gaussian Splatting Render Engine for LAM and LAM_Audio2Expression.

Our rendering engine is now available as an NPM package.

1. Install dependencies

   npm install

2. Run development server

   npm run dev

3. Open in browser

https://localhost:5173/

✨ Key Highlights

• Real-time rendering support: Interactive LAM avatars with LAM_Audio2Expression facial animations
• NPM package integration: Use with npm install gaussian-splat-renderer-for-lam

npm install gaussian-splat-renderer-for-lam

    import * as GaussianSplats3D from 'gaussian-splat-renderer-for-lam';
    const div = document.getElementById('GaussianRenderer');
    const assetPath = './asset/arkit/p2-1.zip'; //the real asset address
    const render = await GaussianSplats3D.GaussianSplatRenderer.getInstance(div, assetPath);

💡 Advanced Features

• Facial animations: Load /asset/test_expression_1s.json for expression control
• Custom avatars: Generate new models via LAM and replace ZIP files

The demo shows that LAM_Audio2Expression leverages audio input to generate ARKit blendshapes-driven facial expressions, powering ultra-realistic 3D avatars generated by LAM, and rendered with this render engine.

The demo highlights a low-latency SDK for real-time interactive chat avatars, developed using the same rendering engine as the core framework.

• Avatar model: ./asset/arkit/p2-1.zip
• Expression data: ./asset/test_expression_1s.json
