Instant Skinned Gaussian Avatars

This is the official repository for Instant Skinned Gaussian Avatars for Web, Mobile and VR Applications (SUI 2025 Demo Track).

🎉 We’ve released sample avatars and original scan data!
Check out the Sample Avatars section below for details.

Gaussian-VRM

Gaussian-VRM (GVRM) is a three.js implementation of Instant Skinned Gaussian Avatars. GVRM is built on top of three-vrm and gaussian-splats-3d. GVRM can handle avatars as standard three.js objects, allowing you to directly reuse VRM format avatar operations (such as movement and animations).

For detailed usage instructions, please check 👉 Gaussian-VRM Examples 👈

Quick Example

// GVRM
const gvrm = await GVRM.load('./assets/author.gvrm', scene, camera, renderer);  // 1/3
await gvrm.changeFBX('./assets/Idle.fbx');  // 2/3

renderer.setAnimationLoop(() => {
  gvrm.update();  // 3/3
  renderer.render(scene, camera);
});

The three steps are:

1. Load GVRM file
2. Change animation
3. Update every frame

That's all! (Super easy!) The full JavaScript code can be seen below:

import * as THREE from 'three';
import { GVRM } from 'gvrm';

const canvas = document.getElementById('canvas');
const renderer = new THREE.WebGLRenderer({ canvas });
renderer.setSize(640, 480);

const scene = new THREE.Scene();

const camera = new THREE.PerspectiveCamera(65, 640 / 480, 0.01, 100);
camera.position.set(0, 0.4, 1.5);

// GVRM
const gvrm = await GVRM.load('./assets/author.gvrm', scene, camera, renderer);  // 1/3
await gvrm.changeFBX('./assets/Idle.fbx');  // 2/3

renderer.setAnimationLoop(() => {
    gvrm.update();  // 3/3
    renderer.render(scene, camera);
});

Sample Avatars

Six sample avatars and original scan data are available on Google Drive: 🔗 Sample Avatars (Google Drive)
These avatars are released under the MIT License, as long as they are not used in ways that violate public order or morality.

Extra Animation Files

If you would like to use animation files with the sample avatars, the easiest way is to download them from Mixamo.

Recommended download settings:

• Format: FBX ASCII (.fbx)
• Skin: Without Skin
• Frames per Second: 60
• Keyframe Reduction: None
